“We Are The Distributors For High Quality And High Performance Solar Brands Including Huawei, Longi Solar, Rec, Hoymiles, Leoni And Qc Solar”

0
In Conversation with Mr. Brinder Gandhi, Chief Executive Officer, Impulse Green Energy

How has been Impulse Green Energy’s journey so far and what is its current scale of operations?

Impulse started operations around three years ago as a distributor of solar power equipment. We are the distributors for high quality and high performance solar brands including Huawei, LONGi Solar, REC, Hoymiles, Leoni and QC Solar.

In terms of growth in operations, we had a turnover of only about Rs 7 million in 2016-17 but last year, in 2018-19, our turnover was Rs 360 million. This year, in 2019-20, we are expecting to cross Rs 750 million in turnover. This also reflects the growth of the solar power industry in the country as well as the opportunities for good quality equipment manufacturers. The brands we are working with launched their products in the Indian market around the same time when we entered the market. The growth in our bottom line reflects how the strength of their product has increased over these years. The good quality can be gauged from the fact that we have had several repeat customers for these products.

When we talk about the share of inverters and modules, so far the majority of our revenue was from inverters. Here it must be noted that the cost of modules per MW is eight to ten times the inverter cost but we added modules to our portfolio only last year when we started distributing REC modules. LONGi Solar signed us up in 2019 so this year onwards we are expecting the share of modules in our total revenues to be 50 per cent.

What is the split between rooftop and utility-scale solar space?

Majority of our clients are sourcing the products for rooftop projects. So over 70 per cent of our revenue is derived from rooftop segment and remaining from utility-scale projects. Within rooftop, majority of the business is coming from the commercial and industrial (C&I) segment followed by SECI-sponsored government and institutional users. Residential rooftop has only started picking up recently and is expected to gain traction in the coming years.

Why would project developers source equipment from a distributor and not directly from the manufacturer?

Project developers opt for distributor mostly in the rooftop segment. In the utility-scale market, there is negligible scope for distributor due to the scale of projects. A distributor comes into picture when there is a small expansion or addition in the plant which is to be done in a short span of time.

Moreover, rooftop projects are widely spread across. The cost of supplying to such staggered and distributed projects for companies like LONGi and Huawei is similar to the cost of supplying to any large utility-scale projects. For multinational companies like Huawei and LONGi Solar as well, shipping products to a single company will be much more convenient than shipping to multiple small-scale players. A small rooftop project owner or developer would not want to bear such high costs. Moreover, a single glitch in the process can risk delaying the shipment leading to serious cost implications. In order to avoid the same, it is better to have a channel partner which will support the customer by ensuring that the shipment reaches in time. We maintain adequate stock in order to meet the immediate door delivery requests as well besides being the local and reliable point of contact to address any issues.

How does the after sales service function in this case?

Impulse has its own team of after sales service. The team is trained by our vendors. But this is mostly relevant for inverters as the after sale service for modules is negligible. The only challenge with solar modules is that they need to be handled carefully while being transported and we take full guarantee for the same.

Besides, we are planning to train our local service team to be well versed with various types of defects in modules and also provide them training to have onsite analysis capabilities. This is important to provide the customer quick support and opinion since the sites are staggered and at the company representative may sometime take longer duration to reach the site. However, in case of module defect, nothing can be finalised until the site is analysed by the manufacturer’s team.

What all new module technologies has LONGi Solar brought in the Indian market?

We started with supplying LONGi Solar’s Monocrystalline PERC modules. The company has recently diversified into Monocrystalline PERC half-cut technology which offers significantly better performance and efficiency. The company is now planning to offer higher capacity modules. Currently, they are offering 375 Wp modules which they plan to increase the module capacity to 420 Wp while keeping the dimension/size similar. This will be beneficial for C&I users which have limited rooftop space. A higher capacity module will make a significant difference when seen from a 25-year project lifecycle point of view.

Besides, LONGi Solar is also working on the bifacial technology which is suited for both utility and rooftop solar projects. The technology trials have already begun but we are yet to supply these modules. A number of our customers have shown interest for bifacial technology as the difference in power generation using bifacial modules ranges from 7 per cent to 39 per cent, depending on the surface. For instance, if the modules are installed on a snow covered surface, the reflection levels are significantly high and so is the efficiency. In case of a rooftop, the surface of the roof can be painted white to derive the maximum efficiency from bifacial modules.

The shift from polycrystalline to monocrystalline is already taking place and going forward, we are likely to witness the shift towards bifacial. The transition is inevitable given that the cost differential is not very significant. It will be an increase of only 7 to 8 per cent in cost terms but efficiency gains will be much higher.

How do these products compare with the competing products in the market which may come at a much lower price?

We are only dealing in premium products as our intent is to supply equipment for a project which can be sustainable for a period of 20-25 years. As far as pricing is concerned, products offered by companies like Huawei, LONGi Solar and REC may come at a 4-5 per cent higher price but the value proposition they offer are much more significant.

We try to convince the customer basis the long-term value, good quality and higher efficiency of the product for which they are willing to pay the premium.

Before associating with brands we have analysed the trust factor, the financial strength and the longevity of the brand and all our brands though they demand premium over prevailing market terms are the leaders in technology & innovation, along with being very reputable and recognised brands not only in India but international market too

Which industry verticals are witnessing a greater movement towards solar power?

All industries where power consumption is high are moving towards to solar power. Manufacturing industry including automotive, automobiles, pharmaceuticals, textiles and data centres, is emerging as one of the highest installers of solar power projects.

Large educational institutes are moving towards solar due the benefits offered under the net metering policy in most states. Breweries, distilleries, stone quarries and cement units are going for solar largely due to their RPO obligations. But the trend of moving towards solar is more in the mid-scale owner driven manufacturing units.

What is the company’s geographical reach? Which states are experiencing higher demand for your products?

We are a pan-India player. Headquartered in Mumbai, we have offices in Pune, Bangalore, Hyderabad and Delhi. Our warehouses are in Navi Mumbai, Chennai and Ajmer. This is sufficient to cater to the central, western, northern and southern regions. We are now beginning to see demand from the eastern region as well. So we are planning to hire more people in the eastern regions.

In order to optimise costs, we are also taking the channel partner route. For instance, we have a channel partner in Rajasthan wherein we provide them a complete container of modules and inverters for supply within the state.

We are witnessing high demand in Maharashtra, Rajasthan, Andhra Pradesh, Gujarat, Telangana, Tamil Nadu and Karnataka. We are also beginning to witness activity in Haryana and Uttar Pradesh besides the eastern region.

What are the best practices for efficient and safe logistics of modules and inverters?

Inverters are much easier to transport compared to modules which are extremely fragile. We take guarantee for proper shipment of modules till the customer’s premises. If broken or damaged during the transfer, we either replace the module or provide refund. Proper packing of modules is crucial to ensure that they do not get damaged, especially if they are transported to remote locations for which the approach roads are generally of poor quality.

Therefore, special attention is paid towards packing and we have specifically trained our warehouse team to pack modules in such manner so that they can last the journey on Indian roads. This type of packing is important not only to avoid breakages but to avoid micro cracks too. We are also open to ideas from our partners who suggest new ways. Further, our team keeps an eye on the most effective and cost efficient processes of packing so that we can make the process fool proof.

What are the new technologies or products that customers of solar power projects can expect in 2019-20?

Mono PERC is the latest and most trending technology currently. The emphasis in the coming year would be on increasing efficiencies and watt-class in this technology by using half cut platform.

Bifacial modules are going to be the next big thing in the solar panel space in India. LONGi Solar has already released its bifacial PERC monocrystalline module and we are soon going to start supplying these as customers are showing interest in higher efficiency products.

In the inverter space, micro inverters, which are already available in the market, are going to be our next offering. While Huawei currently offers string solutions with optimisers for the rooftop customers in India, it is already selling micro inverters in the European markets where they are a big hit. But very soon, we are going to start supplying these in India as soon as the residential rooftop, which will have much smaller-scale projects, starts gaining traction.

As Solar storage is the current buzzword in the solar industry and Raychem RPG being the pioneer in this segment, what would be the demand outlook for the storage products in 2019?

Year 2019 is turning out to be the transformational year for energy storage and solar segments. There are three key levers that are working together to create and integrate energy storage with solar markets in India

a. Government Policies – Government has come out with FAME-2 for electric mobility, as well as, the Energy Storage Mission and CERC amendment for demand side management for utilities. It is also working with utilities for adoption of future business model along with focus on overall improvement of utility’s financials. Many pilot and demonstration projects are planned to set the base for long term business model for industry players and developers

b. Market Dynamics – Growing adoption of energy storage globally has demonstrated that it is not limited to just one application. The dispatchable power along with multitude of use cases can create business models for developers and utilities to push for hybrid solar + storage or RE + storage projects

c. Technology Maturity – There have been several projects globally to demonstrate the actual working of energy storage system with the grid and load sub-systems that gives relevant data points for developers to contain their risk and build credible business models.

Another important factor is that the Battery production is attaining economies of scale leading into supply chain stabilization and passing on the benefits to the customers.

Raychem RPG has done Strategic Technology Partnership with various companies. Can you tell us more about this?

Raychem RPG has done technology collaboration with Dynapower, a global leader in energy storage products and technologies with over 500+ MW of storage projects deployed globally. Raychem RPG collaboration with Dynapower addresses three major areas:

a. Manufacturing of power conversion systems in India – These products are customized and stabilized for Indian environment while ensuring global standards.

Raychem RPG has a fairly well evolved 3R concept for customer service – Reliable, Responsive and Receptive. The company has Pan-India service presence to ensure that customers get First Time Right Service with complete life cycle promise for their investments.

Raychem RPG is also one of the very few companies to have attained excellence level of TPM that ensures that all the products manufactured and/or supplied by us are quality products and delivered to customer sites on time.

How the solar industry will evolve in the next 2 years?

Renewable energy is showing growing adoption globally and the next frontier is dispatchable renewable energy that is driving the growing adoption of energy storage. Renewable percentage of the overall energy consumption will keep showing the upward trend. We also see that the consumers will start driving further adoption of Green energy.

Utilities across the world are remodelling their business models to become more service oriented and giving options to consumers to drive new energy consumption patterns. Energy as a domain and infrastructure is expected to evolve at break-neck speed in the next two years and keep all major players in the domain on their toes.

“We Have To Continuously Enhance Our Quality And Adopt Latest Technologies So We Are Not Focusing On EPC Or Tenders Business”

0
In Conversation with Mr. Vikas Jain, Director, Insolation Energy P. Ltd.

Could you give our readers a brief introduction of your company?

Insolation Energy is being Promoted by Vikas Jain & Manish Gupta both are Engineers from Education Background and company was incorporated in 2016.

We begun our commercial production from year 2017 April with an Fully automatic line of capacity 80 MW. It is one of the most advanced plant installed in North India having manufacturing base in Jaipur on NH8.

What are the services provided by your company? What makes you stand apart from other players in the market?

We are purely into Panels Manufacturing keeping our complete focus on manufacturing only. WE believe still there is lot of R&D going on in this field and we have to continuously enhance our quality and adopt latest technologies so we are not focusing on EPC or tenders business.

What according to you has been the biggest milestone on your path?

The decision to invest in good equipment and selection of right team has been biggest milestone without which we would not be able to reach at this positon. At the start of plant we got an order for 2.3 MW plant in Ujjain were we could prove our quality and this was the biggest milestone in our growth.

As a module manufacturer, what trend do you expect in the race in Module Technology?

New trends are Twin Peak / Bifacial and Mono PERC. We have already started making MONO PERC modules and are In process of quality updation for Bifacial and Twin Peak Modules.

Module Quality, Costs, and Performance are key concern areas for Indian project developers. How would you like to address these issues for your offerings in India?

There is too much pressure in India on the cost of solar Modules we strive hard to keep our prices competitive without any compromise in quality. Since last two years we have been able to supply good quality panels in market and customers are gaining confidence in our quality and we have receving repeat orders from the satisfied customers now. In the past it has been observed that some Chinese companies failed to provide warranty claims and replacement to indian EPC companies .Since we are a local company we can address their concerns better.

What are your plans for the current and next financial year?

India has been our biggest market as of now but we trying very hard to reach markets of Middle East Africa and Latin America. We hope to get some good orders from these countries in near future.

Currently our capacity is 80 MW per Annum we are going to make the size double in this fiscal alongwith modules we are also planning for a cell line and a Lithium batter line. This year we plan to do a business of 100 cr. We have target of atleast 25% growth YoY.

“We Are Committed To Bring Latest Technologies & Greater Efficiency Solar Modules To Reduce LCOE On All Solar Projects”

0
In Conversation with Mr. Prashant Mathur, CMO, Adani Solar

You are a global leader in the solar industry. Could you please tell us about your current business presence in India?

 Adani Solar is the Solar PV manufacturing arm of Adani Group, one of India’s largest businesses spanning across Resources. Logistics, Energy, Agri and ancillary industries. Our company is the largest & only vertically integrated cell & module manufacturer in India with 1.2 GW capacity. We continue to increase our presence with large EPC & medium EPC –that continues to be our bread & butter segment. Apart from that we are focused on expanding our retail presence/ footprints. We have channel partners all over India, through which we are now going deeper in to the market and becoming the choice of our consumer who would demand Adani Solar modules from their EPC companies, so in terms of brand visibility Adani Solar is now getting deeper in to the rural market as well as the last mile connectivity with the customers.

Tell us more about the latest innovations in your product and solution offerings for the Indian market.

We continue to make innovations in our products, with greater efficiency and bringing latest products in the global market. Bifacial and half-cut cells, N heterojunction, Multi bus bars etc. and the kind of technologies we will bring to India that is gaining popularity globally. To mention a few, in multi-crystalline modules we continue to produce highest Wattage modules of 335 – 345 Wp, in MonoPERC series of modules of 365 – 380 Wattages and we also have Bifacial modules, though in India Bifacial modules are not popular, but we feel that in future Bifacial will become more popular.

 What exciting opportunities do you see in the Indian and global markets?

 I think solar has now taken the pace which we envisioned several years way back, that brought us into solar manufacturing. Now the cost of developing solar energy is so low that more people are adapting to solar energy that gives us a whole new canvas in India, like we see opportunities on the Rooftop. In terms of penetration, the rooftop segment is less explored compared to Utility and ground mount projects. In future, more roofs will be solar powered. Rooftop solar will become more popular and that’s going to be a driving force for India. Globally solar is now no longer a developed nation’s commodity, it is now getting popular in Far East countries and more developing countries are now adapting solar. Many projects and opportunities happening now in Middle East countries, Africa, South America which never had solar earlier, are now realizing that solar is very competitive and it produces clean energy. Globally now solar has arrived, and that is what we see opportunities everywhere.

Would you be focusing on international/ export market. If so, how different is Indian PV module market from the International market?

Now Indian PV Market is evolving at a faster pace. Earlier it was a price sensitive market, as the customer would not realize that the product which they bought may perform or not, because a mediocre product will stop generating power after few or prolonged usage. Quality, Brand & the supplier credentials are now becoming more important. People are now paying that extra to get that better quality from reliable suppliers. So a lot of this has changed that was never there in Indian market. In International market, the customers were well aware of the importance of quality and the manufacturers background, which is now being considered important in India as well.

With a growing competition from Indian as well as global companies, is there sufficient demand in India to match the supply? At times, Indian demand actually outmatches the supply, so I think there is a huge demand in India, it will continue to grow. Now with customers getting more aware, they are realizing the importance and prefer to buy products from Indian manufacturers who will stand with the product if there is any issue. At least they will be sure who the supplier is? What will be the warranty and how will be the after sales support? Global competition is good; because that drives and motivates us to be on our toes, by bringing the best products at the best competitive price. But there is no dearth of demand in India with the government policies in favor of solar, this will go up indeed.

Please could you shed some light on your plans for India over the next 12 months?

We are targeting to elevate Wattage peaks in our modules. For Multi-crystalline modules at 345-355 Wp. With the Mono PERC we are targeting to hit 380-390 Wp in the next 6 months and with the half cut technology we are targeting to deliver 390-400 Wp in the next 6 months’ time period. We are working on new technologies which will get us to more than 400 Wp in the next 12 months’ time period.

We see trend is now moving towards Mono PERC and there are good prospects for products such as Multi bus bar, heterojunction and half cut cell modules in the near future. It should be noted that we are the only manufacturer in India to produce high efficiency monofacial and bifacial modules. We are confident of boosting these efficiencies. Our objective is to achieve a capacity of above 400 Wp modules in the next 6 to 8 months.

What technical advantages Adani Solar providers to their consumer?

Since inception of Adani Solar, we have been the early adopters in the production and manufacturing technology. Adani Solar is India’s first vertically integrated business that offers products along with services across the spectrum of photovoltaic manufacturing and yes going forward, we will convert greater capacity from Multi to Mono depending on LCOE trends.

PV Industry is seeing some interesting changes on the PERC, PERT, HJT, TopCon manufacturing where multiple manufacturers are trying new technologies. There are certain technologies that offer very high wattages but that do not support the LCOE benefits at current market conditions due to high input cost. Economy of scale should be driving costs lower and we at Adani Solar are geared to meet the LCOE roadmap.

Adani has been awarded as the most Reliable PV module manufacturer. How would you like to keep the momentum?

After achieving Top Performer ratings during early June 2019 in terms of performance & reliability among all its industry peers in the PVEL scorecard report for two consecutive years 2018 & 2019, Adani Solar emerged as the only Indian manufacturer considered as a bankable company for projects outside India, ahead of many other Indian solar manufacturers in terms of brand recognition.

We honor and acknowledge such accomplishments and ratings from globally renowned bodies like PVEL and BNEF. In solar Industry, vertically integrated manufacturers like Adani Solar are more often considered bankable than non-vertically integrated ones as they have both control over process and quality. Such accreditations demonstrate that Adani Solar is a committed manufacturer which has implemented state-of-the-art facility with best industry practices ensuring superior performance and reliability of its products.

Quality, Costs and Performance are key concern areas for Indian project developers. How would you like to address these issues for your offerings in India?

I think solar modules are already at their lowest in terms of pricing, we don’t see it moving up and down by more than 4 to 5 % in the next few years, but the cost of ownership of the projects built will continue to go down and not by a big margin, because the module prices won’t go down but high efficiencies modules will become more popular, that’ll drive the balance of system costs lower, so we still see that the project cost overall will go down, which will make projects viable. So our offerings will be to give the best quality product at the most competitive price and to stand with the product performance and after sales service that is going to be our USP coming from a well-diversified group.

What differentiates your company’s offerings from your peers?

I think the most important offering for any module manufacturer is the reliability, i.e. product reliability and company’s reliability. With Adani Solar you get both, as we manufacture cells and modules in house, we are also looking to set up wafer and ingot facility, which will be one-of-its-kind in India. We are bringing the best quality product along with the reliability associated with the Group. That is our differentiating factor from other manufacturers who are only dependent on solar business.

In Conversation with Mr. Nikunj Patel, Founder & CEO, Australian Premium Solar (India) Pvt. Ltd

Could you please tell us about Australian premium solar presence in India?

We are present in India since 2013. We began our operation in India only as solar module manufacturers, having annual production capacity of 20 MW. And now, after 6 years of dedication and hard work, we have grown into one of the fastest growing solar solution provider company which includes the roles of solar module manufacturing and solar inverter supply. We have been supplying our modules and inverters pan India. We aim to become one of the largest solar energy solution providers of India through our insatiable hunger for top quality of products and services.

Kindly give us an insight on Australian premium solar (APS) product portfolio along with the service offering for the Indian market?

We are offering solar energy products with bigger ranges and better warranties. We are offering solar modules ranging from 40 Wp to 350 Wp. We are also conducting a trial run of our own brand of inverters with 500 of our current customers since last 6 months, and till now they all seem to be pretty satisfied with its performance. So, now we are introducing it in this year’s REI. We are offering a range of 1 KW to 80 KW for inverters to fulfil residential, commercial, institutional and commercial requirements. Along with this we are also supplying other top brands of inverters as per the customer requirements as well.

What differentiates your company’s offering from your competitors?

We have seen a trend in the Indian market that most of the large scale system integrators are coming from a manufacturing background. Whereas, we have been working as system installers/integrators since more than a decade in Australia. So, we are well aware of the issues faced by the integrators, and we have kept our R&D focused accordingly and we are manufacturing modules and supplying inverters keeping those things in mind. So, that experience becomes very handy when we are bringing in something new or when we are providing after-sale service. That is where we are different from our competitors. We offer better warranty and better quality at most competitive prices. Most of our customers are affiliated with us for a longer time period, majorly because of the quality of product as well as the after-sale service. We are different because we know all the aspects of the work we are doing, let it be R&D or manufacturing. The other major difference is that we are providing products for wide range, from residential to utility, and we also provide all major components, making us a one stop solution for installers as well as end users.

Could you please shed some light on Australian premium solar’s desirable target for the year 2019-2020?

This is something which has been our strength. We always have a very clear picture about in which direction we are heading. Right now we are standing at 100 MW of annual production, and we are looking forward to making it 250 MW. The company started in 2008 with Just 4500 AUD, and from there, in 11 years, we have grown to become one of the largest solar energy company in Australia, and have grown to achieve a cumulative turnover of more than INR 600 Cr. From our group of companies. We have been following one simple strategy of doubling the turn over each year, and till now it has worked perfectly for us. For India we have a target of achieving turnover of INR 200 Cr by the end of year 2020.

Trina Solar Surpasses 4GW Of Modules In India

0

Trina Solar, the global leader in photovoltaic and smart energy solutions, has become the first PV manufacturer to have a total of more than 4GW of modules in India.

Gaurav Mathur, Trina Solar’s India director attributes the achievement to: “Trina Solar’s technical expertise, strong local market knowledge and relationships.”

“We have come far, from shipping under 15MW of solar modules for the whole of 2010, our first year in India, to shipping a record 700MW in just one quarter of 2017.”

“India has become a major solar market on the world map. India recognizes the value of clean, stable and cost-effective solar energy,” Mathur adds.

He also says: “The 4GW milestone is a testament to the quality of our sales team in India. Our team here is technically sound and also works very hard to provide good customer service and logistics support across all industry segments.”

“We work with developers across the country, although the bigger installations are often in the southern part of the country, in states such as Tamil Nadu and Andhra Pradesh. There are several reasons, why large-scale projects are often in the south, such as availability of affordable land.”

“We are big in solar farms, as utility-scale solar provides stability and low-cost energy for local grids. But we are also doing very unique installations, such as airports and building-integrated photovoltaics,” Mathur says.

Trina Solar has also seen strong growth in the commercial and industrial segment.

Mathur says: “Businesses here are keen, with many from the textile, pharmaceutical, chemical, logistics and IT industries installing 50-500kW rooftop and ground-mount installations. Solar is a sensible choice for businesses as grid electricity can be expensive. Energy-intensive businesses in India are also following respected brands like Walmart and Honda in going solar with us, as they want to reduce their reliance on the local grid, ensuring that communities nearby are not affected by their energy usage.”

He says solar energy is feasible for industrial and commercial businesses in India, because many have a lot of roof space or land available for solar installations.

Some commercial and industrial companies pay to have a solar system, while there are others that sign a long-term electricity use contract with an energy supplier that then pays for the solar system.

Mathur says: “Customers are always price savvy but are also concerned about quality. Owners and financiers of solar installations are looking more to tier-one manufacturers such as Trina Solar because we have the reputation, warranties and bankability ratings.”

“There has been a shake-out in the market where some tier-two solar manufacturers have effectively exited the market,” he adds.

Besides the utility, commercial and industrial segments; Trina Solar is also helping households and small businesses to adopt solar by offering an affordable ‘all in one’ solution, for residential business that includes the solar modules, inverters and mounting system.

Helena Li, Trina Solar president for Asia Pacific and head of global module sales, says Asia Pacific including India is a key market for Trina Solar globally.

The company continues to make inroads into the market by introducing new high-efficiency modules that combine leading industry technologies, she says, adding that the company is also offering smart energy solutions such as TrinaPro, which is an ‘all in one solution’.

“Engie Is The World’s Largest Independent Power Producer (IPP), With More Than 100 Gw In Operation Globally”

0

Engie’s presence in India has been around for over two decades, how has the experience been?

Engie is the world’s largest Independent Power Producer (IPP), with more than 100 GW in operation globally. This includes power generation from all sources like natural gas, hydro, wind, solar, nuclear, coal, biomass & biogas, etc. Engie has a worldwide strategy to promote Low Carbon energy and gradually phase out of activities with the highest levels of CO2 emissions such as coal fired power production. Engie has identified India as a potential country that can contribute in accomplishing its ambition to be a world leader in the transition to zero-carbon emission. Engie Group also provides governments, communities, cities and businesses with efficient and innovative solutions based on its expertise in four key sectors: independent power development, renewable energy, liquefied natural gas and energy efficiency services. ENGIE employs 155,000 people worldwide and is present in 70 countries across 5 continents.

ENGIE has been present in India since more than 20 years, carrying out service activities such as engineering and renewable energy generation. Its total generation capacity now stands at 1.5 GW+, which includes 1GW+ of Solar and 482 MW of Wind. Engie group employs around 1,000 people in India, including power generation development that commenced in 2014, as well as in energy and engineering services, which existed since about two decades.

Engie’s 101MWp solar plant in UP was inaugurated by India’s Prime Minister Mr. Narendra Modi and French President Mr. Emmanuel Macron.

Engie’s experience in India has been encouraging despite challenges encountered by the renewable industry in general. The major challenges faced generally have been around land acquisition, inter-coordination between various governmental agencies, evacuation approvals, etc.

Where do you see the Solar Energy industry in India poised for the next 10 years? What are your growth plans for the Indian market?

With the government initiatives enforced across the country, India is poised to grow rapidly in achieving the target of 175GW of renewable energy by 2022. India has a large potential for renewable energy and the government has set up massive goals for solar power generation.

In the next 10 years, India is set to be one of the largest solar power producers with the generation being used across industries, agriculture, homes, etc. Considering this huge potential, Engie has ambitious plans for India and would aim to be one of the key players in the solar and wind industry in India, as long as the policies and initiatives by the Indian government remain supportive.

India is now producing the world’s cheapest solar power, what are your views on the same?

Healthy competition leads to the growth of the industry. India is an extremely competitive market, and this factor has been the key in shaping the economics of the sector. As long as the pricing in the renewable market can produce power efficiently, without compromising on the quality of the plants, it will continue to be adopted by the industry. We also believe that there should be enforcement of minimum specifications in order to ensure that quality is not comprised while trying to be competitive.

The path forward is to be competitive by using new and innovative technologies to build high-efficiency power plants. Hybrid power plants, battery storage, floating solar plants, etc. are some of the high potential markets in the immediate future. LCOE would be a crucial factor for driving hybrid tenders either with Solar PV + Storage or Solar PV + Wind or all three PV + Wind + Storage together, where PLF can be maximized with optimum capex and opex.

What are your views on the Government policies? Do you think they have brought about the intended benefits?

The Government’s targets are quite ambitious. It has set a target of installing 175 GW of renewable energy capacity by the year 2022, which includes 100 GW from solar, 60 GW from wind, 10 GW from bio-power and 5 GW from small hydropower. This has given impetus for the renewable energy sector to grow rapidly.

In order to achieve this target, various policies and initiatives to promote investment in this market have been introduced. One amongst some of the encouraging policies, is that the Union power ministry has made it mandatory for DISCOMs to open and maintain letters of credit (LCs). This will prove to be a reassuring payment-security mechanism under power purchase agreements (PPAs) signed with generation companies. Another motivating initiative of the government is the recent 20-40 per cent financial subsidy for new residential rooftop solar installations. This will significantly accelerate the pace of such roof-top installations. But what we would really like to see is the alignment of various policies between different Departments of the Government like PGCIL, CEA, SECI and State Agencies, which can smoothen the implementation of projects and can invite more investments into the country.

Technology is moving forward all the time, is there anything that you’re looking forward to seeing happen in the next few years?

Technological innovations and developments are the only way forward for a sustainable market. In the solar industry, various breakthroughs have been achieved to increase the Wp rating and efficiency of the PV modules. There have also been developments in the Inverters, leading to higher power and voltage ratings, higher DC overloading, string inverters suitable for large PV plants, etc. Developments in the tracking technology & robotic dry module cleaning systems, have also been promising. Various innovations are ongoing in the areas of Floating solar, Hybrid and Battery storage projects. Apart from lithium ion batteries, there are many other technologies where experiments are being conducted in the laboratories and expected to hit the commercial market soon. Engie has around 1000 researchers in the world with various labs, with a dedicated lab for lithium ion batteries. Hydrogen as a means of storage is also being studied.

To Improve the grid stability, there has been a lot of emphasis on forecasting & scheduling of the renewable power. Many Innovative solutions for the same are now available in the market and further improvements on many aspects are ongoing.

All these advances are promising as they will lead to improvement in project economies.

Key Parameters Contributing Gain in Bifacial PV Systems

0

The yield gain over conventional monofacial modules is mainly determined by the conversion efficiency for solar irradiance incident on the rear side of a bifacial PV module, and the amount and quality of solar irradiance incident on the rear side. Bifacial modules allow a unique vertical mounting configuration. Various studies indicate that vertically installed bifacial PV modules in higher latitude locations produce energy which is comparable to monofacial modules installed at conventional latitude tilt, and significantly higher than that of vertically mounted monofacial modules.

Below are the major key parameters that contribute to the gain in bifacial PV system:

Albedo is the measure of solar irradiance incident on the rear side. It is defined as the ratio of irradiance reflected to the irradiance received by a surface. Albedo depends on soil surface colour & texture. This require proper soil condition study for its optical properties for uniform gain throughout the year. Hence soil preparation activity is very important for getting maximum gain from bifacial modules. The whiter & smoother is the surface the better is the albedo resulting in higher bifacial gain. It can also vary with seasons like for winter with white snow it is about 90%, for spring with green grass it is around 25%, summer with dry grass accounts to 33% and fall with humid soil gives nearly 15% of gain, hence making snow the best and volcanic rock the worst case for albedo.

Height is another key factor taken into consideration while designing the bifacial modules. Bifacial performance is increased by increasing the height of the installation thereby reducing the shadow intensity projection. According to our study, at the height 0.5m, 0.8m and 1.2m gain obtained is approximately -3%, 5% and 8% respectively, but this gain is limited to certain height. Increasing the height beyond certain height the saturation will set in the gain.

Pitch also plays a vital role in contributing the energy gain. Greater is the pitch, more is the reflected area resulting lower Ground Coverage Ratio (GCR) thus giving higher bifacial energy gain. However, increasing the pitch is not a feasible option as it comes along with issues of land constraints and increasing the total cost of the project. The cost of bifacial modules is about 8% higher over conventional monofacial modules with an advantage of 5-10% gain.

According to bifacial module market share forecast, its deployment is about to be 3% by end of 2018 and the market aims to rise sharply, reaching 40% by 2025. We at Mahindra will be deploying 10-20MW of Bifacial modules by first quarter of 2019 and shall be sharing more insights on Bifacial modules post installation in our upcoming article release.

Solis Launches Utility Inverter Solution at Solar Power International

0

Ginlong Technologies, a global leader in photovoltaic string inverter manufacturing, expands its Solis portfolio with a new utility-scale solution for the U.S. solar market. The Solis 125kW 1500V three-phase string inverter will make its debut at the Solar Power International exhibit Sept. 23 through 26 in Salt Lake City, Utah.

Ground-based PV Plant of solis

According to Bloomberg New Energy Finance’s recent Solar Module and Inverter Bankability report, Solis earned third place among Asian inverter brands out of a total of 17 global inverter manufacturers. Banks are more willing to offer non-recourse loans to PV projects using Solis inverters, helping developers secure financing.

PV asset owners are increasingly turning to string inverter technologies for utility-scale projects. Delivering substantial energy harvest advantages, the Solis 125kW solution combines high power density and light weight to streamline installation. Furthermore, Ginlong’s integrated utility solution includes a dedicated U.S.-based service team to guarantee hassle free O&M.

“Solis continuously sets new standards in string inverter reliability,” says Gary Lam, Head of Utility Business at Ginlong Solis USA. “High system reliability means ultra-low maintenance costs for our customers, boosting returns over the life of their assets.”

DNV-GL validation testing puts Solis at the very top of the performance range for three-phase string inverters. DNV-GL notes “the inverter life models presented are positively impacted by the long and impressive track record of PV inverters designed and manufactured by Ginlong. The useful life projections are at or near the top of the string inverter life projections.”

Designed for higher energy yield, the Solis 125kW offers unique advantages including:
● 33% higher DC string voltage than 1000V systems, resulting in higher energy density and lower installation costs
● 99.1% maximum efficiency — one of the highest in the market
● 20 DC inputs results in DC to AC ratios up to 150% for greater energy generation during lower irradiance conditions
● Optional AC combiner connects two-125kW units into a 250K system, substantially reducing AC cable costs

The Solis 125 kW features built-in string monitoring, which measures all string parameters for quick fault isolation and system commissioning. An integrated smart I/V curve scanning feature helps detect such string faults as panel mismatch and shading, decreasing O&M time and increasing system energy yield. DC fuses on both positive and negative inputs protect the inverter and DC cables, while built-in replicable DC and AC Type II surge protection devices (SPD) safeguard during power surges, further ensuring system availability. Lastly, Type I SPD protection is also available to shield against damage from frequent surges and lightning strikes.

Solis ranked Top 3 among Asian brands

Bloomberg New Energy Finance (BNEF) recently released its Solar Module & Inverter Bankability 2019 report. For the first time, the company made investigations into solar inverters, surveying the bankability of several inverter brands.

BloombergNEF's inverter bankability survey results

‘Bankability’ means banks are more willing to offer non-recourse loans to photovoltaic power generation projects that opt to use a particular inverter brand.

Solis’ inverters ranked third for Asian brands: a testament to the brand’s products being well-recognised by global technical experts and respondents. This incredible result also means project developers are more likely to receive bank financing if they use Solis’ products over those of other brands.

With a team of experts spread across six continents, BNEF analyses complex data from around the globe to procure in-depth forecasts which highlight the financial, economic and political implications of industry-transforming trends and technologies.

For this survey, BNEF sought information from banks, developers and technical due diligence firms about which brands, out of 48 module manufacturers and 17 inverter manufacturers, they considered to be bankable.

Interestingly, regional differences are far starker when considering the bankability of inverters compared to modules. Unlike panels, inverters are less of a commodity as modules have only one function — producing energy — while inverters have multiple purposes. Aside from converting direct current into alternating current, inverters interact directly with the grid and aggregate power output data. As such, there are different types of inverters for different project requirements (for example, some projects require central inverters while string inverters are more suitable for others).

Helios Infrastructure fund projects produce enough power for nearly 4,000 homes

Today, Sol Systems announced that Helios Infrastructure fund, its joint venture with Nationwide, has completed the financing and construction of its first solar portfolio. The entire portfolio is now in service and includes eight projects in North Carolina totaling 48.4 MW, which is enough to power 3,890 homes per year.

These projects are part of a larger 135 MW acquisition announced last September that is currently under development. The acquisition itself is part of a broader set of portfolios the infrastructure fund plans to develop.

Launched in February 2018, Helios invests in utility-scale solar energy assets throughout the United States, combining tax-efficient sponsor capital, highly sophisticated financial structuring and environmental and electricity commodity expertise. Helios works closely with developers throughout the United States to co-develop, finance, and construct early-stage solar portfolios.

“This is a key first step in our efforts to develop a multi-state solar infrastructure portfolio,” said Jessie Robbins, Senior Director of Structured Finance at Sol Systems. “This portfolio was delivered on time and on budget, despite the inevitable challenges along the way. We greatly appreciate our finance and development partners, who worked collaboratively with us to navigate a complex portfolio in an ever-changing market.”

“Live Oak Bank is dedicated to lending to projects that bring jobs, economic benefits and low cost renewable energy generation to America’s rural communities,” said Jennifer Williams, SVP of Renewable Energy at the bank, “and we are excited to be part of this innovative portfolio with Sol Systems, Nationwide, Seminole Financial Services, Cypress Creek Renewables, and U.S. Bank.”

Seminole Financial Services was the construction lender for the projects, U.S. Bank was the tax equity provider, and Live Oak Bank was the permanent lender for the portfolio. Cypress Creek developed and built the eight projects and will provide operations and maintenance support going forward.

“U.S. Bank has a long relationship with Sol Systems and we are excited to partner with Helios on this first portfolio,” said Jon Peeples, vice president with U.S. Bank and business development officer with the U.S. Bancorp Community Development Corp. “Environmental stewardship is important to us and these projects are a great addition to our growing solar portfolio around the United States.”

These solar developments represent a $74.1 million capital investment into rural North Carolina communities. Nearly 400 jobs were created throughout project construction, including 70 local jobs.

Ampt LLC, the world’s #1 DC optimizer company for large-scale photovoltaic (PV) systems, today reported the rapid adoption of their String Optimizer products in large-scale PV solar+storage projects totaling one gigawatt-hour (GWh). Ampt String Optimizers are DC/DC converters that uniquely deliver higher performing solar+storage systems that cost less than solutions without Ampt.

Ampt attributes this recent series of projects to the adaptive technology in its String Optimizers which delivers value in a wide range of system sizes and storage applications. These projects combine solar PV with DC-coupled energy storage. The mix of projects include several PV systems ranging from 50 to 100 megawatts (MW), multiple projects between 10 and 30MW, and numerous 10MW and under projects. The PV-to-battery-to-inverter ratio on these systems range up to 2:1:1 with two- to five-hour charge durations being most common. Project locations in the U.S. include California, Hawaii, Massachusetts, New Jersey, and New York.

Today’s announced project momentum follows another milestone reported earlier this year. In January, Ampt String Optimizers were deployed on a record-breaking PV peaker power plant that has 28MW of solar PV and 100 megawatt-hours (MWh) of DC-coupled energy storage.

“These projects are a testament to the industry’s recognition of the value that both Ampt optimizers and DC-coupled energy storage bring to solar,” said Darryl Parker, Vice President of Sales and Marketing for Ampt.

Including energy storage allows PV systems to provide energy on demand and supports grid stability. DC-coupled energy storage systems charge batteries directly from the DC solar array to achieve a lower cost per megawatt-hour compared to AC-coupled approaches.

“Innovations in energy storage are driving its rapid growth in large-scale PV systems around the world and Ampt’s technology is an example of what can be done to improve economics,” said Levent Gun, CEO of Ampt. “We look forward to continuing to build strong relationships with our partners and customers to increase global renewable energy capacity.”

Ampt String Optimizers harmonize the operation of the PV array and power components with a fixed and high DC bus voltage. This lowers the cost of both the DC/DC battery converters and DC/AC inverters while reducing the amount of wire and other BOS components. Performing string-level maximum power point tracking (MPPT) captures energy from variable module degradation and other sources of mismatch to increase lifetime system performance. This unique feature set delivers lower cost systems that perform better.

Additionally, Ampt optimizers use wireless communications to provide high-accuracy synchronous string-level data to enhance operations and maintenance (O&M) effectiveness.
