A solar cooker uses solar energy to heat food or drink to cook it . The vast majority of the solar cookers presently in use are relatively cheap devices though expensive devices are more prevalent in developed countries. Solar Cookers use no fuel and require little maintainance, they can help reduce fuel costs for the poor which are mainly depended on firewood for cooking.This will reduce pollution and lead to saving of the forests.
eSolar is a US based Solar Thermal Technology Startup which has managed to raise $182 million from top VCs and investors and managed to win contracts to build solar power plants using its properietary Power Tower Technology in the US,China and India.Note like Brightsource Energy,eSolar is one of the most promising CSP startups which has managed to get funding and contracts,it now needs to execute to deliver on its potential.
Solar is using the Power Tower Technology same as Brightsource Technology which differs from the parabolic trough mainstream CSP Technology.Note Parabolic Trough Technology is used by most of the established Spanish players like Abengoa.It is also the Technology used in the 392 MW largest solar thermal plant in the US built in the 1980s by Luz.In this technology thousands of heliostats (mirrors) reflect the solar light onto a “Power Tower” where water or salt is heated up.This heat energy is then transferred into Electrical Energy through standard Steam Turbines and Generators used in Gas,Nuclear and Thermal Power Plants.
America currently has a massive number number of startups in the clean energy industry and a lot of them in the fastest growing green industry that is the solar sector.However like startups in all industries a lot of them will fail,some will sell themselves to others like Heliovolt,Ausra while a few will make it really big making a fortune through IPOs for their PE investors and owners.One or two will make fortunes for those who invest early as well like First Solar.Note First Solar despite numerous ups and downs is still up more than 450% from its IPO price five years ago.It won’t be the last either.So despite the strong competition in the solar industry where numerous companies and technologies are jostling in the more than $70 billion global market,one or two of the smart ones will become huge winners like Intel or Microsoft.So which are the solar startups which are showing the most promise.Four of them are currently leading the pack while a few others have got a reasonable chance of success as well though they need to prove more like Stion and Miasole.Some of the more hyped ones like Solyndra have gone on a slimming down mode and might make a comeback though it will be tough.There are some others in stealth mode which may become big also.But here is the list of the Four Best Solar Startups in the Solar Electronics,Solar Panels and Solar Thermal Sectors.
Maharashtra which is the largest power generating state in India but deficient in renewable energy sources of generation will not use the discredited reverse auction bidding mechanism being used in the First Phase of the JNNSM Federal Solar Subsidy Policy.The reverse auction bidding was done due to the massive deluge of applications for setting up solar PV and solar thermal power plants.Based on the Rs 17.91/Kwh Feed in Tariff,developers had bid discounts with the solar project owner offering the biggest discount winning the right to build the solar power plant.This had led to irrationally low bidding for projects and it is all but certain that these solar projects will either be not be built at all or run into heavy losses.
India is a massively energy deficient country with official figures citing around 15% of peak electricity demand deficit due to lack of power generation and distribution.The […]
Note Big Oil and Gas has been slowly been retrenching form the solar energy industry despite initial leadership.Shell which was one of the biggest solar players has become almost non-existent while BP has shut down a number of solar factories outsourcing production to China.Other Oil and Gas companies like Exxon,Valero,Chevron and others have concentrated their energies on related green sectors like algae based biofuels rather than on solar and wind energy.So the move by Total comes as a surprise as it acquires one of the top 15 solar panel companies in the world.Sunpower is being acquired at a cheap price considering its world beating solar cell technology and its massive systems business which has gigawatts of solar projects under development.Note Sunpower makes the highest efficiency solar panels on a commercial scale and recently tied up with AUO.It is the 2nd biggest solar plant installer in the US and has a massive presence in the commercial and government sector.Total said it looked at over 200 companies before buying Sunpower.Note M&A has been strong in the Solar Thermal Industry and has now started picking up in the Solar PV Industry as well.With solar company valuations at a historic low,it makes sense for the larger chemical and energy companies to pick up good companies on the cheap.
India has a massive potential in Solar Energy with at least 20 GW of Solar Power to be installed by 2022 according to the JNNSM Plan.This […]
Solar Power in India is going to be one of the biggest opportunities in the 21st century with a number of favorable supply and demand factors converging.The Indian government too has supported Solar Energy in India through the ambitious JNNSM which aims for around 20 GW of Solar Capacity by 2020 (which is too low in my view).A Number of Green Companies both domestic and foreign have already made huge plans to capitalize on this oppurtunity.Here are some of the major happenings in India’s solar sector in the last month or so.Juwi which is one of the biggest solar energy developers in Germany ( a market which has become saturated) has joined hands with Lanco Solar ( a subsidiary of one of India’s biggest private power companies) to set up a 75 MW Solar Plant in Maharashtra winning a contract from the state power generation company Mahagenco.The contract value is Rs 884 crore which works out to be just under Rs 12 crores/MW or $2.6/watt which is extremely low even with the price of solar panels crashing in the international market.At this price the electricity generated won’t be too expensive and Mahagenco has a good deal.On the other hand Juwi and Lanco get bragging rights to being the development team for one of India’s biggest solar plants.
India’s JNNSM on the other hand has seen the first phase marked by a number of teething problems like debt financing,absurdly low bidding by noname companies,poor electricity infrastructure.The Second Phase is supposed to ally these problems but the first plans do not seem to be too great.The support for large solar farms will be increased from the current 5 MW cap to 20-25 MW cap.This will lead to only large investors,utilities and companies being left in the fray and lead to lesser competition.Also there is no support for rooftop solar which will help to broadbase the reach of solar energy.A Policy which helps distributed solar like Germany will do much more to boost solar in the country than supporting massive solar plants that will only help large companies making the most of the taxpayer subsidies.Note Delhi is the only state in India which is giing primacy to rooftop solar systems and is in the process of announcing a capital subsidy soon.The reason may be that Delhi mostly consists of urban homes and they have little option.
Solar Industry Mergers and Acquisitions (M&A) have picked up pace in recent times with a number of companies in distress with supply exceeding demand as Italy suddenly changed its solar subsidy policy in April 2011.With high inventory levels and prices crashing only the biggest and best solar panel manufacturers are managing to thrive.Note the Solar PV Industry has not seen too much M&A unlike the Solar Thermal Industry which has always been a hot area for M&A activity as giant industrial groups like Siemens,Areva,Alstom and GE have bought startups to improve their technology offerings.With the Solar PV industry having crossed more than $50 billion mark in 2010,more and more MNC conglomerates have now starting buying solar companies at cheap valuations.Here is a list of the recent buyouts,stake buys and mergers in the Solar PV Industry that have taken place recently.
Huge Solar Panel Projects are being planned in the USA by solar developers and utilities as solar panel prices have fallen by 20-30% in the second quarter of 2011 as solar panel manufacturers are faced with oversupply and inventory issues.Note building both coal and nuclear power plants in the US has become increasingly difficult with pollution and climate change issues coming to the fore.While natural gas is getting a boost due to cheap shale gas discoveries,solar energy is picking up pace due to the government support in the form of DOE Loan guarantees and Treasury Grant programs like 1705.Recently two very large solar panel projects have been announced or are in the process over the next 3-4 years.
Financing of Solar Energy Projects in India under JNNSM is proving to be a huge problem for the winners of Phase 1 auction under the federal subsidy scheme.Solar Energy in India has huge potential and attracted a number of companies to the first phase of the government tender under the 2020 plan to install 20 GW of solar energy.Note 620 MW of projects in the 5 MW and above category were awarded to 37 solar companies.Many of these firms had no background and had bid irrationally low to win these projects.With little experience and no established financial infrastructure it was an accident waiting to happen.MNRE offical has revealed that 18 of the companies have failed to achieve financial closure and would probably lose their license by the July 9 deadline.Note most of these bids were irrationally low and would not have made profits.Indian Banks and power financing institutions have refused to lend quite prudently.Note these companies are not putting collateral using their parent company’s assets which means that they too doubt the feasibility of their projects.Only huge penalties will deter future non serious participants as at least half of the solar power capacity won’t get installed in JNNSM Phase 1.It remains to be seen how this affects the future of the Indian Solar Mission.
Dye sensitized solar cells are next-generation solar cells based on innovative technology. Unlike conventional silicon-based solar cells, dye-sensitized solar cells consist primarily of photosensitive dye and other substances. A dye-sensitized solar cell is a low-cost solar cell. This cell is also known as the Gratzel cell & was invented by Michael Gratzel and Brian O’Regan. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. It belongs to the group of thin film solar cells.
Solar energy usage is an excellent, eco-friendly and cost-effective way to “Go Green”. It is a very effective measure to save energy & money. We use the solar energy every day in many different ways.Solar Energy is indirectly responsible for other forms of Energy that we use as well like Coal,Oil,Gas,Hydro Energy etc.The biggest use of Solar Energy is in Agriculture where Sun Light is used by plants to grow and provide food for us.Solar Energy despite many years of development is not used in the generation of Electricity due to its higher costs.However that is going to change as 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 forms just 0.1% of the the total energy supply of the planet currently and analysts and decision makers don’t think that Solar Energy can form a big chunk in the future as well.However I differ strongly in that aspect.The main reason for my very bullish opinion on Solar Energy is based on the simple fact that Solar Energy is the only form of Energy whose costs are declining rapidly on a secular basis.In a world facing the prospects of “peak commodity”,solar energy remains vastly abundant and it remains upto human technology to capture it at the lowest costs
Solar Air Conditioner or Solar AC refers to an Air Conditioner where the energy for the air conditioning is dervided from solar energy.There are 3 types of Solar Air Conditioning namely passive solar AC,solar thermal and PV Solar Air conditioning.Solar Air Conditioners though a niche area are expected to grow strongly in the future in hot areas like India where Air Conditioning is consuming huge amounts of energy and where there is sufficient sun light to generate big amounts of solar energy as well.
Solar Tracker is a Device which follows the movement of the sun as it rotates from the east to the west every day.Solar Trackers are used to keep solar collectors/solar panels oriented directly towards the sun as it moves through the sky every day.Using Solar Trackers increases the amount of solar energy which is recieved by the solar energy collector and improves the energy output of the heat/electricity which is generated.Solar Trackers can increase the output of Solar Panels by 20-30% which improves the economics of the solar panel project.
Solar Trackers are mostly used in ground mounted solar farms of capacity more than 1 MW.Note it is difficult to use solar trackers on residential rooftop installations.Horizontal single axis trackers are typically used for large distributed generation projects and utility scale projects. The combination of energy improvement and lower product cost and lower installation complexity results in compelling economics in large deployments.However for solar ground plants where area is not a problem,solar trackers can be easily be used.Also commercial and utility solar projects have dedicated maintainance teams which can easily repair and monitor solar trackers.The 20-30% increase in output easily compensates for the higher costs associated with solar trackers.Note Solar Trackers are especially useful in case of places where the solar insolation is high and the efficiency of the solar panels being used are high.Sunpower which makes the highest efficiency solar panels uses Solar Trackers in most of its ground mounted plants and sells solar trackers under its own brand.These days solar trackers are becoming increasingly important and major solar panel manufacturers like First Solar and Trina Solar are selling solar trackers as well.The selection of tracker type is dependent on many factors including installation size, electric rates, government incentives, land constraints, latitude, and local weather.
Solar Power in Australia has grown massively in 2010 and 2011 driven by state feed in tariffs also known as the solar bonus scheme or solar credits.This has resulted in the capacity limits being reached and most of the state solar subsidy schemes have been withdrawn (see the current state feed-in-tariff schemes below).However the Australian federal government is still offering the Renewable Energy Credit Scheme under which solar power generated is eligible to get solar credits which can be solar in the open market for cash.This will still drive the use of solar energy as the falling prices of chinese solar panels has made solar energy near electricity price parity in a number of places.Australia which gets a lot of sunshine is ideal for solar energy which promotes climate change mitigation as well besides reducing pollution.Australia has the highest average solar radiation of any continent in the world, which means solar industry has the greatest potential.

Amorphous Silicon Solar Panels were the big rage in 2-3 years ago when the prices of polysilicon the main raw material were touching $500/kg making the mainstream crystalline silicon solar panels very expensive.Amorphous Silicon (a-Si) on the other hand is a non-crystalline silicon which is deposited as an extremely thin layer on glass and other substrates.The cost of the silicon is much lower though the efficiency of solar cells which are made from a-Si is about half of those made from crystalline silicon.Applied Materials with its SunFab turnkey amorphous silicon (a-Si) equipment capitalized on this opportunity, lining up a number of customers with some customer orders in the range of a Billion Dollars.Oerlikon Solar was the other major thin film equipment market winning customers in Europe and China.Sky high poly prices also gave birth to numerous Thin Film startups planning to Manufacture and Use their own equipment rather than selling it .
Sun Power is the largest source of light in the is universe. It helps in providing food & oxygen for us, where sunlight is captured by plants in the process of photosynthesis. It helps maintaining the environmental balance by the continuous formation of vapours & condensation as rains. On a bright, sunny day, the sun’s rays give off approximately 1,000 watts of energy per square meter of the planet’s surface. If we could collect all of that energy, it could easily power our homes and offices for free. Other than these natural benefits, that the solar energy provides, it has many commercial usage too. Countries like Germany generate almost 20 GW of power from the Sun. Italy, Spain & Japan too generate a lot of electricity through the sun. Some of the smaller European countries like Czech,Belgium too are generating lots of solar energy through proactive Green policies.The bigger countries in the world like USA,China and India are slowly realizing the potential of Solar Energy and are rapidly increasing the amount of Solar Energy products. Solar Energy despite many years of development is not used in the generation of Electricity due to its higher costs.However that is going to change as Solar Energy is the only form of Energy whose costs are continuously declining compared to other forms of Energy.
Kaneka is a Japanese company which is present in a number of product categories like chemicals,functional and expandable plastic products, foodstuffs, life science products and synthetic fibers.However the main focus of the company is in Thin Film Solar Panels.Kaneka has been developing amorphous silicon thin film technology since 1980 and has advanced manufacturing into developing higher efficiency tandem microcrystalline silicon solar panels.The company also sells transperant see through solar panels.Note Thin Film Technology is facing existential threat from the rapid price reduction in the mainstream crystalline silicon technology which comprises about 85% of the global solar panel market.Kaneka sells its solar modules under the HYBRID brand name which refers to its hybrid tandem thin film silicon technology.Note other companies like Sanyo,Mitsubishi.Oerlikon have also developed this form of technology which gives higher efficiency solar panels as it captures a bigger part of the solar spectrum.
New Solar Panels and New Scientific Breakthroughs in Solar Technology it seems are reported every month.But Solar Energy is still not competitive with Fossil Fuel Energy despite its obvious advantages.The costs of Solar Energy are declining quickly but they remain still some way from being on par with the dirty forms of energy like Coal.The reason for all these new exciting technologies which are reported in newspaper not being able to bring a fundamental change in the energy scenario is that the costs are too high.Bringing a new solar panel technology from the lab to the factory takes a lot of time and effort.During this time the incumbent technology like crystalline solar technology keeps advancing due to the massive global R&D dollars that are spend and the rising scale.This had made many new startups in solar technology like Solyndra ,Spectrawatt and others bite the dust.You can read about the large number of solar failures in the first wave of thin film solar bankruptcies .
By definition it goes that Solar Energy is renewable. The sun rises every morning & sets every evening. It has continued like this since last billions of years & will continue for more billions of years. Hence there is an unlimited supply of sunlight. Unlike coal & oil which is fast depleting, there is an abundance of sunlight. Hence the prices of these products are getting dearer, whereas the solar energy will definitely be very reasonable in the near future. The day is not far off when all our homes & offices will be lit by this solar energy & that too for almost free.
Strictly speaking nothing in this universe is renewable but if the time-line of the energy source is sufficiently long for example in the case of the sun which will be billions of years then it is renewable.Solar Energy is definitely more renewable than Hydro or Geothermal sources of energy .
Solar Energy is the fastest growing industry in the USA and has been one of the fastest globally as well with solar demand rising by more than 150% in 2010 fueled by massive cuts in prices of solar panels especially those from China.While this has led to a major drop in solar energy stock prices this has also led to a massive boost in volumes due to demand elasticity.Only the top solar companies will be able to survive this brutal consolidation that is taking place with some companies like Solyndra already consigned to the death list.Solar Industry is a global one and has a big supply chain as well.This means that looking at only one stock market will deprive you of better opportunities that might exist in other stock markets.There is also a big supply chain associated especially with crystalline solar panels.There are companies that exist only in Polysilicon,Wafers,Cells,Modules.There are also companies that are suppliers of material like encapsulants and metal alloys to these industries.This article will give you a very broad idea on the complete list of solar energy stocks that exist in each part of the supply and different parts of the world.You can also look at the 2 solar ETFs that trade on the US stock markets TAN and KWT .
Solar ETFs are in the new because of a spectacular decline in 2011 caused mainly by the massive oversupply of Chinese solar panels.This has resulted in the two solar ETFs TAN and KWT making new all times lows.The main reason is the huge negative sentiment towards green energy stocks in general because of the lack of support towards climate change and over competition from Asian companies.However the Solar Industry is one of the best growth industries and the leaders who come out of this consolidation will have a bright future.You can see the 100 solar energy stocks to pick up what you think would be the leader.For less ambitious mortals you can look to pick up the TAN Guggenheim ETF which is the biggest solar ETF.You can also look at the comparison between TAN and KWT to decide on what to buy.Note Solar Energy’s biggest advantage is the falling costs of solar panels which is bad for the solar companies but great of solar demand and customers.When the weaker hands go out of business which is already happening (Solyndra),the solar companies that remain will make huge profits as they did in 2010 when demand surged by 150%.
Photovoltaic Cells have grown tremendously in the last few years spurred on by lowering costs and high demand in European countries like Germany.Photovoltaic Cell Manufacturers have also increased particuarly in low labor cost regions of Asia like China and Taiwan.In fact most of the solar panels have solar cells from companies in Asia.Solar Cell Manufacturers have incresased their capacity at a fast pace to meet the increasing demand.Currently due to oversupply of Photovoltaic Cells,the prices of solar cells have crashed with top quality solar cell prices almost 50% down from that one year ago.This is one of the best times to install solar cell panels in your roof given the rapid decline in the cost.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.
Photovoltaic Inverter or Solar Inverters as they are better known as have become one of the fastest growing segment in power electronics. The ~$2.1 billion market in 2009 with 7 GW of installations has increased by more than 130% to around $5 billion in 2010 as the solar panel demand globally increased to around 17 GW.Note Solar Inverter Companies have done much better as competition is much lower and the annual price declines in solar inverters has been much lower at around 10% compared to the 50% decline in solar panel in the last 2-3 years.Photovoltaic inverters are not being manufactured by hundreds of suppliers around the world though the top 5 solar inverter manufacturers control almost 75-80% of the market.The reason is that solar inverters have a high technology barrier when it comes to making highly efficient and reliable solar inverters.Till now Chinese manufacturers have not been able to significantly penetrate this solar inverter market because of this.In comparision Chinese solar module producers have captured more than 50% of the global solar market through cutthroat price and cost cutting leading Western solar panel producers like Solarworld to try and get dumping duties imposed on them.SMA Solar is the world’s biggest Photovoltaic Inverter manufacturer and is closely followed by US based Power One.
Solar Power Plants in the USA are proliferating with the falling cost of solar energy and the increase in government support through the Treasury Grant subsidy.Thousands of Solar Jobs are being created in the USA as solar installers increase their workforce to cope with the rapid surge in demand.The crash in prices of solar panels has led to increase in demand for solar system installations.Also the state Renewable Portfolio Standard (RPS) laws which make it mandatory for utilities to source a portion of their power from green energy sources has boosted the use of solar energy.Besides rooftop solar systems,large solar power plants are being built in the USA comprising of millions of solar panels with the help of DOE loan guarantees and 1603 Grants.Not only solar photovoltaic systems,but also solar thermal power plants which use solar heat to generate power are being built.Though some of the solar thermal power plants are now being converted to solar panel power farms due to their lower costs,still some solar thermal companies like Brightsource Energy continue to build massive solar farms.The list of solar power plants in the US is a constantly moving target but here is a list of the major solar power plants in the USA as well as some of the upcoming large solar power plants.Note this list is subjective as you can’t have a strict rule of solar system size to classify it a solar power plant.Also the huge number of solar installations makes it almost impossible to construct an exhaustive list of solar power plants.Here I am writing about the big solar power developers and their plans on developing large solar power plants.There are a number of smaller solar developers which I have not written about here.
Ladakh,one of the most beautiful hilly regions lying near the Chinese border has one of the highest potentials in generating solar power in India.Note under JNNSM,India is targeting more than 20 GW in the next 10 years and already large solar farms are coming in the desert areas of Rajasthan and Gujarat.However,Indian policy has mostly neglected the less inhabited region of Ladakh.Most of the policy initiatives have been low key in nature and mostly to provide the region with off grid solar power,solar cookers and solar lights.What has been missed is to build massive solar panel farms and connecting them with a transmission line to the power hungry states of the North.Just like Himachal Pradesh has become a masssive hydro power exporting state,Ladakh can do the same trick with solar power.
Solar Panel prices have fallen by 50% in 2011 and now solar energy can be profitably be generate at Rs 7/kwh.While this is more expensive than coal at Rs 4/kwh,the thing to be remembered is that this power value is constant for 25 years and it has no coal disadvantages which kills thousands each year.Also it increases Indias ‘energy security and reduce imports of expensive coal.It also will provide more employment and generate economic value internally beside supporting the Indian construction and EPC companies.
US Solar Projects including the 1000 MW Blythe Solar Project is now available for solar developers,installers at fire sale prices.The Insolvency Administrator is looking to sell parts and the whole of the solar project business of Solar Millennium and its US subsidiary Solar Trust of America.Note before filing of bankruptcy,the solar project developer had around 2000 MW of solar projects in the pipeline.
