Explicit subsidies to promote solar energy market growth rate of thin-film batteries

Strong policy-driven efforts

Ministry of Finance announced on the 20th of "the application of solar PV demonstration project construction guide declared," and specifically the three types of solar PV will be building applications for subsidies for demonstration projects, one building type, refers to the solar cell with the tile, brick, sheet , glass and other building materials together to become an integral composite building components or building materials, such as photovoltaic watts, PV tiles, roofing PV membrane, photovoltaic glass curtain wall,battery, such as photovoltaic roof lighting; Second, component-based, refers to together with the building components or stand-alone photovoltaic building elements as a component, such as a standard of ordinary photovoltaic components or custom in accordance with the requirements of the photovoltaic building components awning structures, shade structures, etc.; The third is with the roof, walls cover the installation type that is installed on the flat roof, sloping roof and the installation of overhead in the wall with the wall parallel to the form of installation. Subsidies for this year's standards, "Guide to declare" a clear, for building material type, component-based photovoltaic building integration projects, subsidies standard of no more than 20 yuan / W; with roof, wall construction combined with the installation of photovoltaic-based integration projects subsidy standard of not more than 15 yuan / watt.

Application of solar PV system cost of construction includes two parts, one component of the cost of solar cells in recent years, with the photoelectric technology and industrial enterprises expanded rapidly declining cost of solar cells has been reduced to 20 yuan / watts or less. Second, the cost of installing an application, including the design and construction, balancing system, such as grid access, in accordance with the construction using a combination of the different levels, the actual cost to install different applications, higher integration and higher cost of installing an application,ASM 92P1138, the current installation Application of the cost of an average of 20 yuan / W around. Subsidies in 2009 as the standard 20 yuan / W, or the current system costs nearly 50%. After the cost of electricity subsidies of about 1 yuan / degrees to enhance the competitiveness of the PV. The above-mentioned standards and international comparison of grants are in moderate levels, is conducive to better explore the mainland market.

Obvious advantages of thin-film FRU 92P1131

According to industry analysts, with the plan before the roof compared to the "Guide" of subsidies for further refinement criteria, specific to the batteries. Monocrystalline silicon, polycrystalline silicon, thin-film three is the more mature applications of solar photovoltaic cells.

The analyst said, but in terms of subsidies, subsidies for film batteries slightly greater intensity, because the thin-film FRU 92P1129 and components for building more such type, crystalline silicon cell walls can not be used, can only be applied to component-based or a combination of the installation type, benefit from the larger thin-film batteries.

Thin-film solar cell is one of the cost of thin-film ASM 92P1140 than crystal silicon solar cells have advantages. Thin-film solar cells in space is not only a greater reduction in costs, conversion efficiency can be close to crystalline silicon, thin film solar cell production cost is currently about 1.25 U.S. dollars / W, it is estimated that by 2015 the price of components can be reduced to one U.S. dollars / W below 1 U.S. dollars plus installation costs / watt, the entire system can be in two U.S. dollars /vcompleted loading, power generation costs about 8 cents / kWh, and the current average tariff of about 10 cents / kilowatt-hour is similar to that in electricity market been widely used is bound to occur.

"Than before the price of polysilicon has been a substantial decline in profitability of enterprises has been greatly compressed." Zhang Shuai said, "Film is a relatively new technology, the development of late than the polysilicon, it has a lot of cost advantage. Generally speaking, once each made to measure electricity, the use of polysilicon thin-film 40Y6795 cell than the cost several times higher. "

It is understood that compared to crystalline silicon cells, does not rely on polysilicon thin-film battery materials, power generation cost is therefore much cheaper. Polysilicon battery once reached the price of traditional thermal power of 10 times, but the price of thin-film batteries can be comparable to conventional thermal power prices, so thin-film battery is considered an alternative battery of crystalline silicon products, to develop a good prospect. Including Suntech, Jiangxi Zevi and the number of domestic listed companies, have entered the field of thin-film ASM 92P1132,ASM 92P1130,ASM 92P1128,FRU 92P1127, dell 6y270 ,dell laptop battery
Tak Base was built in Shanghai, and Legend Capital, IFC also has investments in film battery.v
