Solar Farms or Giant Solar Power Projects consisting of thousand of solar panels installed on acres of land are increasing rapidly in the USA.While the European governments are discouraging the use of large installations of solar panels,the US is going the opposite way in installing these power plants.The US government recently approved of a number of Solar Thermal Power Projects worth several gigawatt recently.

I have been consistently writing that Solar PV has leapfrogged far ahead of Solar Thermal Technology in the last couple of years.The entry of the low cost Chinese with huge scale and the fall in polysilicon costs have suddenly made the future survival of Solar Thermal Technology suspect.The Solar Thermal Advantages of energy storage is also overrated because it is cheaper to add energy storage to Solar PV as the following article shows.Note Solar PV has many other advantages of Solar Thermal anyway.The Rapidly Declining Costs of Solar PV in fact pose a massive threat to all other forms of Solar Technology including Thin Film which has recently seen a number of players gone bankrupt.The recent conversion of Solar Thermal Plants by Tessera,the losses being made by Solar Millenium due to delays are further evidence of the decline and possible obsolescence of Solar Thermal Technology.

The Indian Government’s launch of the ambitious Jawaharlal Nehru National Solar Mission(JNNSM) was done with much fanfare with a target of reaching 20 GW of Solar Capacity by 2022 under 3 phases from the 81 MW currently.While the government had the best intentions and had laid down a well defined 10 year plan with subsidy support for both Solar Thermal and Solar PV Technology,it has already run into problems.Due to high interest the government went in for bidding of projects which led to irrationally low bidding from unknown firms.This has put the entire exercise in question with the the biggest private utility saying JNNSM is a failure.Without extensions of deadlines it looks highly unlikely whether the 37 winners will actually put up the plants.

While the major solar energy companies are expanding rapidly as the solar industry grew by almost 150% in 2010,a number of non-solar MNCs have gotten into this sector.The massive growth of solar industry which has been vastly underestimated by policymaker and analysts have not been hidden from these giant companies.While a number of these companies have been present since a long time,some are entering the growing solar energy field for the first time.Some like BP have lost the plot and become minor players despite being top companies a few years ago.Shell has totally left the solar energy field selling its plant to Motech.Asian conglomerates and semiconductor companies have been the most aggressive in entering this area.Chemical companies too have shown interest in building polysilicon plants which build on their core competence.Others have entered the Solar Thermal Energy Field which reinforces their traditional strengths in building power plants and EPC work.Here is list of the top non-solar companies entering the solar sector.

Crystalline Solar Cell Suppliers are fast disappearing due to the changing dynamics of the global c-Si Solar Panel Industry.With vertical integration becoming imperative as margins and prices get squeezed,independent solar cell suppliers are having a tough time.Increasing raw material costs in terms of higher polysilicon and solar wafer prices and competition from numerous players has decreased the number of pure play solar cell suppliers.However a few of the top solar cell producers continue to grow and flourish though they are also entering into other segment of the PV solar supply chain.Most of the independent solar cell suppliers are from Taiwan and some from China.European solar cell producers have mostly disappeared due to the high cost base of the European factories.Note this list is mostly composed of solar cell producers who don't have big module making operations.You can find a list of the top solar energy companies most of which make solar cells as well.

Solar Energy in India has a tremendous growth potential and is currently seeing massive interest.The government support in the form of JNNSM with a target of 20 GW by 2022 has given a sold impetus to solar power in the country.A small number of solar energy plants have already been completed by different developers in a small number of states.The migration projects of JNNSM are the first ones that are going to be completed followed by the ones which were won in the auction.Here is a list of current and potential future solar energy plants in India.

Asian Development Bank (ADB) may rescue the JNNSM process which seems to be headed for certain problems.The Bank is committing to provide loan guarantees for under 30 MW projects to Indian Banks and upto 25% equity investment into >30 MW projects.Note debt financing is a major issue which was talked about by the biggest Indian utilities for not participating.Note ADB has already committed to setting up 500 MW Renewable Energy Capacity in India in JV with NTPC.This will further increase ADB's exposure to Solar Energy in India.It remains to be seen if ADB give equity and debt to many of these projects which don't seem to be feasible at these prices.Will ADB willing to take losses in these ventures and provide loans to many of these unknown firms with no track record.

Solar Energy in India at the Federal Level is facing massive problems but the state level initiatives are pushing ahead.Gujarat has been at the forefront of promoting Solar Energy recently setting aside a 3000 acre site for 500 MW of Solar Power Generation.First Solar,the Cd-Te Leader and Producer of the largest number of Panels in 2009, has got an order from Acme Telepower for 15 MW Plant to be constructed in March 2011.Note First Solar is the also the lowest cost producer of solar panels in the world currently and looks to be so in the foreseen future as well.First Solar is expanding capacity by almost 50% in 2011 after a slow 2010 and looks upon India as one of its most important markets.

NextEra Energy Resources which was previously known as FPL Energy has bought a number of Solar Energy Generating Assets in the past few months.NextEra is the largest Renewable Energy utility in the USA with around 18 GW of Capacity out of which around 6.5 GW is Gas and 7.5 GW of Wind Powered Capacity plus 2.5 GW of Nuclear Energy.NextEra Energy with its long experience in Green Energy Generation has now decided to expand its Solar Asset Portfolio buying equity stakes in Solar Thermal as well as Solar PV Farms in USA and Canada.NextEra Energy is already the biggest Wind Energy Producer in the United States and on the way to become the biggest Solar Energy Producer as well.While Wind Energy is facing uncertain times in the USA,Solar Energy is growing at a rapid clip driven by the sharp fall in Solar Panel Costs which have more than halved in the last 2 years.

India's JNNSM Phase 1 which is targeting 1000 MW of Solar Power Capacity by 2013 is in jeopardy due to irrational bidding,financing and small size.The 150 MW Solar PV and ~500 MW of Solar Thermal Capacity which has been put to bidding is going to see massive discounts.This will eventually lead to project winners abandoning these projects or delaying it inordinately,leading to a failure of the first phase.India Solar Thermal Bidding has already seen Massive Discounts from the base prices of Rs 15.31 set by CERC and the Solar PV project bidding for 150 MW is going to see equally ferocious discounts.Tata Power,which is India's largest private utility is staying away from these auctions due to the above problems.Renewable Energy in India has a huge growth potential with Solar Energy the brightest Green Energy Sector.This has attracted companies in droves leading to hyper competition for the first phase of India's Jawaharlal Nehru National Solar Mission.However huge competition in this subsidy driven sector is not necessarily good for the growth of Renewable Energy as irrational bidding by small players would lead to project failures.

India has set up ambitious targets of meeting 15% of its Energy Needs from Renewable Sources up from around 5.5-6% in 2010.WIth India's Electricity Capacity expected to rise to 450 GW from around 165 GW,this would imply that around 67.5 GW of Electricity Capacity would be needed up from around 16 GW.This would mean around 5 GW of Capacity addition every year in the next decade which is a very tall order.20 GW could be met by Solar Energy according to the Jawaharlal Nehru Solar Mission (JNNSM).Most of the rest would have to met by Wind Energy.Biomass Energy has high costs and reliability problems which mini hydro potential is only 1 GW.Note this is just the capacity I am talking about,for meeting the electricity generation,capacity additions would have to be greater as Solar Energy and Wind Energy have only 20-30% Load Factor compared to 60-80% for Fossil Fuel Energy Sources.Nuclear Energy can contribute another 20 GW.
Renewable Energy in India is growing at a rapid pace increasing its share of the total capacity from 2% in 2003 to around 10% in 2010.However the share of electricity generation is still quite low at 3% due to the lower capacity load factors of Green Energy Sources compared to Fossil Fuel Sources.The Total Installed Capacity of Renewable Energy in India is around 16 GW with Wind Energy taking the Lion's share at almost 70% followed by Small Hydro at 15% and Biomass Energy at 12%.Solar Energy in India till now has a capacity of just 6 MW which is estimated to grow to 22 GW by 2022 making Solar Energy one of the Biggest Growth Opportunities in the Field of Indian Energy.

Boeing,the US Aircraft and Military Equipment Supplier had decided to sell its high efficiency solar cells in 2011.Note Boeing Subsidiary had created a record a couple of years ago with a 39.2% multi junction solar cell.These cells are primarily used in spacecraft where low space requirements require the use of high efficiency cells without major cost considerations.Spectrolab has continued to improve on the efficiency of the cells reaching 41.6% in a NREL Lab Test.Boeing has claimed a 60% marketshare of the space solar cell market and hopes to replicate that success on Earth as well.Boeing had earlier said that it would set up a 300 MW capacity by 2010 and market solar cells to CPV companies such as SolFocus.Will Boeing be Successful at Selling High Efficiency Spectrolab Germanium Solar Cells

The US Government has recently approved a number of Large Scale Solar Thermal and Photovoltaic Projects as Renewable Energy Projects rush to meet the December 2010 Deadline for getting the 30% Subsidy Cash Grants from the US Treasury.California has been leading the way with gigawatts of solar thermal plants being approved.However these projects are facing resistance from local groups due to different reasons.Green Activists are questioning the Environment Friendliness of these projects due to the harmful effects on endangered desert wildlife.While some projects have dedicated millions of dollars for the Rehabilitation and Resettlement of Tortoises and other wildlife,Green NGOs are not convinced.The 660 MW,$2 Billion Tessera Solar Thermal Plant has been put under a review of its approval due to protests that the approval was done with haste and without following proper procedures.Note Large Solar Thermal Projects need hundreds of acres of land and are being frequently built on public land.

Australia has shortlisted 8 projects with 4 Solar PV and 4 Solar Thermal Projects for its Solar Flagship Program which will be decided in 2011.BP Solar with 150 MW and Suntech/Infigen with 195 MW are on the shortlist.The other 2 companies are energy utilities which are proposing to use Cd-Te Panels ( I think from First Solar).Note both of these energy utilities are small and might face problems in fund raising and execution.The firms shortlisted for the Solar Thermal Projects don't inspire much confidence either.The selection procedure and how the subsidy will be disbursed has ran into controversy with accusations of bias and partiality.WA has not gotten any projects while Queensland province has gotten most of the projects.The firms shortlisted have also come under fire as they don't have much experience.Not much information on how the firms were shortlisted but these companies are definitely not the best or cheapest by a big margin.Australia has generally made a mess of promoting renewable energy with New South Wales cutting feed in tariffs sharply after giving an overly generous subsidy.The Solar Flagship Program looks like an expensive mistake in the making if it comes to fruition.

Solar PV Technology have made a huge advance in the last 2-3 years leading to a demand explosion with more than 100% growth forecast this year.Crystalline PV Technology as well as Thin Film Technology like CIGs and CdTe have reduced their costs drastically.While Solar PV still requires generous government subsidies for their growth,grid parity has come very close.Solar PV Technology has become economically competitive in parts of Italy where a unique combination of high electricity rates and sunshine have made Solar PV Technology very attractive.Costs are being reduced at more than 10% per year which would make Solar PV competitive in 2-3 years in most parts of the world.However mainstream and reputed forecasters and companies like Boston Consulting Group remain blind and ignorant to this.BCG in a recent report has said that biofuels and Concentrated Solar Thermal (CSP) Technology will become competitive.I have issues with both of these technologies.

California and the Federal Government have recently approved a number of big Solar Thermal Plants totaling around 2800 MW.These plants utilize Concentrated Solar Thermal (CSP) Technology and uses mirrors and towers instead of normal PV panels.The haste with which these plants are being permitted and approved is mainly due to the expiry of the Treasury Grant Scheme by end of 2010.According the the American Stimulus rules,only Green Projects which have broken ground or spent 5% of their costs would be eligible for the 30% Cash Subsidy.6 Huge Solar Thermal Plants have been approved with the biggest Blythe plant being the most recent.The capital costs for these plants are extremely high at around $6/watt which makes me question their economics.PV panels can be installed at around $3-3.5 /watt which is around 40-50% lower.Despite the higher capacity factors for Solar Thermal Plants and their ability to store energy for a short period,the cost difference is too large.

Solar Frontier is a subsidiary of Showa Shell Sekiyu and is listed on the Japanese Stock Exchange.The Company has big plans for the Solar Energy Market planning to increase its capacity by more than 10 times in 2011 to around 1 Gw in total.All its 3 plants are located in Miyazaki in Japan and uses previous plasma plant of Hitachi.Solar Frontier claims 11.5% efficiency for its CIS modules which are expected to go upto 14% by 2014.The Company is spending around $1 Billion in Capex for building the 1 GW capacity implying roughly $1 capex/watt which is not exactly cheap though not very expensive either.Note Thin Film Competition is hotting up with Saint Gobain-Hyundai,TSMC,Miasole,Oerlikon Solar,Sharp,Nanosolar all making plans for huge capacity expansion in the next couple of years.Solar Frontier has signed some small deals for supplying 1-3 MW in Thailand,Japan and Australia Recently.However the cost structure of the company is not known till now just like Sharp.While Solar Frontier looks good on the capacity and partnerships front,it has still to prove itself on costs to really push the Chinese Solar Companies which are dominating the Solar Scene right now with their low cost polysilicon panel production.Note 60% of the Solar Panel Production in Q210 was estimated to be done by Chinese based manufacturers.

Note Solar Panels prices differ widely depending on the technology,power,brand and quality.Thin Film Panels in general cost lower than crystalline silicon panels.Higher Power Panels have a higher price as they generate more electricity.Good Brands also have a higher price tag while cheap imported Chinese panels cost less.Solar Panel prices have decreased by almost 50% in the last 2-3 years and now sell for around Rs 1800-2500 per panel internationally and should fall to around Rs 1000 in the next 3-4 years . However for small installations on house of 1-5 KiloWatts,panels sold by distributors is more expensive and can cost you almost 50% more.Also Solar Panels form only a part of the total Solar System Cost.The total cost of installation,equipment and wiring can cost upto Rs 30,000/Kilowatt.

With most of the low hanging fruit of polysilicon costs already gone,the industry has to focus on efficiency to cut down on costs.Selective emitters,microinverters,DC-DC optimization and other technologies are already finding takers.A Number of microinverter companies like Tigo,Enphase Energy etc are tying up with global heavyweights like Suntech and Sunpower to increase their penetration and cut costs.National Semiconductor has also tied up with Suntech to integrate its products with Suntech Modules to improve efficiency and reliability.The Balance of Systems costs for Solar Panels and their Performance are not usually paid a lot of attention.But with every cent now making a big difference,these technology could make or break a company in this commoditizing industry.While the value addition and costs of these new products are still subject to market acceptance,its a major change for the industry.This is the next phase in the evolution of the solar energy industry as it looks to additional ways to cut costs and bring solar energy to grid parity.Look for M&A in this space as well since the industry is fragmented with a host of VC backed startups.

Although the global financial crisis has pushed governments to sharply cut aid to the renewable sector, it has had little effect on costs in the solar mirror power sector compared with the photovoltaic (PV) sector, which uses solar panels to generate power.
"We've see some reduction in prices, but nothing like in the PV sector. Costs per megawatt are between 4 and 5 million but they can reach up to six depending on the kind of power storage system you use," Seage said.
Sector analysts put the average cost of CSP per megawatt at about 5 million euros before the global financial crisis, about six times more than for conventional gas-fired power generation.
The high cost of CSP makes it unlikely to be competitive with conventional energy until the next decade, and that also depends on reasonable charges for carbon dioxide emissions.
"We see CSP power becoming competitive between 2020 and 2030, depending on a country's levels of radiation," Seage said.

Note the Solar EPC business typically is a low margin business like the general Enginereering Procurement and Contract (EPC) Sector.A number of Solar Companies like Q-Cells,MEMC,Sunpower and First Solar in recent times have entered this segment to generate a captive demand for their solar products.Nobody derives significant profits from this part of the supply chain due to its lower margin structure.With low barriers of entry and little bargaining power,this part of the Solar Food Chain is the last place you would expect a high technology company like Toshiba to enter.The Nikkei report says that Toshiba wants to enter the Smart Grid business by leveraging its experiece of the Solar EPC business.
