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.

Biomass Energy is highly under-appreciated as a renewable source of energy despite being the most important source of energy during most of human history..Biomass Energy still accounts for 1/3rd of Energy requirements in a lot of countries and is the primary energy source for heating and cooking in rural communities.Biomass Electricity accounts for around 1% of the world’s electricity capacity of around 5000 GW.With advancements in gasifier technology and energy conversion,biomass power plants have become quite popular.Biomass Power Plants are increasing in scale from around 20-50 MW to more than 100 MW as the technology has advanced quite a bit.The only problem for these large plants is securing feedstock for these power plants and storing them.Biomass energy is used mainly for cooking and heating in rural areas.Now it is increasingly being used to generate power as the technology for biomass energy has advanced.Biomass Energy like other Forms of Energy has got its unique Benefits and Drawbacks which are listed below

Climate Change and Global Warming have been put in the Cold Storage by most world governments as there is little will to fight one of the most pressing challenges facing mankind.With the successive Copenhagen and Cancun Climate Change Meets coming up as croppers,the Poor are left to fight the drastic affects of Climate Change in the face of Severe Weather like Droughts,Floods,Increase Sea Levels.Australia stupidly cut the funding for various Green Programs after facing one of the worst floods in the last century.It did not occur to the short term focused politicians that the Floods may have their root cause in Global Warming.Instead of increasing resources to fight Climate Change,they cut the Funding to help in the Flood Rehabilitation Programs

The strict environmental regulations of EPA is leading to converion of a Virgina Coal Plant to a Biomass Fired one.Note the US Congress and Senate have failed to move ahead on climate legislation remaining hopelessly deadlocked on any climate deal.Despite numerous draft laws,no common law has been passed as Republicans fail completely in understanding global warming remaining in the pockets of the powerful oil and gas lobby.EPA remains the only government body which is doing something to reduce pollution and at the same time fight for climate change.The strict new rules against emission of harmful gases like sulfur dioxide,nitrous oxide,mercury has forced a Virginia Coal Plant to convert from thermal to biomass.

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 .

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.

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.

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 Costs of Biomass Energy Production fall in a very wide range because of the wide variety of feedstock it uses.The costs of biomass energy also depend on the distance of the feedstock from the biomass power plant.Great distances lead to the biomass plant being unfeasible.Also some forms of Biomass are more expensive than others.Urban Waste and Waste Wood are some of the cheapest forms of biomass available.Similarly,Biomass plants also can be built over a wide range of investments.Co-generation plants or CHP plants are the cheapest biomass plants while standalone biomass plants which can use a variety of feedstock are quite expensive in nature.Note unlike solar and wind power,the investments in power plants based on biomass are not fixed.Some of the technology like boilers and turbines for generating biomass energy are common industrial equipment.The costs of a biomass energy can also depend greatly on how the feedstock is procured,managed and used up by a biomass plant.A good manager of a biomass plant is very important to lower running costs of a biomass plant.

Biomass Power Plants are increasing rapidly as the costs of fossil fuels go up and the need for renewable energy is increasing.Biomass Power is attractive because of its clean character and supplies a large portion of the energy needs in rural communities.With advancements in gasifier technology and energy conversion,biomass power plants have become quite popular.Biomass Power Plants are increasing in scale from around 20-50 MW to more than 100 MW as the technology has advanced quite a bit.The only problem for these large plants is securing feedstock for these power plants and storing them.Biomass Energy has a number of advantages over conventional forms of energy and depending on the feedstock cost can be generated at prices on par with fossil fuels.Biomass Energy also leads to higher energy security as biomass is almost always secured locally.

Moser Bear,the Indian Solar Company was one of the first customers for the now extinct Applied Materials a-Si SunFab Technology.The company had invested in a number of solar technologies quite early on,but has not managed to succeed in a single one much like the Abu Dhabi promoted Masdar.The Jack of all Trades strategy has come undone for both of these companies.While Chinese and some US companies have prospered despite stiff competition,most of the others have sunk.While most of AMAT customers have written off their investment in thin film equipment and factories,Moser Baer has not done so.But from its current action it seems to have given up at least in its thin film ambitions.Moser Bear has contracted for 25 MW of First Solar thin film modules.Note First Solar is the biggest thin film producer of solar panels and a direct competitor to Moser Baer.So it seems that Moser Baer has pretty much abandoned its thin film panels since if it itself does not use its own panels,don't think a 3rd party would do so.
