Why solar/PV is good for India? An ISA perspective!

Recently, the India Semiconductor Association (ISA) held an educative briefing session on the potential of the solar PV market in India, which was conducted by Rajiv Jain, Director, Government Relations, ISA.

This meeting was held well before iSuppli issued a warning that there could be global solar sunburn in 2009! I am sincerely hoping that most of the points mentioned by ISA's Jain still hold good in the coming year, and that India really does well and takes off in solar photovoltaics.

The ISA's vision: To help make India an attractive global destination for PV manufacturing and a world leader in solar energy.

Starting with the basics of photovoltaics, he said that it is a package of solar cells used to convert energy from sun to electricity. In simpler words, photons from sunlight knock electrons into higher state of energy, thus creating electricity. The electricity can be used to power equipment or recharge a battery. A typical PV system mainly consists of a PV module, battery, inverter, controller and junction box.

Focusing on the technological landscape, he touched upon the two key technologies for solar: crystalline and thin film.

Crystalline silicon is said to be the most mature Si wafer technology, with the largest market share. Though, high on cost, it has a typical efficieny of 14-18 percent. Crystalline silicon is said to suitable for rooftop applications.

Thin film is nothing but thin layers of photosensitive materials on glass. It is currently on high growth due to silicon shortage, and very low on cost due to low material consumption. The efficiency is about 6.5-8 percent.

A third technology, nanotechnology, is the future technology for cost reduction. It is more in the R&D space as of now.

Present scenario for solar
So what's the present scenario? In 2007, of $71 billion invested in new renewable energy (RE) capacity globally, 30 percent was in solar PV. It is the fastest growing area in the energy sector, with a CAGR of 47 percent over the last five years.

Grid-connected solar PV has been high growth market segment in 2007 (50 percent increase). Also, 86 percent of the PV installations are largely in four countries, with Germany at 47 percent being the outright leader.

Market drivers are said to be attractive feed-in tariffs, national PV market development and acceptance, RE obligations through solar PV, access to cheaper mode of finance, manufacturing incentives as well as strong R&D.

Why solar for India
I have addressed this in an earlier blog post. Here's what Jain had to say, and it is mostly in line with the earlier discussions.

First, India has among the highest solar irradiance globally. It also has the best quality reserves of silica in Orissa and Andhra Pradesh. India has also established itself low cost producer and assembler of solar PV cells and modules.

The major challenges include attaining scale and integration for cost reduction, and, R&D for development of the industry.

Solar insolation in India
To start with, the daily average solar energy incident varies from 4-7kWh per m2. Next, we have multiple sites with solar irradiation >2000 hours per year. In contrast, Germany has 900-1,200 hours per year. Further, most parts of India have 300-300 sunny days in a year translating into a potential of 600GW. Also, potential in some states like Rajasthan is 35-40 MW per m2.

It is well known that the Indian semiconductor policy of 2007 has triggered off the now well publicized efforts in solar initiatives. The government of India has received 16 applications with investments envisaged at app Rs. 1,55,000 crores.

The investments in solar PV manufacturing exceed Rs 1,25,000 crores. Generation based incentives (GBI) are going to be key.

Potential market segments in India
There are quite a few, actually. In rural electrification, the government of India's target is to achieve 'Electricity for all by 2012'. About 18,000 remote villages will likely be electrified through RE. About ~25 percent of the remote villages, i.e., 4,500 villages, form a very viable market.

Next comes telecom back-up power! PV is a cost effective alternative to diesel generators (DG) for back up power for shorter duration, as DG based systems suffer from several disadvantages.

Another key market could be grid connected solar PV based generation. Current tariffs do not provide attractive IRR to developers. Decreasing system prices are however, likely to improve the economics.

Finally, roof based BIPV is said to be an alternative to reduce the cost of power procured by commercial buildings.

ISA's recommendations
The ISA has also made salient recommendations via its report on the industry. These include areas such as manufacturing: with an aim to encourage companies investing in 'Scale and integration', provision of capital subsidy to larger number of units, availability of funds at a cheaper rate, and an emphasis on R&D.

Also, the ISA has recommended that GBI be given for a tenure of 20 years, with the present period being 10 years. Further, it has suggested an accelerated depreciation along with the GBI scheme, and the availability of GBI for an unlimited capacity for a period of five years. The ISA has recommended an enactment of the RE Law requiring utilities to progressively increase power purchase from RE.

On its part, the ISA has been working with the government of India and various state governments as well. It has a sound rapport with concerned ministries - MNRE, DIT and NMCC.

The ISA has also assisted in the technical evaluation of solar PV proposals received in Fab City, Hyderabad. It has also drafted a semiconductor policy for the government of Karnataka, which should be out early next year, hopefully. The ISA is also working with several other state governments to promote the industry in their states.

The second ISA Solar PV Conclave is scheduled for November 2009 at Hyderabad.

Very good intentions, all of these! Now, for the Indian industry and the government to deliver, and walk hand in hand!!

Solar/PV is just right for India

There have been significant investments in the solar/photovoltaic space in India in the recent past, and that does not look like ending any time soon.

Given the ongoing global financial crisis, and the state of the global semiconductor industry, it appears that India has bet quite successfully on the solar/PV segment. In fact, it seems that solar/PV is just right for India! In fact, it may just kick off the kind manufacturing activity India really needs.

Poornima Shenoy, president, India Semiconductor Association (ISA), says that solar/PV is right for India for a variety of reasons.

Firstly, India has among the highest solar irradiance, globally. Secondly, it is established as a low-cost producer and assembler of solar PV cells and modules. And thirdly, India has among the best quality reserves of silica in the states of Orissa and Andhra Pradesh.

She adds: "At present, solar PV may not seem to be an attractive option, primarily due to high generation costs. However, in the coming years, with increases in fossil fuel prices, rising environmental concerns, and a reduction in the cost of solar PV technology, it is likely to become a major source of energy."

The ISA expects 2015 to be an important year for the solar/PV industry. Around this time, the product cost of the Indian solar PV industry is likely to match the semi grid parity (peak power) globally, and also to match the grid parity within India.

The four major segments offering maximum potential in the coming years for solar PV in India are: rural electrification -- decentralized distributed generation (DDG); grid interactive solar PV power plants; backup power for telecom (base transceiver stations); and roof-based solar PV systems.

ISA-NMCC report on solar/PV
The ISA recently released a report on the solar PV market in New Delhi with NMCC (National Manufacturing Competitiveness Council).

According to the ISA-NMCC study, of the US$71 billion invested in new, renewable energy capacity globally in 2007, 30 percent of was in solar PV. Solar PV is the fastest growing area in the energy sector, with a CAGR of 47 percent over the last five years. The grid-connected solar PV segment saw 50 percent growth in 2007.

As per the report, the solar PV industry is likely to grow four-fold by 2011. However, there are various uncertainties in the short- to medium-term on both the supply and the demand side.

On the supply side, the main constraint is the lack of available polysilicon. The demand side is limited by the quantum of incentives for solar PV.

Gradually, there will likely be improvements in technology. The decreasing cost of manufacturing could drive the preferential tariffs lower, and ongoing demand for PV products could also attract significant investment.

As for the global solar PV supply chain. Thin-film production is one of the fastest growing segments in solar. The lack of available polysilicon is limiting growth, and this has led to the emergence of thin-film technology. This technology has enjoyed substantial growth since 2005: 80 percent in 2006 and over 100 percent in 2007.

Building a good solar ecosystem in India

Solar/PV has been doing the rounds consistently, and has probably now become one of the most hyped sectors.

In fact, renewable energy has never ever had such a good time! As mentioned, a tremendous hype has already been built around solar photovoltaics. Several companies, in India, and elsewhere, have also jumped into the solar bandwagon.

So what are the reasons behind this 'sudden' interest in solar? According to Dr. Ashok Das, managing director, Solar Solutions, and a well know expert in this area, consumers do not yet drive the solar energy sector. Being energy, it is mostly driven by the government and its subsidies.

So, why has there been this 'sudden interest' in solar? There are two reasons.

First, the climate change issue started getting center stage at world forums, leading to policies and targets to cut global warming, and hence boosting renewable energy. Second, the soaring oil prices and continued dependence on a few countries for oil has led to the realization of the energy security.

There are several takeaways from the European experience with solar. Dr. Das says that Europe, particularly, has taken solar very seriously. They have been a leader in solar. "Germany, for instance, gave away all of the necessary subsidies to attain energy security. These subsidies have led to the solar boom. It has also led to an increased R&D to bring down the cost of solar energy."

Nevertheless, he adds there seems to be a bubble forming in this sector, like all other booms in the past. The industry will go through consolidation as the market matures.

And where does India stand in comparison? According to Dr. Das, steps are being taken to promote solar energy in India. "As of now, the feed-in tariff is Rs. 15 for photovoltaics and Rs. 12 for thermal solar. The government also announced a mandatory 5 percent renewable energy mix in the electricity production.

"The PMO (Prime Minister's Office) has also issued a National Action Plan that has plans for boosting solar. These subsidies are driving some of the increased activities in India."

He contends: "We need stronger lobbying so that better subsidies can come through. Therefore, most of the manufacturing activities in India are still driven by the export markets."

Surely, given the surge of investments in solar within India, there is every room for developing a very good ecosystem.

Dr. Das says: "Coming to the solar ecosystem, we already make solar products, as well as the modules. We also have the capability to make cells. The only part missing has been wafer, the silicon for solar.

"A few silicon factories should be coming up in India soon. So, India can easily establish the entire ecosystem for solar photovoltaics."

Postscript: More investments in solar today, in India. According to Hindu Business Line, there have been three additional investments worth Rs. 55,000 crores.

Vavasi Telegence to invest Rs 39,000 crore for solar PV and polysilicon unit; EPV Solar to invest Rs 4,000 crore for solar PV unit; and Lanco Solar to invest Rs 12,938-crore for solar PV and polysilicon unit.

A word of caution: It's advisable not to get carried away by all the success in solar. Solar is/was only part of the ecosystem units in the Indian semicon policy.

Don't forget semiconductors!

While this success in solar does augur well for the solar industry in India, don't think this is even close to what the Indian semicon policy, launched with fanfare last September, originally set out to achieve!
