Solar project should be designed for a life of 25 years. What quality parameters should mounting structures adhere to sustain over this period? First and foremost any given solar project starts with an optimum design. With increased cost pressures, it is critical to consider the longevity of the project as a whole. Our design capabilities assure longer project life. The next critical aspect is the kind of material chosen considering the geographical conditions of the solar plant.
Our customized mounting structures are manufactured from cold rolled Zn-Al/Zn coated steel and offers high corrosion resistance, aptly suitable for extreme weather conditions. The alloy coated steel ensures longer life and its high strength provides better load carrying capacity with longer spans. This is extremely critical for solar fields which are often subject to extreme weather conditions and directly exposed to harsh environments.

companies. Given that the majority of a solar project’s capital expenditure is EPC costs (approximately 70%-90%), the cornerstone of any bankable solar project is a properly negotiated EPC Contract. As such, developers must offer lenders and investment partners bankable EPC Contracts that centralize the responsibility for meeting many of the perceived challenges associated with a big solar project and make the risk profile of the entire solar project more attractive to such potential partners. This article identifies the five fundamental risks facing any project developer in an EPC Contract and lays out an easy to use checklist of legal and commercial tools to mitigate them and to ensure the developer is able to present debt lenders and equity investors with the most bankable EPC Contract possible one that is the most likely to deliver a well-performing solar project on time and on budget.
Bankability A “bankable” EPC Contract is an agreement between the EPC contractor and the developer that establishes a risk allocation profile for the construction of a project that satisfies the requirements of lender or equity provider. As discussed below, lenders and equity investors are primarily concerned with whether or not the EPC contractor can claim additional costs or extensions of time under the EPC Contract. Additionally, they are concerned with the EPC Contractor’s ability to perform its obligations under the EPC Contract and the security provided by the EPC contractor or its parent company to secure its performance. These elements should be top of mind for every developer because, the further the terms of the EPC Contract are from the requirements of the lenders or investors, the greater amount of equity support the developer will have to provide for its project. In assessing the bankability of an EPC Contract, lenders and investors will look at a range of factors and assess a contract as a whole. Generally speaking they will require the following: � Fixed completion price; � Restrictions on the ability of the EPC contractor to claim extensions of time and additional cost; Output and performance guarantees;
grounds on which the EPC contractor can ask for additional compensation to a very narrow, well-defined subset of excusable events and a very clear change order process for addressing such events. In addition, the parties may negotiate whether certain events like force majeure or change in law, which are commonly
EPC Contracts) that place the EPC contractor “on the hook” for performance liquidated damages if the EPC contractor fails to meet the performance guarantees. The end result is that, upon completion of the project, the EPC contractor is responsible to deliver a facility that actually meets all preagreed performance criteria by a specified date. A few of the developer’s tools for mitigating performance risk are: � Minimum Guaranteed Capacity: The EPC contractor should incur delay liquidated damages in the event the project fails to meet the minimum guaranteed capacity (and which should be a condition to substantial completion) by a date certain. The minimum guaranteed capacity should be set at the level at which the project must operate to support the developer’s capacity requirements under the Power Purchase Agreement.

to review invoices before being obligated to make payment. � Right to Dispute in Good Faith: The EPC Contract should allow for the developer to dispute those invoices or items in an invoice that it believes are inaccurate or not due and owing. In order for both parties to keep the project moving, it makes sense for the developer to be obligated to make full payment for those undisputed items in the invoice, but to withhold payment on the disputed portions until the parties can agree on such items or such items are resolved via the EPC Contract’s dispute resolution mechanism.

The construction of a large-scale solar plant requires a myriad of permits and approvals from governmental authorities and regulatory bodies, including land use and zoning, building permits, federal and state authorizations, and environmental permits.

While lenders and investors are concerned with liquidated damages under a Power Purchase Agreement to a certain extent, their primary concern with a delay in construction is that it does not result in the Power Purchase Agreement being terminated and the project losing its source of revenue entirely.

A more protective approach is to establish a right for the developer to declare a default and terminate the EPC Contract prior to the outside date if the EPC contractor could reasonably be expected to miss an outside date. In this second approach, the developer does not have to wait for the actual Power Purchase Agreement outside date to be missed and for the fallout to come from the

system before the substantial completion is declared in order to ensure that everything is squared away before the EPC contractor can leave the site. Additionally, the developer can hedge completion risk by not relying solely on the utility providing test power before the witness test and instead penciling in as many tests as possible before the witness test in order to guarantee a smooth process on the day of testing. � Third Party Audit: In order to get comfortable with the electrical, and technical details of the system, lenders and investors will want to hire a third-party to conduct an audit after the system achieves mechanical completion. This third-party engineer will compile audit results in a non-conformance report from which the developer can direct the EPC contractor to make any corrections. � Test Before the Witness Test: A lot can be tested before the witness test. In fact, inverter commissioning and transformer commissioning will require some test power. There are examples of certain utilities who have recently stopped providing test power before a witness test for grid-related safety reasons. If this is the case, it is important that the EPC contractor have access to a back-up generator and a load bank at its disposal. The EPC contractor should coordinate the engineer of record and the inverter technician to be on-site the day of inspections and the day of witness testing. This is a simple way to ensure that any questions or necessary fixes can be performed immediately. � Detailed Testing: Different off-takers will require different tests. The developer should make sure all necessary testing is properly identified as a condition for substantial completion in the EPC Contract, including: PV module flash test analyses; String I-V Curve Tests; Megger tests; Continuity tests; thermal scans of main components; DAS and monitoring system tests; reliability tests, etc. � Review

Industry Insights Is your PV Remote Monitoring/SCADA System Functional? Have you invested in a best in class Solar PV SCADA and now unable to monitor your PV Plant? You are not alone! There are several Solar PV Plant owners repenting their decision on the choice of PV Monitoring system/SCADA. At Avi Solar Energy, our Analytics & Monitoring team studied and analysed over 1GW of Solar PV plants across India. Here is the summary of our analysis: For a Solar Plant Developer, getting the Inverter up and pumping power to the grid has been the focus when a new plant is built. SCADA is the last item in punch list, because even if it is not functional, the generation is still ON! Its only after couple of years after the plant is commissioned, when the O&M team reports issues at the site, plant owner realizes that monitoring is important to figure out the performance of the plant. Here are some of the major issues with SCADA / Remote Monitoring systems that we have experienced in field

6. No String Level Monitoring � Data collection is limited to Inverter monitoring only. String level faults cannot be detected. The good news is that, there are retrofit solutions available which can replenish your existing SCADA and bring the plant data to your remote monitoring centre. IoT being the buzz word today, there are several options to get the data from your plant to the cloud in a cost-effective manner. There are several IoT platforms which can monitor data from PV plants. EagleSun SCADATM is one such platform exclusively developed for Solar PV Plants.

Industry Insights GLOBAL LANDSCAPE OF RENEWABLE ENERGY FINANCE 2015/2016 The landscape of renewable energy finance has evolved rapidly. Since 2012, renewable power capacity installations have exceeded non-renewables by a rising margin, representing about 60% of all new power-generating capacity added worldwide in 2016 (IRENA, 2017a). Investment reached a comparable milestone in 2015, when renewable power technologies for the first time attracted more finance than non-renewable power technologies (Buchner et al., 2017), a trend that has continued subsequently. This report analyses the renewable energy finance landscape. It outlines key trends globally in 2013-2016, regionally and by technology, examines the differing roles and approaches of private and public finance, highlights the important role of risk mitigation instruments, and provides an outlook for renewable energy finance in 2018 and beyond.
EMERGING TRENDS Global overview � Global annual investment in renewable energy rose steadily in 2013-2015, peaking at USD 330 billion in 2015 before falling to USD 263 billion in 2016. � While annual investment declined in 2016, capacity additions in the same year were up from 2015. This is partially due to declining costs and partially to the time lag between financial closure (i.e., the time of investment) and the completion of construction, after which an installation becomes operational. � Cost declines for key technologies have influenced finance flows. Lower solar and wind power costs, in particular, reduced the total value of renewable energy investment in 2015 and 2016, as each dollar of investment financed more capacity than in previous years.
Investment by region � The East Asia-Pacific region was the dominant

While these auctions were held on Friday, earlier last week, the reverse auction for 2,000 MW capacity haf discovered tariff of Rs 2.44 per unit, which matched the lowest ever rate that was found in May 2017 for Rajasthan’s Bhadla projects. Before the latest two auctions, an impending threat of hefty 70% safeguard duties on solar cells and panels had pushed up the tariffs to as high as Rs 3.54 per unit, giving credence to the analysts’ fears that the lower rates would be unsustainable. According

“The biggest tender was floated in Spain. We brought out a single tender of 10,000 MW which would be opened in July. Now we will bring out a bid of one lakh MW which would also include solar manufacturing and storage,” he told the event, according to The Economic Times. One lakh represents 100,000 units.

Company Feature Saatvik’s mission is to lead the global transition to renewable energy in India Saatvik is a part of a bigger business group with diversified business activities with major interests in edible oil and oleo chemicals. The group has multiple manufacturing facilities for extraction and refining of edible oil, refining non-edible oil and manufacturing of soap. The group has over 25 years of experience serving the highest quality products to FMCG giants in India. With the interests of the group lying in renewable energy, it forayed into solar panel manufacturing, hence setting up Saatvik Green Energy, in 2016.
What the Company Does: Saatvik Green Energy is a new age solar technology company, involved in the manufacturing of high quality solar modules. The current product portfolio includes solar modules of all ranges starting from 40Wp up to 350Wp in both 4BB and 5BB. Saatvik uses both poly-crystalline and mono-crystalline cells to assemble these solar modules, coupled with multiple rounds of testing during and after the manufacturing process, ensuring the highest quality product for its esteemed customers. All module ranges have been certified to highest global quality standards.
Strategy Vision Statement: At Saatvik Green Energy, we actively support the global effort to energise the world through alternate and greener sources of energy, by manufacturing and distributing world class solar photovoltaic modules, globally. We seek to attain and establish our position as the most reputed, customer centric, significant solar module provider to Solar Industry.
Mission Statement: Saatvik’s mission is to lead the global transition to renewable energy in India. Our part to play in that transition is to deliver cost effective utility scale solar energy solutions to customers and governments through the set of cohesive company principles. These principles are the foundation of everything we do at Saatvik:
w w w . s o l a r q u a r t e r . c o m
Integrity. Safety. Innovation. Sustainability. Teamwork. Strategy. Respect.
Business Goals & Objectives: As a business, we continuously seek to improve our products and services, to deliver the best quality to our clients. Given the vast amount of options in the industry, only a satisfied client leads to repeat purchases. We want to become a consumer centric company, by not only providing high quality products, but also research and innovate to make solar industry in India integrated and greener.
Business Strategy: Saatvik wants to be a one stop solution for solar technology and services, and it is moving towards the ambitious goal, step by step. 2018 will see Saatvik expand from 200MW to 500MW annually, as it has made a mark as a rising star in solar module manufacturing. At present, when we view the industry holistically, there is an oversupply of solar companies throughout the value supply chain. Two valuables that are missing is quality and innovation. Rather than integrating vertically, we have strategically partnered with regional engineering companies to provide services to our customers.
Products & Services The current product portfolio includes solar modules of all ranges starting from 40Wp up to 350Wp in both 4BB and 5BB. Saatvik uses both poly-crystalline and mono-crystalline cells to assemble these solar modules, coupled with multiple rounds of testing during and after the manufacturing process, ensuring the highest quality product for its esteemed customers. All module ranges have been certified to highest global quality standards, through a global certification body, TUV Rheinland.
Business Competitiveness Price competitiveness is the foremost issue faced by solar equipment manufacturers. As a fact, India still imports 88-90% of its total solar panel requirement. This gives
a very limited breathing space to plethora of solar PV manufacturers in India. The inability to compete with imported equipment in terms of price, ultimately leads to fierce competition within the Indian manufacturers for limited number of avenues using Indian made solar PV equipment. Quality Policy Of The Company: ISO ratings, standards & specifications etc. Not only does Saatvik comply with ISO, but it has also implemented SAP H4 HANA which helps in automating a lot of manual processes, for superior records and quality implementation. If your people and processes are sorted, precision comes naturally, and we are a very quality conscious company, hence precision plays a very important role. To assist our people and processes, we have all necessary quality control/inspection equipment both in-line and in the laboratory, to ensure precision in our production for highest quality products.
Team & Management Saatvik, being a young company, managed by people in 20’s and early 30’s, has very dynamical horizontal organizational structure. Saatvik believes in smaller team and greater efficiency. This way, every person working for Saatvik feels a sense of ownership.
Customers & Projects Saatvik has been able to make a good portfolio of customers already, including India’s leading IPPs and solar developers, apart from regional and national EPC companies. Saatvik solar modules have been successfully installed at various government buildings, government utilities, railway stations, hotels and universities, such as Delhi Jal Board, DMRC, Western Railways, Ambala Airforce Station etc. Saatvik’s constant strive towards quality, delivery and commitment has made its products lucrative to many clients, and will continue to do so in future.

Company Feature N-type or P-type cell: What is the world mulling for? A solar photovoltaic (PV) cell comes with variety of technology. This means that for a layman or a novice in the
Figure 1: Average stabilized efficiency values of Si solar cell (Source: ITRPV 2018)
field, it becomes quite puzzling to select the right type of technology. For instance, the basic technology that could be found in today’s market is p type & n type solar cell. While their purpose remains the same i.e. to capture sun’s irradiance and turn it into energy, it’s their manufacturing process which differentiates them. Anyone with knowledge on history of solar cell would know that the first solar cell was fabricated at Bell labs in 1954 which was of n-type mono-crystalline. Until 1980s, with the application of solar cells being mainly on satellites, the p-type solar cell had shown less degradation to exposure of cosmic rays. Thus for decades, the industry had kept continuous focus on p-type PV cell development. However with the changing market trends and the continued research on n-type solar cell in previous decade, its ability to outperform the currently in use p-type solar cell cannot be ignored. With the currently available diverse technology of solar cells and the predictions of advancement in efficiency of (almost) all these solar cell (both p-type and n-type) (Figure 1), it is important for us to understand what would be market inclined towards. Additionally, this blog would also give its readers an insight on technical advantages and disadvantages of both n-type and p-type solar cells. From figure 1 above it is evident that both p & n-type solar cell shall experience a jump in their efficiency. However from
Figure 2: Basic cell structure of p-type cell (on left) compared to n-type solar cell (on right)
an investor/ end user’s perspective, it is important that you know the basics of these types of cells. As evident from figure 2 below, the p-type solar cell has p-type semiconductor at its base and vice versa (for n-type solar cell). This difference (in base) arises only when the doping on wafer (both multi and mono) is performed (Figure 3). Necessary to create a semiconductor junction which inducts the flow of current, the wafer is either doped with phosphorus (leading to n-type wafer) or boron (leading to p-type wafer). Let us now understand the advantages of both these technology. The first advantage of p-type cell is economics of the scale, due to the current and previous market trend which had demanded for p-type solar cell, they have an

upper hand on economics of scale in manufacturing.
Figure 4: World market share for different wafer types (Source: ITRPV)
This is because the entire value chain right from sand to solar cell is optimized as per p-type solar cell. Its next advantage is its cost competiveness compared to its opponent. In the current market scenario, initial cost may become a determining factor which gives p-type an upper hand. Coming to the advantages of n-type cell, firstly they are more efficient compared to their counterpart. This means that one can expect more power output and hence more revenue from the same area. Secondly they are susceptible to various degradations (explained later) experienced by a p-type solar cell. This means that we can have an increased lifetime of module made from such kind of cells. Additionally they are also less sensitive to impurities (compared to p-type cell). Thirdly levelized cost of electricity (LCOE) (a ratio of total cost incurred to total energy generated over plant’s lifetime) can be moderately significant (sometimes even plant’s return of investment (ROI)) when compared to p-type cell. As we had mentioned in introduction of this blog, p-type cell are currently dominant in the market. With the introduction of highly efficient cell technology like PERC for commercial use, the solar market is expected to bolster. The PERC alike other cell technology comes in both p & n-type. However there are still lots of challenges which are needed to be addressed and the major being Light Induced Degradation (LID) and Light enhanced Temperature Induced Degradation (LeTID) for p-type cells. LID & LeTID are known to have cause significant reduction in power output in PERC module. A lot of efforts are necessary to
increase the few practical remedies possible for (partially) eliminating LID & LeTID. N-type PERC cell however are known to be LID & LeTID free. This means that a steady power output can be expected out of such modules. As predicted by ITRPV, the market share of n-type mono solar cells shall rise to around 30% (Figure 4). We however believe that its market share would rise to around 40% by 2028 given its advantages. We at Waaree Energies have understood such technology trend and have capability of producing both p-type and n-type cell based solar module. Our modules are backed up by the stringent quality certificates we have received from various national and international certifying agency.

Tech Insights To Store Or Not To Store Is the emerging market for energy storage a standalone “new tech” development or is it part of a bigger movement in which different interconnecting technologies, business models, and regulations are revolutionizing the way we generate, transport, sell, buy, and consume energy? At Capgemini, we believe it’s the latter. To gain insight, the Energy & Utility team of Capgemini Netherlands composed a research topic in cooperation with Erasmus University Rotterdam around “Emerging Business Models in homes with Energy Storage.” The University assigned this topic to graduate student Michael Zigo and the Capgemini Energy & Utility team hosted and guided the assignment. The research sought to provide a power storage simulation under a variable time-of-use pricing scenario. The outcome of this simulation shows typical household production and consumption with and without the use of power storage. In addition, the simulations provide net energy consumption cost benefits of using power storage. For the research, an optimization function to simulate household energy storage use was developed. The analysis was based on real data from 300 households with a 15-minute realtime pricing scheme located in a microgrid community in the Netherlands. The microgrid featured a number of wind turbines and half of the households were equipped with solar panels. In addition, no power storage was implemented in the microgrid to store power. The use of home energy storage capacity in a microgrid community mitigated the “duck curve” effect: a graph of power production over the course of the day, showing the timing imbalance between declining renewable power production combined with peak demand after sunset. Despite the fact that the “duck curve effect” is mitigated in the mid-afternoon hours, steep ramps and drops were observed. Such steep fluctuations are caused by a “herd effect,” when all households in a microgrid trigger discharging or charging their energy storage unit at the same time. The typical household in the community was able to achieve a cost benefit of €14, a 28% decrease from the original monthly energy bill of €50 per month. We simulated this case with a 7KW storage unit; however, if a more expensive 10KW solution were to be implemented, the energy bill could be reduced by €18. The calculation is based on the fundamental principle of net metering, according to which the same price of energy is used in the simulation when consumed from and supplied to the grid. Variables such as charging speed, capacity of storage, and discharge speed to a grid directly influence the behavior of an energy storage solution. Optimal values should be developed per each use case. “The typical household in the community was able to achieve a cost benefit of €14, a 28% decrease from the original monthly energy bill of €50 per month”.

Tech Insights LONGi Solar has enough technology preparation to keep PERC competitiveness for the next 3-5 years The challenges posed by the new policy released on May 31 by Chinese government cannot stop PV enterprises from pursuing high-efficiency technologies. The first half of 2018 witnessed a particularly booming industry. HJT has accelerated its industrialization, TOPcon has been introduced into mass production, MWT has gradually become a force that cannot be ignored, N-PERT is accumulating strength… Facing intense competition from various efficient technologies, Dr. Li Hua, Vice President of LONGi Solar, firmly believes that PERC will remain the most competitive and cost-effective cell technology in the next five years, and LONGi Solar’s technology reserves absolutely can support the efficiency improvement of PERC technology in the next 3-5 years. Like most technologies, PERC technology did not originate in China, but has blossomed in China, and brought too many surprises to the industry over the past year. At the initial stage of development, many industry experts claimed that PERC cell technology had its own bottleneck, and it would be ideal to have a mass production efficiency of 21%. However, contrary to the original forecast, PERC lab efficiency is now close to 24%. The history of efficiency improvement of LONGi Solar, the backbone of PERC

proves that PERC technology has strong vitality and broad application prospects. “PERC cell only needs to add Al2O3/SiNx rear coating and laser opening mask techniques on the basis of the traditional cell techniques. Compared with other highefficiency cells and technologies, PERC cell technology is less difficult, and the investment cost of equipment is lower. In recent years, the cost of PERC cell has dropped quickly, and has been more and more close to that of conventional cells. At present, other high-efficiency cells do not have such a cost performance,” said Tong Hongbo, Cell Research Center, LONGi Solar. Based on its technical advantages of silicon wafer, LONGi Solar has continuously optimized cell techniques to achieve a maximum cell conversion efficiency of nearly 24%, to which the material selection of silicon wafer and the design of cell technique are particularly crucial. “The core of monocrystalline PERC cell is passivation. The impurities in silicon wafer and the surface defects of silicon wafer have a negative effect on the performance of cell. Passivation is to ensure the efficiency of the cell by reducing the impact
has successfully solved the problem of yield. At present, LONGi Solar’s yield of PERC cell is more than 97%, which is close to that of conventional cells. Manufacturing equipment plays an important role in the development of PERC cell technology. At present, automation has become the standard configuration of new PERC production lines. The rear passivation technology route of key PERC equipment is clear, the mass production equipment and techniques are gradually mature. “At the initial stage of PERC cell technology, restricted by the equipment support for mass production, the cell conversion efficiency only remained at lab efficiency.” Zhao Xufei, Cell Research Center, LONGi Solar, introduced, “based on the demand for cell performance improvement, LONGi Solar has worked with equipment suppliers to transform and improve the equipment structure and performance. The equipment performance is becoming more and more satisfactory, enhancing the competitiveness of PERC cell technology continuously.

Tech Insights RENEWABLE ENERGY AUCTIONS - CASES FROM SUB-SAHARAN AFRICA Renewable energy has come to dominate new investment in the global power sector. The year 2015 was crucial, marking not only the largest annual addition of new renewable power (155 gigawatts [GW]) and the sector’s highest level yet of capital investment (USD 312.2 billion), but also the lowest-ever prices for long-term renewable power contracts. It was also the year that renewable energy investment levels in low- and medium-income countries surpassed those of high-income countries for the first time (FS-UNEP, 2017; IEA and IRENA, 2017).
Figure 1 Utility-scale (> 5 MW) solar PV: Average bidding tariff (USD/MWh), 2010 17
In 2016, the trend in record installed capacities continued, with 161 GW added. Yet investments fell by 23% to USD 241.6 billion, and developed economies regained the lead in renewables development. Nevertheless, the latest data show that installed capacity for renewables has now overtaken coal and that renewables remain the fastest growing source of electricity generation (IEA, 2016). Prices for renewable energy installations continued to fall in 2016, a trend that was also evident in the outcomes of renewable energy auctions. In February 2016, Peru’s renewable energy auction saw solar photovoltaic (PV) prices of USD 48 per megawatt-hour (MWh); in March that record was broken by prices of USD 45/MWh coming out of Mexico’s auction. Chile’s auction in August produced a price of USD 37.8/MWh, and in September, in Mexico’s second auction, the average price came in at USD 32/MWh. Dubai’s auction in June was the first in which the USD 30/ MWh barrier was broken, and Abu Dhabi announced prices bid in at USD 24.2/MWh for its anticipated 1.17 GW installation, following an auction in September. Figure 1 illustrates recent price developments over time for solar PV auctions (average prices), differentiated by country. Significantly, prices do not always fully incorporate the total costs associated with a project and/or do not necessarily fully reflect a project’s entire (required) revenue stream. For example, in some cases projects are required to cover costs associated with system integration, while in other cases these costs are socialised amongst end users. In other examples, the indicated prices reflect a maximum payable price to be received during specific times of the day, season or year, with lower prices applicable during the remainder of the period. As these price-driving differences exist, a comparison of auction prices (as in the graph below) can only be the starting point for a deeper comparative assessment, which would account for the relevant price-driving differences, accordingly. The global trend in renewable energy investment – both in terms of increasing volumes as well as falling prices – is in large part driven by favourable governmental support mechanisms, such as feed-in tariffs (FiTs) and auctions. Auctions are interchangeably referred to as competitive tenders or bids for long-term contracts between independent power projects (IPPs) and offtakers (typically the national or local utility). These are gaining global relevance, as more than 67 countries – most of them developing – are using these competitive procurement mechanisms to contract renewable power. While in absolute terms there are still more countries using FiTs as their renewable energy support mechanism (80+), the overall growth trend suggests that more countries will use auctions than FiTs very soon (REN21, 2016).
Based on IRENA (2017). Running effective renewable energy auctions requires good planning, procurement, and contracting capacity, and can involve significant transaction costs. These costs are, however, usually offset by the benefits of lower tariffs. Some auctions face the risk of “low balling” in bid prices, which might result in delays in reaching financial close (FC) and construction. While these are important to consider, a well designed programme can effectively mitigate these risks (Eberhard and Naude, 2016a; IRENA and CEM, 2015). A recent article has touched upon the value of auctions as a mechanism for price determination and policy support for renewables in the sub-Saharan African context (Lucas, del Rio and Sokona, 2017).
Based on IRENA (2017).
This report investigates the design of renewable energy auction programmes in sub-Saharan Africa (SSA), focusing specifically on three groundbreaking countries in their pursuit of new renewable power: South Africa, Uganda and Zambia. Guiding the analysis is a framework developed by IRENA and the Clean Energy Ministerial (CEM) suggests four broad categories to investigate (IRENA and CEM, 2015): � Auction demand: This is the choice of the volume auctioned and the way it is shared among different technologies and project sizes. This includes specific demand bands, determining the auctioned volume, periodicity and long-term commitments, and demand side responsibilities.
selection criteria, clearing mechanism and marginal bids, and payment to the auction winner. � Sellers’ and buyers’ liabilities and obligations:3 These are the characteristics of the product being auctioned, along with certain responsibilities and obligations spelled out in the auction documents. These include commitment to contract signing, contract schedule, remuneration profile and financial risks, the nature of quantity liabilities, the settlement rules and underperformance penalties, delay and underbuilding penalties, assigned liabilities for transmission delays, and risk mitigation and credit enhancement.
� Q u a l i f i c a t i o n requirements: These determine which suppliers are eligible to participate in the auction, as well as the conditions with which they must comply and the documentation that they must provide prior to the bidding/evaluation stage. This includes reputation requirements, technological requirements, production site selection and documentation, securing grid access, and measures to ensure socio-economic development (SED). � Winner selection process: This involves the bidding and clearing rules as well as the process of awarding contracts to the winners. This includes bidding procedure, requirements of minimal competition, winner Credits-

Tech Insights Solar Power System Installation and Operation: Best Practices in the Industry In most cases, solar power systems are simpler to install than other energy generation equipment. However, this does not mean you can get careless when deploying a rooftop PV system, since things can go wrong if the design and installation procedure are not performed correctly. Of course, the opposite also applies: with smart decisions and best practices, you can maximise the benefits obtained from solar power.
Optimise Your Solar System Design to Avoid Problems Later The underlying principle of solar power systems is simple: photovoltaic modules produce DC power from sunlight, and the inverter converts it to AC power usable by your home appliances. However, it is also important to consider site conditions in actual projects. In the case of rooftop PV systems, the following aspects should be analysed carefully: � Rooftop condition: Does it have the structural strength to support a solar array? Are some areas of the roof better suited for solar panels? Does the roof have a steep slope that complicates work?
be suitable for use with solar panels, considering they are also exposed to the weather. Wiring should be optimally sized: there are power losses if the conductors are too small, but oversized conductors represent an unnecessary expense.
routine cleaning. Maintenance personnel should avoid stepping on the modules, although this is not an issue if you work with professionals, and maintenance is under the provider’s responsibility if you deploy solar power through a Power Purchase Agreement (PPA). The cleaning procedure should also be performed avoiding damage to the surface of modules, since it causes a performance degradation over time; for this reason, cleaning modules with a high-pressure water jet is not recommended.
Solar Array Monitoring and Maintenance Although a solar power system can operate without monitoring, many benefits are achieved by tracking performance. For example, if a sudden drop in generation cannot be attributed to the weather or the passing seasons, a performance issue is very likely. Problems can range from solar array areas covered by leaves to loose connections or malfunctioning modules, but the first indication is a performance drop indicated by the monitoring system. Many modern inverters come with built-in monitoring capabilities, and they often include a mobile application.
Conclusion To summarise, you will get the best results with a solar power system if it is custom-designed for your property, while using high-quality equipment and keeping in mind that some system components last less than solar modules. The combination of a monitoring system and adequate maintenance ensures that issues are prevented, which is much cheaper than solving problems after they occur. Author: Mr. Cameron Quin

� Presence of shadows: The output of solar panels is drastically reduced under shadows, so they must be avoided whenever possible. If shadows cannot be avoided completely, the solar array layout must minimise their impact. � Ease of maintenance: Solar panels should not be packed too tightly, to provide space for maintenance personnel. For example, if three rows of solar modules are installed in a tight arrangement, the middle one will be more difficult to service- maintenance personnel should not walk on solar panels!

� Interconnection: Depending on where it is installed on your property, a solar power system may be more difficult to connect. Consider that long runs of wire are expensive and they also cause a voltage drop, similar to how long water pipes cause a drastic pressure loss. You can tell you are working with qualified solar designers if they pay close attention to all the factors above. Avoid generic offers where the same solar system configuration is offered for all properties.

Purchasing High-Quality Equipment
Fault diagnosis Wide input range
Quality is often associated with a higher price, but it would be more correct to say that quality is an investment; you pay more upfront to get even greater benefits in the long run. In solar power systems, the main benefits of using top grade equipment are more productivity and solid warranties. Of course, you should also perform a background check of equipment suppliers. You will want to work with companies that will be around in the future if warranty claims are required. Solar panels typically come with two warranties: a 10-year warranty against manufacturing defects, and a 25-year energy generation warranty - if production drops below a value specified by the manufacturer, you can get the faulty panel replaced. Note that the term of these warranties may change, but these are the typical values in the industry. Unlike solar panels, inverters are normally rated for only 10 years, which means you can expect two replacements over the 25-year life of panels. Also consider that solar panels are built for direct exposure to the weather, while many inverters are not - they should be installed in a protected area where they will be easy to service, and eventually be replaced.
