Taiwan Solar Energy Challenging China – Taiwanese Solar Cell,Wafer,Panel,Inverter Manufacturers following the Semi Success Path

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.

Why the Japanese Nuclear Accident should result in Huge Boost to Solar Energy

This Nuclear Energy Disaster in the Age of Twitter and Facebook will vehemently increase the opposition to the setting up of big Nuclear Plants.The Radiation Leak and subsequent health hazards will make it impossible for a Nuclear Reactor to be located except in very remote areas like the Sahara Desert.NIMBY protests are going to almost kill the Nuclear Industry in the next decade at least in democracies.The Nuclear Industry will take a long time in establishing its trust amongst the citizens.Without Nuclear Energy,the other major forms of Renewable Energy ,Solar and Wind Energy have to gain.Already Switzerland and Germany are deferring the planning and extension of Nuclear Energy.Other countries are putting safety reviews.Note the costs of environment regulation and nuclear waste disposal are already quite high.This will make new nuclear plants uneconomical as they are already facing huge cost overruns . Ask Areva in Finland and Constellation in the US.

Disadvantages of Wind Power – A Rebuttal as the Selfish Delay Wind Farms to Death

Wind Power has come under attack in the USA focused around the Cape Wind Project off the eastern shore.The project which was conceived over 10 years ago has not managed to still build the Wind Farm due to countless number of lawsuits filed for myriad reasons most of which are quite groundless.However some of the reasons have some solid facts behind the opposition to Wind Energy.Note Wind Energy unlike other forms of fossil fuel energy should have much less opposition however it is not so.Unlike Coal,Gas and Oil Energy it does not lead to increase in Greenhouse Gas Emissions and contribute to pollution.It does not lead to deaths of hundreds of miners each year nor has the danger of a catastrophic nuclear meltdown leading to death and disability of thousands.It also does not have the drawback of massive ocean pollution leading to an ecological disaster.However there are still protests against building of Wind Power Capacity and this article examines them in details.At the outset let me mention that advantages of Wind Power far outweighs the Disadvantages.

Japan Solar Energy – Future Growth driven by METI and 7 Zaibatsus (Sharp,Panasonic,Mitsubishi,Honda,Mitsui,Toshiba,Kyocera)

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.

Telecom Towers in India (GTL,Indus,Viom) Put Lipstick on the Diesel Pig – How Government can Prod them to move to Renewable Energy

India has around 300,000 Telecom Towers around the country , a large portion of which is not connected to the electricity grid.Another large portion does not have access to reliable electricity implying they have to install backup power systems in order to run without interruptions.Diesel Generators have been the choice of telecom operators despite their high carbon imprint.This is because of the ease of buying and installing diesel generators as well as the lower fuel costs as the government in India heavily subsidizes diesel.Note India's Fossil Fuel Subsidies have led to hundreds of distortions in the economy.Corruption,Pilfering,Adulteration is carried out on a large scale due to government subsidies.In fact a senior government official was burnt alive by the Kerosene Mafia a direct outcome of this subsidy policy.But that is a separate issue.

Rooftop Solar Energy in Australia sees a Boom leading to Subsidy Cut Pressure in Spain,Czech Deja Vu

Other states are looking to do so as well.Like other Solar Subsidy Programs elsewhere in Czech,Germany,Spain,Australia too has seen solar energy costs fall much faster than subsidies.This has led to a boom in solar installations as the returns become very high.These costs are ultimately passed on the customer electricity bills drawing howls from the states.Large Wind Energy Producers like Origin Energy have also seen the prices of RECs decrease so that is not feasible to build new wind farm projects.On top of all this confusion,the Australian government can't make up its mind on a Carbon Tax which will help it to meet the 2020 20% Green Energy Target.

France Solar Market becomes 7th largest in the world with 224% growth in 2010- To Double again in 2011

France has had a rocky relationship with solar energy.Unlike other European countries France gets a huge amount of electricity from renewable sources namely nuclear energy.Its electricity prices are one of the lowest and it even exports electricity to neighbors.So the driver for increasing solar electricity is quite low in France compared to others like Spain and Italy.However France has seen a massive boom in solar installations in 2010 making it the 7th largest market in the world.France installed over 720 MW of solar in 2010 and faces a massive backlog of applications.The government got overwhelmed and called a sudden stop to all applications.The French government stupidly blamed Chinese solar panels for the solar deluge when it was its faulty solar Feed in Tariff Policy which was too generous.

SkyFuel gets a CSP Contract in the highly protected Chinese Solar Market;Other Winners First Solar,eSolar yet to begin construction

Note China's Solar Market is a highly competitive and protected one with outside solar companies hardly having any presence similar to Japan's market.First Solar which signed a massive gigawatt contract to build a plant in Ordos has seen only delays as Chinese solar manufacturers opposed the plant.First Solar is still trying to build the plant signing a new JV with one of China's 5 big utilities.eSolar another CSP company got a contract to build a plant with China but till date construction does not seem to have begun there also.The Chinese government seems mostly interested in high-tech technology (First Solar,eSolar) rather than run of the mill players.Even these technology companies have failed to make much headway.Remains to be seen whether SkyFuel Succeeds.

More Evidence about Advantages of Solar PV vs Solar Thermal

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.

India Solar Subsidy JNNSM Guide – What you needed to know

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.
