China which is the world's largest provider of solar panels made from crystalline silicon is seeing a large number of smaller polysilicon companies go bankrupt or stop production. The reason is that for many of the smaller companies the price of polysilicon is $25-30/kg while the costs are $40-50/kg .This means that the smaller companies are making massive losses with the production of each kg of polysilicon. Note Polysilicon is a commodity industry like the memory industry and goes through periodic ups and downs when prices can go much below costs. In recent years a large number of companies set up polysilicon plants to benefit from the massive growth in the solar panel demand in Europe. However a massive glut in 2011 led the prices to fall across the supply chain of silicon solar panels. Poly prices fell from a high of $100/kg to $25/kg a drop of almost 75% in one year. This has made many of the smaller poly plants in China stop production as the price is below variable costs. The bigger producers like GCL , Renesola and Daqo have lower costs at around $25-30/kg which means they are breaking even . However for smaller companies the situation is dire as massive capacity expansion by the top polysilicon producers will continue in 2012 keeping prices at around the same level.

While US Solar Installers are making Hay while the Chinese Solar Panel Companies flood the world with super cheap solar modules,Western solar manufacturers are being killed at an astounding rate.The second biggest thin film solar panel company in the US United Solar Ovonic has gone belly up.The company was fighting a losing batter as the more efficient crystalline solar panel prices went below its production cost.The company had tried to fight in a the niche of BIPV solar panel market but could not survice. After First Solar,Energy Conversion Devices seemed the mostly likely viable company in Thin Film Technology.After a few quarters of profits in 2008,the company went into the red as its flexible a-Si modules failed to cut costs as fast as others.It has been shutting factories in the US and shifting to low cost locations.

However it has now thankfully put its plan on hold of spending another 520 million euros on solar energy. The company has already wrote down $1 billion in solar after the valuations of Ersol and Aleo have crashed from the time it bought it. Note most Western solar companies are going bankrupt as they can't compete with the 80c/watt solar panel prices. Stalwarts Q-Cells are defaulting on the debt payments while according to Total CEO, Sunpower would have been bankrupt if they had not bought it. Even the biggest US Solar Panel Company First Solar has been ravaged by the price war. Bosch has bravely said that it would continue to remain in the solar panel market while it makes more sense for them now to make an exit and concentrate on their core competencies. It can realistically never hope to get into the top 20 solar panel suppliers and stop spending good money after the bad.

We would like to incorporate BIPV solar tiles or roofing when we build - so we are trying to find out a this point what products are now available in Australia and what our choices would be and the range of prices each would be in ...just to give us a starting point as we begin to pull all the ideas together ?
We'd really appreciate any information you can send our way that would help us achieving this - the brand/type of BIVP we can use, the best inverter and battery you'd recommend - obviously it will depend on where we are and how much sun our roof will get - but we plan to make it as much as is possible as we'd like to be able create 100% of our power needs or if not at least 80 % . At present as a guide my household uses approx 10.7 khw of power a day - so that will give you an idea of how many solar tiles we'd need perhaps ...if the sun was at its optimum ? We hope to be building on a reasonably sunny block between Ferntree Gully and Belgrave on the high side near bushland ...beginning in a couple of months or so

So what are the criterea for staying alive in 2012
a) Government Support in Some Form - Most of the Tier 1 Chinese Solar Companies will fall into this bracket. However given that there are so many you would have to look at the biggest like Suntech, LDK, Yingli for survival in any case. LDK is a BANKRUPT COMPANY ,the only reason it continue to produce a solar panel is because of the Chinese government support
b) Low Cost - Though seems like an obvious idea, there are still companies existing which have high costs like Q-Cells, REC. You just can't invest in them given that even low cost is a necessary though not sufficient condition to survive
c) Branding - Very necessary to get financing for solar projects as without a brand you are not bankable and will have to sell at a 10% discount in a market which is already selling at below cost

First Solar the Big Daddy of Thin FIlm Solar Panels too is under pressure and if not for the DOE funded solar farms in California would have been facing a huge global marketshare loss. There are only a few thin film companies that can hope to compete . Those that can have big parents with massive balance sheets like Solar Frontier backed by Showa and Shell, Sharp ,TSMC and others . VC and PE backed startups have a snowball chance in hell of surviving because they need to get their costs to 50c/watt an impossibility even for First Solar leave alone poor startups.

The German Solar Energy Market is biggest in the world and has installed the largest number of solar panels for the last few years.2012 promises to be no different with Germany again set to the biggest solar market for solar panel manufacturers though Italy would give good competition.The German Solar Subsidy program has been the best in the world unlike the start and stop feed in tariff programs of Spain,Czech,UK,Australia and other places.A stable step in cut of feed in tariffs has helped solar energy prices coming down by more than 50% in the last few years though demand has only increased.

LDK Solar is one of the most insolvent companies in the world right now with billions of dollars in debt,a battered balance sheet,continuing losses and dodgy accounting.However LDK has acquired a German company Sunways and continues to build new solar power plants as the Chinese state owned banks continue to fund it with cheap money without any consideration about losing their investments.LDK has become the poster boy of the Solarworld complaint against Chinese solar panel producers as it continues to run and thrive despite being insolvent.The Chinese government is hurting itself and its other solar companies like Trina,Yingle which are more competitive by continuing to support and increase the global glut of cheap solar panels.These solar panels are being clearly sold at below cost as most of the companies would be bankrupt without these absurd loans which make no free market sense

Smaller Polysilicon producers with small sizes and higher costs are going bust almost everyday.With poly prices falling below $30/kg even bigger producers with inefficient plants like MEMC have been forced to curtain capacity.The smaller poly producers with 2000-3000 tons capacity have virtually no future.With poly expansion still taking place by big producers even in an oversupplied market the small fish are having the capitulate.

Sharp is the largest solar company in the world by revenues and has been so for the last few years despite massively increasing competition from Chinese Solar Panel Producers.While other Japanese conglomerates like Sanyo,Mitsubishi and Kyocera have substantially lost solar panel marketshare ,Sharp has managed to retain its leadership position.Though companies like First Solar and Suntech have shipped more solar modules than Sharp,in terms of total dollar sales Sharp is still on top.Sharp which used to make polycrystalline and monocrystalline silicon solar panels has diversified into producing thin film amorphous silicon solar panels.The company has also entered the solar IPP and solar development business in collaboration with Enel Green Power and by acquiring a US Solar Developer Recurrent Energy.However in core solar panel production,Sharp has much higher costs and has lost money consistently.Sharp sells Solar Systems and Solar Inverters as well as Solar Modules.However the challenges in the solar market are considerable with well funded low cost competitors from China and South Korea.Sharp faces the toughest years of its solar history as it fights to survive in this cut throat Solar Market

Building-integrated photovoltaics (BIPV) is integrating of photovoltaic modules into the building envelope such as roofs or windows.These solid-state devices are used to replace conventional building materials to generate electricity out of sunlight with no maintenance and help in fighting global warming as the produce no pollution.BIPV products are most useful in construction of new buildings as an ancillary source of electrical power, although existing you can retrofit old buildings with BIPV proudcts as well. The advantage of BIPV over normal standard PV panels is that they integrate into the buildings instead of sticking out leading some people to call it ugly.ALso they help in saving the amount of money spent on building materials and labor that would normally be used to construct the part of the building . These advantages make BIPV one of the fastest growing segments of the photovoltaic industry with some people estimating that the use of BIPV will increase at more than 50% annually over the next few years with more than 1 GW of BIPV modules installed in the last year.

BIPV is the acronym for Building Integrated Photovoltaics which means the integration of photovoltaic materials into building structures such as roofs,windows and facades.It not only replaces the building supplies but also generate electricity creating a killer green product.This is one of the fastest growing segment in the solar industry and it has been estimated that almost 6-7% of the solar industry is made of BIPV products.A wide variety of technologies and products are being used in creating BIPV products.Though a large number of big solar panel manufactures like Suntech,Yingli,Canadian Solar have come out with BIPV Panels and Products,the segment has not become as big mainly because of higher costs vis a vis the standard crystalline solar systems.There are also specialized BIPV suppliers such as Ascent Solar and Konarka whose products are more suited to the BIPV Industry than the normal module industry.Some of these suppliers have no option as their technology is no longer competitive with the Chinese solar panel producers.Solyndra had a niche product which could be used in rooftops with ease of installation and low weight.However the high costs drove it to bankruptcy.The next leg up to the BIPV industry should come up with more BIPV products from the Major Solar Companies and as cost of solar silicon decline further with scale and innovation

Solar Panels are fast becoming one of the fastest growing products for homes in the western world driven by the 75-80% reduction in the costs of solar panels in the last 3 years.The sharp reduction in the costs of solar panels has been driven by the improvement in efficiency of solar panels,increase in scale by Chinese solar panel manufacturers,solar equipment sophistication and advancements in the learning curveAlso the importance of Solar Energy keeps growing with the Fukushima Nuclear Disaster,Coal Mine Deaths,BP Oil Spill constantly reminding us the dangers of Coal,Oil and Nuclear Energy.On the other hand Solar Panels lead to no deaths directly or indirectly and are incapable of causing large scale disasters..Solar Panels these days are being made by a wide variety of manufacturers in different shapes and sizes.Different types of solar panels are also being made from different materials like silicon,CIGs,CdTe etc.Solar Panels are also finding uses in outdoor camping,boats,swimming pools,solar carports etc.Besides solar panels are also being used to power off grid systems in far off areas plus mobile phones and laptops.The advantages and uses of solar panels are growing by the day.Solar Power's greatest advantage is the declining cost which had made solar electricity from panels on par with grid retail electricity prices in places like Italy and Germany.With costs continuing to go down,its easy to see that solar panel generated power will reach the electricity prices in most places in the world in 2-3 years.

GE is one of the biggest companies in the world and has one of the biggest Green businesses as well.GE is the most profitable wind turbine manufacturer and is one of the largest renewable energy developers in the globe as well.GE like other electrical and power conglomerates like Siemens has decided to invest billions of dollars into Green Energy.Till recently Solar Energy had gotten scant attention from GE just like Siemens too has not invested a lot.However the 50% CAGR rates of Solar Energy,the fast declining costs have made it imperative for GE to have a presence in this market.GE had bought a thin film solar company Prime Solar a few years ago to acquire the Cadmium Tellerium Technology which First Solar uses in its Solar Panels.

Solar Panel Stocks have fallen off a cliff in 2011 driven by a massive oversupply in solar modules.The 2010 boom in solar energy demand led to rapid expansion by hundreds of established as well as new solar panel suppliers.This has led to a big increase in solar cell capacity.The demand in 2011 has not been enough to compensate for the massive increase in supply.Many of the higher cost companies in Western markets have already closed down operations with the news of a solar company closing down becoming a daily affair.The last time the wave of solar bankruptcies occured was during the 2008 Lehman crisis.At that time a few of the thin film companies had gone belly up as polysilicon prices had crashed.The sharp drop in solar panel stock provides a good time to enter the solar space as the valuations are at a historical low.Many of the solar panel stocks currently are being priced at a fraction of their sales and book value as the market expects almost every company to shut down.However solar demand is growing as the declining costs of solar energy is its biggest advantage.Also solar power growth is being vastly underestimated by policymakers and analysts.This short term pain is great as it provides a once in a lifetime oppurtunity to buy the solar panel leaders.

Japan was the largest solar market in the world till 2004,after which it was overtaken by Germany.The huge domestic market gave rise to Japanese companies like Sharp,Mitsubishi,Kyocera,Panasonic-Sanyo become top solar panel producers in the world.Mitsubishi the Japanese conglomerate with diversified global interests has a big presence in solar and wind energy as well.The company is known for its high quality panels and has a decent presence in USA and Japan.Mitsubishi is a part of the consortium which is looking to set up huge solar power plants in Thailand as well.But now with Japan reaffirming it commitment to renewable energy and on track to kill nuclear energy,Mitsubishi is turning its focus towards the domestic market.Mitsubishi is planning to set up a number of solar power plants in the country to take advantage of the Japan solar Feed in Tariffs which will be introduced soon

SunForce is a good marketer and distributor of solar and wind energy products,however it is not a manufacturer of these products.Buying Solar Panels from Sharp does not make too much sense as Sharp Solar Panels are expensive and on top of that you have to pay a margin to SunForce as well.SunForce Foldable and CIGs Thin Film 12V Solar Products also don't list a manufacturer nor do their solar inverters.SunForce does not look like the type of company who could make a technologically advanced products like a CIGs Solar Panels.You are better off buying charge controllers and solar panels directly from manufacturers rather than using SunForce.For some Solar Battery Kits SunForce might make sense as they have a good distribution.

Polycrystalline silicon or Polysilicon( poly-Si or "poly") is a material consisting of multiple small silicon crystals.The difference between Silicon Metal and Polysilicon is that Poly is highly pure form of silicon and is much costlier.Polycrystalline silicon can be as much as 99.9999% pure (also known as 4N pure,the 4 denotes the number of 9s after the decimal point).Polysilicon was primarily used by the semi industry till 5-6 years ago and the electronic industry used 9N pure polysilicon.The Solar Industry which has become the main user of polysilicon nowadays can do with 6N pure poly.
Polysilicon is refined to single crystal polysilicon before it can be used by the semiconductor industry.However solar cells can be made even from multicrystalline polysilicon.Monocrystalline solar cells on the other hand are made of single crystal polysilicon and have higher efficiency than those made from multicrystalline polysilicon.Polycrystalline cells can be recognized by a visible grain, a “metal flake effect”. Semiconductor grade (also solar grade) polycrystalline silicon is converted to "single crystal" silicon – meaning that the randomly associated crystallites of silicon in "polycrystalline silicon" are converted to a large "single" crystal.
