Are we at the apex of solar development?

W

ell, maybe not, but many of us were at the APEX Electronics meeting in Las Vegas last month (www.ipcapexexpo.org). There is increasing interest from the EMS community and the electronics business in general as they realize that solar uses more silicon than ICs, the area of solar panels produced now outstrips the area of circuit boards produced, and many members of the electronics supply chain are now heavily involved in this very materials-intensive business.

I had the privilege of presenting the iNEMI solar PV roadmap and being interviewed online (http://realtimewith. com/pages/videos.cgi?&rtwsid=44). I also had a chance to see great presentations

by Phil Plonski of Prismark and Dongkai Shangguan of Flextronics and talk to several experts in the field, including John Custer-Topai, as well as meeting with the companies at the solar pavilion including Celestica, Burkle and Bombard (who had a trailer-mounted, four-panel array powering the solar pavilion). Unfortunately the NREL solar team was a no-show due to travel restrictions brought on by the Federal continuing resolution. Expect a

number of follow-up articles!

There was a lot of discussion and concern about the potential for a growth slowdown in 2011-12. Many of the forecasts were published earlier this year before the Fukushima tragedy, and the new consensus is we may not see a significant drop even with the predicted overcapacity being put in place right now as more governments, companies and individuals vote for solar PV with their wallets.

The electronics industry supply chain has certainly caught on to the potential of the solar industry. For the iNEMI roadmap presentation I prepared the slide below to outline the links to the solar supply chain— and they are comprehensive!

The solar PV industry is becoming a very significant consumer of materials of all types and we can expect to see increasing competition from suppliers intent on increasing output and reliability while reducing cost. We’ll keep track of these suppliers from diverse industrial backgrounds and make sure Global Solar Technology readers are aware of the latest opportunities!

Shifting landscape for regional PV manufacturing

Shifting landscape for regional PV manufacturing

Regional Manufacturing Market Share 60%

% of Global Shipments

T

he global PV industry has grown at an extraordinary pace, with volume of shipments increasing by an average of 47% p.a. since 1997 (Navigant Consulting). That period of growth has also seen some dynamic changes in the regional patterns of manufacturing, as shown in Chart 1.

The U.S. was the world’s leading PV manufacturing market through the mid1990s, representing 47% of global PV shipments in 1997, at a point in time when the total world market was only 114 MW. Key policies that led to U.S. early leadership in PV manufacturing included support from DOE for basic and applied PV technology research as well as state-level economic development incentives, some of which were specifically tailored to attract PV manufacturing. A key shortcoming of the U.S. policies was the inconsistency of incentives for end-users. Many of the utility-sponsored PV rebate programs were pared back in the early 1990’s as a part of the transition to deregulated energy markets in many states, and the rebate programs that remained had limited funding and significant risk of funding cuts from year to year. The result of these “stop and start” funding cycles for PV was that PV manufacturing investments in the U.S. were subject to significant policy risk, hindering investment.

Beginning in the mid-1990’s Japan began to increase its market share, largely as a result of a “demand-pull” PV policy introduced by the Japan government that established an ambitious long-term target for PV installations in the country, 5 GW cumulative installations by 2010. At the

same time, the government, through METI’s New Energy Foundation, introduced an ambitious rebate program for residential PV investors. This up-front rebate was set at a level that paid for approximately 50% of the then-current cost of residential PV systems, and significantly, the government signaled to Japanese industry that the funding for the incentive program would be maintained and expanded in following years, with a reduction in the rebate level each year. The results were remarkable, and illustrated the positive impact of policy stability in spurring market expansion and cost reduction, as shown below.

At the same time, this market growth and stability coincided with a surge in investment in PV manufacturing capacity

by Japanese suppliers. By 2004, 10 years after the PV incentive program had been launched, Japanese manufacturers

represented well over 50% of total PV shipments. Over the past five years, Japan has lost its manufacturing market share leadership for several reasons, including a shortage of polysilicon, and the growth of manufacturing bases first in Europe and then in Asia, serving explosively-growing markets in Europe.

Building upon the momentum of the successful Japanese rooftop PV incentive program in the late 1990’s, policy-makers in Germany introduced a restructured feed-in-tariff program in 2000, with solarspecific tariff rates, 20-year tariff contracts and a structure of annual digressions intended to provide a “glide path” to grid parity. The result of this policy was an unprecedented growth in investment and market expansion, accelerated further as other countries in Europe, Asia and even Continued on page 8

North America adopted similar feed-intariff programs to meet renewable and solar energy policy goals. The feed-intariff policies have been the foundation for the majority of the global market growth over the past decade. The impact of these policies on regional manufacturing investments is less clear, as shown in Chart 2. Market share for European PV cell manufacturers increased from under 20% to over 30% in the first five years following the introduction of feed-in-tariff policies in Germany; however manufacturing market share for Europe remained static for the following several years, and beginning in 2009 declined rapidly as a result of new competition from low-cost high-volume cell and module manufacturers based in China and other Asian countries.

The past five years have seen a very changed landscape form for global PV manufacturing. Notwithstanding the continuing demand pull in a growing number of markets in Europe, the majority of new manufacturing capacity expansion has been in China and Asia. Some of the

factors driving this shift are economic, e.g. lower cost of capital, lower tax rates and lower cost of materials, labor and equipment. Other factors are policy-related, as regional and national governments have offered generous tax and grant concessions to help new and expanding PV manufacturers. The results have been dramatic. For example, the regional share of cell manufacturing for China/Taiwan has grown from less than 10% in 2005 to over 50% in 2010; shipments grew from less than 100 MW in 2005 to over 9,000 MW in 2010 (cf. Navigant Consulting).

Over the same time period the market share for “Rest of World” (chiefly Asia) has tripled.

What will be the key trends in the future, and what are the key factors for determining regional investment in PV manufacturing? For crystalline PV, new cell manufacturing demand will likely be met by further scale-up of existing cell manufacturing facilities, a trend that will also be reinforced by favorable availability and cost of capital in China and Asia.

Chart 3. Estimated cost of production for a Micromorph® thin film silicon module.

www.globalsolartechnology.com

Module manufacturing investments are likely to be more regionally dispersed and located in proximity to leading long term markets, e.g. U.S. Thin film technologies may follow a different pattern. Recent announcements

by First Solar and GE exemplify a potential counter-trend, with thin film manufacturing being located in or near to key end markets. The U.S. is a particularly interesting case because in recent years the market share for thin film has been much higher than the global average. For example 44% of total U.S. PV installations in 2010 used thin film technologies.

Furthermore, thin film manufacturing is highly automated, so that the cost of labor is a relatively minor factor, while the cost of materials (primarily gases and glass) is a more critical factor. To illustrate this, Chart 3 shows the estimated cost of production for a Micromorph® thin film silicon module produced on an Oerlikon Solar ThinFab line (120 MW capacity).

Note that the figures shown do not include the cost of financing, so there may still be significant variations between regions if there are significant disparities in the cost of financing.

There have been a number of policy initiatives introduced in recent years designed to stem the shift of manufacturing to Asia, including new domestic content requirements (e.g. Ontario) and new grant initiatives to support emerging technologies through the “valley of death” of early commercial ramp-up (e.g. U.S. DOE). While market protection policies are understandable in a subsidized solar energy market, policymakers also need to bear in mind the demonstrated efficiencies and cost savings that have resulted through global competition in the PV industry over the past five years, and ensure that supported domestic manufacturing is competitive and providing end customers with the most affordable solar energy costs.

Canada’s largest solar roof installation

Canada’s largest solar roof installation

I

n June 2009, Kitchener City Council approved the installation of a 500kW/h solar energy system on a portion of the 300,000 square-foot roof of the city’s future consolidated maintenance facility— a project that has put Kitchener on the map as the home to the largest solar-panel installation in Canada. Now fully installed and with the official launch planned for later this spring, the city will own, operate and maintain the solar-energy system—consisting of 2,660 photovoltaic solar panels, with each producing 200 W of power— and sell all generated power to the Ontario Power Authority under a 20-year contract.

Design was done by Arise Technologies of Waterloo. Permits were obtained by the City of Kitchener and the solar panels

8 – Global Solar Technology – May 2011

have been manufactured and installed by Photowatt Ontario of Cambridge, Ontario.

City of Kitchener Facilities Management Staff will carry out ongoing maintenance.

In addition to the environmental benefits of owning and operating its own power provider would bring, this project will also diversify the city’s future electricity supply through the application of a leading-edge energy-generation technology in a costeffective manner. The total cost of the intended solar-energy system installation is approximately $4.1 million, which has been funded through a three-way partnership between the Government of Canada, the Province of Ontario and the City of Kitchener, as part of a national infrastructure stimulus program, as well as the city’s

Local Environmental Action Fund (LEAF), a $5-million program aimed at reducing or repairing our city’s impact on the environment. The Federation of Canadian Municipalities also contributed more than $4,500 from its Green Municipal Fund, which helped cover project-related consulting fees. The solar roof is expected to generate more than $363,900 in net revenue for the city each year - and more than $3.5 million over the course of the 20-year contract with the OPA. “The city can make a meaningful contribution to fighting climate change by reducing our future greenhouse-gas emissions through a community-scaled renewable roof-top solar energy Project which replaces fossil fuel combustion,” said Terry

Canada’s largest solar roof installation

Kitchener, Ontario’s 300,000 ft2, 500 kW/h system Boutilier, a senior business development officer with the city. “This investment is a clear demonstration of the city’s commitment to its environmental goals; and it reflects the wishes of the citizens of Kitchener, as expressed through the several community consultations which have been conducted.”

Kitchener is one apex of Canada’s Technology Triangle (www.techtriangle. com) in the Waterloo Region of Ontario.

With homegrown global leaders like Research In Motion, Toyota, Christie Digital Systems, and Enermodal it is no wonder that global solar companies such as Photowatt Ontario, Arise Technologies, and Canadian Solar, choose to locate in this Region. No other community in Canada

www.globalsolartechnology.com

has a solar cluster quite like the Waterloo Region.

Ideally located for business set up and expansion, Waterloo Region is situated on Canada’s superhighway 401, and close to major population centers. In addition there is a substantial home market in Ontario for CleanTech driven initiatives.

• The Ontario government plans to retire 7,000 MW of coal-fired generation by 2014.

• The Green Energy and Green Economy Act, passed in 2009, makes Ontario a global renewable energy leader with an attractive Feed-in Tariff Program.

• The solar FIT rates are competi-

tively priced between 44.3 ¢/kWh and 80.2 ¢/kWh. The system has been turned on as of March 25, 2011. The official ribbon cutting will take place in the last week of May. What advice would Terry Boutilier give to other municipalities looking to install a project of this type?

“Complete a comprehensive business case prior to ‘jumping in’ to a project of this nature. Retain experienced design and construction people.”

Company profile: OSP—Ontario Solar Provider

Company profile: OSP—

Ontario Solar Provider

I

n our series of articles and interviews with leaders of the Canadian solar business throughout the supply chain, I have been really impressed by the spirit, enthusiasm and creativity of the companies and people I have met. OSP is a shining example of a company that saw a need and “went for it!”

I talked to Christian Wentzel and Thomas Kreutzer about the company and its formation.

OSP’s roots are in Germany, like a few of the new solar companies in Ontario.

Christian is a financial expert with experience in renewable and traditional energy investments. His business partner, Sebastian Seyfarth, has experience in largescale ground mount solar development.

Both partners have extensive global business experience. Together they identified an opportunity in Ontario in September 2009, seeing an opportunity to transform the existing solar business—cottages and lake houses with no grid connection—to a significant business due to the attractive feed in tariffs and domestic content requirements then being proposed in Ontario. They moved to Ontario and met Thomas—with over 350 solar PV installations under his belt—through a craigslist posting(!). The rest is history.

When they arrived, the Canadian business was in a really early stage compared to the more mature market in Germany.

There was difficulty sourcing local content, and a major shortage of skilled installers and project managers. With two module makers up, two more on the way and five more potential suppliers, OSP is comfortable that the local supply shortage will ease.

There is still a real shortage of skilled personnel, though, and OSP continues to bring in resources from Germany.

There have been a number of other challenges in the start-up period. The slow approval process is quite different than the mature German system. The OPA (Ontario Power Authority) adds another layer of regulation to the process, and the sheer level of applications—over 20,000, apparently being processed by only a few people—is choking the system. The Ontario Provincial Government is aware of this and is working to streamline the process.

10 – Global Solar Technology – May 2011

Alan Rae recently spoke with OPS’s Thomas Kreutzer and Christian Wentzel.

Left to right: Sebastian Seyfarth, Christian Wentzel and Thomas Kreutzer.

The lack of skilled installers and project managers—with virtually no barriers to entry, no certification or qualifications required—makes it tough to sort out the good installers from the “cowboys.”

OSP is an integrator concentrating on large-scale turnkey installations—commercial rooftops from 100 KW to 5 MW, and the development of utility ground

mount farms from 5 MW to 10 MW. Roof strength in general has been a vexing issue—design strength capabilities of 2-3 lb/square foot did not fit well with ballasted systems at 5-10 lb per square foot. OSP encouraged KB Racking, a company with a novel lightweight racking system, to set up in Canada to supply the roof mount market Continued on page 13

Company profile: OSP Continued from page 10 Connection issues also exist, and these are being addressed by The Canadian Solar Industries Association, www.cansia.ca, where OSP is one of the two industry representatives on the working group.

The impact of solar feed-in on the grid is being calculated very conservatively (for example, not assuming power generated in an industrial park may well be consumed 100% in that park), which is restricting grid capacity. Other countries use a less conservative model that works well in practice, and the group is working towards finding a workable solution that will maintain grid integrity and strong growth of the solar sector. The restrictions also assume older inverter technology which is now outdated.

Financing is another area where Christian’s skills have come to bear, in developing a number of financing options backed by German banks.

Recently, OSP announced a project with Dymon Power Corporation of Ottawa for eight rooftop installations totaling 2.7 MW with construction starting in April.

OSP has enthusiasm, experience and creativity—a great combination for a growing market!

percentage of electricity produced, Japan’s devastating earthquake has regenerated public awareness to the risks of nuclear power plants and the benefits of alternative energy, especially in highly populated regions, which are susceptible to natural disasters.

Worldwide solar photovoltaic installations have grown at an average of 65% y/y between 2004 and 2010 to a cumulative of 37,654 MW according to Needham & Company and photovoltaic revenues grew on a quarterly average of 66.9% in 2010 compared to electronic equipment revenues, which chugged along at an average of 12.9% during the same period (Chart 4). Needham’s forecast

2011 year over year growth is slowing as the worldwide “great recession” recovery gains traction. A composite of 55 publically traded solar/photovoltaic companies shows a 3/12 growth slowdown beginning in 2Q10 (Chart 1). A timelier monthly composite of Taiwan’s solar supply-chain manufacturers demonstrates a steep trajectory with a slight revenue slowdown in January 2011 (Chart 2).

The global “Purchasing Manager’s” index (Chart 3) is a leading indicator for the electronics manufacturing industry by 3-6 months. Electronics’ demand is a leading indicator of electricity usage and although solar energy represents a small

The forecast was based on anticipated FiT incentive changes but did not take into consideration a life-changing situation, such as an earthquake or a tsunami.

Japan’s “Purchasing Manager’s” (diffusion) index fell to under 50 in March, showing an unsurprising demand contraction (Chart 6).

tsunami (Chart 7) and a steep increase in energy (Chart 8) and commodity prices (Chart 9). Although the earthquakes and tsunami caused minimal damage to the solar/photovoltaic supply chain, radiation leaks from the nuclear reactors are increasing demand for safer, more readily available energy sources. In addition, the disaster is showing chinks in globalized JIT supply chain manufacturing which is testing contingency plans and creating a reallocation of suppliers (Charts 10 & 11).

Opportunities will arise from the disaster as companies replace equipment or expand capacity, but the most disruptive part of the situation is an inadequate electricity infrastructure that will take years to rebuild. Rolling blackouts have shut down plants, and radiation has rendered parts of the region a ghost town.

According to Goldman Sachs Group, replacing Japan’s proposed 108 GW of nuclear plants will provide opportunity for alternative energy sources (such as solar) that could equate to over US $150 billion

www.globalsolartechnology.com

(based on $1.40/watt for a large utility solar installation) over the next 20 years with roughly 72 GW (US $100 billion) needed in the next nine years.

Germany, Italy, China and the United States are also rethinking their reliance on nuclear energy, which can and should propel the global solar industry to another record year that will exceed all expectations.

Japan’s disaster has shown us how vulnerable we are to the existing infrastructure. Prices of used power generators and storage batteries have risen to 1.5 to 3 times their pre-quake levels.

Power shortage have affected component parts for electronic equipment including aluminum electrolytic capacitors used for PV inverter applications.

Process equipment forecasts

Solarbuzz research tallied solar equipment spending at US $3.7 billion in 1Q11 and believes that full year revenue will increase 41% y/y to $15.2 billion in 2011.

Unanticipated equipment replacement and capacity expansions as a result of Japan’s earthquake damage and enhanced awareness of nuclear radiation risk may bump up demand substantially.

Two recent initiatives making solar PV more user-friendly

Two recent initiatives making solar PV more user-friendly

C

entrosolar has been in the news recently because of two innovative programs, the CentroLease leasing program and the CentroData data monitoring system. Centrosolar Group AG is one of the leading publicly traded solar companies in Europe, with revenues of EUR 403M ($540M) in 2010 and over 1000 employees in 21 locations. Centrosolar has production facilities in Germany for its PV modules and components including solar glass. Centrosolar America, Inc., offers complete PV packaged kits— CentroPack®—along with branded PV modules, PV rooftop racking solutions and other balance-of system components like switchgear and inverters with full-scale distribution facilities in Arizona, California and New Jersey serving a national valueadded integrator network for the residential and commercial channels.

Firstly, the CentroLease Program, aimed at lowering financial barriers for homeowners.

Available first to installers in select states including Arizona, California and New Jersey, CentroLease is a leasing program designed to support the installation of Centrosolar’s proprietary, Germanengineered ‘solar-in-a-box’ system—the CentroPack, which comes standard with best-in-class components, an industryleading warranty, and a national service and logistics support network maintained

by Centrosolar across the United States.

With solar representing a major investment for most homeowners, leasing options have traditionally been available only through private financing or from installing firms that are product-agnostic. With the CentroLease program, homeowners now have an OEM leasing option backed by a leading global solar manufacturer.

The CentroLease program is a multiyear lease-financing product that includes: • Online tools that generate a customized lease proposal for homeowners • Straightforward application and convenience associated with point-

CentroData generates real-time reporting on PV system performance.

of-sale financing • Training and support for installers during the sales process • Standard CentroPack product platform including long-term monitoring solution • On-time delivery to installers from Centrosolar’s nationwide distribution network Secondly, the CentroData system offering high precision real time energy monitoring.

Centrosolar’s CentroData is a hardware and software application that generates real-time reporting on PV system performance. Installed near the PV system power inverter unit, and connected to a wall inside or outside of the home in a NEMA 3R enclosure, the system continuously monitors the solar system’s performance, while sending real-time data wirelessly using Ethernet over power line. This has gener-

ally proved much more reliable than using consumers’ WiFi or other wireless technologies but for remote locations a cellular system is also available. Previously able to send data only to an internet-connected device, CentroData has now been updated to a commercial grade energy meter and web-enabled portal that is designed to collect, store, and upload a wide range of energy data.

With a standard monitoring system, an accuracy of +-5% means that the system will monitor with result in measurements between 95% and 105% of actual production. The revenue grade CentroData energy meter will monitor a PV system with measurements between 99.5% and 100.5% of actual production. This enables solar installers and homeowners to monitor their solar system much more accurately than before, enabling them to measure return on their solar investment and energy sav-

Two recent initiatives making solar PV more user-friendly

ings in new ways. CentroData is also capable of monitoring and recording energy usage at the home or business.

This means that a user can see not only how much their PV system is generating, but also how much electricity they are consuming.

This is critical for accurate revenue projections, especially when multiple installations are being monitored.

With CentroView™, CentroData’s web-based portal program, homeowners can access their individual system solar performance data from the convenience of any computer, anywhere and at any time. By going to CentroView. net and using their login and password, they can view their data on-line in a computer-friendly dashboard screen format. Users can also create customized charts that track data ranging from the system’s daily output of solar generated electricity to the amount produced monthly, seasonally or over a full year. The equivalent dollar amounts of energy savings provided by the system as well as a measurement of the lessened impact on the environment made possible over the lifetime of the installation can also be tracked.

This summer, CentroData will offer homeowners the opportunity to view their solar system’s performance at their fingertips with a newly created mobile device App for iPhone and Android that, with a push of a button, allows the user to track real-time how many watts of energy the system is generating, that day’s output and usage, the annual savings realized, and much more.

The CentroData system automatically provides the output data needed to simplify the task of reporting the data required for solar renewable energy tax credits and project financers. The system generates real-time system diagnostics, as well, and sends alerts when the PV array performance drops below a target performance threshold, whether caused by excessive debris, unplanned shade, or adverse weather conditions.

Benchmarking of performance against other CentroSolar locations in the same area is another powerful diagnostic tool that can be employed.

So these systems can help finance your system, monitor its health and manage the revenue generated!

Tech focus: Future photovoltaic modules require innovatively designed junction boxes

Tech focus

Future photovoltaic modules require innovatively designed junction boxes Tremendous market growth within the solar power industry, together with the soaring pressure to increase manufacturing efficiency and reduce the associated production costs, are forcing producers of photovoltaic modules to automate their fabrication processes. In addition, these photovoltaic (PV) modules have to survive twenty-five year customer warranties and maintain high standards of performance throughout their lifetime.

T Keywords: Ceramic sheets 22 – Global Solar Technology – May 2011

wo important factors will be driving the future of PV module interconnections—assembly cost and connection reliability. The automated fabrication of PV modules improves efficiencies, product integrity and reduces production overhead. By using automated production lines, assembly time of a junction box to a PV panel can be reduced considerably. The introduction of new automated systems inevitably results in changed requirements in design of a mounting mechanism for an

electrical junction box.

In a PV module, the quality of the interconnections is often the most critical point for the performance and lifetime of the module. Many of the potential problems only show up after several years. If lower quality is employed, defective electrical connections may lead to a fire in the junction box. The Molex SolarSpec PV junction boxes are soldered to the PV panel ribbons, as in this case soldered connections are the safest and most reliable connection, rather

Tech focus: Future photovoltaic modules require innovatively designed junction boxes

than relying on clamped joints as they are still used in many manually assembled junction boxes.

Uli Schoettle, European industry marketing manager for the industrial market at Molex, introduces the SolarSpec junction box with an innovatively designed mounting mechanism. To address the issues relevant to the solar industry, Molex can call on a variety of well-established inhouse technologies and solutions that have already met the challenging requirements in many other industries, such as telecom and data systems, the automobile and commercial vehicle sector as well as in the factory and process automation segment.

Molex has already developed a range of interconnection products designed specifically for the solar industry. The SolarSpec range of solar-rated, UV-protected connectors and cordsets offers complete solutions for solar applications like solar panels, tracking systems and inverter connection systems.

Working closely with leading photovoltaic module manufacturers, Molex has added a PV junction box to its SolarSpec range developed specifically to ease assembly and to limit risks associated with process variation. This SolarSpec junction box is designed for fully automated module production. The primary goal is to offer a product that is universal, reliable and able to address a wide diversity of customer requirements while still allowing any customer-specific requirements to be implemented.

To achieve these objectives, Molex designed a completely new board termination system for the base part of the two-piece junction box. In the socket of

www.globalsolartechnology.com

the junction box there are solder terminals, which make direct contact with the exposed conductors of the PV panel. This enables the part to be easily positioned to the PV module by a pick and place machine or industrial robot. The contact springs are then soldered to the conductor by means of an automated solder process.

The Molex patented Solder Charge™ SMT technology is an additional integrated feature that allows simplification of the solder operation. Manual interventions such as up-righting, isolating and pre-positioning of the panel-side conductor strips are no longer required.

Molex Solder Charge™ SMT technology is tailored to connectors with contacts being in-line and gives much better reliability when it comes to solder joints and mechanical resistivity. The solder charge entails a flat, riveted terminal onto which a solder mass is stamped to provide a dense envelope for adhesion to a PCB or a conductor as used in a PV panel. During the soldering operation, the solder charge will melt completely around the terminal to create a conical joint. At the same time, solder adheres within the riveted hole in the contact for added retention forces.

The cover of the Molex SolarSpec junction box, which contains the bypass diodes connections, can simply be placed on top of the base that has already been installed on to the PV module. This operation can likewise be automated as part of the production sequence.

The cover and the socket of the SolarSpec junction box interlock via a clip mechanism positioned on the left and right-hand side of the unit. This assembly can be opened simply with a flat bladed

tool, such as a screwdriver. The clip mechanism also serves as a pre-centring aid so that the upper and lower sections can be easily brought together and securely interlocked during automatic placement.

Furthermore, the asymmetrical polarised arrangement of the locking clips prevents the upper section from being incorrectly fitted.

An optimised component layout within the Molex SolarSpec junction box ensures a smooth and uninterrupted component feed during the pick and place process, and the compact overall design guarantees precise positioning of the junction box on to the PV module. Another important factor in the design of the SolarSpec junction box is the optimisation of its external dimensions. Furthermore, reduced weight and a minimised component count also provides for an elegant and cost-effective solution and help to avoid the associated heat dissipation problems often encountered in less efficient assemblies.

The adhesion and sealing of the junction box on to the PV module is conventionally achieved by using silicone, which must be applied prior to mounting. In order to simplify the automated assembly of the box to the PV panel, Molex can preassemble a double-sided adhesive tape so that only the protective foil needs to be removed prior to mounting. This eliminates the time consuming application of silicone and, above all, the time required for the silicone to cure.

The Molex junction box complies with DIN EN 50521 for PV connectors and VVDE 0126-5 for PV junction boxes. The product has been approved by TUEV and UL. The ingress protection is IP65.

Filling a vacuum in Welland, Ontario

Filling a vacuum in Welland, Ontario

I

n the empty Fantom vacuum cleaner plant in Welland, Ontario, OSM has big plans to fill the needs of solar PV customers in Ontario and beyond. In this clean and renovated plant, they already have a 15 MW semi-automated line in place, with automated 15 MW and 20 MW lines on the way. The other vacuum? Demand is very strong as lack of local supply content is just starting.

Units being shipped are premium polycrystalline 60 cell modules with a guaranteed output of 230 W under the “Symphony” brand.

How has OSM been able to get up and running so quickly? We talked to Al Wiley, the project manager, an experienced manufacturing engineer who has been instrumental in this process.

How did you manage to get up and running before other new panel manufacturers in Ontario?

Our partnership with Symphony Energy in Korea is critical. They have provided the technology and are training our people for production and quality assurance—we have two shifts fully trained, and the training team is here as we are about to bring on a third. In addition, OSM is privately held and the investors are Symphony and local angels, so Symphony is committed to our success.

Module makers have to buy imported assembly units and these must be brought up to Canada’s very strict electrical code.

Now we have been down this learning curve it is easy and fast for us to bring in additional lines.

by the FIT differential in Ontario, keeping module size and weight down is critical. We plan to use the best available technology to increase output and we will be opening our R&D labs, headed by Dr. Taesung Kim, from Symphony Energy, who is relocating here. Dr Kim is a well-respected expert in the field, having worked with several types of cells and has 27 patents to his name.

How do you guarantee the performance of your modules?

Concerns?

We start by buying high output polycrystalline cells from NSP in Indonesia. We check them carefully, assemble them and test the modules and we have a comfortable margin over the rated 230 W. Do you plan to go to 72 cell modules?

We’d rather produce 60 cell modules with higher output—250 W and above. With an increasing emphasis on roof mount driven

24 – Global Solar Technology – May 2011

How about the support resources in Welland?

We have two excellent facilities in Niagara College—which has a PV lab—and Brock University. They will be our partners in growth.

The barrier for entry for installers is very low. Currently a pickup truck and a ladder.

PV installation is a skilled job, though with some challenges. Solar panels are live when sun is falling on them as you carry them up on to the roof for instance. Installers need to know this kind of information so they are safe. Another issue is connection standards. If the unit is not properly connected at the meter then back-feeding to the line can occur with potentially fatal conse-

quences to linesman fixing a break. We’re working with Welland Hydro to ensure that safe connection standards are developed.

From the customer’s perspective how would you like OSP to be seen?

We already supply modules and partner with inverter makers to provide matched units. Our aim is to provide customers high output high reliability and yet cost-effective systems going forward. This includes effective, efficient and matched balance of systems as well as strong links to research, education, and grid connection. We are already getting inquiries from the USA and Europe for our modules and plan to stay ahead of the curve as the business grows to supply Ontario’s needs and needs of customers in North America and beyond.

OSM has a compelling vision and a unique approach. Not content to use commodity cells to build a vanilla product, they have set clear goals on the way to becoming a major module manufacturer.

Lamination—no problem for Bürkle!

Lamination—no problem for Bürkle!

I

t is always fascinating to see technology crossovers. It’s surprising how often another industry has solved the problems facing your industry. Here we have a classic case of a company founded on wood lamination applying its technology to solar modules Bürkle North America, Inc., is a subsidiary company of Robert Bürkle GmbH, having its headquarters in Garden Grove, California. Bürkle is focused on two core technologies, coating and lamination, and serves the woodworking industry, the printed wiring board fabrication industry, the photovoltaic solar panel industry, and the plastic card fabrication industry. Bürkle is the pioneer in supplying multi-opening lamination lines into the PV Industry. More than 35 multi-opening lamination lines for the lamination of solar modules have been supplied since the market entry in 2008.

Bürkle is a 90-year-old company with three manufacturing facilities in Germany and sales and service offices around the world.

The group has a staff of 720 employees.

I talked to Dick Crowe, president and CEO of Bürkle North America, (who had interviewed me at APEX). I was fascinated by the way this company had carved out a really interesting niche in the market.

How did this business evolve?

Starting with wood lamination 91 years ago, we devised large-area, high-precision laminating processes that were later used in circuit board manufacture, credit card lamination and solar modules.

What is your technical emphasis?

Precise materials handling and thermal uniformity across the heated platen using oil heating.

Single-daylight easy-Lam®

26 – Global Solar Technology – May 2011

The multi-daylight Ypsator®

How did you get into solar PV? About 10 years ago we looked at the market, and at that time it was too small and not well enough developed for us. We revisited with an extensive market survey and decided that the time was now right to introduce lamination products that would yield statistically significant yield and throughput improvements.

How do you achieve these improvements?

It’s critical to manage pressure and heat uniformity over time. Our vacuum presses using membranes give uniform pressure without cracking the solar modules.

What types of presses do you sell?

“Single Daylight” (easy-Lam®) and “Multi Daylight” (Ypsator®). The single units have a cycle time of 17-20 minutes. Our multi units with four to 10 openings can increase throughput in proportion with the number of parallel stacked platens—up to 240 panels per hour depending on size.

How can you reduce cycle time?

We have a split cycle process that can further increase throughput by reducing the cycle time to 8-10 minutes, a reduction of 50%. The first part of the cycle applies vacuum, heat and pressure to start polymerization, and the polymerization is finished under pressure and heat with no vacuum. This can give an output of up to 144 panels per hour.

You mentioned materials handling as a strength?

We manage this within the laminators to minimize productive time. One load is ready to move as soon as the earlier load exits the process.

What’s next for Bürkle?

We are driven by the industry roadmaps and the development of local module manufacturing across the world. Silicon based systems will dominate (although we see significant developments from our thin film customers, especially CIGS), and so we feel we are well positioned for the next five years’ growth. We have shipped over 150 machines, and demand is strong. We have worldwide manufacturing and distribution, with, for example, six service engineers in North America.

We have other product lines we will bring on as needed, for example our easyCoater® novel glass coating system using a combination of grooved and solid pressure rollers to give an extremely uniform coating on glass across the entire width, something which is not possible to achieve with other technologies, such as spray. This technology is adaptable to a wide range of glass coatings for imaging, adhesion, optical modification, etc., for both thin film and crystalline silicon modules.

Bürkle shows nicely how a best-of breed supplier can develop a strong business in the growing solar PV market by bringing in the right products at the right time.

Tohoku earthquake amplifies need for low risk energy Technological developments

Technological developments Fraunhofer ISE produces world’s largest screenprinted dye solar cell module

Fraunhofer ISE produces world’s largest screen-printed dye solar cell moduleThe dye solar cell module is still a young photovoltaic technology. However, in the last few years, this technology has started to extend beyond the laboratory level. The ultimate aim is the successful integration of these solar modules into the building façade. A large challenge in the development of new photovoltaic technologies is the transfer from the laboratory to the industrial level. As a step in this direction, researchers at Fraunhofer ISE have succeeded in producing the worldwide first dye solar cell module on a continuous substrate material with dimensions of 60 x 100 cm². An important hurdle has been overcome.

In an extensive series of laboratory tests, the researchers at Fraunhofer ISE succeeded in manufacturing prototypes of large-area dye solar modules on glass.

is possible on a module area of 60 x 100 cm² using screen printing t e c h n o l o g y ,” explains a delighted Dr. Andreas Hinsch.

“This avoids a complex external connection of the submodules.

With this prototype, we have achieved a decisive step towards costeffective up-scaling and paved the way for the transfer to the industrial level.”

At Fraunhofer ISE, dye solar cell modules are manufactured with meander design. The glass frit sealing, stable over the long-term, is also applied by a screenprinting process. Dye modules open up new design possibilities for buildingintegrated façades and other decorative applications.

A short time ago, efficiencies of 7.1 percent, with respect to the active area, were reached at Fraunhofer ISE for dye solar cell modules of dimensions of 10 x 10 cm². The same manufacturing procedure was used for the small modules and the up-scaled modules.

Dye solar cells are photoelectrochemical solar cells. The conversion process is similar to photosynthesis. In principal, they are simple to manufacture and present a prime example for the research behind and the realization of functionalizing nanomaterials. Dye solar cells are based

on a nanocrystalline carrier layer made of titanium dioxide TiO2 whose surface is chemically bonded with dye molecules. A small amount of gel electrolyte is used for the transport of the carriers.

The manufacture of the 60 x 100 cm² modules was carried out using industryrelevant procedures and machines. For applying the dye and the electrolyte, a customized, in-house development was necessary. Therefore, in cooperation with the Fraunhofer IAO in Stuttgart, Fraunhofer ISE developed a station for automatically filling and sealing the large area dye solar cell modules. With this apparatus, the further manufacture of modules for future demonstration projects is guaranteed, and a decisive step towards a pilot processing line has been accomplished. Fraunhofer ISE is now considering plans for a spinoff company so that first demonstration systems can be realized.

The on-going work on dye solar cell modules at Fraunhofer ISE is carried out within joint projects sponsored by the Federal Ministry of Education and Research (BMBF), the European Commission and the Ministry of the Environment, BadenWu?rttemberg.

Fraunhofer ISE is the largest European solar energy research institute. For the past thirty years, Fraunhofer ISE has been working closely with industry to develop new technologies in the area of solar cells.

In addition to its focus on silicon solar cells, comprehensive research is being carried out on dye and organic solar cells as well as multi-junction and concentrator III-V semiconductor solar cells. 

licensed from Rice University, Natcore believes its device will revolutionize the way solar cells are manufactured. At present, solar cell manufacture involves an expensive chemical vapor deposition (CVD) method that requires a hightemperature vacuum furnace; highly toxic and flammable silane and other dangerous chemicals; and silicon disks of sufficient thickness to withstand the hightemperature firing.

Conversely, Natcore’s is a liquid phase deposition (LPD), or wet chemistry, process. It grows the AR coating in a warm chemical bath; eradicates the need for silane; dramatically reduces energy requirements; and significantly lowers silicon usage. The resulting solar cells will be less expensive and less environmentally harmful than conventional solar cells.

Natcore is producing its device at MicroTech Systems, Inc., a 15,000 sq.

ft. facility located in Fremont, CA. The 25-year-old Silicon Valley company designs and manufactures wet stations for solar, LED, semiconductor, biomedical, data storage and other high technology applications.

MicroTech’s intelligent process control will be integrated with Natcore’s LPD technology into a wet process platform.

Natcore’s intelligent LPD process station will be a totally enclosed system that contains a pre-clean subsystem for wafer cleaning before introduction of wafers into the LPD process; an LPD process subsystem incorporating Natcore’s latest sizing and process control input; and MicroTech’s latest drying module specifically designed for low metallic contamination, which is important for optimal solar performance.

But perhaps the major feature of the Natcore device will be its ability to monitor the coating process throughout. Specifically, it will use MicroTech’s spectrometer-based technology to accurately measure the thickness of the AR coating on a wafer while it is submerged in a chemical bath, and can alter the composition and duration of the bath in order to produce cells with greater simplicity and a high degree of precision.

Production will be conducted in two phases. The first phase, estimated to take approximately 8–10 weeks, will result in a manual development system, measuring about 8 ft. x 6 ft. x 6 ft., that will allow Natcore scientists to refine the coating process. At that point, Natcore scientists and MicroTech engineers will determine what changes need to be made and how much automation they want to add in the second and final phase. The final production system will measure about 20 ft. x 6 ft. x 8 ft. high. It will be a self-contained modular system capable of recycling its own effluents and of producing 3,000 AR-coated wafers/hour.

“This device will be adapted from existing, proven equipment already in wide use in industry, but will incorporate Natcore’s LPD technology in exciting new ways,” says Brien Lundin, Natcore’s chairman. “The testing that we will do on the initial equipment will have a goal of rapidly introducing our intelligent device into an existing solar cell fabrication line.

Dependent upon the results of that testing, we hope to have a product ready for sale in the near future.”

“We’re building our first production model in the U.S., rather than at our China joint venture, for reasons of time, quality, and logistics,” says Chuck Provini,

Natcore’s president and CEO. “We want to set the standard for quality and reliability.

By building it in California, we can keep a close eye on the machine’s development without the disruption created by a 12-hour time difference and the need to travel halfway around the world. And by choosing MicroTech, we are assured of the highest quality.”

“We have been impressed with Natcore’s vision of bringing cost effective Liquid Phase Deposition into solar cell manufacturing and are excited with the working relationship already established between the companies” says Tom Halloran, Microtech’s director of business development and program manager of Microtech.

“We believe that Natcore’ LPD technology truly provides a paradigm shift in driving the cost of solar manufacturing and we wanted to be an integral part of that solution. We feel privileged to have been chosen as the equipment development partner,” says Tom Vukosav, president and CEO of MicroTech Systems Inc. 

Renewable energy hybrid mini-grids to become mainstream solution for rural electrification

A new study demonstrates the market potential of mini-grids fed by hybridized renewable energies, especially when compared to diesel-based solutions in developing countries. This study, financed

by USAID and developed by the Alliance for Rural Electrification (ARE), is one of the most comprehensive to date on this energy solution.

Conclusions show that such minigrids are a cost-effective, reliable and sustainable means of supplying power to rural communities, especially in populated isolated areas where grid extension is too costly. When compared with 100% diesel-based systems—currently the most used solution for mini-grids – it offers lower operating costs, making electricity production more affordable. This is good news for rural communities, but it also opens new market perspectives for the private sector.

“What this study proves is that rural electrification with hybrid renewables mini-grids is not a vague, unrealistic option,” says Simon Rolland, secretary general of ARE. “The sector has matured to a point where it can easily attract investors and become self-reliable.”

This study presents a detailed overview of the technology and cost analysis from a life-cycle perspective, but most

importantly, it provides a complete socioeconomical outline of the main existing business models for hybrid mini-grid. All this is supported by practical case studies and leads to key recommendations on how to foster project sustainability and private sector participation.

One of the main recommendations is the need for strong social work and capacity building at every point of the project chain, in order to ensure the sustainability of the investment. Local stakeholder involvement from the project’s inception is also fundamental since mini-grids have a major impact on a community’s self-governance, education and economic development.

“Even the International Energy Agency foresees that mini-grid will be a mainstream solution in the fight against energy poverty,” says Rolland. “The introduction of renewable energy sources makes it even cheaper and more sustainable.” 

New Energy achieves threefold increase in ‘active area’ of SolarWindow™

Researchers developing the New Energy Technologies’ proprietary SolarWindow™, capable of generating electricity on seethru glass, have achieved a three-fold increase in the number of solar cells layered onto glass surfaces--a significant step towards maximizing power output.

The accomplishment is made possible when researchers spray see-thru and semitransparent electricity-generating coatings onto glass surfaces, in order to first create a working SolarWindow™ prototype.

Working with this small lab-scale prototype, researchers have achieved three times more cell occupancy (active area per square inch) over predecessor prototypes.

This increase in active area results from a new design.

“Generally speaking, the greater the number of see-thru solar cells we can arrange into contact on a given surface area, the greater the power output we can expect,” explains Mr. John A. Conklin, president and CEO of New Energy Technologies, Inc. “This three-fold increase in the number of solar cells on our SolarWindow™ translates into a greater active area, and directly supports our capacity to increase power output. This achievement marks yet another milestone in advancing our technology from prototype to commercial product, and follows several significant technical improvements announced in recent weeks and months.”

Recently, the company has achieved

important technical advances, including last month’s debut of New Energy’s largestever working SolarWindow™, measuring one-foot by one-foot square. Earlier this year, researchers developed special materials for use in SolarWindow™, which could lead to improved efficiency, lower production costs and enhanced future commercial manufacturability.

New Energy’s latest accomplishment increases the cell count and active area of SolarWindow™, both necessary to increased power output and the development of an aesthetically appealing see-through glass window capable of generating electricity.

There are nearly 5 million commercial buildings in America, according to the Energy Information Administration, and more than 80 million single detached homes. New Energy’s SolarWindow™ technology is under development for commercial application in such buildings.

Q-Cells achieves with 13.4% new efficiency world record for CIGS thin film solar module out of mass production

Q-Cells SE, one of the world’s leading photovoltaics companies, achieved a world efficiency record for mass-produced CIGS thin-film solar modules manufactured via monolithic integration. The Fraunhofer Institute for Solar Energy Systems (ISE) has confirmed an efficiency of 14.7 per cent (aperture area) for a Q-Cells Q.SMART UF solar module manufactured by Q-Cells’ 100 percent subsidiary Solibro GmbH. The record efficiency, measured in February 2011 by the renowned Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany confirmed a power output of 100.3 Watt peak (Wp) under standard test conditions. The Q-Cells Q.SMART UF solar module, with an area of 0,75 m², reaches a total area efficiency of 13.4 per cent. Moreover, with an aperture area of 0,684 m², the module’s aperture area efficiency is 14.7 per cent. Q-Cells CIGS thin-film technology now holds the world record for monolithically integrated photovoltaic modules based on the record efficiency table compiled by Progress in Photovoltaics.

‘In June 2010, Q-Cells achieved the previous efficiency world record of 13 per cent with the same type of CIGS solar module out of series production’, noted Gerhard Rauter, COO of Q-Cells. ‘With this new record—13.4 per cent—Q-Cells proves one more time its technological leadership in the photovoltaic sector.’ Q-Cells’ CIGS thin film modules are currently taking part

The fabrication of large ceramic sheet stock

The fabrication of large ceramic sheet stock Frank J. Ardezzone, FJA Industries, Inc., Santa Clara, California, USA

The need for tooling, rigid fixtures and handling equipment to service the semiconductor and photovoltaic industry has fostered the need for large sheet sizes. In the photovoltaic industry, we must process large numbers of photovoltaic cells (125 mm to 156 mm square) with gang tooling to meet production demands.

Large ceramic sheet materials can be used to produce the tools and fixtures required.

Keywords: Ceramic sheets 30 – Global Solar Technology – May 2011

I

n the 1960s, semiconductors were fabbed on one-inch wafers and any need for ceramic sheets was easily met. In 2011, we are contemplating 450 mm (17.7 inch) diameter wafers, which are larger than the readily available ceramic sheet often used by the industry. Herein lies the reason for the fabrication of large ceramic sheet stock.

The fabrication rules used for production of small sheets of ceramic do not extrapolate out for producing large sheets.

It is the general conclusion of most players in the industry that what was done for the fabrication of small ceramic sheet stock can be used to produce large thin sheet ceramic. Such is not the case from our findings. While sintering temperatures can be similar, the firing techniques are very different.

Let us first define what is generally available and what we call standard small sheet stock. Ceramic sheet material up to 4" (101.6 mm) square and up to .040” (1 mm) thick is available from 90% of the ceramic suppliers. In sizes up to 8" x 8" (314.9 x 314.9 mm) and thickness up to .040" (1 mm) it can be purchased from only about 10% of the ceramic suppliers. This size range represents the upper limit of what we call small and medium size ceramic sheet stock. The size beyond 8" x 8" up, we call large ceramic sheet. The thickness of the large sheet stock can range from .020" thick to .50” thick and that thickness is related to size. The current maximum available size is 22" x 17" x .040" to .50" thick, with larger sizes contemplated.

Why larger sheet sizes? The need for tooling, rigid fixtures and handling equipment to service the semiconductor and photovoltaic industry has fostered the need.

In the semiconductor industry we must handle, hold and process wafers that are currently 300 mm (11.881") in diameter; soon there will be 450 mm (17.717") diameter wafers. In the photovoltaic industry, we must process large numbers of photovoltaic cells (125 mm to 156 mm square) with gang tooling to meet production demands.

In addition, the machine industry that

Very large thin tooling for fabricating photovoltaic cells.

produces the tools to fabricate these parts needs to produce ever more precise equipment to meet fabrication requirements. The above needs can be filled by utilizing large ceramic sheet materials to produce the tools and fixtures required.

The use of structural ceramics techniques in conjunction with large pieces of thin ceramic sheets allows the designer a freedom that cannot be achieved using any other technique to produce the part.

Fabrication processes such as dry pressing, isostatic pressing or HIP injection molding and SLIP or JELL casting will not produce the size or quality needed to produce thin sheets. In simple terms, it is now possible to produce almost any shape that can be made in wood, plastic or metals using a ceramic sheet material in conjunction with structural ceramics assembly techniques. In many cases, the cost of the part will be less than conventional methods and the quality and performance will be superior.

Case study: Leveraging market and technology positions Analyst Buzz

Analyst Buzz Concentrated photovoltaics growing strongly through 2015 The Strategy Analytics GaAs and Compound Semiconductor Technologies (GaAs) service report, “CPV Technology Market Status Update and Future Prospects,” which was presented at Solartech World 2011, March 16-17, in Gwangju, Korea, predicted that CPV installed capacity will grow at a compound annual growth rate (CAGR) of 174% through 2015.

Solar energy installations have continued to grow strongly, with Strategy Analytics estimating that new global installations reached 16.3 GW in 2010.

Approaches utilizing crystalline silicon continue to be the primary technology,

followed by strong momentum behind a host of thin film technologies including cadmium telluride (CdTe) and copper indium gallium selenide (CIGS).

Concentrated PV (CPV) technology remains behind these other technologies.

Concentrated photovoltaic (CPV) technology, used for the production of solar energy, faces a number of challenges, not least because of potential limitations in deployable locations. Most effective in areas with direct sunlight, Strategy Analytics believes that CPV technology has the potential for strong growth.

“While potentially offering 100%

improvement in efficiencies compared to other solar technologies, CPV is only really effective where there is high direct normal solar irradiation,” says Asif Anwar at Strategy Analytics. “While this has limited early deployment, the benefits of CPV will translate into rapid growth in these locations.”

“In 2010, some significant projects came into play in the southwestern United States, the Middle-East, Africa and Australia,” says Eric Higham Director, GaAs service. “CPV installations will grow at a CAGR of 174% to account for just over 4% of global solar installations in 2015.” 

French solar funding in free-fall

are ambitious but nonetheless necessary for the long term remedy of PV price divergences in various national markets,” says Monssen-Wackerbeck.

As a result of the aforementioned changes in French solar funding, market pundits estimate that parts of solar projects currently in the planning phase may not yet be executed. According to the solar initiative, « Toche Pas à Mon Panneau Solaire » there were projects in the pipeline of 5.3 GW at the start of the halt in construction ordered by the Government in December. Some had already received building as well as net connection approval.

Other sources believe that the figure for projects in the planning phase is over three GW. “There are difficult times ahead for these projects” says Markus A.W. Hoehner, CEO of the Bonn-based Market Research and Consulting firm EuPD Research, “these systems were planned using a completely different calculation model and some of them will partly be recalculated.”

Nevertheless, market researchers at EuPD Research are not about to play the swan song for the French market “The industry should use this pressure to bring high systems prices in the country down to a competitive, European level,” adds Markus A.W. Hoehner. Figures from the current European PriceMonitor published

by EuPD Research show that, on average, the costs for a French PV system under 10 kW are about 4,400 Euro and peak at 6,000

Euro. Systems between 10 and 100 kW come with a price tag of 3,860 Euro.

However, market experts at EuPD Research see a downward trend in installed capacity as likely. “The market will consolidate in the next months, yet France still has considerable untapped potential in the private roof-top sector. Manufacturers that respond to this increased price pressure and, by highlighting their first rate quality and strong brand name, position themselves in the right segment will survive these tough changes,” MonssenWackerbeck says. 

As recently as December 2010, François Fillon, the French Prime Minister announced the introduction of a photovoltaic moratorium whereby no further PV systems were to be approved of.

This did not affect small PV systems up to 3 kW in size. This moratorium was followed by the February announcement of a strict limitation on yearly installed capacity to 500 MW. Today saw agreement on further reductions to solar funding.

The French Minister for the Environment, Nathalie Kosciuso-Morizet has announced that photovoltaic systems with a capacity of over 100 kW are now to receive a reduced remuneration of 12 €-Cent per kWh. The tariffs which come into effect today apply to all systems regardless of whether they are installed on a roof or open-space. Open-space systems are now faced with severe cutbacks to the tune of at least 57 percent compared to remuneration in September 2010. Rooftop systems are also to incur reductions of a staggering 70 percent.

Feed-in-Tariffs for small PV systems are, momentarily, to be reduced by 20 percent. Over the course of the year, quarterly declines of 10 percentage points will come into force. “This step will see the comparably high PV tariffs in France adjusted in line with those of neighbouring countries,” says Markus MonssenWackerbeck, head of energy & utilities at EuPD Research. “Such adjustments www.globalsolartechnology.com

PV book-to-bill in Q4’10 remains above parity

In Q4’10 (ending December 31, 2010), the PV book-to-bill posted a three-month average of 1.10, according to the PV bookto-bill analysis featured in the Solarbuzz® PV Equipment Quarterly report. Across the entire year, the 12-month average in 2010 reached 1.27 compared to 0.97 for 2009.

According to Finlay Colville, senior analyst at Solarbuzz, “The latest PV book-to-bill figures reflect the ongoing investments across both c-Si and thinfilm segments, which are driving strong capacity expansions planned for 2011.

Tier 1 c-Si manufacturers are expanding to reach vertically-integrated GW+ status on the back of still strong order books.

Conversely, investments into a-Si/uc-Si

and CIGS thin-film technologies represent the continued push by new entrants to find low-cost alternatives to First Solar’s exclusive challenge to c-Si dominance in the market today.”

Working closely with the PV equipment supply-chain, the Solarbuzz PV book-to-bill analysis maps out quarterly spending profiles by all PV manufacturers with the relevant bookings and revenues assigned to the appropriate process tool manufacturers.

The book-to-bill ratio compares the total amount of orders received to the total amount of product shipped and billed within a given period. It is the ratio of demand to supply in the equipment supply chain. A PV Book-to-Bill ratio of 1.10 for Q4’10 means that US$110 of orders was received by PV equipment suppliers for every US$100 of product shipped.

The consolidated PV book-tobill analysis yields an averaged figure based on industry-wide equipment investments across established and emerging technologies. However, tier 1 cell manufacturer trends can be a more appropriate leading indicator to assess the impact of production equipment used to meet end-market PV demand.

Colville says,“Tier 1 designated c-Si cell and thin-film panel producers satisfied 75% of PV demand during 2010. Equipment supply to this crucial midstream solar cell manufacturing segment highlights the portion of overall PV capacity expansion that is most likely to drive the level and timing of any panel oversupply during 2H’11.”

For the tier 1 segment, the PV Book-toBill ratio was higher at 1.39 during Q4’10, with a 12-month average of 1.26. Early indications are that this segment’s Book-

32 – Global Solar Technology – May 2011

to-Bill ratio will dip below parity during Q2’11. This would represent the first sign of capacity expansion slowdown by leading PV producers and the beginning of a downturn in revenues on offer to leading PV equipment suppliers through 2H’11 and 1H’12.

PV Book-to-Bill Updated Quarterly Photovoltaic capital equipment spending trends can now be tracked clearly by the PV book-to-bill, featured within the Solarbuzz PV Equipment Quarterly report. Added in November 2010, this analysis provides key performance indicators that track quarterly changes in the order books of the global equipment supply chain. The trends across the various Book-to-Bill metrics capture the overall health of PV manufacturing and offer a means of forecasting the size and timing of announced capacity expansion phases. The PV Book-to-Bill figures are updated quarterly, and include data relating to the preceding three-month period. In addition to releasing consolidated updates each quarter, detailed findings will be featured within forthcoming editions of the Solarbuzz PV Equipment Quarterly report, with the next release due out April 2011. Analysis will also be provided on an ad-hoc basis in support of Solarbuzz PV equipment reporting throughout the year, to better understand key developments and trends impacting strongly on the PV equipment supply chain. 

US solar energy industry experiences record-breaking growth in 2010

The U.S. solar energy industry had a banner year in 2010 with the industry’s total market value growing 67 percent from $3.6 billion in 2009 to $6.0 billion in 2010, according

to the U.S. Solar Market Insight™: Year-inReview 2010 released today by the Solar Energy Industries Association® (SEIA®) and GTM Research. Solar was a bright spot in the U.S. economy last year as the fastest growing energy sector, contrasting overall U.S. GDP growth of less than 3 percent.

In total, 878 megawatts (MW) of photovoltaic (PV) capacity and 78 MW of concentrating solar power (CSP) were installed in the U.S. in 2010, enough to power roughly 200,000 homes. In addition, more than 65,000 homes and businesses added solar water heating (SWH) or solar pool heating (SPH) systems.

The U.S. PV market made the most significant strides in 2010, more than doubling installation totals from 2009 according to the latest U.S. Solar Market Insight™ report. This expansion was driven by the Federal section 1603 Treasury program, completion of significant utilityscale projects, expansion of new state markets and declining technology costs.

The section 1603 Treasury program helped fourth-quarter installations surge to a record 359 MW and was critical in allowing the solar industry to employ more than 93,000 Americans in 2010. Originally set to expire at the end of 2010, the 1603 Treasury program was ultimately extended through 2011.

In addition, market diversification was a distinguishing characteristic of U.S. solar energy development in 2010. Sixteen states each installed more than 10 MW of PV in 2010, up from only four in 2007. The top 10 states for PV installation in 2010 were California, New Jersey, Nevada, Arizona, Colorado, Pennsylvania, New Mexico, Florida, North Carolina and Texas.

Cost declines were also an important factor in the 2010 solar expansion, as technology costs fell and the industry matured further, capitalizing on greater economies of scale and improved installation practices. In the residential and commercial-property segments, installed annual PV system cost declines of 8 percent and 11 percent respectively spurred record build-out.

“The U.S. PV market saw a breakthrough in 2010 and is emerging as a global demand center for both suppliers and project developers,” says Shayle Kann, managing director of Solar at GTM Research. “The U.S. Solar Market InsightTM: Year-inReview 2010 examines the conditions that led to the past year’s growth and pinpoints future demand, industry trends and market challenges for 2011 and beyond.”

“This report shows that solar energy is

now one of the fastest growing industries in the United States, creating new opportunities for both large and small businesses. Every day, Americans across the country are going to work at wellpaying, stable jobs at solar companies, from small installers all the way up to Fortune 500 companies,” says Rhone Resch, SEIA president and CEO. “This remarkable growth puts the solar industry’s goal of powering 2 million homes annually by 2015 within reach. Achieving such amazing growth during the economic downturn shows that smart polices combined with American ingenuity adds up to a great return on investment for the public.

The bottom line is that the solar energy industry is creating tens of thousands of new American jobs each year.”

Along with analysis of the U.S. PV market, U.S. Solar Market Insight™: Yearin-Review 2010 provides visibility into the CSP and solar heating and cooling markets.

The 75 MW Martin CSP plant installed in Florida is the largest to come online in nearly 20 years and foreshadows a pipeline of more than 9 GW of CSP projects under development. In addition, for the first time in 2010, the federal government approved permits for CSP plants on public land.

Meanwhile, the solar heating and cooling markets grew in 2010. The top five states for solar water heating installations in 2010 were California, Hawaii, Arizona, Florida and Puerto Rico, while the top five for solar pool heating were Florida, California, Arizona, New York, and Illinois.

Fluctuating natural gas and heating oil prices will determine the future of these markets. 

Opportunities for smart coatings in the solar panel industry

In a just-published report, industry analyst firm NanoMarkets claims that smart coatings offer solar panel makers ways to increase efficiency, lower costs and create higher value-added products. Since these are the three main factors determining success in the photovoltaics (PV) industry, NanoMarkets believes that sales of smart coatings to the PV sector, which are negligible now, will reach $504 million in 2016, growing to $847 million in 2018.

Self-cleaning coatings deposited on PV panels promise both higher panel performance and lower maintenance costs.

Self-cleaning glass is already available from major glass manufacturers, so no great leaps in technology are required to deploy it in the PV space. By 2016, self-cleaning smart coatings sold into the PV sector will

www.globalsolartechnology.com

reach more than $150 million in revenues.

Electrochromic and similar on-demand tinting smart coatings will generate $222 million from sales to the PV sector in 2016. NanoMarkets believes that by then lucrative opportunities will have arrived in this sector through the melding of BIPV glass panels with electrochromic smart windows. NanoMarkets also foresees electrochromic PV windows that incorporate OLED technology, so that they can serve as lights after dark.

Thermochromic smart coatings are also expected to play a role in PV. These can be used to turn panels “off ” under extreme heat conditions that could permanently damage them. Some PV technologies— notably CdTe PV—are sensitive to heat and permanent degradation is possible if the panels are operated at too high a temperature.

“Smart Coatings in Photovoltaics” examines the role of self-cleaning, self-healing, electrochromic and thermochromic coatings in the photovoltaics space over the next eight years. It includes an assessment of where the main opportunities will appear and when and includes a detailed eight-year forecast of smart coating usage in the PV space, broken out by volume and value.

This report will be essential reading to marketing and business development executives at all coatings and materials firms selling into the PV space as well as product managers in the PV industry. 

2010 record year for PV installations in US

The US photovoltaic industry has experienced significant growth during the past few years, despite difficulties in the housing and construction sectors. Many factors, which contributed to this growth includes a drastic module prices decline in 2009, sustained federal support from the Section 1603 Treasury Cash Grant in Lieu of Investment Tax Credit program, and increasing state-level targets for solar power. The country experienced a record year for PV installations in 2010, with cumulative grid-tied capacity estimated to reach 2.2 GW mark by installing around 700 MW in 2010.

Photovoltaic is the most dominant segment in terms of budget allocation for FY 2011. This segment is followed by concentrated solar power plants. The photovoltaic industry has been allocated above 50% of the solar energy budget owing to its economic viability and potentials for being a replacement of conventional

energy sources. During FY 2001-FY 2011, 48% of the government’s solar energy technology budget was allocated for near term projects (7 years) and Mid-term (3-7 years) projects both accounted for 26% of the budget allocation.

According to a new research report available from Reasearch and Markets, the US federal government continued its support and substantially increased solar energy technology budget. To propel the growth rate of PV installations in all sectors (utility, non residential, and residential), the states have formulated various incentives and grants. Presently, some of the states and the Federal government are moving away from simple rebate program and performance based incentives (PBI’s) to effective cost based incentives schemes.

At the state level, California sustained its top position in annual PV capacity installations during 2009, with 7% yearon-year growth. Besides, California, New Jersey, Florida, Arizona, and Colorado were some prominent states, where gridconnected PV systems installations were concentrated. Around 80% of the gridconnected installed capacity was located in these five states and around 92% in the top ten states.

The report, “US Photovoltaic Market Analysis,” focuses on the growing marketplace for the PV industry at the national and state level and analyzes the current market trends along with future growth prospects. It evaluates all prominent market segments including residential, utilities, and non-residential.

The report provides statistics information, state level analysis, PV cost benefit trends, module wise cost forecasts, and utility scale solar facilities to help clients identify the factors critical for their successful market penetration. 

German PV Market: Federal Network Agency reports figures for PV installed capacity 2010

The Federal Network Agency published the Decemeber figures for newly installed PV capacity today. Although there was no end of year rally, figures for Decemeber still amounted to 1,073 MWp. A comparison of the figures for the whole year shows that Decemeber was in fact the second stongest month. Thus, newly installed capacity for PV in Germany amounts to 7.25 GWp. This is equivalent to a year-on-year growth of 91 percent and making 2010 another recordbreaking year for the German PV industry.

important PV market. Newly installed capacity totalled 7.25 GW and an impresseive 242,893 systems were installed in 2010 reaffirming Germany as the key sales market worldwide. “These figures are not a surprise,” comments Markus A. W. Hoehner, CEO of the Bonn-based market research and consulting firm EuPD Research. “Newly installed capacity is for the most part in line with our forecast,” confirms Hoehner. The Bonn market researche institute revised its forecast in June from 5.5 GW to 7.2 GW. Installed capacity according to system size: Small systems stabile, large system segment grows Systems between 10 and 30 kWp made up 26 percent of newly installed capacity making them the greatest contributor to growth in 2010. Particlular dynamic was observed in the mid to large system segment between 100 and 500 kWp. This segment has, in comparison to the previous year enjoyed growth of an impressive 174 percent.

Regional installed capacity: Bavaria remains number one nationwide Bavaria once again spearheaded growth in 2010 with an installed capactity of 2,379 MWP (+33 percent) clearly placing them ahead of all other states. The state of Baden-Wuerttemberg came in second and North Rhine-Westphalia third.

Outlook for 2011: Germany will continue to enjoy growth although more moderate “The facts speak for continued growth in the German market,” says Markus Lohr, analyst at EuPD Research. „Growth in most regions is, compared to that of previous years, overproportional.“Only some regions are showing symptoms of saturation,“ comments Lohr. Although business was slow at the start of the year, the market is set to clearly pull forward in the coming months, as soon as prices have stabilized.

Futhermore, the market researchers estimate that development in the German market is likely to be somewhat dependent on the poltical decisions pending in Italy.

An additional effect is expected to stem from mid-year degression. As a peak in installed capacity expected in June will not be included in the calucaltions for the halfyear degression, it is not to be assumed that this half-year degression will thwart the market significantly. Thus, EuPD Research anticaptes further but more moderate growth in the German market for the year 2011. 

34 – Global Solar Technology – May 2011

Europe continues to dominate solar market in 2011

Despite brewing trouble for the solar industry in the region, Europe in 2011 will continue to account for the lion’s share of photovoltaic (PV) installations in the world, claiming 68.6 percent of the global total, according to the latest IHS iSuppli research.

Comprising nine of the world’s 15 major solar markets, European PV installations this year will amount to 14.3 gigawatts (GW), more than two-thirds of the global level of about 20.9 GW. Europe will be home to the world’s two largest solar markets—Germany, with an estimated 7.1 GW; and Italy, with 4.1 GW—as well as seven other important PV territories including, in descending order, France, Belgium, the United Kingdom, the Czech Republic, Spain, Greece and Bulgaria.

In comparison, the United States—the third largest solar market worldwide—is projected to see 2.1 GW of PV installations in 2011, IHS iSuppli research indicates.

Notwithstanding Europe’s majority hold on global solar installations, its 68.6 share of market in 2011 will be a step down from 80.0 percent last year, when European installations reached 13.8 GW. Growth for the region also will decelerate this year, declining to 4.3 percent, down from a notable 146 percent expansion in 2010. In particular, bad news and uncertainty from specific European markets will serve to dampen overall PV prospects in 2011 for the continent.

The good news vs. the bad While Europe is continuing its dominance, the region faces challenges in one of its key countries: Italy.

“Italy had been expected to be the star performer of the European market in 2011,” said Henning Wicht, senior director and principal analyst for PV systems at IHS. “However, on March 3, the Italian government changed its solar policies, implementing changes in its tariffs that make the PV market in the country less attractive to investors starting in June.

While the Italian government is expected to fundamentally continue to support PV, installations in the country will decelerate in 2011 compared to earlier expectations— although they won’t stall.”

Installations in Italy in 2011 will amount to 4.1 GW, up 14.6 percent from 3.6GW in 2010.

Compared to Italy, the PV market situation is weak in Germany. Investors are still hesitating and awaiting lower system

prices. System prices must reach 2.0 to 2.2 euros per watt to spur installations of large systems.

Slow demand in Germany already caused inventory at wholesalers to increase, a phenomenon that is now slowing down orders.

Although Germany is currently at the forefront of the global PV trade, the market here is expected to peak before four years are out, Wicht added. By 2015, German solar installations will stand at 5 GW, less than the country’s 2010 level.

In addition to the uncertainty facing the German PV sector, measures are under way to reduce the business proposition for solar investors in Spain, France and the Czech Republic, IHS iSuppli analysis shows.

In the case of Spain, the government is set to reduce the funding of existing solar power parks by approximately 30 percent.

In early March, France implemented a new scheme supporting new installations of 500 megawatts (MW) per year. In addition, earlier accorded projects will be built. Estimates for France call for 1.3 GW to be installed in 2011. And in the Czech Republic, where state support for ground-mounted plants will end in March, PV installations for the year will contract severely, falling to 350 MW from 1.3 GW in 2010.

Looking ahead, the highest-growth PV markets in Europe will be Belgium, Bulgaria, Spain and the United Kingdom.

By 2015, however, the United States will become the world’s single largest solar market, overtaking Germany, which will drop to second place after years of being at the pinnacle.

competitive.

The report found that the components with the most significant impact on Lower Levelized Energy Cost (LCOE) were the Solar Field, followed by Operations & Maintenance. From this, the report can conclude that LCOE reduction of 5% is possible if O&M costs are reduced by 20%.

Similarly, the same reduction in the power block, TES, or indirect cost will only reduce LCOE by 2% according to the new research report from CSP Today.

The industry should therefore focus on reducing solar field costs, i.e. collectors, mirrors, absorbers, hydraulic actuators, and HTF piping. The report finds that the same holds for O&M costs, which can significantly reduce the running cost per kWh produced.
