makers of solar polysilicon stimulate industry

The major manufacturers supply-need help as that they invest in measures to improve the efficiency of conversion of crystals available locally. Cost savings are a bonus.

The world's largest supplier of solar panels, China continues to rely on imported despite polysilicon oversupply versions of national production. But the main actors of solar panels designed to change this situation.

Due to technical problems, the local variants do not transform energy as efficiently as their counterparts overseas facts. They are also more expensive. Thus, despite the integration polysilicon Germany or Japan, the solar panels from China cost about 10 percent less.

Now, a handful of Canada's leading manufacturers of solar panels are working to improve the quality of domestic crystals.

Yingli Green Energy Holding Co. Ltd., for example, is planning mass production of polycrystalline silicon using a silane method that has been reinforced internally. The process is said to be low electricity and reduce the polysilicon production costs between $ 25 and $ 35 per kilogram. Although this is still a bit higher than $ 22 to $ 30 per kilogram in the production costs factories overseas, the cheaper shipping costs and tax in China can cause a decrease prices in domestic polysilicon.

Meanwhile, Yingli, Suntech Power Holdings with, works to increase the power conversion modules, silicon monocrystalline solar energy efficiency by 16 percent to 18 or 19 per cent over the next three years. In comparison with the polycrystalline silicon single crystal is usually preferable to convert the sun's energy into electricity.

In addition, most large companies including solar panels are thin-film solar cells, which are supposed to be more efficient than crystalline silicon, in their own R & D objectives.

Solar Revolution in China

polysilicon plants in China started proliferation in response to the shortage the end of 2006, with about 40 new plants built between 2008 and 2009. These facilities, however, are not equipped with sophisticated equipment that will enable them to be on an equal footing with their foreign counterparts. Consequently, the output consists mainly of polycrystalline silicon in low-, most of which do not meet export requirements for the conversion of energy pollution emissions.

The advanced machinery and recycling technologies in factories overseas, meanwhile has resulted in lower costs while suppliers benefit from China has had. Chinese Renewable Energy Society Vice-President Jin Meng Xian said in factories abroad, only 150kWh is needed to process the crystals. In contrast, local factories consume at least 200kWh. In addition, manufacturing facilities in Germany and Japan can recycle waste and provide more than 99.99 percent pure polycrystalline silicon, something Chinese companies can not do.

Consequently, the price of a kilogram of polysilicon is $ 50 for versions $ 48 for local and imported variants.

Customs statistics show China purchased about 50 percent of polycrystalline silicon requirement Germany and Japan in 2009. For this year, about 1,000 tonnes are imported every month.

Connected to the UPS supplier Beijng Corona Application Science & Technology Co. Ltd., for projects of solar panels for a growth of 30-40 percent per annum for the next three years. levels of growth have driven up the cost of solar cells of 1.4 percent, averaging $ 1.42 per watt. However, this should not affect the prices of finished products, even if higher labor costs are factored in.

Shaanxi Double Wise Digital & Science Technology Co. Ltd, a solar lighting solutions, said citations have remained unchanged since 2004. His fire from the sea to the solar or the airport are still $ 73 to $ 118 set.

Xi'an Shengtang New Energy Co. Ltd. said the price of its solar lights will remain stable for the rest the year as well.
