A lot of confusion exists about solar cells efficiency about which technology results in how much efficiency and the difference between solar cells and the solar panels efficiency.Note the biggest differentiator of a solar cell besides its cost is its efficiency.Not only do different materials give different efficiencies,even different companies have conversion efficiencies which differ for the same technology.Silicon Solar Cell Efficiency also depends on the purity of the solar wafer which is used as raw material to print solar cells besides whether it is monocrystalline or multicrystalline solar cells.With most of the low lying fruit already gathered in respect to lowering cost of the silicon solar cells,most of the big Chinese solar companies are concentrating their efforts in improving the efficiency in order to cut down costs in the cutthroat solar industry where the stars of yesterday are fighting to stay alive (Energy Conversion Devices,Evergreen Solar).This rising tide of the solar industry in 2010 has not been able to revive the fortune of some companies though European companies have made enough to fight another day.Solar Cells Efficiencies also differ in the champion cells tested in labs like NREL and on commercial lines.But here is a general range of efficiency of different types of solar cells made from different technologies
Solar Cell Efficiency Improvement is the best way to reduce the costs of solar power and reach grid parity in most places in the world.Solar Cell Efficiencies have improved continuously and with a number of companies and startups investing billions of dollars in research,it will keep improving.However cost considerations are an important factor as well and the technology which balances the two will win the solar energy race

Solar Water Heaters are one of the most successful solar products which have managed to proliferate without government subsidies needed for other solar products like solar panels etc.Note Solar Power in India is taking off with the government promoting its through the JNNSM subsidy policy.The payback period for solar heaters is quite short and it substitutes the need for electricity needed to run power guzzling water heaters in residential and commercial establishments.The other reasons for the success of solar water heaters is that they are relatively easy to build and install making them quite popular.China has the largest number of solar water heaters installed in the world and other countries are not far behind.India too has seen a rapid growth in the use of solar water heaters with roofs around India marked with solar water heaters.Note the government of India through MNRE also subsidizes the buying of solar water heaters making them even more popular.Solar Water Heaters of different qualities,capacities and prices are available in the Indian market.Solar Installers are responsible for doing the whole turnkey installation of solar water heaters,piping system and maintenance.

Spain has started cracking down on Solar Power Plants which are making huge profits through illegal Feed in Tariffs which they should not get.Note Spain had seen a massive boom in solar installations in 2008 due to unusually large ROI driven by high Feed in Tariffs.FIT are electricity rates which are higher than wholesale electricity rates paid to renewable energy power plants in order to make them competitive with cheaper fossil fuel power plants.Seeing a huge increase in the subsidy burden Spain has pretty much killed the solar market in 2009,however the problems of Fiscal Deficit has made Spain reconsider the tariffs being given to even older solar power plants.After a lot of controversy,Spain changed the FIT rules in the middle of the game through a retroactive FIT Law drawing howls of protest from solar investors like pension funds which have sued the government

Solar Power 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

First Solar Thin Film Leader and the largest solar company by value has decided to shift focus towards the commercial segment between 10-30 KW in size..The company was promoted by Wal-Mart promoters and has seen remarkable growth in the last few.This US based company uses Cadmium Tellurium (Cd-Te) Technology and is the lowest cost panel producer in the world today if you don’t include any penalty for low efficiency.Note First Solar derives most of its revenues from large utility solar power plants where the lower costs of its Cadmium Tellerium Solar Panels compensates for the Lower Efficiency of its Solar Panels.It does not get too many sales to the commercial and residential market where its lower efficiency panels lose out as they require much larger space to generate the same amount of power. First Solar Panels don't sell well in applications where space is a constraint.Note Sunpower which is the highest efficiency commercial c-Si solar module producer wins out in applications with space constraint.

Solar Power Plants have mushroomed in different parts of the world as Global Solar Demand has increased by more than 150% in 2010.Solar Power Plants built on the Ground differ from that put on the Roofs of Houses as they require to go through feasibility,environmental assessment,grid connection,siting etc. which is typical for a large industrial project.The time taken to build a solar power plant project is also much more than a rooftop residential solar installation.Solar Farms are being mainly being built in countries which have subsidy program like tax rebates,feed in tariffs etc.However building a solar plant has become quite easy unlike in the past as solar panel,solar inverters and installation expertise is more easily available.The regulations and permits for building a solar plant or a solar farm on the other hand differ from country to country and region to region depending on federal and state laws.For a Large Solar Plant like the Aqua Caliente,there are a number of permitting steps that have to be passed before the plant can be built.For smaller power plants in the 5 MW range the requirements are less.In general the smaller the size of the solar installation,the lower the number of regulations required.Here are the steps required in building a Solar Power Plant

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.

Wind Power in India forms the biggest Renewable Energy Sector in India with an annual investment of around $2.5-3.5 Billion a year and a capacity installation of around 1-2 Gw a year.The Wind Industry in India has shown tremendous growth to become the 5th largest global market by installed capacity which totaled around 13 GW by end 2010.With the government of India mandating a target of 15% from Renewable Energy by 2020 from 6% now,Wind Energy stands to gain immensely.A Number of Private Companies like Caparo,Technoelectric,KSK,Orient Green Power,Greenko have newly entered the Wind Electricity sector and are setting up hundreds of megawatts of capacity each.Wind Energy Companies in India have also rushed to set up Wind Turbine Equipment Manufacturing alone or in JV with foreign partners while Global WTG Companies like Siemens,GE are adding to their Indian factories as well.States like Maharashtra which are low on Green Energy Capacity are giving additional incentives and subsidies to promote the use of Wind Energy while low speed Wind sites are being targeted as well.
April 11, 2011
Wind Energy Companies in India were already facing trouble when China's largest power equipment producer and the 3rd largest Wind Turbine Manufacture Dongfang Electric won major Wind Contracts from Power Producers.Note Chinese companies have become the low cost leaders in the Wind Equipment Industry and sell much below Western competitors.Leading WTG companies from the West like Vestas and Gamesa are reeling from Chinese competition and slowdown in Western markets.Suzlon too has been affected as Korean shipbuilders and Chinese wind producers have become major players.India is the world's fifth biggest wind energy market and is expected to continue to build 1.5-2 GW wind power plants per year for the next decade.

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
April 11, 2011
Solar Power Plants till a couple of years were quite small compared to the mainstream energy power plants.Most power plants were in the double digit range with no Solar Farms having the capacity of 100 MW or greater.This is in reference to PV Solar Power Plants and not to Solar Thermal Plants which are bigger in size.Note Solar Thermal Plants by the very nature of technology require larger sizes to be economical just like Thermal or Nuclear Power Plants.On the other hand PV Power Plants do not gain much in economies of scale and government prefer giving subsidies to distributed rooftop solar installations rather than large solar farms.

A number of Agricultural Companies and Green Utilities are focusing on setting up biomass plants in different places in India.Note Biomass Energy accounts for almost 20-30% of the Energy Requirements of the country and is the main source of energy for most of the rural communities for cooking and heating.Biomass Energy is best suited where Crop and Animal Residue are cheaply available.Most of India's Biomass Power Plants have been built by companies involved in agri industries particularly sugar.Now Rice Companies are finding Biomass Energy perfect for their needs as they generate huge amounts of waste Rice Husk which can be used to generate electricity for their inhouse needs as well as for sale to the power grid.Note on top of this,Rice Biomass Electricity is also eligible for Subsidies from the State Governments.Haryana is seeing a surge in Rice based Electricity Plants with 16 MW installed already.Note Haryana is one of the top agri states in India alongwith Punjab and provides a lot of potential.Note a number of Rice Companies such as Lakshmi Energy and Foods have made Biomass Electricity a key part of their growth strategies even changing their names.Here are a couple of Rice Companies with aggressive Biomass Electricity Plans.

Coal is one of the most important sources of energy for mankind providing an easy way to generate energy in a cheap manner.The relative abundance and low costs of using Coal has made it the the first choice of Fuel for building Power Plants in the world.Coal has huge importance as an Energy source and forms the most important raw material for Cement and Steel.Coal is also used in a variety of other industries like Paper,Aluminium,Chemical,Transportation and Pharma.However Coal also has huge negative consequences as it is the largest source of Carbon Emissions which happen during Coal Combustion.Coal Mining despite two hundred years remain as hazardous as ever resulting in thousands of deaths in India and China.Mercury,Arsenic and pollution of other harmful substances into the environment causes diseases and many deaths as well.However for countries like India and China there are little other alternatives and there is no conviction amongst policymakers to change their energy strategies as well.So the advantages of Coal are currently overpowering those of the Cons of Coal.This despite Coal being the dirtiest form of Energy and causing many deaths globally.The main reason for the cheapness of Coal is that the societal costs are not added on explicitly to the Price of Coal making it seem artificially cheap.

Biomass Energy is the oldest source of Energy known to mankind and till the 19th century was the primary energy source.Even now Biomass Energy is used of Heating and Cooking by a large percentage of the Human Population.Biomass Energy with improving technology is being now used to construct large power plants.Growing Concerns over Climate Change and soaring Coal Prices are making some Power Plants convert from Coal to Biomass as a Fuel Source.Biomass Energy has many advantages such as being Carbon Neutral,using Animal and Crop Wastes in a useful manner,being poor friendly etc.However Biomass Energy like other Renewable Energy forms of Geothermal Energy faces problems of resources.However Biomass Energy suffers from some unique drawbacks like the problem of regular feedstock which becomes tough to acquire in times of drought etc.Biomass Energy also if not used appropriately can result in terrible air pollution as is the case with a majority of the Biomass Energy being used in the backward areas of the world today.Here is a list of the Cons of Biomass.

Coal is a dominant source of energy for humans accounting for almost for a quarter percentage of human energy consumption and majority of the global electricity production.However Coal is considered as the Dirtiest form of Energy as it leads to Air Pollution,Mercury Poisoning,Global Warming.Renewable Energy is considered as the solution with its non-polluting characteristics,energy security,freedom from peak everything.However Renewable Energy is way more expensive than Coal Energy making it difficult for Renewable Energy to take over Coal.However growing Global Warming Costs will weigh in the future making it inevitable that Green Energy catches up.Here is a list of the pros and cons of Green vs Black where Green represents Renewable Energy and Black represents Coal.Note Green Energy will ultimately win in the end,its only a question of how soon because if the realization comes too late then Climate Change might go far enough to cause catastrophic damage.

Coal is the Biggest Contributor to Global Warming generating billions of tons of carbon dioxide during combustion.Coal is one of the most abundant fossil fuels available on earth and it is expected that Coal will last another 200 years.The mass usage of Coal and its deleterious effect on the environment makes Coal a controversial choice of Energy.Coal is responsible for 25% of Human Energy Consumption and is the largest producer of Electricity in the world.
Coal causes Human Deaths in the Thousands each year directly through Mining Deaths and Indirectly through Human Diseases like Lung Cancer,Mercury and Arsenic Poisoning.The costs of Coal are artificially low because these costs are passed onto society and not explicity added onto the cost of coal powered electricity or coal products like Steel and Cement.Reducing Coal Usage gradually is a big necessity but given the growing hunger for energy by India and China and lack of a Climate Agreement that looks unlikely in the near future

Coal is one of the cheapest and most important sources of energy, responsible for 41% of electricity productionworldwide. In many important countries like India,China,Germany,USA,Coal is the primary source of electricity and energy.Other smaller countries also heavily rely on coal for example Poland 94% , South Africa 92%, China for 77% and Australia for 76%.Coal has played this a pivotal role in the development of mankind and his progress into the Industrial Age.Coal is an essential raw material and fuel for important global industries like Cement and Steel.Different qualities of Coal are used for different purposes.For example coking coal with higher carbon percentage is used in Steel Production while Thermal Coal is used in Production of Electricity.It was during the Industrial Revolution in the 18th and 19th centuries that demand for coal surged. Coal is responsible for almost a quarter of the global energy production,41% of the Electricity Production and more than 60% for Steel Making.Here is a list of the Major Uses of Coal
April 9, 2011
Coal is one of the most abundant fossil fuels available on earth and is a major supplier of energy.Coal is the largest producer of electricity in the world accounting for more than 40% of the global electricity production.This is expected to rise to 44% according to IEA.In the last decade global coal consumption has grown faster than any other fuel.Coal has many other important uses as well such as steel production, cement manufacturing 6 billon tonnes of hard coal and 909 million tonnes of brown coal were used with China accounting for almost 45% of the global coal consumption.Coal is also one of the largest sources of Carbon Dioxide Emissions as well responsible for double the GHG emissions from Oil.Coal is regarded as the dirtiest form of Energy due to high Carbon Emissions,Pollution,Hazardous Substances such as Mercury,Deaths due to Coal Mining etc.However the cheapness of coal,its established industrial base and abundance makes Coal indispensable in the Short Term just like Nuclear Energy.Here are the main Advantages of Coal

India's Wind Energy Market is the 5th largest in the world and is the biggest renewable energy sector in India (non-hydro).Wind Power forms almost 70% of the Alternative Energy Capacity in the country and will have an important role to play to meet India's target of 10% Renewable Energy from Electricity by 2020.Wind Energy is very cost effective in terms of cost and is approaching Gas Electricity Prices.Combined with the favorable tax treatment,accelerated depreciation,subsidies by different sates,Wind Energy has become the favored Green Energy Sector for investment by large private sector companies.Wind Power Plants are increasing in number and scale as larger companies like Caparo enter the Wind Power Sector.Wind Turbine Manufacturers in India are fast expanding capacity and investment to capitalize on this opportunity.Suzlon remains the Bid Daddy of the Wind Industry in India,however a number of foreign and domestic Wind Turbine Manufacturers are giving it a run for its money.Global Wind Turbine Leaders like Siemens,Enercon,GE have started Wind Turbine Equipment Manufacturing in India in recent times to lower their costs.Here is a list of the Major Wind Turbines available in India of different types and capacities from the various Different Wind Manufacturers.
April 8, 2011
Wind Power Plants has seen a phenomenal growth of around 33% CAGR in the last 5 years and the total capacity at end of 2010 was 11800 MW with most of the capacity installed in the state of Tamil Nadu which is the largest state in terms of Alternative Energy Capacity in India.GWEC has set an ambitious target of 65 GW for Wind Energy in India by 2020 which means an addition of 5 GW each year which seems too high given the wind power potential in India is only around 65 GW.However using low wind speed sites may increase the potential besides the use of offshore wind power in India.A number of Wind Turbine Manufactures in India have set up facilities attracted by the domestic market with Suzlon being the biggest Wind Company in India.
The Indian Wind Energy already has the 5th largest installed capacity in the world and is set to grow at a rapid pace driven by investments from the private sector attracted by the generous wind subsidies from the state and central government in India.Most of the Installed Wind Capacity in India is located in the southern and industrial states of the country.The other states like UP,Bihar lacks sufficient Wind Energy Capacity despite having high power tariffs and substantial electricity deficits.It can be said that Wind Power in India is being developed only in the progressive states like Gujarat,Maharashtra and others.To continue to grow at the same rate,the industry needs to diversify geographically but that would need the backward state governments to pull up their socks.

India launched its Solar Mission by the name of Jawaharlal Nehru National Solar Mission (JNNSM) with a lofty target of 20 GW by 2022.The Solar Mission has been divided into 3 phases and promotes solar energy installation,solar industry,solar heaters and off grid solar.Note the Solar Mission provides subsidies and incentives to promote the use of Solar Energy from the Central Government.Different States such as Gujarat have enacted laws to support solar energy on their own which is seperate from the Federal Target for Solar Power.I think the 20 GW target for 2022 is very low and will be easily exceeded but that is a separate discussion.The Solar Mission is not a rigid document but is a work in motion as the second and third phases will be implemented taking in the feedback and success of the first phase of the Solar Mission which has already announced the Solar Project Winners.
April 7, 2011
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.
April 6, 2011
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.
