Solar Energy is the only form of Energy whose costs are continuously declining compared to other forms of Energy.This is one of the biggest advantages of Solar Power over other renewable and non-renewable forms of energy.Solar Energy costs have declined by over 50% in the last 2-3 years even as Coal,Oil,Gas and other Energy costs have gone up.While Wind Energy costs have declined in the last year the overall trend is increasing as the costs of copper and steel go up.This is one of the main reasons why solar energy demand has gone up by 150% in 2010.With solar costs going down by another 10% each year over the next few years,expect Solar Energy to grow at a further fast rate in the future as well after growing at 50% CAGR over the last decade.Here are some of the advantages of Solar Energy over other non-renewable energy forms
There are only 2 Solar Energy ETFs in the Market right now – TAN and KWT.Note buying solar ETF provides a less risky way of investing in solar energy as some stocks can dramatically underperform in this fast growing industry.However Solar ETFs will on the other hand perform much worse than the best performing stocks in the solar universe.This is because their holdings are also concentrated on some of the lesser quality companies.KWT and TAN are better investments for the less informed and less sophisticated investors.Amongst the 2 ETFs,KWT is the better option than TAN for a number of reasons which are described below.
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.
Polysilicon or refined silicon is the raw material behind most of the world’s consumer electronics.Polysilicon is used to make both solar and semiconductor silicon wafers.Silicon wafers are used in making chips which are used by the Intels and Samsungs of the world while Solar Wafers are used in making solar crystalline panels used in generating electricity from the sun.Most of the world’s major solar energy companies used c-Si Technology in making solar panels.Polysilicon is an energy intensive process which requires cheap electricity.The polysilicon is produced mostly in the western countries like Japan,USA and Germany now.However the rise of solar panel producers in Asia has given rise to large volume Asian producers of polysilicon as well.Note Polysilicon production is concentrated in the hands of 8-9 companies unlike solar panel production which is done by hundreds of companies.This is a capital intensive process and requires around 2 years to complete a single plant.Semiconductors require higher purity levels of Polysilicon than the solar industry.The massive increase in demand from the solar industry has led to massive growth in poly production.Here are a list of the main polysilicon companies in the world
Solar Wafer Companies are mainly concentrated in Asia specifically China and Taiwan.Cheap labour,lower land and capital costs as well as presence of major customers has made China the No.1 Solar Wafer Producer in the world.Despite most of the polysilicon being produced in Europe and USA,China leads the way in wafer production.Note semiconductor wafers in contrast are mainly produced in the developed countries like Japan,USA and Germany.The structural forces of the crystalline silicon industry is forcing vertical integration with cell producers making wafers and wafer production companies making cells.However there are a few companies which predominantly concentrate on supply solar wafers to solar cell manufacturers.Here is the list of the main solar wafer producers which have shown stunning growth in the last few years.
Solar Thermal Technology has been facing tough competition from its sister Solar PV Technology in recent times.Despite strong government subsidies and support,numerous drawbacks have contributed to this Technology losing out to Solar PV in a number of projects in the US notably by Tessera.However a number of startups and big conglomerates continue to make huge investments in this technology.Spain and US are leaders in implementation of this Solar Technology type,however others like India and China are to building CSP plants as their energy needs continue to grow.Note like Solar PV,there are a number of different technology types for CSP like Power Tower,Parabolic Troughs,linear fresnel technology and Stirling Engines.Here is a list of the most important Solar Thermal Companies (Technology Providers cum Project Developers)
