Solar Lamps or Solar Lanterns have seen astounding growth in India driven mainly by the lack of access to electricity and the high costs of Kerosene or gas lamps.Note Solar Lamps have been so successful in India mainly due to their economic utility rather than their Green Characteristics.Note 100,000 Indian villages do not yet have electricity which means that the productivity comes to a complete stop in the dark.Poor schoolchildren cannot study in the dark and people cannot work in the night either.Note Kerosene a dirty oil refined product is the main source of energy for millions of Indian citizens.Kerosene is a health hazard resulting in accidental fires and causing a lot of smoke which can lead to various respiratory diseases.Note Kerosene is subsidized by the Indian government and distributed through the Public Distribution System (PDS) which is a massively corrupt and inefficient system.The Kerosene is given in limited quantities and is not sufficient to Light the Darkness for a month or more.The advent of Solar LED Lamps has been a godsend solution to this problem.

Solar Power in India is increasing at a rapid pace and will become one of the biggest energy industries in the next decade as falling costs of solar energy and India's rising demand makes it a perfect match.Solar Companies in India are constanly growing by the day as firms rush in to take advantage of the vast investment and profit potential in India's Solar Energy Market.BHEL which is India’s largest Capitals Good Company has big solar ambitions.BHEL has strong capabilities in the field of making electricity generating equipment.Extending these capabilities in the field of solar power generation is a natural extension.It is following the JV route with various other Public Sector Undertakings (PSUs) like HPCL,BEL and IOC to build power plants and solar equipment factories in the country.Most of these JVs have been dormant till now but the JV with BEL is now looking to move on.The JV is scouting for sites to build a 250 MW integrated c-Si Solar Factory which will also have India's first polysilicon and wafer manufacturing operations.Note India has a large capacity of solar cells and modules but does not have a commercial solar wafer or poly plant which are essential raw materials for making Solar Panels.Till now Solar Panels in India are made from imported Solar Wafers from companies like LDK,GCL,REC,Solarworld and others.There are a few private companies who are looking to set up upstream manufacturing in solar as well.Note there are other Indian government owned PSUs which too are looking to enter Solar Energy Industry as well

Meyer Burger (MBTN.S) the 6th largest supplier of solar equipment in the world jumped up 2 places by acquiring the 7th largest global solar equipment manufacturer Roth & Rau of Germany for a little over $500 million.The combined company will have revenues of over $900 million overtaking another Germany company Centrotherm with $825 million in revs.Note Applied Materials continues to be the market leader in the solar equipment market with $1.5 billion in solar equipment revenues just like it is the leader in the semiconductor equipment market.Note while European solar module producers have seen their marketshare and revenues crumbling in the face of the Chinese onslaught , there domination of the solar equipment continues. European Solar Companies had found things going tough in 2009 as the solar market changed radically with the Lehman crisis.As the prices of the raw material Polysilicon crashed and Chinese competition increased,these companies started bleeding red ink in a prodigious manner.The high cost structure of these companies with factories in Europe stood naked against the competition.With high debt loads,there was a high chance that these companies would go bankrupt.Most of them like Q-Cells,REC started to move manufacturing to Asia while Solarworld moved to Europe.

It is surprising to see the US Media jumping about saying the General Electric will build the biggest solar factory in the US when it is completely factually wrong.There are other companies that add 400 MW in a single quarter these days (eg.LDK). By the time GE builds its 400 MW Cadmium Tellurium Solar Panel facility,there will be around 20 players in the world with more than 1000 MW capacity.GE has been claiming high efficiencies for its Thin Film Solar Panels but the claims that it will be able to dethrone First Solar as the Leader seems far fetched currently.Note First Solar will have almost 7 times more capacity worldwide by the time GE builds its first solar panel facility.GE has been long been developing the Cadmium Tellurium Technology buying up Prime Solar.

Solar Industry is a fast growing exciting industry with its inevitable growth pangs as well.The first phase of India's Federal Policy has seen many hurdles and its success is in doubt,on the other hand Gujarat has managed to attract investment and power plants through a forward looking subsidy.States like Uttar Pradesh,Delhi,Maharashtra are also tentatively coming up with their own incentive policies.The Industry will see many ups and downs before it becomes a major billion dollar industry.Note Solar Power Industry has become the fastest growing in USA where it doubled last year and looks set to double this year again.The Nuclear Accident in Japan has given fresh energy to Solar Power with China set to double its target to 10 GW by 2015.

Solar Energy in India represents one of the best Energy opportunities in the 21st Century.However the growth at least in the initial stages will be geographically unequal.This is due to the fact that Solar Power requires strong government support and subsidies currently.The Indian Federal Government has already given it a strong push targeting 1000 MW by 2013 and 20 GW by 2022 under the JNSSM.While the Subsidy Program is facing some initial hurdles due to debt financing and aggressive project bidding,individual States are forging ahead to push Solar Energy on their own.Gujarat has been a trailblazer in this regard with The State has already recieved proposals for setting up around 365 MW of Solar Power.Gujarat through its own RPS and Feed in Tariff incentives is targeting 1000 MW by 2013.Rajasthan too is trying to exploit is massive solar insolation potential but its state policies have little clarity or direction yet.The state has signed around 1524 MW of Solar Project with 49 Developers.The Solar Policy Draft Proposal is mostly vague with a target of 10-12 GW in 10-12 years with around 500 MW in the next 2-3 years.Rajasthan is set to see massive solar installation despite its government's vagueness from the Federal JNNSM subsidy.Other states in India like UP,Delhiand Maharashtra have recently started making some moves but remains to be seen how good they are at implementing.While the UP solar subsidy is clearly quite ridiculous,Delhi seems to be on the way to implementing a smart policy of promoting small roof top solar residential installations.

PV Solar Cells or Photovoltaic Solar Cells are the building blocks of Solar Panels which are used to generate electricity from the Sun in residential or commercial establishments.Solar Cells are made of crystalline silicon the same substance that is used to make semiconductors which go into making of electronic products.Note Thin Film Solar Cells are not found for practical purposes as Thin FIlm Solar Production generally is a one step continuous process in which the whole solar panel is produced.On the other hand c-Si production is a 5 step process in which Solar Cells is the intermediate product of the 4th stage and goes as input to making of solar modules/panels.Solar Cells can be bought and made into Solar Panels as PV Solar Cells don't have much of a standalone usage.Note Buying Solar Cells and making DIY Solar Panels does not make much sense as it adds little value and does not save money.You are better off buying Solar Panels from affordable solar panel manufacturers.

Economically also Solar Panels are starting to approach retail electricity prices in number of places in the world.Large scale solar power plants are already selling power at 10-15c/KwH which is lower than the retail electricity prices in most places.Still competition between solar panel manufacturers,improving technology and scale are making solar panel costs come down at a rapid pace.In fact Solar Panel prices have declined by more than 50% from 2008 end to 2010 and are expected to fall by an average rate of 10% in the coming years as well.However Solar Panels are seldom bought by the customers directly but are rather bought by the solar system installers/contractors.However its a good idea to know about the costs of solar panels and systems that you are paying for and not get fleeced by unscrupulous solar installers.

Solar Industry is one of the fastest growing industries on the planet and the number of companies in the industry have increased dramatically attracted by the strong growth prospects and low entry barriers.The easy availability of solar producing equipment and low capital requirements for small companies have led to a mushrooming of the number of players in the industry.Its possible to set up a small 30 MW module production factory for as low an investment as $10 million or lower.Though the value add of a pure play solar panel production factory is low and the competetive position quite questionable nonetheless there are hundreds if not thousands of such small module producers in the world right now.Other parts of the crystalline silicon supply chain have also got a number of players though the technology and captial requirements are much higher.Listing out all the solar companies in the world is a difficult task and somewhat useless as well as many of these small scale solar companies will not exist in a few years as competition keeps intensifying.Consolidation in the solar industry will ensue sometime or the other and lead to a much smaller and sustainable industry.

Solar Panels Efficiency – Range,Technology Dependence,Companies with Highest Efficient Solar Modules
The Companies that make the Solar Panels with the highest efficiences are Sunpower and Panasonic/Sanyo.Sunpower has the highest efficient solar modules in the market using a properietary process and has solar cells with efficiency reaching a top limit of 24%.Sanyo also has very efficient solar panels under the HIT brand name.These solar panels also approach the 18% range (solar modules not cells).Normal crystalline plain vanilla solar panels come in the range of 13-14%.Note solar modules have lower efficiency than solar cells as some area is left for the frame etc.There are other companies that are fast catching up to Sunpower and Sanyo in the high efficiency solar panels as well.Note higher efficiency solar panels sell at higher prices per watt as the require lesser area.AUO which has a JV with Sunpower has recently claimed to have produced the higher efficiency solar panel .

India's Green Companies are seeing tremendous growth backed by the nation's massive energy demand increase.The 8% Plus Economic Growth coupled with the already massive electricity deficit which makes brownouts of 8 hours a day normal in many places in the country provides the macro background underpinning the growth.India's Green Industry is still in a nascent state compared to the massive solar and wind industries in countries like China and Germany.However attracted by the massive potential a number of companies small and large have entered the fray.Most of India's large energy groups,utilities have already established a small presence or are in process of doing so.While Wind Energy is the largest Renewable Energy Industry in India after HydroElectricity,Geothermal Energy is non-existent without a single large commercial plant.Biomass Energy is quite well developed and Solar Energy is the fastest growing Green Industry.Here is a comprehensive list of the Green Companies in India operating in the different Alternative Energy Sectors.

Solar Roofs are a niche area but is growing in popularity with the entry of more and more companies selling products tailormade for this area.What are Solar Roofs exactly - does it mean a Roof with Solar Panels installed on it or something else.Solar Roofs are not roofs where solar electricity is generated by putting in solar mounting/racking systems and mainstream solar panels,rather they are roofs where specialized solar products called solar shingles are installed.Solar Roofs can also mean a roof where Building Integrated Photovoltaic products are installed.Some companies make BIPV products like flexible solar panels or organic/dye solar cell panels ( these are niche companies).

Sharp is the biggest company in the world in terms of making revenues from sales of solar panels so it seems counterintuitive for someone to recommend not buying Sharp Solar Panels.However this Japanese Conglomerate has been losing marketshare rapidly to cheaper Asian competitors.Sharp due to its factories in high cost locations makes solar panels at a much higher cost and sells them at much higher prices as well.The reason is that they manage to sell so many solar panels is that consumers are not educated about other better options and the other solar panel companies don't have the distribution networks.Note Sharp has been trying to diversify away from crystalline solar panels to thin film solar panels.The reason is that they are losing the competitive advantage to Chinese companies like Trina Solar and others.

Solar Panel Manufacturers globally have kept on increasing due to the fast growing nature of the industry and low entry barriers.However most of the solar panel manufacturers have high costs and low quality.Most of these producers have little growth prospects and are a bad choice to buy from as they might go bellyup.This would lead to a void of the 25 year warranty of the solar panels.So it makes sense only to buy from the biggest and best solar manufacturers in the world.Solar Panel Manufacturers are present in most parts of the world with Korea,China,Taiwan,USA,Japan and Germany dominating.However small solar panel producers are also present in most countries like Spain,Greece,India etc.Solar Panels are of mainly 2 type - crystalline and thin film.Most of the solar panels produced today are of the crystalline type and are mostly used in residential rooftops.Thin film panels are mostly used in large ground solar power plants.Thin film solar panels are of lower efficiency and are lower priced as well.However falling costs of crystalline solar panels has led to their increasing dominance.
March 29, 2011
Cheap Solar Panels are widely available with the entry of a multitude of Korean,Chinese and Taiwanese companies.Most of these solar panel manufacturers are fighting on price and have decent quality.With little to differentiate between solar panels made by different firms,cheapness has become the main selling point for these solar panels.Cheap Solar Panels can be bought by an informed customers as expensive Western and Japanese brands still hold a large marketshare.But buying these brands might not make sense economically or environmentally.You can easily avoid buying solar panels from BP Solar because they outsource manufacturing of their solar panels to cheaper locations.It is common sense to buy cheaper solar panels from the companies located in those low cost locations.

Free Solar Panels don't exist just as Free iPads don't exist.Some websites and companies advertize free solar power or free solar panels based on government subsidies.Note even these free solar power offers are not completely free as they have a payback periods depending on how much government subsidies are given.Nobody is going to give you a free solar panel or a free iPad without a catch.

British Petroleum (BP) the multi billion dollar Oil and Gas Conglomerate is a strange player in the Renewable Energy Sector of Solar Energy.BP was a dominant company amongst the top 10 global manufacturers of solar panels till a few years ago.However the lack of interest on the part of management,low investment,lack of R&D has made it a bit player in the fast growing solar panel market.Companies which did not exist till a few years ago have outpaced BP to become top solar panel producers.However BP Solar Panels continue to sell in a number of market because of existing sales relationships and brand name.However it is only uneducated and uninformed consumers who are buying BP Solar Panels in my opinion.BP Solar Panels should be avoided both from an economic point of view and from the environment perspective.

While Chinese pure play solar panels companies have already captured a majority of the global solar module market,the entry of newer Chinese players into the solar energy market refused to stop.China's 5 largest state owned utilities have already made their presence felt in the Chinese domestic solar installation market by bidding extremely low to win projects under the Chinese Solar Subsidy program.Automotive companies like BYD have also announced a big investment into solar panel manufacturing while Hanlong and Bluestar Groups have decided to invest in the CPV and Polysilicon sectors respectively.
March 19, 2011
German's Solar Energy Market is the biggest in the world by a fair margin.Germany installed almost 6 gigawatts of solar panels in 2010 taking the total installed capacity to almost 16 GW which is 40% of the world's total installed solar capacity.Note Germany's Photovoltaic Solar Electricity now forms almost 10-15% of the total electricity production in the country at peak time.Note Germany's solar industry got a renewed boost when 7 old nuclear plants were shutdown following Japan's Fukushima Nuclear Disaster recently.Previously Germany had decided to extend the operating life of its Nuclear Plants despite stiff opposition.Germany Solar Subsidy which is framed under the Renewable Energy EEG law has made Germany one of the world's leaders in Wind,Solar and Biomass Energy.Germany's Manufacturing Industry has benefited from the strong domestic market with many of the world's top solar panel companies located there.Solar equipment,inverters and cell companies are also present in large numbers.Recently Germany amended its Feed in Tariff Law to slowdown the exponential growth in solar panel installations.This is over and above the regular reduction in solar subsidies done each year.

The Taiwanese Solar Industry has become the 2nd largest in the world following in the footsteps of China.Taiwanese Solar Industry has a longer history than the Chinese with Solar Cell Makers Motech and E-Ton establishing themselves globally way back in 2006.However the steep fall in solar panel prices following the Lehman crisis had led to losses for these companies as the Chinese companies surged ahead using their low cost manufacturing.The crisis also led to the emergence of newer Taiwanese companies like Gintech,Neo Solar which are growing at extremely fast rates.Note Taiwan is a hub of semiconductor manufacturing with leading companies like TSMC,AUO,UMC,HTC etc.Solar Industry uses many of the same technologies,raw materials and techniques common to semiconductor and Display Panels Production giving Taiwanese firms a natural advantage.Taiwan has been predominantly present in the crystalline Solar Cell part of the supply chain and lacks a big manufacturer of polysilicon ( though a facility has been started).The lack of vertical integration has also made the costs of the Taiwanese industry higher.The entry of large companies like AUO,TSMC has further increased the competition in the Taiwanese market.Note Taiwan's government has also promoted the use of solar energy in the country through the use of a Feed in Tariff program.

The South Korean Government is the Greenest government in the world without a doubt.The Korean government not only implement the biggest green stimulus but has also heavily promoted the use of Green Industry in Korea and amongst its industries.As a result South Korean Chaebols like Samsung,LG,Hanwha,Hyundai are making massive investments into Wind,Solar,Tidal,Nuclear Energy and Elective Vehicles,Batteries etc.A common theme running across these companies is their strong investments into the crystalline silicon solar supply chain.Hanwha has already become one of the biggest manufacturers of solar panels in the world by acquiring Chinese producer Solarfun while OCI Chemicals is set to become the biggest producer of polysilicon in the world.South Korea has also one of the most generous Solar Feed in Tariff Programs in the world to encourage solar panel installation in the country.While the subsidy ran into a hiccup,Korean Solar Energy is set to grow again as the government pushes Solar Energy Strongly.Here are a list of the major Korean Solar Companies.

CPV companies have recently started winning some utility scale power plant projects in recent times with Amonix wining a deal to supply 30 MW for a project being built for Xcel Energy.Now speciality wafer French company Soitec subsidiary Concentrix has won a massive 150 MW solar plant order from Tenaska Solar Ventures to produce 150 MW which will be supplied to Californian utility San Diego Gas & Electric under a PPA signed earlier.Note California has a RPS to generate 33% of its electricity from Renewable Energy Sources.Soitec will also build a new factory in the San Diego region to manufacture its proprietary CPV modules with 200 MW capacity.Note this will be the largest CPV plant in the world when built by 2015 much bigger than any CPV plant on the drawing board right now.This also pushes Soitec ahead of the other US CPV companies like Amonix,Solfocus

Solar Energy in Japan has a long future dating back to 1994 when the government introduced capital subsidies to boost solar energy installations on rooftops.Till 2004,Japan was the largest solar market in the world after which it was overtaken by Germany.After 2004,the growth in the solar industry tapered off as the government reduced the subsidies for solar panels to almost zero.The huge domestic market gave rise to Japanese companies like Sharp,Mitsubishi,Kyocera,Panasonic-Sanyo become top solar panel producers in the world.However the low cost Chinese solar module producers have pushed back most of the Japanese companies.Since the last year,the Japanese government has again started giving generous solar subsidies and feed in tariff to boost the renewable energy production in the country which remains far off targets.This has led Japan to become the top non-European market after USA and the growth seems set to continue in the future as well.Japan has relatively low installations costs and is much nearer to grid parity.Also lack of wind energy makes solar energy more attractive as a renewable energy choice.While large scale solar installations in Japan are almsot absent,there remain large numbers of rooftop solar installations.

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 Thin Film Technology has been growing rapidly despite falling costs of the mainstream Photovoltaic Crystalline Silicon Technology.While a number of Weaker Hands in Thin Film have downed shutters,Thin Film Producers continue to grow and expand.The massive growth potential of Solar Energy makes it possible for both of these PV technologies to flourish.Thin Film Technology unlike c-Si has a number of variants.Amorphous Silicon (a-Si),Copper Indium Gallium Sulphide (CIGs) and Cadmium Tellurium (Cd-Te) are the 3 main types of Thin Film Technology.There are a number of manufacturers of all of these 3 types of Technology.CIGs Technology is said to have the most potential in improving efficiency and competing with c-Si,however Cd-Te is currently the top dog as the world's biggest solar producer First Solar currently uses this technology.a-Si Technology is not that hot with low efficiencies however Oerlikon and Sharp are pushing ahead with developing this technology.Here is a list of the world's top Thin Film Companies.
