Author: Mr. Pranav Master, Director, Energy and Natural Resources, CRISIL Infrastructure Advisory
Energy storage – the next big step in electricity market transition – is crucial to bridge the foreseeable demand-supply gap in electricity, ensure sustained growth, and maintain a stable grid. That entails a clear, long-term policy and enabling regulatory framework focused on grid management and upscaling flexible sources. Why flexibility?
The electricity market is in transition, on both, demand and supply sides. On the demand side, the push towards universal electricity access and 24x7 Power for All has brought about a shift in the consumer profile. Adoption of distributed generation and use of electric vehicles is set to increase. And rapid climate change is leading to significant seasonal variability. On the supply side, the share of renewables in the energy pie is estimated to rise substantially to 12%-15% by 2025, led by strong government thrust and economic attractiveness. Ergo, a mismatch between the demand and supply curves is inevitable. This warrants building flexibility in the grid to ensure system reliability. CRISIL Infrastructure Advisory believes, a conducive environment needs to be created to ensure uptake of storage solutions. Following are certain measures that could be implemented in this regard.
Suggested measures to charge up the energy storage space:
Mooting ‘storage-as-a-service’
Merely having energy storage is not enough, its design is crucial for meeting cost efficiency. So far, ~60 MWh battery based energy storage capacity has been deployed on a pilot basis in India. Recently, a large-scale, 1. 2 GW renewable energy proj ect with storage was auctioned by the Solar Energy Corporation of India (SECI) to meet peak requirements. All of these proj ects are designed for a specific application and service duration. However, deployment of storage for single application may hinder optimal utilisation of storage capacity leading to higher cost of stored energy. For instance, tariff discovered in the above cited SECI tender ranged between Rs 6. 1 – 6. 9 per unit for peak power supply, which would be higher than that from most thermal and hydro sources. How can the issue of high cost or affordability be addressed? We believe that energy storage proj ects could be designed and deployed on ‘ storage-as-a–service’ basis across power systems for multiple applications such as frequency control, black start, voltage support, capex deferral, etc. That would extract maximum value and drive down energy costs. Moreover, ‘ As-a-service’ concept augurs well for capital intensive and technology led industries since these risks are not assumed by end-users. In fact, parallels such as these can be found in different industries including software-as-a-service, transport or mobility-asa-service, etc. Thus, incorporation of such learnings as well as policy and market facilitation, highlighted earlier, would ensure deployment of storage solutions on a large scale thereby enabling electricity market transition.
Electricity markets are in a transition phase with changing dynamics on both, demand and supply. Therefore, a well-defined and long-term road map with policy and market enablers should be put in place to boost adoption of energy storage. SOLARQUARTER | MARCH ISSUE 2020

WE ARE POISED TO REMAIN AS TOP CHOICE OF OUR CLIENTS DUE TO ROBUST TECHNO-COMMERCIAL OFFERING Mr. Manish Narula, Head of Business Development & Senior Sales Director, Jinko Solar
PLEASE SHED SOME LIGHT ON THE GROWTH PLANS FOR INDIA. WHICH ARE THE KEY MARKET SEGMENTS THAT YOU PLAN TO TARGET THIS YEAR? Jinko Solar sees tremendous potential in Indian Solar market. We believe in long term investment. Considering this, we have developed versatile, well experienced strong team in India from diversified backgrounds (IPPs, Developers, EPCs & Module manufacturers). Our team comprises of Sales and Marketing professionals, Quality and After service, Legal, Finance, HR & Sales Support functions. This robust team is a strong indicator of Jinko’s growth plans for India. Last year, Jinko was on top of the list for Mono PERC orders in India. We already launched our highly competitive and strong quality Global product in Indian market. Our key market segments are Utility Scale Solar, Commercial & Industrial and Open Access. We are poised to remain as Top Choice of our clients due to robust techno-commercial offering in line with prevailing Tariffs in these segments. For Rooftop segment, our high efficiency module series is obvious selection over competition due to its inherent benefit of more capacity in limited space.
HOW DO YOU SEE YOUR COMPANY EVOLVING OVER THE YEARS? For the last consecutive four years, Jinko Solar is maintaining its position at the top in Global Tier-1 list, be it for highest annual modules shipment or highest bankability or world record module efficiency or several high level Industry awards and accolades. Due to solid management support towards facility expansion, an ability to identify future market trends and capabilities to implement technical innovations in our products and services, Jinko Solar can supply an industry leading bankable Mono PERC product series across the globe. At present, Jinko Solar is projected to deliver around 19 GW of Solar Modules globally in 2020, which will be over 30% Year-on-Year growth.
TELL US SOMETHING ABOUT THE RECENT TECHNOLOGICAL INNOVATIONS IN YOUR PRODUCTS AND SERVICES? Jinko Solar has always been in the forefront when it comes to Technological Innovations. Our R&D team, world class Quality Control, Manufacturing capabilities & robust supply chain ensure that we launch new products with future technologies on regular basis. It helps us in consistently staying ahead in the market. Our recent launch is Tiger modules series. It uses Tiling Ribbon technology, Half Cut cells & Nine Bus bars to achieve high efficiency and high yielding Solar Modules of 455 to 460 Wp . It is available in both variants: mono-facial & bifacial. When it comes to Services, we have in-house after-sales technical support team to address any field issues, with shorter turn-around-time support mechanism. Also we extend support to our clients by helping them in choosing an appropriate viable module technology suitable for its site conditions.
WHAT ARE THE LATEST TRENDS AND INNOVATIONS IN MODULE TECHNOLOGY? Offering higher Module wattage is a way to remain competitive in highly competitive Solar Power Tariffs. Many module manufacturers are adopting bigger cell size to offer higher Wattage modules. Due to this, the overall module size is becoming larger and causing site handling and breakage issues. The key here is to achieve optimum cell size and still meet higher Wattage requirements. With the help of R&D driven analysis, Jinko strongly believes that cell sizes up to 163 mm are the most optimum and have ability to become mainstream products in 2020 and beyond. N-Type high efficiency modules are also entering into market. But these are yet to be commercially adopted in Indian projects. However, Tiling Ribbon type modules are highly expected to become the most preferred choice for Indian Solar Developers due to higher yield and lower LCOE to match with competitive tariffs & win the upcoming bids.
Jinko Solar has always been in the forefront when it comes to Technological Innovations. Our R&D team, world class Quality Control, Ma n u f a c t u r i n g c a p a b i l i t i e s & r o b u s t supply chain ensure that we launch new products with future technologies on regular basis. AS PER YOU, WHICH ARE THE TOP 2-3 KEY COMPONENTS OF A MODULE, WHICH HELP IN LONG AND SUSTAINABLE LIFE OF SOLAR PROJECT? As we all know that Solar Module is an assembly of various big and small components. The key here is to identify & use best compatible components suitable to Indian climatic conditions. There is no room to compromise on quality on any component. Especially, post BIS, all module components have to be of highest quality standards. Out of these components, Solar Cell & Backsheet are critical to determine long and sustainable life to the Solar PV Plant. As per our standard practice, Jinko offers its own Solar Cells, exceedingly reliable and manufactured at Jinko’s high-level quality workshop. Another key component Backsheet, where Jinko uses DuPont’s Tedlar material, can offer reliable longer product life in tough Indian climatic conditions. We strongly believe based on our experience across the globe, that if any client considers above key components, their Solar project life can be enhanced favorably.
Wi t h t h e h e l p o f R & D d r i v e n analysis, Jinko strongly believes that cell sizes up to 163 mm are the most optimum and have ability to become mainstream products in 2020 and beyond.

TELANGANA STATE IS FORGING AHEAD TODAY WITH ITS CONTINUOUS GROWTH WITH A TENACITY TO OCCUPY MORE AND MORE SPACE ON THE SOLAR PLATFORM OF THE COUNTRY. Shri M.Venkateshwarlu, President, Telangana Chambers of Commerce and Industry
KINDLY LET OUR READERS KNOW ABOUT THE INITIATIVES TAKEN BY TECCI FOR THE GROWTH OF SOLAR SECTOR IN TELANGANA STATE ? When the state was newly formed in June 2014, TECCI submitted a detailed Report to the Government covering all aspects of Trade, Commerce, Agriculture and Industry. We made a significant mention about the power sector with a special focus on the need and potential of Solar sector in Telangana state. We are glad that many of our recommendations have been accepted by the Government and they are reflected in the relevant Government Orders. These recommendations include establishment of solar power plants, Rooftops and Floating Solar Plants. We wanted Hyderabad to be converted into a Solar City on then lines of Gujrat and Karnataka immediately after the state came into existence. We are aggressively on the job to achieve this goal not only in Hyderabad but also across Telangana region wherever an adequate radiation is found viable. Telangana State is today forging ahead with its continuous growth with a tenacity to occupy more and more space on the Solar Platform of the country. We have a team of experts who are making a study thoroughly at every nook and corner of the state. This Report will be ready some time in the month of April/May 2020 which will be submitted to the Government Authorities for initiating necessary measures.
HOW CAN THE ROOFTOP SECTOR IN TELANGANA BE FURTHER STRENGTHENED? WHAT ARE THE EFFORTS BEING MADE BY TECCI FOR ITS GROWTH ? Rooftop Sector in Telangana is getting a momentum contrary to the expectations when compared to the other states in the country. The State has an excellent potential with average solar insolation of 5.5 KWH/m2 for more than 300 sunshine days. Hence, there is an ample opportunity and scope for further growth of this sector provided some more revolutionary measures are accepted and kept in place by the Government. In fact, the Municipal Corporations, Distribution Companies and Telangana State Renewable Energy Development Corporation (TSREDCO) have a great role to play for the growth of Solar Rooftops. The decisions of the prospective Developers/Producers depend on their support and incentives. TECCI is making its following efforts with the Government in the process of strengthening this sector to be one of the top states in the country. The new buildings in all Domestic, Commercial and Industrial sectors should install the roof top solar plant preferably covering 30% to 50% of their roof space or maximum space which they can afford. This should be a condition for granting building approval by the concerned authorities. Strict and efficient implementation of Single Window Clearance for open access projects without impediments of every sort by the concerned authorities. This should be a time bound program. If the approval takes more than the specified time, it will be simply presumed that the clearance is obtained the way the industrial policy is designed by the Government in the year 2015. Applications for Net Metering should be completely online with singlewindow approvals. Consumers availing net metering should also be allowed to avail offsite solar. Data regarding the DISCOM’s distribution transformers should be made available publicly to enable the developers for their upfront planning.
SOLARQUARTER | MARCH ISSUE 2020
Some of our Members strongly feel that they need encouragement and a helping hand from DISCOMS for establishing the plants under captive mode as per Electricity Rules 2005. In fact, the developers are the babies or partners in progress of DISCOMS and they cannot afford to be their competitors. TECCI is making its efforts by conducting suitable awareness programs through workshops, seminars, panel discussions, national and international conferences. The Developers in the Domestic, Commercial and Industrial sectors are invited to these events as stakeholders for this movement.
Rooftop Sector in Telangana is getting a momentum contrary to the expectations when compared to the other states in the country. The State has an excellent potential with average solar insolation of 5 . 5 K WH / m 2 f o r m o r e t h a n 3 0 0 s u n s h i n e days. Hence, there is an ample opportunity and scope for further growth of this sector provided some more revolutionary measures are accepted and kept in place by the Government. WHAT IS THE MARKET POTENTIAL FOR INDUSTRIAL ROOFTOP SOLAR IN TELANGANA? There is an immense potential in the roof top sector in the state of Telangana. The total rooftop potential in the city seems to be around 1700-1800 MW which contributes to the reduction of power demand by almost 15%-20%. This is something gratifying to note. We are on the job of arriving at the most authentic estimation at the state level through one of our sub committees exclusively appointed for this purpose. This committee consists of experienced and eminent professionals. This Report is expected soon. In addition to this, we are also approaching Residential. Industrial and Commercial Segments (RICS) for obtaining the data about the available shadow-free roof available at their disposal along with other key parameters such as type of roofs, connected load, voltage and consumption pattern etc. to estimate the potential.
ARE THERE ANY SOLAR POLICY REFORMS THAT YOU WOULD LIKE TO RECOMMEND? We would like to place the following requests before the Government of Telangana again for consideration. The Solar Power Policy 2015 has to be made more and more viable to attract the investors to build projects. Any draft policy in any area of operation needs to be finalized within an year to serve the purpose for which it was drafted. Making amendments can be a continuous process in the interest of the requirement and prosperity of this sector. We recommend that the benefits provided under this Policy have to be further extended for at least 2,3 years more in order to get the expected and estimated impetus to the growth of this sector.
PG 18
Though the current trends reveal a decline in the cost, better plant performance and its self-sustaining capabilities, the restoration of this facility would greatly widen the customer base for solar adoption in the state especially in sectors like Agriculture, Residential and MSME. We feel that the Income Tax may be exempted for this industry during the initial year. This can be calculated on the basis of capital investment minus subsidy, if any. This exemption can be made in two instalments also in the first and second year, if required. Captive power plants or open access solar rooftop plants may be permitted to the 50% capacity of the user which is existing in Gujarat without any restrictions or hassles. Net Metering is an extremely worthy facility provided by the Government which would contribute to tremendous growth of this sector while encouraging the customers and protecting the environment. But, unfortunately many of our Members and system integrators are getting frustrated taking it as a deterrent due to inordinate delays that are taking place during the process of net metering. There should be a streamlined procedure in place with all timelines for this purpose. If this process is made on line, it would pave the way for quick completion and commissioning of the projects. Billing settlement should change from six months to one year to adjust the units of consumption as solar IRR vary seasonally. Taking stock of the prevailing scenario in the states like Tamil Nadu, Karnataka, Haryana and Uttar Pradesh for an upfront review of their policy frameworks in respect of wheeling and banking facilities etc. This is to explore the possibilities of implementing in our own way in Telangana state for the accelerated growth of this sector. In the process of promoting green power revolution, the Government has to make the Solar Rooftop mandatory for the industries to enhance the installations in the state. Considering and exploring the possibilities for removal of barriers for industries in respect of quantum of generation as desired by the Industries in view of their capabilities and competence. Release of subsidy must be made simpler and fast. It is usually taking six months to one year. Most of the system integrators are small entrepreneurs and cannot sustain this delay in payment. Facilitating open access for renewable energy both for captive and third party sale to the extent of 50% use, allowing banking, strictly implementing RPO, concession in wheeling charges, considering the possibility of increasing the CMD limit of approval from 80% for installing solar power system.
WHAT ARE THE CURRENT BOTTLENECKS BEING FACED BY THE INDUSTRIES WHILE INSTALLING ROOFTOP SOLAR PROJECTS IN TELANGANA? Capacity limitation to 1 MWp seems to be one of the major hurdles for consumers who have enough space and load to accommodate more solar power.
SOLARQUARTER | MARCH ISSUE 2020
The industry feels that the discontinuity of providing subsidy on the part of the state Government is also an impediment to rise to the occasion for promoting green power revolution.
There are some administrative inconveniences right from obtaining permission to the installation of net meters which are to be taken up for an immediate and thorough review.
AS AN ASSOCIATION, WHAT STEPS HAVE YOU TAKEN TO ENSURE THAT MORE MANUFACTURING INDUSTRIES FOCUS ON GREEN ENERGY CONSUMPTION ? Fortunately, we have a strong and stable Government which is putting all the efforts for the accelerated growth of this industry. We have a very proactive Special Chief Secretary (Energy), Mr.Ajay Mishra, IAS, who has a strong vision and foresight for the growth of this industry in the state.The Energy Department is aggressively making use of the positive environment prevailing in the solar atmosphere in association with the Government of India to harness solar potential in the state. There has been an increasing demand continuously from the year 2018 with grown up industrial activity including MSME sector and the state touched a peak demand of 12,060 MW on 17th February 2020. Presently, we have total installed capacity of 95.21MW and an additional technical feasibility has been issued by the Government for another 40.14 MW. I also understand from one of the survey reports that it is about 5% of the total potential which is catered by solar in both residential and industrial areas and it may be even lesser than 1% when compared to commercial sector. Keeping this view, TECCI wants to boost up solar rooftops by conducting various awareness programs with all the stakeholders on the incentives offered by both the Governments of India and Telangana. TECCI is also making its efforts to establish a tie up between the Banks and owners of residential flats/ houses for the loan component. It is observed that the presence of CSR is very negligible in the clean energy sector as of today. TECCI wants to concentrate on this score and approach all major Indian companies in the country to take this initiative for Rooftop Solar in Telangana state. This will not only create employment opportunities and solve intermittent power supply but also reduce hundreds and thousands of carbon dioxide every month while meeting 30 to 50% of their power needs through onsite and off-site solutions at a reduced power cost. TECCI will have regular interactive meetings with the Authorities concerned and bring to their notice about the suggestions, recommendations and grievances of the Members. TECCI will make all the efforts to get the above reforms/recommendations considered by the Government to the maximum extent in order to make the industries to focus and concentrate on Green Energy Consumption.

India’ s need for and interest in energy storage and renewables+storage pairings is evidenced by the recent record-setting 1. 3 GW procurement by Solar Energy Corporation of India (SECI) for firm power. Int that procurement, batterybased energy storage proved cost-competitive with other types of storage – notably pumped hydro – to firm solar and wind output. Recent reports from India' s central electricity regulator and the Rocky Mountain Institute point to an immediate need of 3-5 GW of fast-response resources like energy storage to regulate frequency across the nation. Given the high amount of solar coming online and the accompanying need for flexible resources to support the evening ramp-up of electricity demand, resources like storage will become even more critical over the coming years. For example, The AES Corporation estimates the market size for storage in India to reach USD $50 billion in coming years.

BIG CHALLENGES IN EXECUTING ROOFTOP SOLAR + STORAGE PROJECTS
MR. ALAN KHOR Head of Engineering, Procurement and Construction Cleantech Solar
Energy storage is the missing piece of the puzzle to meet ambitious global carbon emission targets and the surging demand for clean electricity. When combined with a solar power generation system, a Solar + Storage system will compensate for some of the shortfalls of both traditional power generation and renewable energy production. It can help lighten up the load on an aging electrical grid and cut carbon footprint by reducing short term peaks in demand, managing grid instability and smoothening the intermittency issues when it comes to renewables. There is a lot of value that energy storage can bring, especially with the growing installed solar capacity in the market. Yet the energy storage industry is comparatively in its infancy. A few hurdles will have to be addressed before the market can see a scale-up in Solar + Storage projects: .1. . . . . .Cost: . . . . . . . . . . . .We have often heard of the term “Energy trilemma” in the electricity supply industry - the challenges to balance the three critical goals of energy security, environmental sustainability and affordability. Whilst energy storage could help address the intermittent nature of solar electricity generation and shift the reliance on fossil fuels to a more sustainable renewable source, the current cost of energy storage is still too high to make a viable business case. Despite drastic fall in energy storage prices, a Solar + Storage system still costs at least 3 to 5 times more than a solar PV system alone. However, on the bright side, the rapid developments in the energy storage industry are expected to further drive the growth in energy storage installations and economy of scale should ultimately lead to commercially viable system costs.
MR. SHRIPRAKASH RAI Head- Onsite Distributed Generation Business Amp Energy India
India’ s focus towards large scale solarisation- 100GW by 2022 is the primary driver that is making energy storage industry development a necessity. Although India has added 34. 4 GW of solar capacity over the years, most of this deployment has been in the utility space. Solar rooftop hasn’ t been able to scale considerably and achieve critical mass in terms of capacity growth. Solar by nature is intermittent and hence this limits the time period of its usage to only daytime. This intermittency can be constrained or even overcome by the use of electricity storage which represents a huge opportunity. Storage provides flexibility to the grid and will be able to ensure uninterrupted dispatchable, predictable and reliable power to satisfy the energy needs of the consumers whenever needed. Rooftop solar is being well accepted by C&I customers which contribute to about 70% of the solar rooftop capacity. Rooftop solar with storage provides a perfect opportunity to ensure greater uptake of rooftop solar power by customers. However, we are still in an early stage of energy storage for mass deployment. Higher costs of such a system due to the added cost of battery replacement and shorter life spans of projects pose a challenge in rapid deployment. As a nascent industry, it lacks historical data required by lenders to familiarize with the sector and hence investment into the sector adds another challenge.
2. . . . . . .Technology: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Grid-tied energy storage application is fairly new and there is insufficient publicly available field data on the performance and reliability of each energy storage technology and integration algorithm.
The bulk of the data are proprietary, making it difficult to take a long-term view of the technology risks. This issue is further compounded by several competing storage technologies and huge advancements being made by various manufacturers. The gaps in data and analysis capabilities can deter investments and hamper the growth of energy storage deployment. Therefore, it will be beneficial that such energy storage performance metrics can be made available in the public domain, with major stakeholders or energy storage players in the market to list their system yields in an accessible database. Such open knowledge sharing can bolster the development of best practices in Solar + Storage system deployment and could spark further improvements across such assets in the long run. 3. Application: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .In the paper “The Economics of Battery Energy Storage” published by Rocky Mountain Institute, energy storage can generate more value when multiple services are stacked across 3 different levels – behind the meter, at the distribution level, or at the transmission level. Depending on where you are in the value chain and the applicable local regulations, the full potential of the batteries can rarely be utilized and this limits the net economic benefit to the energy storage owner/operator. In particular, behind the meter value chain comes with great uncertainty given that policy and regulations may change over the system’ s lifetime. With the bulk of the untapped value still lying with Distribution and Transmission companies, clear and consistent policy support is necessary to tap into the full value of energy storage. 4. Lifetime: . . . . . . . . . . . . . . . . . . . . . . . . . . . .Energy storage systems typically last 10-15 years, less than half the lifetime of a typical PV system. Hence to manage energy storage life in a project, it would be critical to build in replacement cost for the energy storage systems and develop best practice in Solar + Storage system implementation so as to deliver the same cost-effective long-term benefit.
Energy Storage Systems are here to stay and the capacity of installations can be expected to grow exponentially over time in tandem with the already expansive growth of renewable power generation technologies such as Solar PV. Cheaper and more efficient energy storage coupled with renewable power systems are likely to play a key role as the world transitions to a clean energy future.

Solar photovoltaic (SPV) is an important source of renewable energy in the world, with overall global consumption over 11-16% in concentrated solar power and solar photovoltaics. Solar power is anticipated to become the world' s largest source of electricity by 2050. Bifacial technology has emerged with the capability to capture the module market with improvement in module manufacturing, cell efficiencies, and the overall rapid growth of the global PV industry. In recent years with significant interest throughout the industry and product offerings available, bifacial module technology has seen strong growth. ArcVera Renewables predicted that bifacial designs will dominate the utility-scale module market. Bifacial modules are coming up with new development like the incorporation of time-series albedo and detailed racking specifications, vertical fixed-tilt applications, optimization of ground cover for eg. groundsurface modification, wire management design solutions and new optimization of tracking algorithms. The global bifacial solar market is divided into polycrystalline solar panels, monocrystalline solar panels, and thin-film solar panels. The monocrystalline panel offers more energyefficiency whereas polycrystalline solar panels are cost-effective.
Due to the rise in the demand for electricity from industrial and commercial sectors the global bifacial solar panels market is anticipated to gain push. According to a report by Fortune Business Insights, titled, “Bifacial Solar Panels Market Size, Share and Global Forecast till 2026, ” various small, medium, and big enterprises are producing solar modules that have the latest technology infused. By focusing on design, cost, and efficiency of the solar panels enterprises are aiming to increase the global bifacial solar panels market sales. A study by LONGi Solar showed that bifacial can increase efficiency by 11% compared to a conventional solar panel system. To simulate bifacial energy output solar energy modelings software like NREL’ s System Advisor Model and PVsyst have incorporated algorithms.
HOW CAN BI-FACIAL MODULE TECHNOLOGY BOOST ENERGY GENERATION/ YIELDS?
MR. SAI CHARAN KUPPILI
According to a study, to realize the expected project value increase associated with 3-10% in bifacial solar project energy production, diligent and accurate measurement and modeling of site conditions, equipment specification, and project design, are recommended.
The bifacial module market is evolving, and pricing has changed with the larger module market and changing trade tariffs. Manufacturers might quote costs in the range of 6-10% increase from their equivalent mono facial modules. The present Levelized cost of electricity (LCOE) of largescale photovoltaic is less than that of fossil fuel. According to LONGI, consumers searching for maximum efficiency with fewer panels will opt for bifacial solar panels. Module manufacturers may promote gains “up to 25%” or plus but in practice, the gains are highly variable and depend on project site, design and characteristics according to Romero et al. According to a study, Asia Pacific is projected to lead the global bifacial solar panel market in the upcoming years, followed by North America and Europe. Indonesia. Countries such as Japan, China, and India are investing significantly in the field of solar energy which would boost the bifacial solar market. Latin America and the Middle East & Africa are also anticipated to give rise to the market.
According to Siason and Kedir, the electrical components of a bifacial panel are not much different than a mono facial panel. How to precisely model and estimate the production value of bifacial panels to help stakeholders in their acceptance and adoption of the technology is the main challenge. The methodology to technically assess and exactly estimate bifacial value panel technology is rapidly changing to a best practice. Bifacial technology and energy estimation are evolving and with them the level of comfort from financial institutions. Many countries are adding BiFacial solar modules in their project which itself shows the boost of these modules in the market. Ultimately any estimated gains in energy output and offtake, changes to system costs, and associated changes in these modules will be considered as an additional advantage in the solar industry.
Technical Director, South Asia Jinko Solar
High Energy Density is what benefits everyone on any ground mounted Solar PV Installations, which can be achieved by using High efficiency Solar PV technologies like Bifacial PV Modules. Bifacial Technology Module has got the advantage of absorbing both global horizontal irradiation on the front side of the module and diffused/reflected irradiation on the rear side of the module. Depending on the type of installation, location and albedo factor varies the range of gain in specific energy yield when compared to Mono Facial modules. Texture of ground surface, factors of albedo varies throughout the day and albedo follows the diurnal curve and makes the sensitivities of reflection getting fluctuated throughout the light day within the spectral wavelength. Jinko Solar has done an analysis with all possible ground textures within our Haining factory at China and noticed the gain of energy with Bifacial modules varies upto 19% and the same was ratified by 3rd party agencies. Out of available different models (dual glass / transparent back sheet) in Bifacial Modules, for tropical climatic zones like India, it is preferred to use transparent back sheet which always gets the benefit of resembling existing conventional Solar PV modules. Swan Bifacial Transparent back sheet modules has product warranty of 30 years due to high reliable characteristics of the materials being used with POE as encapsulant and PVF – Tedlar based back sheet with fluoric materials adding more value when compared to conventional encapsulant and back sheets. This even helps in obtaining low LCOE with the reduced economics of Capex & Opex calculations. Reduced linear degradation on Bifacial modules is one other advantage over Mono facial modules to have high specific energy yield on any specific year during the life of the plant. Acceptability on these Bifacial technologies is getting wide spread and acceptability across the globe and expected to capture the majority market share technology by 2025. Swan or Tiger Bifacial Modules ranging at power class 385-405 Wp or 450-470 Wp exhibits higher energy densities on the surface which has low soil moisture, in turn increases the reflectivity sensitivities of the soil to produce more energy from the rear side of the Bifacial module.

The energy output of a photovoltaic solar plant is closely linked to the efficiency of the solar modules. It is needless to mention that numerous designs and configurations are being developed and tried out to further enhance the output of the modules. One such configuration, which has demonstrated positive results is bifacial solar modules. Bifacial solar modules offer many advantages over traditional solar panels. Power can be produced from both sides of a bifacial module, increasing total energy generation. They are often more durable because both sides are UV resistant, and potential-induced degradation (PID) concerns are reduced when the bifacial module is frameless. Balance of system (BOS) costs are also reduced when more power can be generated from bifacial modules in a smaller array footprint. Bifacial modules can be manufactured using either monocrystalline or polycrystalline cells. There are variety of factors which can boost the higher energy generation among the most critical factors to consider are module mounting height and albedo, or the fraction of light reflected by the surface. Hence, the efficiency of bifacial module for higher energy generation also depends on the reflective behavior of the surface underneath the module and the installation height of the solar power system. An optimal combination of reflective surface and the highest possible system height makes it possible to achieve an additional energy yield of up to 25-30 percent. The increased energy yield and long durability of bifacial glassglass modules contribute to a further reduction in the cost of energy production for all applications.

Bifacial solar modules use direct and reflective sunlight to produce energy from the front and rear surfaces of the module. As a result, they achieve a higher yield. Until now, bifacial technology, which was developed in the 1970s, has had only a small market share due to high production costs. In September 2015, the Institute for Solar Energy Research Hamelin (ISFH) . The bifacial solar cell is a further development of the highperformance PERC cell. In contrast to the PERC cell, the bifacial solar cell has an opening in the screen-printed rear contact to allow light to reach the active region of the cell from the back. The fullarea aluminum printing of the PERC cell has been replaced with an optimized grid, similar to the front contact. Bifacial solar cells have the advantage of producing more energy by using reflective incidental light from the rear along with light from the front of the module. With the transparent rear sides, glass-glass modules therefore provide the ideal module technology for bifacial solar cells. A second glass plate on the rear of the module allows reflected sunlight to reach the cells from the back. In this way, individual modules generate higher yields. Embedding the cells in a glass composite protects them from environmental and mechanical influences. High durability and minimal degradation ensure a maximum service life. The new bifacial product profits from a mature technological process. The transparent and active rear side of bifacial modules enables additional energy production. The “energy boost� of a bifacial PV system describes the increase in specific energy yield (kWh/kWp) of the bifacial module compared with a monofacial module in the same system. Direct or diffused light is reflected from the ground and a portion is scattered to the rear of the module. The amount of light that reaches the rear side largely depends on two factors: the albedo of the ground and the installation height of the module. Researchers and module manufacturers have been developing bifacial cell and module technology for decades. The new process for manufacturing bifacial solar cells based on the PERC technology makes the bifacial cell technology more cost-effective and suitable for industrial production. The bifacial module of this new generation, is available as a glass module with 60 bifacial cells or a glass/clear backsheet module with 72 bifacial cells generating power on both sides and additional energy yield. The size of this increase depends mainly on the reflective behavior of the surface underneath the module and the installation height of the solar power system. An optimal combination of reflective surface and the highest possible system height makes it possible to achieve an additional energy yield of up to 25 percent. The increased energy yield and long durability of bifacial glass-glass modules contribute to a further reduction in the cost of energy production for all applications.

CAN SOLAR AND STORAGE BEAT COAL IN INDIA ?
MS. MONIKA RATHI Head Business Development EPC India & SEA markets Mahindra Susten
Solar Generation Costs with a minimum tariff of 2. 44 Rs/unit have already made solar during the daytime cheaper than the coal plants. If the Sun was shining for the entire 24 hrs and modules generating power for the same time, Solar would have been the choice of energy. However, it is the intermittent nature of renewable power due to which coal has still been the preferred choice for Round the Clock Power. This is however set to change with disruption coming in from the combination of solar and storage solutions. The way technology moved from CRT to LED based displays, film-based camera to Digital camera, typewriters to computers & printers, similar disruption has been seeded into the Indian energy market. The successful completion of Peak Power tender 1200MW/ 3000 MWh by SECI for the world’ s largest renewable with energy storage bid has yielded tariffs which are far lower than expected. Greenko emerged as the lowest bidder with weighted average tariff of ₹ 4. 04/kWh considering pumped storage and Renew with battery storage has won the tender at weighted average of ₹ 4. 30 per unit. The uniqueness of the tender is the assured supply of 600 MW of clean power for 6 hours daily during peak demand hours. The requirement of electricity supply during Peak Hours is to be mandatorily met on a day-to-day basis thereby meeting the requirement of DISCOMS for firm, predictable power.
MR. ASHISH SINGLA Energy Markets Manager – Power ICF
The answer to this question may not be as simple as it is dependent on a number of factors like Battery Energy Storage Systems (BESS) prices, cost of solar generation, firming-up ratio for Solar, type of coal plant being competed against, feedback response on global coal prices due to reduced demand, coal sector deregulation and environmental considerations. All these issues are quite tricky and difficult to make appropriate judgement. A scenario-based approach might be able to provide us some useful insights.
With this, thermal power is set to see the settling days, while the sun will shine brighter. Even, the most recent thermal power tenders in the country have resulted in levelized tariffs in the range of Rs. 5. 007. 00/kWh @ 85% annual PLF, thereby giving an edge to this peak power tender. The improvements in storage technology has been at the forefront leading to this change. Batteries, Flywheel solutions, Pumped Storage, Thermal storage , all technologies have seen improvement over the last few years. The improvements have been in terms of higher efficiencies, lower costs & optimized ways to manage charge/discharge cycles. This in turn has resulted in longer life cycles, thereby making the technology attractive. The biggest development has been in the field of batteries, specially Lithium-ion (Li-ion) and Nickel metal hydride (NiMeH), which has also been fueled by demand in the electric vehicle and transport segment. The battery prices have fallen from ~400 $/kWh in 2015 to lower than 200$/kWh in 2019. The volumes anticipated for batteries in the electric vehicle segment is bound to bring the prices further down. This will usher a new era for renewable energy, bringing radical changes to the way batteries will be used for renewable integration, meet peak requirements, help in frequency regulation, peak shaving and load leveling. The effects of the same are already seen with many such battery-based tenders on rise within India. Some tenders floated are by SECI for Andaman, Leh, Kaza and NTPC for Port Blair.
The improvements in storage technology has been at the forefront leading to this change. Renewable integration with storage technologies has provided the right impetus India needs to reach its ambitious target of having 450 GW of renewable energy by 2030. The renewable with storage wave is unstoppable !!
Currently, the situation in India is slightly different where domestic coal prices continue to be highly regulated and substantially lower than market prices. Coal India Limited (CIL) which supplies nearly 90% of coal to power sector continues to enjoy endless subsidies (direct and indirect) from the Government. This has led to CIL keeping prices low despite increasing costs (direct and indirect) of extraction. However, for India it’ s just a matter of time as domestic coal prices continue to increase. A scenario analysis (shown in the graph below) indicates that solar plus BESS will be able to replace coal plants based on regulated prices (for reliable base-load operations) anywhere between 2040 to 2045 and will be able to beat coal plants based on imported coal prices or de-regulated coal (if current price levels of international coal were to be maintained) between 2030 to 2035.
Figure 1: LCOE (Total cost) comparison between Coal and 'Solar + Storage' (source: ICF analysis)
Globally, the power systems are benefitting from falling storage prices making BESS solutions viable for providing short-duration grid services (primarily ancillary services). Further, recent SECI tenders (for firm peak power supply for 6 hours pre-defined period in a day) have also indicated that storage is becoming increasingly competitive (on energy side as well) with respect to conventional generation capacities. The average peak power tariff quoted by winning bidders (with chemical storage) was INR 6. 85/kWh. These trends are expected to get stronger in the coming years as BESS prices are expected to fall further. Most of the publicly available forecasts (like Lazard, IFC and BNEF) indicate rapid drop in Battery costs (esp. of Li-ion) in the next five years. BloombergNEF (BNEF) forecasts battery costs in U. S. to fall from 176 USD/kWh to 94 USD/kWh (2019 to 2024 period). ICF’ s internal analysis indicates that the cost decline is expected to be driven by a number of factors like growing market for consumer electronics, demand for electric vehicles, improvement in manufacturing processes, economies of scale (GW factories), lower cost of associated components, and advancements in electrolyte technology.
The graph above shows LCOE (Levelized Cost of Energy) range of ‘ Solar + Battery’ for various levels of ‘ firmness’ (from 0% to 60%). Firmness level of 0% represents a solar plant with ‘ zero battery capacity’ tied to it, while firmness level of 60% represents a ‘ Solar + Battery’ plant with battery size which can store 60% of total daily solar generation (and re-supply when required within 24 hours). For 1 MW solar plant with average daily PLF of 20%, a battery size of ~3. 54 MWh represents firmness level of 60%.
Many big utilities in the U. S. (like PacificCorp and NextEra Energy) are realizing benefits of ‘ early coal retirements’ and promoting use of Renewables with Storage to meet the demand.
Acceleration of environmental related costs and installation of other emission controls on coal generation supply chain will only hasten the path towards cost parity between coal and solar+BESS.

WHAT ROLE WILL ENERGY STORAGE PLAY IN SOLAR UTILITY PROJECTS IN FUTURE?
MR. SIMARPREET SINGH
MR. MANJESH NAYAK

Traditionally, energy storage has been limited to off-grid solar, but now its role extends to large utility-scale projects and grid-interactive projects as well. The India Energy Storage Alliance (IESA) has estimated a 70-GW market potential for energy storage by 2022, and this includes mega projects like solar parks as well. In fact, a large proportion of the Indian energy storage market pie will come from solar parks. Energy storage is expected to be an integral part of these projects. While installing energy storage systems for large solar projects requires huge investments, energy storage costs have declined sharply in recent years, and the downward trend is likely to continue, making energy storage solutions an ideal way to deal with the intermittent nature of solar energy and reduce congestion. While the T&D infrastructure for solar power is designed to withstand peak loads, the inconsistency in flow leaves the potential grossly underutilised and makes power systems prone to breakdowns and volatile fluctuations. This may be a bigger issue for larger solar projects, potentially leading to problems during peak usage. The problem can be overcome with energy storage solutions. Moreover, as many large solar facilities are in remote locations like deserts where grid infrastructure does not exist, we need to find a viable way to connect to and store solar energy. With the US and some European countries working on solar batteries for large solar projects, we may have better solutions in a couple of years. The heavy deployment of solar power will necessitate policy decisions to minimise the impact of intermittency and enable grid integration of solar projects. This is where energy storage will come into play and do away with the need for pumping massive investments on upgrading transmission lines to evacuate electricity from mega solar projects. According to the cost estimates from the first phase of Green Energy Corridors, the cost for building a 1-MW transmission system is more than Rs 1 crore. In contrast, large-scale energy storage systems will work out to be much cheaper. The National Electricity Plan amply highlights the role of large-scale energy storage in maintaining grid security, optimising generation, controlling intermittent generation from solar power, ensuring reliable operation of power systems and storing excess generation. Taking into account that utility-scale projects will need to store at least 10% of their daily generation, storage forms about 25% of the cost of a project. As this cost is projected to come down to less than half in the next few years, energy storage solutions are poised to become an integral part of mega projects. The Power Grid Corporation is successfully operating large-scale storage projects in the country. Even the Solar Energy Corporation of India has invited bids for 3. 6 GWh of storage connected to 1. 2 GW of solar in the interstate transmission system. Foreseeing the need for grid scale storage, the Ministry of New and Renewable Energy has launched multiple pilot projects. The most promising of them is a tender recently floated by the NTPC, inviting bids for 625 MW of Solar PV with 100-MWh storage in Andhra Pradesh. While the Indian energy storage market witnessed a demand of 23 GWh in 2018, during 2019-2025 the cumulative potential for energy storage in behind-the-meter and grid-side applications is estimated to be about 190 GWh, according to the India Energy Storage Alliance.
SOLARQUARTER | MARCH ISSUE 2020
India recently concluded what is hailed as the world’ s largest renewablesplus-energy-storage capacity tender – a tender for 1. 2 GW of Renewable Energy (RE) capacity with assured power supply during six hours of peak demand (i. e. 05: 30 – 09: 30 hrs and 17: 30 – 00: 30 hrs). With the climate crisis becoming more and more evident and conventional sources of electricity becoming costlier, consumers are increasingly shifting towards renewable sources of energy. However, the renewable energy sources like solar are intermittent in nature meaning they are not available continuously for conversion to electricity. Hence, electricity storage has become a major focus of attention. Electricity cannot by itself be stored on any scale, but it can be converted to other forms of energy which can be stored and later reconverted to electricity on demand. Over time various electricity storage systems have been developed including Pumped Hydro Storage, Battery systems, Flywheel, Compressed Air Energy Storage, etc of which Pumped Hydro and Battery storage are commonly used technologies. Pumped Hydro Storage has been used since the 1920s and as of 2016, it amounted to about 95% of the world’ s large-scale electricity storage. It involves pumping water uphill to a reservoir from which it can be released on demand to generate hydro-electricity. Pumped storage systems are typically over 100 megawatt hours (MWh) stored energy and are deployed on a large scale. On the battery technology front, the cost of storage has come down drastically. Lithium Ion (Li-ion) Battery costs have reduced by about twothirds between 2000 to 2015. Battery storage technology has helped create smart grids. A smart grid is a power grid which optimises power supply by using information on both supply and demand by using networked control functions of devices with communication capabilities like the smart meters. On household levels and even commercial and Industrial scales, battery storage helps to even out the peak hour demand independent of the grid as well as cater to power requirements during grid outage. Hybridising solar with battery and adopting newer technologies go a long way in customizing the solar plus storage systems to meet customer requirements. One such technology is the Grid sharing Solar inverter by Oorjan Cleantech that helps to compensate for the difference of power from the Utility grid (without discharging the batteries). Large Li-ion storage systems like the 129 MWh system installed by Tesla in the Australia and the recently concluded 1. 2 GW RE with storage tender by the Solar Energy Corporation of India are welcome steps towards the ultimate goal of shifting completely to renewable sources. Cheaper Storage options and evolving technology would make it more efficient and cost effective to generate and consume electricity from Solar and other RE sources.
Over time various electricity storage systems have been developed including Pumped Hydro Storage, Battery systems, Flywheel, Compressed Air Energy Storage, etc of which Pumped Hydro and Battery storage are commonly used technologies.
