ET is working with Industries where one day failure means huge Loss, so ET Transformers are designed for zero failure and are seasoned with industrial load pattern and easily offer extended warranty for any commercial coverage. The backbone of the company is the robust research and development section. Electric arc furnaces (EAF), ladle furnaces (LF), ferroalloys smelting furnaces and high-current rectifiers need a specific design to supply the necessary power at a low voltage level and must be designed to resist the high secondary currents, which are normally regulated by an on-load tap changer / star-delta off load switch, either directly on the high-voltage winding or via an intermediate booster located

within the same tank or in separate tank. EAF transformers are rigidly designed to withstand repeated shortcircuit conditions and high thermal stress, and to be protected against operational over voltages resulting from the arc processes. ET preferred to supply with in-built reactor for long arc stability. Thus makes the lifetime of the transformer is also extended. Rectifier transformers are combined with a diode or Thyristor rectifier. Thyristor rectifiers require voltage regulation with a no-load tap changer, if any. ET is the highest number of supplier for converter transformers. Those are used for induction furnace operation, large drive application, static voltage compensation (SVC) and static frequency change (SFC). Converter transformers are suitable for 6 / 12 / 18 / 24 / 36 Pulse. Such transformers normally have an additional winding as a filter to take out harmonics. Different vector groups and phase shifts are possible. In ET transformer, the special consideration incorporated while designing are the harmonics, frequent short-circuit, Rapid and large load fluctuations, Operational over-voltages due to frequent switching along with LV bushing arrangement to limit

struct u r a l heating. Furnace and Converter Duty Transformer are constructed with Single / Double / Triple Deck and with extended Delta on Primary or Secondary side to achieve desired phase shift.

SoLayTec Launches its Second Generation InPassion ALD tool for PERC Cells

tomic layer deposition (ALD) equipment specialist SoLayTec, a subsidiary of Amtech Systems, has launched its second generation InPassion ALD tool for PERC cells.

24 SmartEnergy Sept 2016

According to the company, combined with the newest direct PECVD, it can annually produce up to 130MW, including the integrated anneal process.

The new product has been hailed by SoLayTec as “a highly cost-effective solution” capex-wise and has published customer data to back this claim up. The main improvement of the second gen www.supersmartenergy.com

customer this gives a wider opportunity to use our ALD system, besides PERC applications also for other high efficiency cell concepts like: n-PERT, IBC, PERL and the latest Topcon approach,” he added.

eration model is cited as the uptime and net throughput of the machine. The company also claimed that TMA usage and efficiency gains edge the new product above competitors. “For PERC integration the Al2O3 ALD machine only, is not the complete solution. A customer also needs a PECVD capping machine for covering the Al2O3 layer. So far a customer needed at least six direct PECVD tubes to meet the ALD output of 3600wph. Since the 10th SNEC exhibition in Shanghai, [Amtech subsidiary] Tempress introduced the SPECTRUM PECVD which has at least the same net capacity as the InPassion ALD. So now capex wise we have a highly cost effective solution available for our customers”, said Roger Görtzen, co-founder of SoLayTec and director of marketing and sales.

The evaluation showed that this efficiency was achieved by “optimising the process flow and integrating a post-deposition anneal into the SiNx capping process,” as stated by a Hanwha Q CELLS research paper. The technical paper also found that the SoLayTec product demonstrated improved passivation quality resulting in the Voc gain remaining constant during light and elevated temperature induced degradation measurements. “At SoLayTec we are very proud of this result, confirming our efficiency benefits at an important tier one cell manufacturer”, said Görtzen, in a statement. “For our

Tempress and SoLayTec are both part of the Industrial Affiliation programme at research institute imec. At Intersolar, imec and its partners presented the latest results of their large area n-type IBC cells of 22.8%. Imec already proved that ALD Al2O3 was a good passivation material for p+ emitters, but in this work the ALD from SoLayTec plays a significant role to passivate also the n+ emitter, the company explained. In the past, the standard passivation method was always by using Wet thermal SiOx, but now also for IBC concepts the gain is +0.3% by using the ALD Al2O3layer. SoLayTec recently performed a PERC integration for a customer in Asia. This ramp-up of a standard multi cell line into mono PERC reached a daily capacity of 50,000 PERC solar cells, with a stable cell efficiency of 20.6% ■

During Intersolar Europe 2016, leading PV cell manufacturer Hanwha Q CELLS published results of using the InPassion ALD compared with their MW-PECVD system. A comparison of the two technologies found that the SoLayTec product offered a 0.150.25% better efficiency for multi-cSi PERC compared to the MW-PECVD AIO×.

View Point

he International Energy Agency (IEA) has identified the development of renewable energy sources as a key element to mitigate climate change. At the same time, it has projected India to be the second-largest contributor to the increase in global energy demand to 2035. India hence faces a significant challenge to ensure its energy security by diversifying its power generation mix.

Policy Framework India was the first country in the world to have a dedicated ministry for Renewable Energy. It was established as the Ministry of Non-Conventional Energy Sources in 1992 (re-christened as Ministry of New & Renewable Energy in 2006). The Jawaharlal Nehru National Solar Mission (JNNSM) announced in 2010 under India’s National Action Plan on Climate Change, setup targets, through a systematic approach and structured framework, linking them with the nation’s 5

year plan, and establishing sector based Renewable Purchase Obligations (RPO). The objective of the National Solar Mission is to establish India as a global leader in solar energy, by creating the policy conditions for its diffusion across the country as quickly as possible.

Advantage India India is endowed with abundant solar energy, which is capable of producing 5,000 trillion kilowatts of clean energy. We are blessed with around 300 sunny days in a year and solar insolation of 4-7 kWh per Sq. m per day. Many States in India have recognized and identified solar energy potential and other are lined up to meet their growing energy needs with clean and everlasting solar energy. In near future Solar energy will have a huge role to play in meeting India’s energy demand.

R A L SO

Rooftop Solar PV One of the immediate aims of the National Solar Mission is to focus on setting up an enabling environment for solar technology penetration in the country both at centralized and decentralized level. With large scale infrastructure development in India now extending to towns and villages, the demand for electricity has subsequently been increasing over the years. As a result, distribution utilities are unable to support peak demand in all areas, with frequent power outages. Rooftop Solar PV system is one of the best solutions to cater to this demand. The systems can be grid-connected / interactive or off-grid / standalone systems, depending on the application of the load, and availability of grid power Rooftop

solar power is being aggressively explored by commercial, industrial, and residential consumers for ii On-site generation of power at reasonable rate ii Productively utilizing unused rooftop space Rooftop space is often left un-utilized in many establishments; installing a solar plant on the roof is a great way to derive additional value from your premises Depending on the tariff regime, solar power may prove to be cheaper than even grid power for some consumers and definitely more economic than diesel power for all, and offers the added advantage of fixing the cost of power for the next 25 years.

Cost Benefit Analysis Though the initial investment in setting up a rooftop solar plant may be high (to the tune of Rs. 80,000 per kW, depending on the plant size), the savings realized over a period of time help in offsetting the costs involved. It also helps in establishing a fixed cost or zero cost (with estimated escalation) towards power consumption over a period of 25 years (typical life cycle of solar PV plant, with warranties)

Incentives & Subsidies Financial incentives by Government for rooftop solar power plants (industrial & commercial) include ii Accelerated Depreciation ii 10 year tax holiday Thereby aiding in reducing the payback period, and the burden of taxes on the asset owner. However, budget constraints & approval for upfront investment and lack of capital subsidies in the above mentioned sectors may result in delay in decision making

Current Initiatives from Government of India Amalgamation of Ministries The ministries for Power, Coal and Renewable Energy have been brought under a common leadership, with Shri Piyush Goyal heading all three portfolios This has helped a lot in establishing effective co-ordination among the three sectors, in terms of

100% electrification

ii A payment security mechanism to cover the risk of default by state utilities/discoms

24x7 - Power for All (24x7 PFA) is a Joint Initiative of Government of India (GoI) and State Governments with the objective to provide 24x7 power available to all households, industry, commercial businesses, public needs, any other electricity consuming entity and adequate power to agriculture farm holdings by FY 19. MNRE is heading this initiative wherein off-grid solar PV for rural areas and grid interactive rooftop solar is expected to play a key role.

Make in India Further, the PM of India’s Make in India program mentions the following incentives ii Exemption from excise duties and concession on import duties on components and equipment required to set up a solar plant ii Guaranteed market through solar power purchase obligation for states ii Generation based incentive schemes for small solar projects connected to a grid below 33KV ii Reduced wheeling charges as compared to those for conventional energy ii Special incentives for exports

ii Loans at concessional rates for off-grid applications

Solar Energy Corporation of India (SECI) ii SECI was set up in 2011, under MNRE as a not-for-profit company as an implementation and facilitation institution dedicated to Solar Energy sector. ii Mandate of SECI allows wide ranging activities to be undertaken with an overall view to facilitate implementation of JNNSM and achieving the targets set therein. ii The Corporation has the objective of developing Solar Technologies and ensuring inclusive solar power development throughout India.

International Funding ii The World Bank recently announced it plans to provide more than $1 billion (£0.7bn) to support India’s solar initiatives. ii Some of the projects under preparation include rooftop solar, bringing innovative solar and hybrid technologies to market and transmission lines for solarrich states.

ii India plans to install at least 400MW of rooftop solar and develop a $200 million (£150m) shared infrastructure for a solar parks project under a public-private partnership model. ii The investment pledged by the bank would be its largest financing of solar for any country in the world to date.

Future as it appears ii Immense scope & opportunity for investments and projects in solar PV sector with the rising demand for electrification. ii Lack of clarity on how the likely additional costs as input taxes in the upcoming Goods and Services Tax (GST) regime would be allowed as a pass-through by the regulators. ii With more number of players, new entrepreneurs entering to the Solar EPC business, the prices will be more competitive, and overall cost of setting up a solar project might come down. However, this may also lead to tariffs going below Rs. 4 / kWh ■

Heating Systems. We believe no market is as big as Indian market, there is immense potential for

solar products in rural market, where our products meets to the mere necessity. Our Recent Products launched in the markets are Sun on Wall (Unique Street Lighting system with integrated batteries inside the fixture) refer image on the side and 999 Solar Home lighting system.

Q Solar wall mount streetlight

.Tell us more about your manufacturing facility? Amongst the different products that you manufacture, which are the products that are likely to contribute the most towards the future growth of the company? Our Manufacturing facility is

ď&#x192;&#x153; www.supersmartenergy.com

located at three places, two are in Pune and one is located at my home town Kasegaon near Kolhapur, manufacturing more than 25 Solar Products . We are very well equipped with advanced machinery and testing tools, which keeps us a step ahead in the market to provide world class products. Every product we manufacture is of highest standard and stands the test of time as all this products are designed as per the requirements of the customers. In recent times products such as Domestic Water Pumping Systems, Unique Home Lighting Systems and Solar Rooftop Grid Connected Systems are the ones which we presume would be the ladder of growth for our company.

.What is the product quality policy that you follow? How do you ensure that products of utmost quality reach the customers? Madhuri Solar has entered in to Solar Industry with a Vision “ Energy For Every One “ and mission to become the most admired and respected name in the field of Solar energy applications in Indian and International markets. Right from Sourcing the highest grade of raw materials till the final product, our Products undergo rigorous quality check adhering to the standards at each and every step. The maturity of our process ensures delivery on time, with minimum defects and agreed service levels via our diverse and wide range of dealer networks. We follow 5S process, where every employee is responsible for the products at every stage, incase of any faulty products which doesn’t pass QC they are retained and re assembled with through quality checks and this has helped us in reducing manufacturing defects to a large extent.

.What goes into innovating or developing a new product? How do incorporate the feedbacks from your custom-

ers? Could you elaborate with an example? As said Necessity is mother of all inventions, our innovations follow market needs with time. One needs to be optimistic about the concept, understand the needs of the target customer, and cost of the new product. Innovations are possible due to application engineering, for which one has to constantly study the requirements of the market. Successful product is the one which enters the market at right time, at right cost .It's a cycle which every product has to go through, one wrong turn and entire product fails. Before getting a new product to the market, we at Madhuri Solar test the product to see if it satisfy all the needs of the final user. We send out sample to different class of customers to test it. Once it is tested, valuable feedback from customers are taken into considerations and suitable changes in products are made. Solar wall mount streetlight is one of our newly launched product. Previously customers had problem that battery in streetlight required maintenance. Since streetlight is mounted outdoor they required battery box to cover battery & locking system as there were chances of battery getting stolen. Installation of streetlight with 5 meters pole required insertion of ½ meter pole below ground & 4.5 meters above ground, for this we also required civil structure for making pole stand strong straight. Due to this system became costly, bulky for transport, installation & use. Taking this feedback from the customers we innovated AC LED LUMINARY which has in built no maintenance Li-ion battery. Also instead of 5 meter pole you can mount our wall mount streetlight within few minutes directly on any of your wall simply by drilling few holes & tightening screws. Space requirement, civil structure, battery box, cables, locking system cost is completely eliminated. However, if required you

can mount this compact system on pole also. Solar Panels are kept separate & we have not combined panel & luminary together because we wanted our customer to rotate luminary as per their requirement at whichever position they wanted. But Solar panels has to be placed only in direction where it can get maximum sunlight. Our next step is to combine panel to make it ALL-INONE system.

.As a Solar equipment manufacturer, what according to you are the difficulties or challenges for the Industry? What support does the industry need to make it globally competitive? Solar Equipment manufacturers today face difficulties to match the imported solar products price,specially Chinese ones. Low Quality of Raw material is largely used by solar manufacturers to sustain in the market to match the prices with the imported products. This is ruining the quality of products and has harmed the solar industry to a large extend.

.As a rooftop player, what are the core competencies that differentiate Madhuri Solar from the competitors? How do you ensure quality and reliability of solar rooftop projects? Years of experience in Solar Industry has led us to develop our own strengths. We have developed our own standard operating procedures for Solar Rooftop Installations comprising of all the necessary quality products and installations way beyond the standards demand. Life of the system should go on for 25 years, devices used in such installations should meet the purpose. As a technology partners we are associated with Fronius as Sales and service Partners for Solar Inverters, Leoni for Solar DC cables, Lighting and Earthing protections with Dehn.

We have adequate skilled and trained manpower to carry out service and maintenance thus ensuring minimum downtime. We believe its an installers responsibility to meet generation performance for which perfect installation along with the best in class quality products, service and timelines of service calls are of highest essential need.

.With the government targeting 40GW from rooftop solar, what are the opportunities that you are looking at in solar rooftop space? What according to you are the key challenges for the sector that need to be addressed? 40 GW is a ambitious and respectable target set by Govt of India. Solar rooftop segment has ocean of opportunities, as majority of the states have initiated net metering policy for rooftops and we can sense huge demand in commercial, industrial and residential sector. Concept of net metering is new for the Indian markets, but implementing the process and getting a net metering systems from Discoms is still a task . Immense resistance and delay in implementing net metering from states or Discoms has stalled solar rooftop segments though Captive consumers have taken leap and have commenced installations. Various companies or individuals have jumped into this sector without any prior knowledge of Solar, which has resulted in incor-

32 SmartEnergy Sept 2016

rect installations with lower quality of the products causing lower performance of the plant. This is one of the key challenges that the industry is facing today, though MNRE has started Channel partner programs to educate and get the authentication in roof top segment. Large competition is seen today in this segment, one has to give the best quality with the best per Wp prices.

.How does Madhuri Solar integrate CSR with sustainable development? We carry out different CSR activities, some of them is Educating school kids on Solar training kits from LEX solar . We also provide Solar Home lighting, Solar Lanterns, Solar Water Pumping Systems to people living in tribal areas. We are also working with one of the NGOs on solar DC micro Grid systems , in areas where there is still no electricity. We strongly believe to be a light in darkness for those of who still leave in the dark.

.Shed some light on the partnership with German companies INPRO Solar and LEX solar? What are the products from these companies that you market in India? We constantly innovate our mix by introducing unique products such as Solar Education Kits, Solar Toys and Corporate Gifting Items through our exclusive channel partnership with German companies like INPRO Solar and LEX Solar. We are committed to innovating in the field of solar energy so that our consumers can get high quality products and our chil-

he Indian power sector scenario has improved continuously. Renewable energy sources such as solar, biomass, geothermal, hydroelectric and wind power generation have emerged as potential. Renewable energy sources are generally unlimited in availability. Solar power generation has emerged as one of the most rapidly growing renewable sources of electricity. Solar energy, which is abundant in nature and has no recurring fuel cost, is considered to be the best and non-polluting. Solar energy is obtained through the use of Solar cells. The Solar cells convert sunlight into electrical energy, based on the principle of photovoltaic effect. The electricity so obtained can directly be used to charge the batteries used for various appliances. To get the maximum efficiency from solar Modules, In India modules should be oriented south facing to receive maximum sunlight. The Modules produce more power at low temperature and full sun & tracking the Sun increases the amount of power from an array. The Solar panels are generally installed in such a way that they can receive maximum direct

Energy Storage

Microcell TM Carbon Foam (MCF) Batteries for Photovoltaic Application

echnology improvement and infrastructure development has to go hand in hand for the betterment of a nation’s economy. Both have to complement each other in order to strive for a better tomorrow. Today we have been hearing and reading how fast the solar energy harvesting is growing or any renewable energy. But when it comes to energy storage we still rely on same old lead acid batteries. It is been more than 160 years since the advent of lead acid batteries and it remains as the safest and the proven chemistry with a limitation in life. When it comes to lithium ion battery, we are limited in terms of cost and chemistry. Firefly Microcell TM Carbon Foam (MCF) batteries offers a revolutionary new pathway to tap into the vast new global market for energy storage. Validated by demanding customers and third party testing, this product is commercially available worldwide. Its price and performance overcome the current barriers and offer a practical pathway to accelerate the explosive growth experienced by the global energy storage market. MCF Batteries offer 2-3 times the life and lower life cycle cost compared to current Deep Cycle Lead Acid batteries. It is compatible with legacy battery management systems and can be recycled within the existing infrastructure.

36 SmartEnergy Sept 2016

Firefly Batteries offers equal or superior performance compared to new and emerging battery technologies such as Li-Ion, Lead Carbon and Ultra-cap batteries at a fraction of the cost. History of Firefly MCF batteries Firefly’s revolutionary battery technology was born in the Research and Development laboratory of Caterpillar, Inc., a worldrenowned manufacturer of heavy equipment. Caterpillar has long been a consumer of batteries for its many heavy equipment products. These equipment, by their very nature, put a severe strain on the batteries. Hot and cold extreme temperatures, severe vibrations and prolonged periods of disuse are standard operating conditions for these heavy equipment. Caterpillar found that normal lead-acid batteries could not withstand this strain and with a new corpo-

rate focus on improving the performance and longevity of the batteries turned over this issue to their R&D arm who came up with Microcell Carbon Foam as the solution. This technology has been patented and allows for the exploitation of existing lead-acid chemistry to a much higher level and compete head-on with other advanced battery technologies, including the Lithium batteries. These batteries offer much higher efficiency and cycle life which in turn brings down the cost of ownership to a large degree. Lead Acid Battery Failure Modes To make an advance in battery technology that goes beyond evolutionary engineering Improvements requires a paradigm shift to new materials and/ or new processes. Some of the common failure modes found in the lead acid batteries are shown below.

Why carbon foam technology? The signal advantage of Firefly’s Microcell™ technology is that it fundamentally changes the distribution of active materials within the lead acid cell due to its unique architecture. Overall, the Firefly composite foam electrode structure results in are distribution of electrolyte from the smaller separator reservoir to the pores of the foam plate(s), resulting in a 70/30 to 30/70% reversal, respectively, relative to conventional lead acid products. Each foam plate contains hundreds or thousands of spherical microcells (depending on the foam pore diameters). This leads to enhanced active material utilization levels, because each microcell has its full complement of sponge lead or lead dioxide and sulfuric acid electrolyte. Liquid diffusion distances are reduced from the traditional levels of millimetres over linear paths (the conventional “2D” diffusion mechanism found in the lead metal grid-based classic lead acid battery architecture) to

the level of micron diffusion path lengths in the three-dimensional space within the discrete microcells that, collectively comprise a totally new type of electrode structure (what Firefly calls a “3D” electrode). Such a structure results in much higher power and energy delivery and rapid recharge capabilities relative to conventional lead acid products. Dramatic Cycle Improvements

Life

A full discharge of today’s lead acid battery causes extra strain, and each cycle robs the battery of a small amount of capacity. In leadacid batteries, deeper discharges convert larger amounts of charged active-material into lead sulfate. Lead sulfate has a significantly larger volume (about 37% more) than the charged material, and this volume change stresses the electrode structures. This expansion induces mechanical forces that deform the grid, and ultimately

result in the lead grid “disappearing” into the paste. The resulting expansion and deformation of the plates also causes active material to separate from the electrodes with a commensurate loss of performance. Additionally, over time, sulfate crystals can grow together, resulting in large lead sulfate crystals that are difficult or impossible to convert back into the charged state. This wear-down characteristic also applies to other battery

Sept 2016 SmartEnergy

Energy Storage chemistries in varying degrees. To prevent the battery from being stressed through repetitive deep discharge, a larger lead acid battery and shallower discharge is typically recommended. Depending on the depth of discharge and operating temperature, the sealed lead-acid battery provides 200 to 300 discharge/charge cycles. Short cycle life also results from grid corrosion of the positive electrode, which undergoes extensive oxidative stress during extended recharge conditions. These changes are exacerbated at higher operating temperatures. In contrast, Firefly’s Microcell™ composite plate technology provides a design which fully accommodates the volume changes of

the active material during charge and recharge. Within each Firefly plate is contained a full complement of active materials, electrolyte, and volume which will allow complete discharge without causing physical stress on the plate itself. This results in an electrode plate which does not undergo volume change during deep discharges. Firefly’s electrode material is not reactive in the chemistry and so does not corrode. This is in part due to a natural stability of the base material, but is also due to the formation process used which maximizes exposure of the most chemically resistive surfaces and minimizes exposure of chemically less-stable surfaces. The growth of large sulfate

38 SmartEnergy Sept 2016

crystals is also restricted, resulting in a low incidence of crystals which are too large to recharge. The strong resistance of Firefly’s electrode material to corrosion also severely reduces the deleterious effects of long recharges. Because of the removal of grid corrosion as a life-limiting factor, the Firefly approach offers significant improvements over conventional lead-acid technologies in both float and deep-cycle applications. Cycling in irregular applications such as partial-state-ofcharge (PSOC) regimes used in hybrid vehicles and photovoltaic energy storage are also well suited to 3D technology. This is because the conditions of partial or heavy sulfation of the negative plate – a process that can render present-generation lead acid products unrecoverable – are easily reversed in 3D products, even after long periods of storage. Sulfation reversal is achieved because the nature of the lead sulfate deposits in 3D cells is fundamentally different from those in traditional lead acid cells. In the latter, lead sulfate is deposited on the surfaces of the plates in dense layers of relatively large crystals, somewhat remote from the lead grid members. Because the sponge lead active material in a 3D cell is deposited on the walls of the foam’s many small pores in thin layers, and the surface characteristics of the foam result in relatively low current densities, the lead sulfate depos-

its are comprised of small, porous crystal structures (on the order of 3-10 microns, much smaller than in commercial products) that are easily dissolved on the subsequent recharge. Moreover, these very small crystal sizes grow only slowly over time. A final factor that facilitates recharge is the proximity of the carbon-graphite foam (as well as residual sponge lead) that can act as efficient current-carrying paths during recharge for the small, local deposits of lead sulfate crystals. This resistance to the effects of sulfation make Firefly 3D batteries ideal for seasonal applications where devices and their associated batteries (electric lawn mowers, boats, RVs, motorcycles, etc.) may go unused for months on end, often in a partially or fully discharged state. Conventional batteries are difficult or impossible to recover from these conditions, and are often replaced far short of their potential life span. With 3D products this problem is greatly reduced. “The” Photovoltaic energy storage battery: Firefly has designed a 4V 450 Ah battery for energy storage application which overcomes the limitation of grid corrosion, active material shedding and sulfation. With traditional maintenance free batteries basic building blocks are either 2V or 6V cells. 2V cells presents a its disadvantage with respect to handling and manufacturing where as in 6V, the cell

Figure 2. 4v 450 Ah MCF battery

 www.supersmartenergy.com

in the middle always end up with unequal charging and heating up. Firefly has found a right balance where the batteries contain 2 cells of 2V each. These batteries use 3D microcell carbon foam technology which counteracts the sulphation of plates. The MicrocellTM carbon foam uses a porous conductive schema where about 95% pores are interconnected. The surface area of the carbon foam is about 2000 times than that of prismatic plates. These 4V 450 batteries can be charged with a current of about 0.3C10 (120 A) to 0.5C10 (200 A) with a constant voltage for better results under partial state of charge (PSOC).Under partial state of charge MCF batteries have a unparalleled charge efficiency of >98%. 3D Performance Summary In summary, then, the 3D cell

architecture results in numerous attributes: ii Instantaneous Power (2 hours and faster run-time rates) ii Fast recharge capability ii Continuous power through discharge process ii Recovery to full capacity after off-season storage ii Excellent cold temperature capacity utilization ii High temperature resiliency ii Recovery to full capacity after discharge The remarkable attributes of the composite foam negative electrode noted above make certain applications possible or more favourable, as well as improving many lead acid “weak points” such as sulfation recovery and activematerial utilization limitations. At slow discharge rates, modest

weight and volume improvements over existing lead-acid products (typically 15-20%) are achievable as well. For faster discharge rate applications (like HEV, Starting or UPS applications), the weight and volume saving can approach 50-75% or more ■

STALWARTS OF THE INDIAN SOLAR SECTOR AN INSIGHT ON THE 5 COMPANIES CONTRIBUTING TO THE GROWTH OF SOLAR SECTOR IN INDIA

India is set to become the 4th largest solar market globally in 2016 behind only to China, USA and Japan thanks to the government’s thrust on significantly enhancing the installed solar capacity to 100 GW by 2022. India has witnessed record capacity addition of around 3 GW in FY16, 1 GW in Q1FY17 and bids of around 6 GW awarded over the last 6 months or so. The sector is witnessing increased participation from large overseas investors as well as developers. Decline in solar PV project costs and entry of various players has led to significant increase in competition which has led to significant decline in solar tariffs as visible from the trends in the completed bids over the last 9-12 months. Weighted average tariff for the bids which came up during FY16 stood at Rs.5.26/unit may decline further to around Rs.4.5-4.8/unit in FY17, with increased competitive intensity and decline in costs. The ability to manage cost efficiently, secure longer tenure and cheaper debt are the key factors which will have bearing on the bids, returns and viability of the projects. Here Anisha Ganguli speaks to the respective heads of the five solar companies ACME Cleantech Solutions, Hitachi Hi-Rel, Trina Solar, Vikram Solar and First Solar and profiles these companies in depth, detailing their ambitions, goals, challenges faced and their success stories.

VIKRAM SOLAR

Delivering Comprehensive Energy Solutions Globally With an international presence in 4 continents, Vikram Solar is an active contributor in shaping the solar revolution. Under the dynamic and visionary leadership of Gyanesh Chaudhary, Managing Director and CEO, Vikram Solar the company is set to expand beyond boundaries.

ich legacy and extensive manufacturing experience of the Vikram Group has imbued Vikram Solar to offer quality solutions contributing to global solar revolution since 2006. Vikram Solar was born with the idea that solar energy is not just an option anymore; it is a necessity to protect our environment and satisfy the growing energy consumption rate. With this core value, Vikram Solar manufactures high quality solar modules and contributes to the global energy shift. The journey of this Indian company gone global has been very interesting and inspiring. Vikram Solar was established in 2006. Within just three years, in 2009 they made their first mark in international solar industry and established an office in Germany- Vikram Solar GmbH. In 2010, Vikram Solar stepped in international EPC business to deliver comprehensive energy solutions globally. Year 2011 saw them installing a total of 3 MW solar generation capacities in India. In 2013 they contributed to the solarisation of the world’s first fully solarized airport Cochin International Airport, Kerala, India. They also installed utility scale 40 MW power plants in Rajasthan that year. In 2014 they offered India its very first floating solar panel in West Bengal, introducing the idea of utilizing water bodies to harvest solar energy in wake of ever-decreasing land availability. In 2015, they success-

fully completed India’s largest airport rooftop solar installation at Netaji Subhash Chandra Bose International Airport, Kolkata and in the same year, they reached 0.5 GW annual PV module production capacities and announced a 2 GW by FY 2020 manufacturing capacity goal. Being awarded the National Excellence Awards from MNRE in 2016 as a domestic solar module manufacturer is a testimony of their hard work. Vikram Solar manufactures quality solar PV modules ranging from 10 Wp to 345 Wp. Their standard product range is divided in three tiers- 72 Poly cell module, 60 Poly cell modules, 36/18 Poly cell module. Their manufacturing capacity stands at 0.5 GW today and they are also a comprehensive solar EPC solutions provider, with an installed capacity of over 130 MW in India. Vikram Solar is a firm believer of quality research. They have invested more than INR 100 million in Research & Development and product certifications. Through their research, they saw some distinctions in preferences and requirements for solar modules around the world. Hence they decided to cater all of these preferences, thus developing diverse products to drive both volume and margin. To cater to the highly demanding Indian solar energy sector, Vikram Solar has already initiated the expansion of their second

Cover Story

The 2 MW Rooftop Solar Plant at Netaji Subhash Chandra Bose International Airport, Kolkata manufacturing facility in Falta, West Bengal. Their new facility is being equipped with latest equipment and machinery to enhance the efficiency in manufacturing modules. This will allow them to reach their 1 GW annual manufacturing capacity goal in a compressed time frame. Presently Vikram Group has presence in 32 countries and has entered into technology and infrastructure collaborations with Fraunhofer ISE in Germany, Meyer Berger, Centrotherm and they are also a part of HDPV Alliance, in USA. These collaborations will bring innovations in module manufacturing through research and knowledge sharing. Gyanesh Chaudhary asserts that it is not just the quality that has made them an industry leader but their responsible and dynamic team members. The team maintains precision in project completion timelines and execution guidelines. They are stickler about meeting industry standard protocols. Plus, he also attribute their success to state of art modern manufacturing facilities. Stringent supplier evaluation processes help them to buy quality products and manufacture best in class modules. As a domestic manufacturer, Vikram Solar is focusing on sustainability in Indian solar growth.

44 SmartEnergy Sept 2016

But Gyanesh Chaudhary is worried that low bids might increase the access of low quality imported modules in the industry (as India doesn’t have a uniform law against dumping). He believes that India should focus on long term sustainability of solar energy generation (which low quality modules are unable to provide) and development of domestic manufacturing capacity, rather than reducing bid prices any lower. He also believes that there are certain issues that Government needs to address first. Land scarcity, lack of closer industry-government cooperation, slow skill development, complexity of subsidy structures, delays in land acquiring processes, and lack of safe guards against solar equipment (module) dumping are few of these issues that are slowing down the growth of solar in India. Gyanesh Chaudhary suggests that to remedy these problems, Government should invest in creating land banks, making it easier for the companies to build factories. Although, Government is welcoming suggestions from private companies to improve its solar development strategies, more active involvement from both parties are required. Today there are skill development campaigns in India like ‘Suryamitra Skill Development Programme’, but we need more industrial training institutions to see Prime Minister Shri

Narendra Modi’s dream of creating 50,000 skilled solar workers into fruition. A uniform policy structure for subsidies can also help domestic manufacturers and encourage new entrepreneurs to build solar companies. Nonetheless he is very optimistic about the Government backed policies, regulations, and initiatives. As solar industry is dynamic in nature new challenges appear frequently. Intensifying global competition can be identified as the biggest challenge for Indian solar entities. But, Vikram Solar doesn’t see it as challenge, they see it as an opportunity to grow with the global solar industry. Their dynamic team and stringent quality maintenance standards support them in claiming a bigger share in Industry in the coming years. They have implemented a structured workflow and practice industry accepted protocols. Vikram Solar use their hands on experience in handling projectsof different design and stature to ensure their clients uninterrupted execution. They focus on timely delivery and have a strong track record that shows their commitment to quality ■

ACME Cleantech Solutions Private Limited

Delivering on the promise of Clean Energy Innovation is etched in the ethos of ACME and Manoj Kumar Upadhyay- Founder, Chairman and Managing Director, ACME Group with several patents to his credit has successfully established ACME Group as a leading energy solution provider in India and Africa.

n May 6th 2016, Renewable energy firm ACME won bids for developing 200 mw solar power projects under auctions conducted by SECI and NTPCBSE in Andhra Pradesh and Telangana. ACME won the largest share of 150 mw out of 400 mw at fixed tariff of Rs 4.43 per unit in addition to Viability Gap Fund of Rs 55 lakh per mw. The bagging of this tender, expands the overall portfolio of ACME Solar to 1654 MW and growing. This achievement should not be viewed lightly by any means, ACME reached this incredible height under the guidance of its founder, Mr. Manoj Kumar Upadhyay in mere 14 years. This is the story of ACME’s journey to the top. ACME Group is a leader in the field of clean energy with opera-

tions in solar power generation, lithium-ion based energy storage solutions and energy management of telecom towers in India. The company prides itself as a pioneer in the development of green technology solutions that are environment friendly, energy efficient, & cost effective. Mr. Upadhyay , established ACME to provide radically new technology solutions through intensive research and development in a market where it is common to just introduce new solutions by making incremental changes to existing technologies. His visions have transitioned ACME to a leading solar power developer in India with an increasing global footprint. As of today ACME’s commissioned project stands at 700 MW DC and is committed to develop

7500 Mega Watt (MW) of Renewable Energy Projects during the five year period of 2015-19. Besides generating 12000 Million Units of green and clean power annually, these projects will also create employment for around 4000 persons, directly and indirectly and prevent Carbon Emissions of around 10000 MT per year. ACME highly regards being an early entrant in the Indian solar sector helped to achieve its planned growth. The large knowledge base accumulated over the years significantly help ACME to introduce disruptive solutions, thus shaking up the sector by implementing many new initiatives first time at large scale in India. ACME mainly attributes its success to factors such as: ii Design: Its PV plants have been designed with optimum design engineering. The PV modules and Inverters are chosen of Tier 1 Manufacturers having global foot prints with financially sound balance sheet. Detailed technical and commercial diligence is prepared of similar specification of products from other Manufacturers. ii Vendor Management: Majority of the BOS items are sourced through the competent suppliers and deployment is done through the vendors who have pan presence in India and established credentials in their field of competency .The installation team, suppliers / vendors are provided

Cover Story with necessary training to impart skill set as per the project need and design philosophy. ii Effective Management: The entire supply and deployment arrangement is planned and monitored at very minute level on daily basis. ii Innovative Solutions: Seasonal PV module tracking arrangements have helped to reduce the DC capacity for about 10 % along with reducing BOS cost. Selection of the project locations near to GSS has reduced the Transmission line length and losses in account to power transmission. Implementation of Pooling Substation arrangement has helped to avoid the need of multiple bay requirements at GSS end, thus reducing multiple transmission lines with towers and also multiple project consolidated in a single location

on Lithium-ion Technology. These solutions are viewed as a game changer in the energy sector as the conventional technologies are highly polluting as they are based on Lead Acid & Diesel consumption. Energy Storage is also one of the key focus areas of ACME and they are developing various customized solutions to meet application specific requirements. Further, the company is working towards building a new generation utility based on natural resources where power is generated & distributed based on consumption and behaviour of society. The Indian solar sector is going through a very interesting transient phase and as the sector is getting more competitive, with aggressive bids quoted, there is a general fear in the actual realization of these prices. However Mr. Upadhay is very optimistic and believes we should not get carried away with such numbers.

Through such innovative and disruptive ideas, ACME has been at the forefront of the solar sector Nonetheless, he does identifies scenario in the country by leadthat there are some issues which ing at the competitive bids at the are impending the growth of Central Government and the sector and the State Governhence require ment led bids, immediate which translates attention. to cost effective One of the power to the main conend consumcerns are the ers.

Most of the lenders in this sector are Public Sector lenders who are attuned to lending large thermal power projects. Financial closure of conventional power project, wherein gestation period is around 3-4 years, can be achieved over the horizon of 12-14 months and disbursement thereafter. However, financial closing of Solar Power Projects needs to be achieved within 3-5 months to enable the project commissioned within 12-15 months as per the PPA. Mr. Upadhay also adds that the biggest challenge for the industry in general is to manage the evacuation of the renewable plants, which is intermittent in nature. The kind of volumes getting added into the grid, grid safety would be of paramount importance. Therefore, the scheduling also needs to be as accurate as possible. Granting all these issues, Mr. Upadhyay adds that the intent of Government of India is very clear and the kind of support which this sector has been receiving is phenomenal and the thrust is not only on the policy framework but also on the implementation. Innovation is etched in the ethos of ACME, it strives to provide sustainable solutions in Energy Conservation, Energy Management, Energy Generation and Energy Storage. Against many odds, ACME has led the Indian solar by focusing on green technology and needs of the society and hence coming out with indigenous solutions to cater to these needs ■

First Solar

Taking Energy Forward An Industry Veteran, strategist and guiding force behind the success of First Solar in India Sujoy Ghosh, Country Head, First Solar India looks forward to continuing to grow the thin film solar energy market within India.

n 10th August , First Solar announced that it has successfully connected 130 mw solar power utility to the national grid as it commenced the commercial operations of two of its units at Andhra Pradesh (80 megawatt) and Telangana (50 megawatt). These projects are part of the 260MW project portfolio wholly owned by First Solar in India. The 130 megawatt plants collectively will produce enough energy to power approximately 227,500 average homes in India, and will displace over 204,000 metric tons of carbon dioxide per year. The project will be powered by more than 1.4 million First Solar modules, offering highly predictable energy in all climates and applications. First Solar has been present in India since 2011 and has hence flourished under the leadership of Sujoy Ghosh, Country Head, First Solar India. Their primary business activities include sale of modules to 3rd parties and development of utility scale PV solar assets. Their main areas of operations are in the states of Telengana, Andhra Pradesh and Karnataka. Presently India is the key strategic markets for many global companies. The opening of the solar sector in India, motivated the USbased solar energy panel maker First Solar to embrace the Indian market. First Solar was the first global entrant in the Indian market since the inception of the National Solar Mission in 2011 .Consistently since December of 2011 to till date, First Solar has the highest market share in India amongst all PV manufacturers and this

demonstrates the suitability and competitiveness of its CdTe module technology for Indian conditions. First Solar has become the first thin film PV modules manufacturer to ship 1 GW (DC) of PV solar capacity to India. The growth of thin film technology in India is highly beneficial for the region. Thin film modules today have higher conversion efficiency and require less land per MW, compared to polysilicon-based modules. In fact, First Solar’s technology advantage is particularly pronounced in the hot and humid climate of India. Based on the past 3-4 years of data from an installed base of 1 GW of First Solar’s technology installations in India, there is clear evidence that First Solar’s CdTe based thin film modules produce 5-9% higher energy for the same installed capacity as compared to silicon based modules. The reason is that CdTe as a semiconductor material degrades at a significantly lower rate on temperature rise as compared to silicon. Further CdTe responds better under diffused light conditions and is agnostic to shift in the spectrum of light caused

by humidity in the atmosphere, unlike silicon where the performance drops under these conditions from their rated efficiency. First Solar continuously tries to optimize the tariff of the solar power plant to make it even more compelling for the consumer to opt for a higher degree of solar energy as part of their overall energy entitlement. The company attributes this to its adoption of technology that is continuously improving the energy yield and long term reliability of the CdTe modules. Also as a developer, their goal has been to bring lower cost of capital to the projects by mitigating the prediction, construction and financing risks and deliver a competitive cost to the

Cover Story provided to the developers. Investment hurdle rates differ in various organizations depending on (a) their risk perception of the various factors that influence the investment and (b) their internal cost of capital. In Mr. Ghosh’s opinion, at the prevailing tariffs the levered pre-tax return on equity is in low teens. He adds that if the companies are willing to invest at those hurdle rates, and have access to lower cost capital, then we would see more capacity being created in India driving overall demand growth for Solar PV. consumer. First Solar credits its success and growth to (a) supporting developers in Indian market with their module technology and other services and (b) investing their own capital to develop utility scale PV power plants. The utility scale solar market in India has grown exponentially in the past few years. Sujoy Ghosh, is very optimistic about the growth

opportunity in India .He believes that First solar would continue to do well in the coming years due to various factors namely (a) a demand for solar energy which is unsubsidized and is driven by fundamental economic activity (b) a very transparent and open market mechanism (c) higher energy yield demonstrated by CdTe module. However Mr. Ghosh believes one of the challenges impending the growth is the cost of capital

Given the energy deficit, need for energy security and the sustained economic growth, the potential clearly exists for 100GW of solar PV in India. This represents a significant market opportunity for First Solar to provide thin film module technology and services to other developers as well as invest into development of solar PV projects to create and derisk assets which can be offered to investors seeking predictable long term returns ■

"This would create a more competitive and sustainable ecosystem in India, which Trina is actively looking into the opportunities to engage in" adds Gaurav Mathur. However, he also believes that there are certain challenges that need to be overcome in the Indian solar sector. The challenge is to continuously invest in R&D and technology innovation to increase efficiency and product quality and reliability, which requires more money, while at the same time there is a need to reduce cost, without compromising on quality, and bring more economic savings to the market while increasing

the manufacturing efficiency and capacity to meet the growth of markets and demands. One way to ensure low tariffs, Trina is looking at ways to drive down costs and the component level and improving manufacturing efficiency while diversifying their manufacturing and supply chain to go beyond China. Trina is presently looking at a manufacturing possibility in India. On January 12th, 2016, Trina held the foundation stone laying ceremony for the first manufacturing base in Andhra Pradesh. Currently, they are doing a feasibility study, cost analysis and reviewing the demand situation in India. They need to look at total supply chain solution to keep manufacturing costs down to be as cost competitive as Chinese made panels, to meet the price target of the market, and need to be cautious to ensure the viability of the

Wind turbine retrofit solutions by DEIF

Why Retrofit - The Current Scenario Over the last three decades, thousands of wind turbines of all sizes have been installed worldwide and most of them are still operational today. The number of out-of-warranty wind turbines in operation is rising and there are many wind turbines in India that have been running for more than a decade. It has become a gigantic task for the wind farm owners to maintain the recurrent failing turbines with no or little support from the OEMs. This eventually results in lost revenue as the turbines are non-operational for most of the year, including the high wind season. Older control systems might result in less reliable functioning and reduced operating efficiency. Owners do not believe they are getting the most out of their turbines, so they are looking to improve their existing fleet. Another reason is that the owners of older turbines no longer have the spare parts available for replacement of these parts with more modern components before something breaks and they are unable to fix it. DEIF’s Answer to the Challenge

54 SmartEnergy Sept 2016

DEIF presents the wind farm owners with a less risky and less capital-demanding option of upgrading their existing wind turbines through retrofitting solutions to perform as effective as new. Retrofitting key components is a cheaper option than replacing the entire turbine. DEIF’s advanced retrofitting solutions are a boon to the wind farm owners who are struggling to raise finances for new projects, or want to avoid the risk of major investment in an uncertain economy. By upgrading to DEIF’s state-ofthe-art technology, the turbine’s efficiency and performance will improve, which cuts maintenance and running costs by keeping them low over the long term. The turbine owner gains additional revenue against a fraction of the cost of investing in retrofitting solutions. Wind Turbine technologies have evolved tremendously and the possibilities for retrofitting older turbines is now both financially and service wise more attractive than ever. By retrofitting older turbines with DEIF’s improved control automation technologies; there is now a secure, cost effective and simple way of extending older turbine’s productive life span and keeping them running on site.

How Do We Do It? The best way to optimize production from old wind turbines and reduce service/maintenance costs is to analyse the wind turbine condition and take necessary measures for improvement. The turbine’s operational life can be extended by upgrading critical components. DEIF inspects and analyses your existing turbine to produce a report detailing the condition of various parts of your turbine, bypassed protections, earthing etc. Based on this report, DEIF offers solutions that are required to transform your nonperforming/low performing assets into a profitable business entity. DEIF also recommends changes in the existing system that is outside DEIF’s scope. DEIF’s solution can be easily interfaced into the existing user interface. Flexible and reliable control solutions being our strength, we deliver everything from complete turnkey solutions to individual components. DEIF’s retrofit solution and the scope of work viz. wiring, installation, training etc. is tailor-made according to your needs. At DEIF, we continuously strive to improve the performance of the wind turbines and make necessary upgrades to the application and embedded  www.supersmartenergy.com

DEIF’s Retrofit Solution Package Includes: Advanced Wind Turbine Controller, AWC 400 DEIF’s Control Systems are can improve wind turbine power performance in all stages of a wind turbine’s life cycle. Software updates keep the turbine’s controls up-to-date and efficient. Both new and old installations can be optimized and tuned, and new features can be added in retrospect according to need and site conditions. Smarter controlling can increase overall energy efficiency, and lessen loads and reduce wear of mechanical systems by giving accurate signals to the major components used in the turbine.

Thyristor Control Module, TCM-2

Based on a modular rack concept, the AWC series provides compact, flexible and servicefriendly solutions – right from simple plug-and-play rack modules to cabling fitted with pluggable connectors. The AWC series is designed and constructed to meet the strict requirements for maritime use which exceed industrial norms by far. Thyristor Control Module, TCM-2 The new generation of DEIF’s Thyristor Control Module, the TCM-2, has been designed for heavy duty operation in the harshest of environments, and can typically be applied as a soft starter for asynchronous motors and generators, cut-in-controller for asynchronous wind/water turbine generators or 3-phase solid state relay for capacitive loads.

It is approved by major classification societies such as GL, CCS, RS and DNV. The WSS REC is ideal for harsh environments. Normal operation does not require service and maintenance. The static (ultrasonic) measuring principle provides a durable solution that does not wear out – no more need for changing bearings. The sensor is based on three ultrasonic transducers placed in a triangle. It measures wind speed and direction by measuring the time it takes for the ultrasound to travel from one transducer to the other two. The wind sensor is suited for maintenance-free operation. Extensive field tests in rough seas have shown that the WSS REC is suitable for both offshore and onshore. The field tests have been supplemented by laboratory testing of extreme temperatures, water resistance, vibration and shock. DC Power Supply, DPS-1 To ensure stable and reliable

operation of a wind turbine, the power supply is critical. Most standard industry power supplies are not designed to cope with the real-life operation demands of a wind turbine – operation temperature span, mechanical robustness, tolerance towards ESD, etc. That is why DEIF Wind Power Technology has designed a series of rugged DC supplies to support the second-to-none reliability of our control systems. The power supplies feature compact and lightweight switch mode design and at the same time – similar to conventional transformer designs – they have no moving parts as they have been designed for convection cooling, thus no maintenance- demanding fan is required. The series of power supplies is designed for an operation temperature range of -40 to +70 ˚C, supporting reliable start-up and operation regardless where in the world the wind turbine is operating. DEIF SCADA Manager DEIF Wind Power Technology offers a full set of SCADA solutions for remote control and supervision of wind turbines. The SCADA system can run on a computer in the control room of the wind park or it can run on any internet-connected computer, accessing the wind park using TCP/IP.

Main features of the SCADA system are: ii Turbine overview ii Turbine control ii Log viewer ii Report generator The aim of the DEIF’s retrofit and modernisation exercise is to ensure that we make the upgrades that allow our clients to make wind power business profitable. Extending a turbine’s life and improving its performance through retrofitting is more likely to be of interest to independent power producers (IPPs) as the life extension of wind farm assets also allows an automatic increase in their company’s asset value and increased profits over a longer period. Deploying DEIF’s retrofitting solutions would be an intelligent, strategic business decision as it will enable the wind farm owners to make the most of their existing old wind turbines with minimal investment. Backed by local support team, choosing DEIF implies reliable and fast on-site service & support ■

Spot Light be sent to an engineer’s mobile. Corrective action can then be taken immediately. Diagnostics One of the other effective utilisation of SCADA can be in diagnostics of plant faults. The inverter, HT/ LT panel, string boxes and modules are used in large quantity. It is essential to analyse the fault in the system, otherwise, searching for a fault in a single system can be tedious job. Module level diagnostics is also possible in some SCADA systems.

Milind Upadhye

n recent years, many solar plants have been constructed in this country. Almost all the solar plants have (Supervisory Control And Data Acquisition) SCADA system, but the effective utilisation of these systems remains doubtful. It is similar to how a person with the latest smart phone might be completely unaware of all of its features. This article tries to explain the best possible use of the SCADA systems in solar plants. Most Common Use Most common use of the SCADA system is to automatically report the daily generation to the top management. Hence, at the end of the day, the top management receives an email or a text message reporting the daily generation. Contrary to what many people think, this is not the only objective of SCADA, it is important, but this is not the ultimate test of the system. Effective Utilisation Although for the top management, reporting daily generation automatically may be an important feature but for the project team, generation team and engineering it is totally different. Some of the features which need to be observed when selecting the SCADA system for the plant are: Loss Analysis

60 SmartEnergy Sept 2016

P reve n tive Maintenance

On a real-time basis, SCADA can calculate the loss, and the source of the loss. The loss can be from modules, strings, DC cables, inverters or AC section. SCADA can give these figures, and losses can be corrected. Weather Forecasting A good SCADA system can receive data from weather satellite (via internet). Predicting future weather conditions, the plant generation can be simulated and based on it, schedule maintenance can be planned. Alarms SCADA system can be programmed for multiple alarms. Alarms can be programed in such a way that the loss of generation can be corrected immediately. Alarms like inverter off, or string not generating enough power can

Earlier detection of the fault or likely failure detection of the part can bring many losses especially financial losses in control. Normal early warning of temperature rise is a very effective parameter to check for inverter or other failures, air flow management or even filter cleaning options. Flexibility Apart from all these feature list, SCADA being a software product needs a lot of flexibility. The meter, inverter, string box can be changed, reports needs constant upgrades, the screen needs to be modified based on user requirement. Learning Easiness Any software product needs ease of use. The user is accustomed to certain types of key stroke operations, familiarity of the screens and functionality. SCADA should support the same otherwise user will have a tough time to use SCADA.

Spot Light Controlling The question is always asked, if solar SCADA has any controlling element. In smart grid applications, when the power needs to be controlled, the grid can automatically control the inverter power using grid control. Reactive power controlling is also one of its’ main feature. Even switching off the SCADA computer during night time is possible. All this can be achieved by a SCADA system. PRISTINE SCADA by KAIHATSU TECHNO CENTRE Kaihatsu Techno Centre Pvt Ltd is an Indian company engaged in SCADA software from 1999. It has completely developed and designed its’ own software product and it is trademark registered as “Pristine”. The SCADA was originally designed and made for Petrochemical Refineries.

Solar PV

Optimize Output and Profitability of a Solar Plant

o reach the objective announced to UNO, India needs to optimize the output, the quality of service and the profitability of all its PV systems, whatever is their size. And to reach there, it is crucial to follow the best practices of the Operation and Maintenance (O&M). The health of the Solar PV systems should be monitored continuously for their better performance and maintenance. For PV systems installed at Urban or even rural locations, remote monitoring capabilities provide the information in advance when system performance is degraded or is likely to fail. Based on this information, preventive maintenance can be carried out to improve the performance and life of the system, thereby reducing the overall operating cost. To enable this, it is necessary to collect three main levels of data: ii Meters that provide the exact status of the production or consumption and working information ii Parameters and alarms that come from the central device of installation, like inverters in a solar plant, to have a better view of the equipment situation ii Environmental information coming from sensors (irradiance,

64 SmartEnergy Sept 2016

temperature, hygrometry, wind speed, etc)

by Webdyn‘s latest developed version of WebdynSun in France.

To help you with the smart collection of data, Webdyn has developed two main products:

2 numbers of WebdynSun were installed on to the site since the SCB units were far apart from Inverter & Meter. TMEiC inverter over TCP MODBUS & Secure energy meter over MODBUS RTU were connected in single WebdynSun to monitor their data & performance based on the custom frequency, similarly all the Strings were connected through SCB onto another WebdynSun in order to monitor individual Module as that helps to reach the particular module in case of any error or an event. Complete information is being transfered to the Portal of the Cleanmax for the deeper analysis. The main USP here with WebdynSun is that it can work with any portal suitable to process CSV file formats & hence more deeper analytics like Performance Ratio, Specific yield, Reduction in CO2 & Real cost saving etc. can easily be calculated.

WebdynSun The WebdynSun gateway is used to monitor and collect data from a solar plant installation. The gateway brings together on a single unit all the indicators from the inverters, the electric meters and the environmental sensors (sunshine intensity, temperature, wind speed, etc.) through a set of multiprotocol interfaces (specific inverter protocol, Modbus, wired ). WebdynModbus The WebdynModbus gateway enables to manage or collect data from Modbus equipment (slaves). On a single box, the gateway includes a RTU Modbus and TCP Modbus interface and Ethernet and GPRS interfaces to communicate with the information system. Case Study 1: Metro City (Urban Area) A 1.5MWp grid-tied Solar PV system was installed on the rooftop of the TVS Lucas, Chennai. The performance monitoring system for the installation is provided by Webdyn. The system is supported

Case Study 2: Rural Area A 6KW off grid battery based Micro grid Solar PV system was installed in the very remote village named Bhatipara in Jawhar district of Maharastra the local tribes there are not having any grid supply, no clean water, no approaching road & hardly any 2G signal of Voda www.supersmartenergy.com

remotely.

So it is very hard to reach the site for the Microgrid developers in case of any minor fault / event & cost them a lot in terms of time & money.

The data in the form of zipped CSV files are being transferred onto the FTP server of CES, Pune & they are providing the relevant analyses to Gram Oorja to monitor their site on regular basis remotely.

That system is supported by Webdyn‘s latest developed remote monitoring version of WebdynSun in France. One WebdynSun with Vodafone 2G SIM card & extended GSM antenna for better signal reception was installed onto this microgrid site to monitor the crucial information about Batteries, Total Generation through Inverters, Active forward energy from Energy Meter & most of the relevant parameters from the Inverters to track the events & errors

This practice has not only saved their time & lot of money to visit the Microgrid every time for any unknown reason of fault but is also providing them a lot more crucial information on to the battery system like: temperature, gravity, charging, discharging etc. along with the Grid Supply information. Hence setting up best O & M practice as above with Webdyn that also gives you the freedom

to choose the devices (Inverters, Meters, Sensor, SCBs & other Modbus devices) & the Portal of your choice based on the project requirements contributes greatly to reduce power failures and make solar plants operational nearly 100% of the time. The output and the quality of service are strongly increased ■ To find out more about WEBDYN and its products in India, please visit the company at Renewable Energy India, (7-9 September), Greater Noida, at stand K34.
