    Many reasons make India a great investment destination for new and renewable energy firms from all over the world, especially the size of its market, its speeding growth, its future potential and its political and economic stability.

    India will be the second world economy, after China, to receive more Foreign Direct Investment (FDI) in the coming years, according to the World Investment Prospects Survey for 2007-2009, released by the United Nations Conference on Trade and Development (UNCTAD) on Nov. 1, 2007.

    According to Development Counsellors International (DCI), a U.S. marketing company, India is the second-best country after China for business investment. DCI cites India's labor, including its supply, skills level and cost, as the main reason for this positive perception.

    India's National Solar Mission

    The Government of India has come out with a "National Solar Mission" along the lines of its Atomic Commission as part of the National Action Plan on Climate Change, to significantly increase the share of solar energy in the total energy mix. It also recognizes the need to expand the scope of other renewable and non-fossil options such as nuclear energy, wind energy and biomass.

    The solar mission has a limited target of adding 1,000 MW of concentrated solar power (CSP) in the next 10 years. Yet many consider even the 1,000 MW target to be too ambitious. That's simply because in the past 60 years practically nothing has been done to build capacity -- either in collaborative research or in creating the manpower.

    Another aspect of the solar mission would be to launch a major R&D program, which could also draw upon international cooperation, to enable the creation of more affordable and convenient solar power systems and to promote innovations that enable the storage of solar power for sustained, long-term use.

    The mission is expected to come up with suggestions to ensure optimum utilization of solar energy, which has vast potential in the country, to bridge the energy shortage through proper applications.

    India's Prime Minister, Dr. Manmohan Singh, has also shown keen interest in developing India's capacity to tap the power of the sun in order to increase sustainable sources of energy.

    "The sun occupies center stage, as it should, being literally the original source of all energy. We will pool all our scientific, technical and managerial talents with financial sources to develop solar energy as a source of abundant energy to power our economy and to transform the lives of our people," he said.

    Solar energy is gaining importance from every corner and scientists across the country foresee in it a solution to the energy crisis. Many of them have recommended that the immediate solution to India's energy problem lies in tapping of solar energy. Scientists believe that the government should concentrate on tapping the conventional sources of energy like wind and solar to meet the country's immediate energy requirements.

    India receives clear sunshine for a major part of the year in most areas. However, only about 1, 748 MW of its power is produced from solar energy. This could be enhanced substantially. Solar energy, with an appropriate technology, would be one of the most replenishing, pollution-free and inexhaustible sources of energy.

    Apart from the fact that India has the highest potential in the world to harness sun power, the country also has the potential to be the least-cost producer and assembler of solar cells. The Indian industry is now focusing more on R&D in areas such as raising the percentage of solar energy falling on the panels that is turned into electricity and bringing down the cost of production of its raw materials to make it affordable.

    Most urban and industrial centers in India are facing electricity shortages of over 15 percent. Taking a cue from London, Tokyo, New York and Adelaide, the government of India has taken the initiative to develop 60 cities as "solar cities".

    Through the use of solar energy, a minimum 10-percent reduction in total demand of conventional energy could be achieved after five years in each of these cities by efficiency and renewable energy measures. If these plans materialize, India will become a role model for solar cities worldwide.

    It is believed that the proposed national solar mission would play a significant role to meet the energy needs in India in the years to come. Some progress has already been made in this area, and the new initiative would strengthen it further.

    India, a manufacturers' hub

    In March 2007 the Indian government announced a semiconductor policy under its Special Incentive Package Scheme (SIPS). According to this policy, the government or its agencies will provide 20 percent of the capital expenditure during the first 10 years for semiconductor industries, including manufacturing activities related to solar PV technology located in Special Economic Zones (SEZ), and 25 percent for industries not located in an SEZ. However, non-SEZ units would be exempt from countervailing duty (CVD) -- an additional customs duty equal to the excise duty charged on similar domestic products.

    The policy has attracted a tremendous response, so far receiving nine proposals pertaining to solar PV-related manufacturing worth US$18 billion.

    Inspired by the semiconductor policy, the Andhra Pradesh state government has set up FabCity in the capital, Hyderabad, at an estimated cost of US$3.18 billion. Spread over 1,200 acres (486 hectares), FabCity will house semiconductor manufacturing companies working to meet the needs of the electronic hardware sector and fabrication units for solar PV.

    A company called FabCity SPV (India) Private Limited has been set up to implement the project. The Andhra Pradesh Industrial Infrastructure Corporation (APIIC), the government's industrial development agency, will have an 89-percent stake in this company. SemIndia Inc. will participate in the development of FabCity as an anchor industry with an 11-percent stake. To date, FabCity has seen nearly a dozen investments from the solar PV industry worth more than $7 billion and, according to APIIC, another 40 applicants have submitted proposals.

    FabCity is the largest investment ever made in India in the technology sector. It marks the first step towards India becoming a $33.6-billion semiconductor market employing some 3.6 million people by the year 2015, as projected by consultants Frost & Sullivan.

    Another southern Indian city, Bangalore -- the "Silicon Valley of India" -- will also witness intense activity in solar PV manufacturing, following a recent announcement on semiconductor policy by the government of the state, Karnataka. The state is examining the various semiconductor policies announced so far and wants to draft a policy which overcomes the ambiguities in some other state policies.

    Along with government-backed developments, a number of individual companies are also making efforts to develop PV capacities in India. Reliance Industries leads the field with the highest volume of investment, although a company spokesman explained its plans are still being finalized. Reliance has, however, submitted an application for a 5 MW grid-connected solar PV project in West Bengal.

    India's Moser Baer Photovoltaic Ltd (MBPVL), which manufactures 80 MW of crystalline cells, 50 MW of thin-film modules and 10 MW of concentrator modules, hopes to produce more than 600 MW of thin-film single modules and 500 MW of crystalline and concentrator modules by 2010. MBPVL plans to invest US$4 million in a PV and nanotechnology factory in Tamil Nadu.

    The US-based Signet Solar has signed a memorandum of understanding with the government of Tamil Nadu to manufacture 300 MW of thin-film PV modules in a project worth an estimated $500 million. The plant will be located in the Sriperumbudur SEZ. It will initially export most of its production, but will serve the Indian market as domestic demand picks up. The first shipments from the plant are expected in 2010. Signet Solar plans to build three plants (1 GW) in India over the next 10 years at multiple locations.

    Solar Semiconductor has an order book of $1.5 billion to $2 billion to be delivered in the next two to three years. It has orders to supply PV modules to leading players in the global solar market including Q-Cells AG, IBC Solar and ersol Solar Energy of Germany and Motech Industries of Taiwan. Solar Semiconductor's supply contract with Q-Cells is worth $170 million, for example. The company already has two operating facilities with an installed capacity of 60-70 MW on the outskirts of Hyderabad.

    Mola Solaire Produktions GmbH, a manufacturer of multi-crystalline and mono-crystalline solar wafers, has signed a five-year contract to supply 125 MW of multi-crystalline solar wafers to XL Telecom & Energy Ltd between 2008 and 2013.

    Sharp, the global leader in solar PV technology, recently made a foray into solar energy in India with its Sharp Business Systems India Ltd. subsidiary. According to a company spokesman, it will focus its activities on supplying large-scale grid-connected systems and targets 8 MW installed by 2010.

    Centrotherm Photovoltaics AG of Germany plans to set up a 5,000-ton capacity (expandable to 10,000 tons) polysilicon processing factory at Haldia in the state of West Bengal in eastern India at an investment of US$8 billion. This is a joint venture with SREI Infrastructure Finance Ltd, Environ Energy Deck Services and US-based Perseus. The factory is likely to be the first such plant in India and the state government has already allotted a quarter of the land needed for the 790-acre (320 hectare) project. The factory will produce both electronic and solar grade silicon and will be equipped with a 100 MW captive power plant. SREI and Environ Energy together will have a 50-percent stake in the project, while Centrotherm is likely to pick up a 15-percent stake in the venture. In addition, the IBM Thomas J Watson Research Centre (the headquarters for IBM Research in the country) has also expressed a desire to participate in solar energy and silicon research in West Bengal.

    It is not just foreign interests that are exploring the possibility of expanding solar PV capacities in India. Tata BP Solar, a joint venture between the giant Tata Group of India and BP Solar of the UK (and one of the oldest semiconductor manufacturers in India) is in the advanced stages of a $100-million investment in a 128 MW solar cell manufacturing plant close to its existing facility near Bangalore, which will eventually be scaled up to 180 MW. Tata BP Solar recently announced that it has signed an agreement with Calyon Bank (Credit Agricole CIB) and BNP Paribas to raise $78 million to fund further development. Tata BP Solar currently has a module manufacturing capacity of 85 MW.

    Other national initiatives

    To keep pace with the global trend of exercising feed-in-tariff solar power, the Ministry of New and Renewable Energy has produced a set of initiatives aimed at bolstering solar generation. Solar PV projects up to a maximum capacity of 50 MW are to be supported by financial incentives of a maximum of US$0.24/kWh for PV projects and US$0.20/kWh for solar thermal power projects for a period of 10 years. With investors rushing to set up solar power projects and adding up to 2,500 MW of capacity, the Ministry has asked the Planning Commission and the Indian Cabinet to expand the 11th Plan solar power program beyond 50 MW.

    The solar energy industry in India has undoubtedly gained momentum and should be able to keep pace with the government's aim of achieving 10 percent of the country's total electricity requirements by 2012. India already possesses a balanced eco-system for the PV industry, a high-tech manufacturing base and skilled labor sufficient to make it a booming industry. Annual PV production has already reached over 300 MW, with about 85 percent being exported.

    India receives solar energy equivalent to over five trillion MWh a year, far more than its total energy consumption, and should therefore benefit from economies of scale that are unavailable to smaller countries. However, it is necessary to address the availability and management of a strong infrastructure and the need to consider a long-term solar energy policy (20 to 25 years).

    Rajesh Bhat, director and country manager for Sun Technics, says: "The government of India should consider feed-in-tariff schemes in excess of 1,000 MW per year against the present 50 MW, since the need of the hour is to support PV programs which are cost-prohibitive in comparison to other renewable technologies. This would further encourage local companies to consider investing in solar PV projects and can help in their economics. India currently has to depend largely on imports of raw materials and the rising currency rates make manufacturing a burden." With government support for PV growing, ample solar resources and both the labor and the market potential to exploit these resources, India is set to become a major force in the future PV world.

    India's estimated energy requirement is about 130,000 MW of electricity per annum. Its current peak demand exceeds the available supply by a shocking 14 percent. In addition, at least 40 percent of the country's electricity supply is lost in transmission due to theft. Use of solar energy could help to check this loss and indirectly also contribute to the energy basket in a significant way.

    The prospects of 100,000 jobs

    The budding solar industry in India, somewhat pegged back by the poor economic climate, wants the National Solar Mission to be operative. The National Action Plan for Climate Change, experts say, is excellent as a program but the government needs to fix "quantitative goals". That would help de-carbonize the power sector to an extent, generate domestic demand, and propel the industry, while creating jobs.

    The Ministry of New and Renewable Energy (MNRE) says that about 100,000 jobs can be created by the solar PV industry in India by 2020 -- the industry says the number could be even higher. However, that can only happen when India's installed power generation capacity for PV grows beyond the current 100 megawatt peak (MWp); grid-connected solar PV generation is now at 2.12 MWp.

    The social benefit aside, there is a strong case for promoting the solar industry. Coal reserves may not last beyond 40 years and India's energy deficit situation implies the country may not sustain its current pace of growth, growing forward.

    India's grid-connected power generation capacity will need to scale from 147GW currently to 460GW by 2030 while the country's primary energy demand is expected to grow from 400 million tons of oil equivalent to well over 1,200 million by 2030. India's power supply-demand gap has averaged between 8 and 10 per cent over the last decade where electricity access exists.

    "About 51 percent of our households don't have electricity. They are not asking for grid electricity. They are simply asking for light; may be for watching television. Solar is the best way to do that," CEO of Tata BP Solar K. Subramanya says. His firm has electrified more than 30,000 homes.

    "The major issue is cost per watt. You can bring that down through scale. The other imperative is the process technology manufacturers' use. The third is materials and panel sizes. You may bring the cost down by doing some clever things on the systems side," says Dr. Madhusudan Atre, president of chip and solar equipment maker Applied Materials India.

    Indian technology breakthrough

    While solar energy is renewable and eco-friendly, it is also an expensive affair. Now, that's all going to change. In a first-of-its-kind technology in the solar energy industry in India, the University of Pune's department of physics has developed a nano-crystalline silicon solar cell which promises to be at least five times less expensive than the current cost. The department is carrying out the project in collaboration with an Italian university and is funded by the Department of Science and Technology (DST).

    Currently, a thin film is used in the solar silicon cell, and the project aims at replacing the film with nano-crystalline material which will reduce the cost to less than $1 from the present $5 to $6. As part of the joint collaboration, the fabrication work will be done in the department's laboratory while the testing will be carried out at the University of Camerino (UoC), Italy.

    Titled "Synthesis and characterization of hydrogenated nano-crystalline silicon for solar cell fabrication", the project has been selected in the framework of the Indo-Italian program of scientific and technological cooperation for 2008-2010 by the DST. This is also a first-of-its-kind effort in India, while the U.S. is in the process of developing similar system for generation of solar energy.

    We question whether altenergy has the BTUs IN for advertized BTUs OUT.

    1 kWh = 3412.14163 BTU.

    fast neutron Santa Fe, NM January 12, 2009

    From actual experience, wind farms produce 1.2 watts per square meter. Solar Thermal and Photovoltaic methods capture 5 to 6 watts per square meter. There is no economy of size in either technology. Dividing the watts you need by those values gives the land area in square meters needed to produce the juice. The numbers are astronomical

    Chairman, President and CEO Questar Corporation Keith O. Rattie said on April 2, 2009

    Why did my generation fail to develop wind and solar? Because our energy choices are ruthlessly ruled, not by political judgments, but by the immutable laws of thermodynamics. In engineer-speak, turning diffused sources of energy such as photons in sunlight or the kinetic energy in wind requires massive investment to concentrate that energy into a form that's usable on any meaningful scale.

    Dear Mr. Payne,

    I think your figures are off somewhat. You say that PV captures 5 to 6 watts per square meter. Generally, at noon, the sun radiates approx 1,000 watts/m2 onto the Earth's surface. Even very 'bad' PV cells are about 6% efficient. .06 x 1,000 = 60

    I think your figures for wind energy are off as well.

    Sincerely, LKelley@goruby.com

    Don Hirschberg
    6.9.09
    Bill and Larry. Perhaps 60 watts/m^2 at noon on a clear day isn't as different from 5 or 6 watts average as it appears at first blush. Just to get a ball park figure: acceppting the 60 watt figure, on an annual basis, let's say we get sun energy at half the ideal noon value for ten hours per day, and perfect sky for 80% of the time. Then 60 x .5 x10/24 x.80 = 10 watts/m^2. The kwh's we get, and when we get them is of the essence.

    Sasi Kottayil
    6.11.09
    Shall I make small modifications in your estimates? A peak insolation of 1000 W gives an average of about 60% of it (treating the sun path sinusoidal). Then the solar power density for the conditions mentioned will be 60 x .6 x10/24 x.80 = 12 watts/m^2. When it comes to a windfarm, taking the land requirement as 2Dx3D, the power output density will be around 50 watts/m^2. That is 250,000/(60x90). Considering a capacity factor of 30%, it yields a figure of 15 watts/m^2.

    Article by Mr.Ramanathan Menon is timely and interesting. "No power is costlier than No Power" so spoke Dr.Homi Jehangir Bhabha. Renewable Energy like Solar, Wind, Biomass, Microhydel etc., can play a significant role to supplement Conventional Energy like Coal, Gas, Petroleum etc., in the country. The country has installed capacity of about 1,42,000 MW and it is estimated that Renewable Energy potential in India is about 1,83,000 MW while the installed Renewable Energy is only 13,741 MW. Recently US President Mr. Barack Obama suggested India and United States can build a renewable energy partnership to find solutions to climate change issues. In Europe a lot of interest is there in Off-shore wind farms. In our country also we can have a thorough Wind survey on the coast and can harness energy through Off-Shore. Yet another area where immediate results can be seen is Energy Conservation. It is estimated through advanced lighting like Digital (White Light Emitting Diodes), energy saving in Irrigation pump sets, in Industries about 25,000 MW power can be saved. Our motto should be,” Put the RENEWABLES to Work” : To get inexhaustible, pollution - free energy which cannot be misused”.

    The above comments suggest a need to make a distinction between two types of solar energy. The first is what I will call "Instantaneous" solar energy, which produces power which is proportional to the actual photon flux at a particular time of day or year. This is what Photovoltaic Energy (PV) does, as does Concentrating Solar Power (CSP), although the latter, with additional expense, can cause some production to be "offset" for a few hours into the evening.

    The second type is "residual solar", which has accumulated in the atmosphere as a result of past insolation. What we call "wind" energy is actually "residual solar" stored in the form of pressure differences (highs and lows) that have been created in the atmosphere.

    Residual solar energy can be stored as "temperature differences" either in the atmosphere or in surface waters, such as seawater or seasonably warm lake water.

    The type stored in the atmosphere is denominated Convective Available Potential Energy (CAPE), which is an instability created by the fact that the troposphere is heated from below and cooled from above. Eric Michaud, of AVEtec, has estimated that the amount of CAPE in the lowest kilometer of the atmosphere to be roughly equivalent to twice the amount of energy in all the remaining petroleum reserves.

    Similarly, he estimates the thermal reserves stored in the top 100 meters of seawater, often called Ocean Thermal, based on only a 3 degree C rise, to be ten times this amount.

    No fraction of these energy sources would be recoverable, however, if there did not exist a vast reservoir which could serve as a "cold temperature sink" combined with a technology (device) to enable access to it.

    Fortunately, such a sink exists in the upper troposphere at temperatures around -50 C. That is what the Atmospheric Vortex Engine technology is designed to exploit in order to produce electric power far more economically that any other renewable technology is capable of doing unless it also includes an AVE in the loop.

    India moving with the SUN

    An abandoned thermal power plant in Asansol, India, has been converted into a mega solar power generating station - perhaps the only instance in the world where a high-carbon power unit has been replaced by a zero-carbon one. What’s more, the 2-MW project marks the first time in India that a solar project has crossed the megawatt threshold and is poised to give a huge fillip to India’s renewable energy ambitions.

    It’s being considered the first significant climate-responsive project in South Asia and marks the culmination of solar man S P Gon Chaudhuri’s lifetime dream. Six years ago, the diminutive man who is a giant figure in the Indian solar space, won the Ashden award, better known as the Green Oscar.

    “This is empowerment of India in green energy and demonstrates the country’s intent and ability to be climate responsive in the energy sector. It has already catalyzed commercial interest in solar power that has been shunned by private companies till now due to high capital investment and a longer break-even period,” says Gon Chaudhuri, managing director of the West Bengal Green Energy Development Corporation in Kolkata.

    In a few years, with the use of nanotechnology, the cost of setting up a solar power plant will be reduced by half, thereby negating the argument that mass producing solar power is cost prohibitive.

    A 6-MW coal-based thermal power plant of Dishergarh Power Supply Co (DPSC) once stood on the 8-acre plot that is now the site of the solar project, comprising 9,000 crystalline type solar modules of 230 watt each. The plant will generate 3 million units of electricity a year, enough to light up 2,000 rural or 500 urban households.

    The facility will save a whopping 700,000 tons of carbon dioxide emission a day - the CO2 that a 2-MW thermal project emits daily. The power the solar plant will generate will be fed into DPSC’s grid for distribution to customers in the Asansol-Raniganj belt.

    Wind does not produce any watts/sq.m when the wind is not blowing. Data from Ontario from the IESO as we speak is that for an installed capacity of 887MW actual wind energy production is 27MW and these are the windiest sites in Ontario Canada. Total contribution to current demand is 27MW in 24000 MW or just over 0.1%. If India intends to run much of anything I suggest nuclear power plants will be your best option. Current wind capacity factor is 24/887 = 2.71%. That is not very good. Overall nuclear capacity factor right now is 10075/10347 = 97.4%. This is actual data. Look it up for yourself and tell me that wind is an option for running an industrial economy. It isn't.

    Strongly advise India not to rely too heavily on such a power source. Nameplate numbers do not tell the true story. It is a number that looks good on paper but you cannot run factories to make things based on poor capacity factors and unreliable production. India will not make progress this way.

    I wish it were otherwise but it just is not. I do not have numbers for solar power plants as there are none of any size in this Province but I do foresee that at night the CF will be zero however many MW are installed.

    Ramanathan,

    I am presuming from your post that in India the Sun shines at night. If that is NOT the case please tell me what is supplying all these households when the solar plant is producing nothing. I suggest that coal is filling the gap.

    Malcolm, there is nothing to be sarcastic about and if you are not sarcastic, then you are ignorant of the fact that the sun never shines at night in any part of the world ( at least that I am sure of ). Further in the first mail itself, Ramanathan had mentioned that the coal plant is ABANDONED. I cannot say whether you read that or not and if read whether you have understood it or not.

    My views on conversion would be as follows. At 1000 W/m2 incident solar energy & 15% PV conversion efficiency, 150 W/m2 of DC power is available out of PV module. At 65% conversion efficiency from DC to AC power ( considering battery chg/dischg efficiency, cable losses, inverter & charge controller efficiency etc. ), we get 97.5 W/m2 of AC power. At an average generation of 5 hours per day, usable AC energy generated is 487.5 Whr per day. Efficiency figures considered are typical and there would certainly be variations depending on the type & rating of PV module, battery, inverter etc. etc. Daily generation will also vary with insolation, duration of available sun light, temp. etc.

    The article is very informative but its like venturing into a parallel universe. The picture drawn here and what one sees on the ground in India need to be reconciled. Maybe someone can help sort out the facts for me.

    1) On the matter of feed-in tarriffs: The Minister of New & Renewable Energy did indeed announce in January 2008 that there would be feed-in tariffs for solar PV projects up to a maximum capacity of 50MW. There was a flurry of applications filed. How many of these projects are actually deployed on in actual process of being deployed?

    2) The Solar Mission announcement this year says going forward, feed-in tariffs would be set up variosu state regulators. What then happens to the feed-in tariffs announced by the Union Government as above?

    3) The article says 1,748MW of power in India is produced using solar energy. What is the primary source of this number? It may look small for a country India's size but I suspect it is incorrect and the actual number is smaller. Please correct me.

    4) The article mentions the Moser Baer Photovoltaic ltd plans to invest in a PV nanotechnology factor in Tamil Nadu. I have seen news reports this plan stands cancelled/postponed. Please correct me.

    5) Please substantiate the claim that solar PV production has already reached over 300MW. The impression is given that this is 300MW of PV cell production, not panel/module. Please clarify.

    I came back from India with the conclusion that the solar picture on the ground is a lot more dismal than made out in the article. I also concluded that the ambitious plans and low costs shown in the plans drawn up by the National Solar Mission (Solar India) this year, are more to get funds from the West in Copenhagen this year end than with any reality based plans to make Solar really happen in the country. Again, I hope to stand corrected through facts and figures. Thank you
