“India Has Already Overtaken The Us And Has Become The Second Largest Solar Power Market In The World”

0
  1. Mr. Harjinder Kamboj, Head-Quality Azure talks about future of India’s solar industry and quality parameter that should be maintained.
  2. Where do you see the Solar Energy industry in India poised for the next 10 years?  

Solar Energy Industry is expected to grow at a very fast pace in India owing to majorly four positive factors: 

  1. Robust demand due to good economic growth.
  2. Increasing investment because the sector has become quite attractive for both foreign and domestic investors.
  3. Policy support as Government has ramped-up target to achieve 100GW solar installation by 2022. Hopefully, this trend will continue beyond 2022 as well. 
  4. Competitiveness advantage that India has because of the availability of sunlight throughout the year.   

We have seen that in recent years, growth of solar energy in emerging markets had been phenomenal. India has already overtaken the US and has become the second largest solar power market in the world, in terms of solar power installations. 

The country currently stands at almost 25 GW of grid-connected solar power capacity as compared to 9 GW in 2015. Large scale solar installations in India account for 87 percent of solar capacity while rooftop sector has also picked-up. Last year, solar accounted for nearly 53 percent of new energy capacity additions in the country and this is great news for solar sector.

For a developing country like India, where electricity for every home was once considered a dream is now close to reality. The government initiative of ‘power for all’ is changing the socio-economic structure of the country. In fact, people are demand 24×7 power supply and Government is also working tirelessly to fulfil their demand.

The sector also has immense potential to create new jobs; 1 GW of Solar manufacturing facility generates approximately 4000 direct and indirect jobs. In addition, solar deployment, operations and maintenance creates additional recurring jobs in the sector.

Are we seeing a major push towards better & smarter technology in solar sector by the EPC contractors? 

With power tariff hitting all time low, developers are under tremendous pressure on cost. So, at present, more focus is on reduction of project cost per KWp, while maintaining quality of equipment and construction at the same level.  

However, a lot of developments have been seen in this regard, like; 

  • Development and use of new construction machinery and tools for a quick project handling. 
  • Optimization of efficiency and reliability of photovoltaic systems.
  • Use of String Inverters rather than Central Inverters in order to minimise the mis-match losses and to maximise the output.  
  • R&D of utility-scale energy storage systems for stabilization of regional power grids. 
  • Combination of Wind, Solar and even fuel-based energy sources in Hybrid Power Plants.
  • Co-operation with energy suppliers and grid operators for an utmost environmentally-friendly and inexhaustible source of energy. 
  • Remote installation monitoring by drone-based system.

Solar project should be designed for a life of 25 years. What quality parameters should mounting structures adhere to, in order to sustain over this period?  

Solar Mounting Structures are critical components in solar power plants, which support the solar panels on the ground or on rooftops. They ensure the structural stability of the solar system.

Solar panels need secure fastening to the roof or ground to protect against high velocity winds. Moreover, solar panels also require protection against water logging and other elements that gather on the ground or on the roof. Mounting structures must adhere to adverse environment conditions. 

The Mounting structure shall be so designed to withstand the speed for the wind zone of the location where a PV system is proposed to be installed. 

It may be ensured that the design has been certified by a recognized Lab / Institution and submit Wind Load calculation sheet to MEDA. 

Suitable fastening arrangement and grouting should be provided in order to secure the installation against the specific wind speed.

The mounting structure steel shall be as per latest IS 2062: 1992 and galvanization of the mounting structure shall be in compliance of latest IS 4759.

Structural material shall be corrosion resistant and electrolytically compatible with the materials used in the module frame, its fasteners, nuts and bolts.

Aluminium structures also can be used, particularly in rooftop installations which can withstand the wind speed of respective wind zone. 

Apart from design and selection of suitable steel grade, it is also necessary to protect the structure parts from rusting either by coating or anodization. 

Suppliers, having robust manufacturing and Coating facilities should be selected for supply of structures. 

Do We Need Stricter Product Certification Guidelines And Quality Standards For The Solar Sector?

Yes, off course. As I said earlier, there is tremendous pressure on the cost of the projects. So, wherever possible, component manufacturers would try to optimize the cost. 

Therefore, in order to ensure the desired Quality of the components, stricter Product Certifications and Quality Standards must be implemented on all critical equipment, like PV Modules, Transformer, Inverters, Cable, Panels, Module Mounting Structures etc. 

Inspection and Testing must be ensured at factory before these components are shipped to sites. 

As we know that PV module being most expensive and critical items in the PV Plant, so special focus must be given on selection and qualification of module suppliers through review of IEC / BIS certificates, factory audits, close monitoring of quality parameters during production and pre-shipment inspection according to relevant standards.  

In order to ensure reliability of PV Modules, sequential testing methods need to be incorporated.

List some of the challenges you come across while developing a project?  

Despite tremendous efforts from Government to promote Clean Energy in India, Solar industry has been facing a lot of barriers, like: 

Training and development of human resources to drive industry growth and PV adoption. 

The lack of closer industry-government cooperation for the technology to achieve scale.

Land allotment & PPA signing is a long procedure under the Generation Based Incentive scheme. 

Lack of better financing infrastructure, models and arrangements. 

Lack of collaborative, focused and goals driven R&D to help India attain technology leadership. 

Domestic manufacturing failed to take advantage of Safe-Guard import duty imposed on PV Solar Modules, even after one year of imposition.  Government should consider some other way-out in order to help the domestic Solar manufacturing sector. 

There is a need for more promotional incentives by Government and better industry-government co-operation in order to give a further push the Solar Industry in India.  

“Kalpa Power Is An End To End Solution Provider Of Solar Power Plant Projects”

0
Mr. Rounak Muthiyan, Founder & Director Kalpa Power Private Limited provides his perspective on solar rooftop sector in India and more…
  • Give us a glimpse about your company presence and offering in the solar sector?
  • Kalpa Power is an end to end solution provider of solar power plant projects. Kalpa prides itself in being able to develop solutions which are highly customised, user oriented and seek to maximize benefits through cost effective technology deployment with least operational overheads. Our team of experienced professionals make sure installations across India occur seamlessly at the same high standards ascribed by us to achieve maximum benefits from any given locations. We have achieved a capacity of 16 + MW in solar generation across India and have another 15 MW in India and 3 MW in West Asia in the pipeline.  We are in the business of solar power for the last 5 years and have the necessary experience and expertise in Design, Procurement of quality products and project execution, along with an excellent Finance and Administrative teams which manages the day to day operation and fund requirement of the company. This results in making timely project execution and commissioning. Apart from EPC team, we also have strong Operation and Maintenance team which ensures proper monitoring of installed solar power plant and aims for zero break down, by having real time monitoring system as every single unit generation from solar power plant count

Where do you see your Kalpa Power 10 years from now?

 Without subsidies, in 2016, globally solar became more competitive than the coal based or thermal power plants. Since then, the solar prices have come down substantially. In 2012, less than 10% of the annual capacity added in the world came from solar. Last year, it was over 25%. Hence there are huge growth opportunities. You have got a situation where the market is projected to grow fast and by 2022 , approximately 2% to 3% of the electricity will be generated by solar globally. The opportunity over the next 10 years is immense because this number will have to go up and become a substantial number for the world energy market.  As we are expanding our operation on a global level, alongwith current projects in pipeline we are optimistic we can make a remarkable achievement in the field of Renewable energy globally in the next 10 years. We have cumulative target of 50 MW in next 2-3 years.

Taking forward our knowledge and expertise in solar, we are venturing into solar powered Electric Vehicle supply equipment (EVSE). Traditional electricity sourced from conventional sources is expensive, and losses are high to convert electricity from AC to the required standards for EVSE for charging. Hence solar and EVSE are a natural fit. We’ve already received an EoI from large corporate and government entities in this regard. We have started development in this sector by designing and manufacturing of efficient smart chargers for electric vehicles which are expected to hit the market by the end of FY 2019 or by early FY 2020.  

What are the key drivers of growth in the solar rooftop segments?

Solar power provides a decentralized option to address growing power needs of a vast-expansive country like India. Kalpa power envisions to fulfill the needs of the country by providing cheap and affordable power. Solar power can be designed to size so as to meet the needs and requirements of the urban as well as the rural people of India by providing independence from foreign sources of energy, thus enabling stable energy prices for the future. Increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce India’s total CO2 emissions.

High energy cost and tariffs usually affects the operating margins of many manufacturers, industry and commercial complexes. Green and clean energy being a prime objective and step towards sustainable development, has been a major key drivers in the solar rooftop segments. This initiative is taken by many leading industries. Another key driver for growth is net metering policy, which encourages end consumer to take benefit of excess generation from solar power plant.

How has GST impacted solar rooftop industry in India?

GST has indeed made an impact on capital cost of solar project. According to a recent study published by the Council on Energy, Environment and Water(CEEW) and the International Institute for Sustainable Development (IISD), the introduction of GST has led to an increase in cost of generation of solar power by almost 6 per cent. The current GST structure discourages a potential client to go for solar . With the government aiming for ambitious target of 100 GW  and with current market scenario GST for solar need a relook from government. If you observe last three quarters, capacity addition of solar project have been declining. Cut down of GST on Solar rooftop should be major objective of MNRE, that will boost up solar capacity addition. It is important to continuously monitor and examine if fiscal measures are being effectively wielded, to support India’s larger national objectives with implications for sustainable development. The introduction of the safeguard duty on solar panels has compounded the uncertainty, resulting in delays in deployment of solar projects. Combined with the imposition of safeguard duty (making majority of the PV panels used expensive) and the cap on solar power tariffs, the GST impact may have a bearing on the profitability of companies in this sector.

“The “Hero Approach” Of Owning A Renewable Energy Project Is Based On Business Case Certainty Of 25 Years”

0
Mr. K.V.Sajay, President – Wind, Solar and Regulatory Affair Hero Future Energies shares his valuable insights on the significance of energy storage and untapped opportunities that can be explored.

What according to you is the biggest strength of Hero Future Energies in the solar sector?

Hero Future Energies (HFE) is the renewable energy arm of the Hero Group, which is an extremely diversified industrial conglomerate. The group’s flagship company is Hero Motocorp but we also have auto component company, finance company, electronic company, university and of course renewable energy.

We are one of India’s fastest growing renewable energy developer. The “Hero approach” of owning a renewable energy project is based on business case certainty of 25 years or more, this in turn helps to bid and build robust assets with the right HSEQ standards in a time bound manner.

How significant is energy storage for the development of solar sector?

One of the distinctive characteristics of the electric power sector is that the amount of electricity that can be generated is relatively fixed over short periods of time, although demand for electricity fluctuates throughout the day. Energy storage can assume a larger role in matching the demand and supply. At the same time, technological development, better utilization of transmission assets and rapid price reduction of other technologies like thermal storage and battery energy storage along with rapid penetration of intermittent renewable energy like solar and wind, have created a renewed demand for energy storage technologies.

Energy storage will also support buyers by supplying power during peak period along the day at competitive prices against the power from conventional sources during such period which is procured by paying premium charges.

What do you think are the untapped opportunities which needs to be explored in the solar sector?

Solar sector has evolved from being focused on heat transfer-based method of power generation to solar photovoltaic based power generation during the last decade under the JNNSM and it’s still evolving as we speak.

Thus, we see very high opportunities in the fields of domestic solar PV module manufacturing with integrated supply chain of polysilicon to PV modules instead of cells to PV modules to cater the demand of both domestic and international market (100+ GW per annum).

Technological development in battery-based energy storage system clubbed with solar/ wind energy generation has huge potential in the coming years. A shift to green alternative will be attractive as compared to conventional power based on pricing.

India has ~ 36 GW of installed wind capacity. Most of these farms also happen to be in high solar insolation zones and if proper hybridization is done even to the 50% (i.e., 18 GW) of such installed capacity along with solar and energy storage solutions, it will result in better utilization of existing transmission systems along with increase in capacity utilization factor and reduction in variability of power from renewable sources. Also, it means that about 18 GW capacity can be added in a short span of 1 year to the country’s overall renewable target.

A lot has been done to improve the policy and regulatory framework for the sector. What are the problems that persist with in the sector?

In FY18 capacity addition in renewables was 2.5 times the capacity addition in conventional energy generation during the same period. This sector has seen numerous off takers in the bids conducted by SECI, NTPC, MSEDCL, GUVNL and other nodal agencies during second half of 2018 and so far in the first half of 2019, thus we expect considerable capacity addition in the years ahead.

This wave of optimism coupled with strong regulatory framework is the need of the hour. However, challenges to be dealt includes outstanding overdues with DISCOMs, slower augmentation of transmission infrastructure, threatening and challenging the sanctity of long-term power purchase agreements by state government, uncertainty of waiver of transmission charges beyond March 2022 etc.

Additionally, to spur investment in this sector few more challenges namely mismatch in timelines of solar projects, deemed non-agricultural conversion of land for use in solar projects, curtailment of power from renewable sources and non-adherence to “Must Run” status for renewable projects need to be addressed.

It is worth mentioning that union government had already taken cognisance of situation and invited RE developers in recently conducted Chintan Baithak by MNRE to address the challenges faced by the sector. Let 2019 be the time when leaders in government and business of renewables can jointly drive sectoral growth, create employment and transit towards a carbon free economy.

What more can Indian government do to propel the growth of the sector?

To improve the bankability of projects, the government should focus on the following pointers, which might seem micro in nature but is of utmost importance to gain confidence of any investor or banker.

  • Development of single window clearance for all requisite approvals
  • Flexibility in terms of size and timing of equity infusion
  • Deemed generation compensation at 100% of applicable tariff in case of grid curtailment
  • Time bound adoption of tariff discovered under tariff based competitive bidding by ERCs without any re-examination of such discovered tariff
  • Timely payment to renewable generators
  • Extension of financial closure and commissioning timelines for actual/ genuine delays in government approvals
  • Pre-defined formula for calculating impact of new duty on cell and modules
  • Increase the duration of PPAs from existing 25 years to 35 years for solar, wind and storage-based hybrid projects


Mono Vs Poly – An Introspective Simulation Study! – Part 3

0

While the previous two parts of the article “Mono vs Poly – An introspective simulation study! – Part 1 & Part 2” introduced the types of crystalline technology, the need for this study, the methodology of study and detailed technical results of all climatic zones, this part would present a financial analysis of both the plants and educate its readers on the key takeaways from the study.

Figure 1: Division of climatic zones in India (Source: IIT Bombay)

Financial analysis

With the energy sources around the world constantly increasing, it is important for a source to be commercially viable and give back good returns to ensure its widespread uptake. In such situations, only proving a source’s technical superiority may just not be enough. An in-depth financial analysis and its gains need to be identified in detail. The initial cost break up of a solar power plant is well known and is well represented by various bodies. In such break up, the solar modules constitute more than 50% of the cost, whereas the BoS accounts for around 35% of the cost. The civil works and other costs constitute merely 13% of the cost. While the number stands true, the comparison between mono and poly crystalline technology paints a different picture.

The study presented two different scenarios; the financial analysis however is calculated on per MW basis to fairly evaluate the technology. Firstly, the fact that the initial cost of mono crystalline technology is more cannot be argued upon. This leads to a sharp increase in the module’s initial price i.e. ~21% higher than poly crystalline technology. However, now with the changing dynamics in the PV market of the world and with the world demanding higher energy from the same module size, the prices of mono crystalline PV modules are deemed to fall down drastically. It is an already known fact that mono crystalline module (of similar sizes) are usually at 1~2% higher efficient than the poly crystalline modules. This efficiency advantage leads to a direct 12% reduction in number of solar modules required per MW of power plant when utilizing mono crystalline technology. Further, considering a standard double racking design in a power plant, the cost savings in module mounting structure installed in a mono crystalline modules is 0.25% (when compared to a poly crystalline module based plant). Considering the land requirement, significant savings could be clearly realized in a mono crystalline based power plant. Considering central inverter in both the cases, we find that a mono based power plant could use 31% less land (and hence 31% less cost) compared to poly crystalline module based plant.

While designing a power plant, adequate care needs to be taken to ensure that the electrical losses are minimal and/or within the tolerance limits. One of the easiest yet important parameter to optimize is the DC voltage drop in cables. The drop depends primarily on the internal resistance of the cable which is further governed by the length and the cross sectional area of the cable. With an increase in number of modules to be utilized in a poly crystalline technology based power plant, the length of the cable increases which directly increases the internal resistance of the wire. In order to mitigate such losses, the cross sectional area of the cable needs to be increases. Both increase in length and area acts as a double whammy increasing the cabling cost of module by around 10.50% when compared to mono crystalline based power plant. Operation & maintenance (O&M) plays a significant role in any power plant if it is to run smoothly and perform as expected. Considering the case of a solar power plant, as a rule of thumb O&M cost is considered only to be around 1% annually of the plant’s total cost. However with the need to clean & maintain more modules, AJB’s and other DC spares in a poly crystalline based power plant its cost raises significantly. It was found that in a mono crystalline based power plant, a savings in O&M cost to the tune of 38% could be realized (refer Figure 2).

Figure 2: Difference in investments incurred per MW during the life time of the power plant

Figure 3: Savings realized while utilizing mono crystalline technology over the plant lifetime

With both the incurred cost and energy generated in the favour of mono crystalline technology, it should be clear by now that mono crystalline technology which looks expensive, is actually profitable in the longer run. For the purpose of study, savings across each and every climatic zone was calculated. Hot & dry zone which is expected to have enhanced savings due to temperature loss is expected to realize 9.54% of savings by utilizing mono crystalline technology. Followed to this is the moderate climatic zone at 9.49% which due to lower ambient temperatures (around the year) are expected to generate adequate energy. This is followed by composite zone at 9.37% and warm & humid zone at 9.12% which due to higher ambient temperatures experience modest savings in the northern and few north eastern parts of India, the savings for both cold & sunny and cold & cloudy are around 9%, which could again be attributed to lower ambient temperatures.

Conclusion

Mono crystalline versus poly crystalline has been one of the hot topics of discussion amongst various stakeholders at different platforms. While there has been lot of information available on the matter, a complete guide seems always missing. Further with the clear trends of the PV market tilting towards mono crystalline technology, the adoptability of PV modules in the Indian market is still primarily based on cost. It was hence necessary to evaluate the technology fully till its end of life and further carry out both technical and commercial analysis for a clear understanding. The following were the results obtained from the study (refer Table 1 & Table 2 for details):

􀃂 Utilizing mono crystalline module enable efficient utilization of land by generating 41 MWh to 52 MWh more per fixed area (1000m2). This further converts to 8 MWh/MWp to 14 MWh/MWp more energy injected into the grid annually.

􀃂 A boost in performance ratio (PR) of 3.0% (average) is found when utilizing mono crystalline technology in power plant with limited area availability. Utilizing the power plant with fixed capacity, mono crystalline technology was able to deliver a PR boost from 0.40 to 0.80%

􀃂 Mono crystalline technology has a better performance at location with enhanced ambient temperatures and hence acts as a perfect match for countries like India which lie between the tropics.

􀃂 Utilizing mono crystalline modules would enable savings in total investment over the plant’s life time to the tune of 8.94% to 9.54% annually.

􀃂 Implementing mono crystalline module to have ROI reduced between 0.5~2 years considering economies of scale Let us all pledge to make solar energy the primary source of energy in the near future.

Solar Power Is India’s Green Future

In 2018, the solar power industry saw a 24% increase in its y-o-y capacity additions, while
hydropower saw 2% and wind energy saw a 10% increase). Although a majority of the
solar capacity additions were dominated by Asia, new markets like Brazil, Saudi Arabia,
Egypt, Spain and Latin America saw considerable growth.
The remarkable upsurge in private participation in the power sector in India and the
government’s thrust on renewable energy is in sync with the country’s solar overdrive
in pursuit of the 100-GW target for solar projects, there are impeding issues like tender
cancellations of mega projects. China’s policy shift, feed-in-tariff cut in Japan, and policies
levying of taxes and duties on solar energy industry in India limited solar sector growth in
2018, but the solar sector is expected to bounce back in 2019.
With the tender process picking up pace in FY 2019-20, we have a lot to look forward to
this year. Pursuing a 40-GW target, the government is also all set to give a big push to the
rooftop segment through favourable policies like net metering.
Solar Power is India’s Green Future as it presents a great opportunity to phase out fossil
fuel and its growing expenses while transforming the country with industrial, social, and
economic growth. The future of solar energy in India largely depends on achieving the
ambitious solar power generation target of 100 GW by 2022. With the cumulative solar
capacity going up to 36.36 GW, as on June 30, 2019, the market sentiment is upbeat
because of the record number of installations.
We believe that by 2030, India’s solar industry is poised to grow phenomenally. The country will need $250 bn in green energy funds from 2023 to 2030. Investment opportunity for over $30 bn per year is expected to come up in the next decade, according to the Economic Survey.
Significantly, India is running the world’s largest renewable energy programme. Solar
power generatio holds the key to the unprecedented growth India needs to register to get
to the magic figure of 100 GW. Fuelling the ever-growing needs of practically all the other
key sectors, the power sector forms the backbone of our rapidly expanding economy.
Since sustainability is at the heart of all development efforts directed towards building a
New India, the country is aiming at increasing the share of renewables in the total installed power capacity to 50% by 2030 with a major chunk coming from solar energy. This is in tune with another dimension of Vision 2030 which foresees India as a pollution-free nation with green environs and blue skies. Renewable sources in general and solar power in particular can make all the difference here as a major source of energy supply.
It is pertinent to mention here that about 40 per cent of the power capacity installed in
India this year is solar. All-out efforts at transforming the energy mix are under way. In
the Indian solar market, almost every passing tender has promised to deliver cheaper
electricity. The solar industry is entering a period of cost efficiency, thanks to advances in
technology and competitive bidding. Solar power tariffs in India have plunged to a record
low of Rs 2.44 per unit, which will push demand in a big way.
The solar industry has witnessed rapid growth in the last few years and is expected to
grow even more in coming years. To encourage the shift from environmentally detrimental
sources of energy to cleaner alternatives, the government has been playing an active role
by introducing several incentives, such as GBIs, capital and interest subsidies, which are
likely to reduce the dependency on conventional energy and increase adoption of solar
power.
These measures involve setting up several small solar projects on barren land and
introducing solar water pumps.
To further encourage the adoption of solar power, a slew of welcome initiatives have
been recently introduced by the government, which have been welcomed across the
industry. This includes the imposition of BIS standards on solar imports, besides ensuring
adherence to the quality of products instead of mere price benefits. Another welcome
step in the concept note released by the MNRE proposes the development of 10 GW of
manufacturing capacity over a period of five years, which focuses on both poly-silicon and
wafer manufacturing to create integrated silica-to-modules packages and intermediate
standalone packages or combinations.
One of the biggest advantages of solar power is the ability to avoid the politics and price
volatility that is increasingly characterizing fossil fuel markets. While the prices of fossil fuels have increased, the per watt price of solar energy production has more than halved in the past few years, and is set to become even cheaper in the near future as better technology and economies of scale come into effect. The first benefit of using solar panels to generate electricity is that they do not produce any environmentally detrimental greenhouse gases.
Renewables account for a sizeable share of the power capacity additions, highlighting
the significant investment flowing into the solar sector in particular. No wonder, India has emerged as the third largest solar market globally. But we still have a long way to go to
become a global solar superpower like China and US.

To achieve the target, India needs heavy investment in coming years. A major part of it has to be raised within the country, as the renewable sector could so far only attract a foreign direct investment (FDI) worth $7.5 billion in the last 18 years (2000-2018), according to a report by the India Brand Equity Foundation.

The solar sector can accelerate its growth by focusing on manufacturing and supporting
domestic solar panel manufacturing industry with sizeable investments. This will help India
scale greater heights like China, which penetrated foreign markets by undercutting their
market prices. By working overtime on its solar panel manufacturing capacity, China was
able to support its own solarisation, ring in revenues from exports and create jobs. India
needs to follow a similar roadmap.
We need to pick up on the domestic manufacturing front. Various efforts by the Solar
Energy Corporation of India (SECI) to attract bids for the development of the inter-state
transmission system for solar power evacuation have gone in vain. Solar power generation
has to be in sync with the growth in transmission capacities owing to evacuation challenges, otherwise we may be in for a slowdown.
Though rooftop solar is the fastest growing renewable energy segment in India, the
installation capacities must rapidly increase if the nation is to meet its ambitious renewable energy target by 2022. Conducive policies, financial support and consumer awareness should form our focus of attention.
Around 70 per cent of the market growth in rooftop solar is driven by commercial and
industrial consumers. The residential segment is lagging owing to lack of policy initiatives.
The 20-40 per cent financial subsidy for new residential rooftop solar installations should
accelerate the pace of growth. But India needs a more comprehensive approach in order
to achieve the 2022 target.
The industry needs to be steered in the right direction to take us closer to the 100-GW
goal. We need integrated energy planning, favourable policies and investments across the
value chain. Release of RTC tenders and incentives for OA charges are critical. RTC supply
is one alternative to ensure predictability in supply, thereby ensuring grid stability and
off take guarantee by discoms under all circumstances.
While on one hand we need to promote solar projects based on domestic manufacturing
capacities to make ourselves self-sufficient, the Central and state governments should take care not to put the auction process on hold in the expectation of a further drop in prices.
We also direly need a universal anti-dumping policy and incentives to instill confidence in
Indian companies. Investing in domestic manufacturing can help build the supply chain,
control prices and earn foreign exchange through exports. It will also create jobs, enhance
the country’s GDP and correct the adverse balance of payments.
India should leverage its position in the 121-nation International Solar Alliance by
assuming a leadership role to make way for greater growth through favourable policies
and coordinated efforts. As a global solar superpower in the making, we ought tp wrest
this initiative. With a proactive approach driven by all these factors, India’s solar Power will usher a green and sustainable future.

LeTID Testing To Mitigate Investment Risk

0

The PERC technology (Passivated Emitter and Rear Cell) typically boosts the module power by about 10%. This boost however is threatened by a PERC-related degradation mechanisms, which might eat up this gain in the field completely:

In addition to the known Light Induced Degradation (LID) effect, the Light and Elevated Temperature Induced Degradation (LeTID) was reported for modules based on p-type crystalline silicon PERC cells, independent of its Boron-Oxygen content, in 2012 by Ramspeck [1].

Difference between LID and LeTID on mono and multi silicon

Unlike LID, LeTID shows:

1. A longer degradation interval in the field, i.e. years instead of days

2. A larger degradation depth, i.e. up to -10% instead of -1% (multi) and -3% (mono)

3. A recovery to the initial power in the field, but unfortunately again over an interval of several years depending on the local temperatures and irradiations. Figure 1 shows results from field testing by Kersten in 2015 and further results on degradation and recovery intervals in the field by Kersten in 2017 [2].

The mechanism behind LeTID is still not fully understood. The existing theoretical models predict higher degradation depths for multicrystalline than for monocrystalline PERC modules. Despite this, PI Berlin has found similar high degradation depth and durations on monocrystalline PERC modules in laboratory tests as well, as shown in Figure 2.

Further, comparison of LeTID Test results on two multicrystalline modules and 8 monocrystalline modules are shown in Figure 3.

LeTID test results on ten different modules, two multicrystalline modules and 8 monocrystalline modules. The degrees of degradation range from zero to minus four percent. Source: PI Berlin

How to supress LeTID

Some manufacturers have enforced counter-measures to suppress LeTID by either changing their cell process or applying a super-fast degradation and recovery procedure at the end of their cell line using high irradiance and temperatures or even both, e.g. Jinko’s Andrea Viaro presentation under https://www.pv-magazine.com/webinars/secure-your-investment-discover-urgently-required-game-changing-solutions-in-managing-letid/

field with cumulated irradiation data in kWh and power loss in % under accelerating
conditions, i.e. open circuit and thermal insulation of the module backside.
Initial 48h 96h 168h 336h 936h

How to protect your project against LeTID

The current certification procedures does not cover LeTID checks for the module qualification after IEC 61215:2016. The new draft version or this standard intends to include LeTID tests but the procedure is still under discussion. Mitsui Chemicals is involved in this process with an expert from Japan’s National Committee of IEC TC82/WG2.

To prevent commercial damage for the investor’s side, it is recommended to test LeTID sensitivity on samples from the actual shipment lots, see also [3]. PI Berlin and Mitsui recommend and offer laboratory tests to check the LeTID sensitivity on a project by project basis to protect investor risk. At this point in time, LeTID is still not yet fully understood nor is it sufficiently controlled by the photovoltaic community.

“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.
