Polysilicon production capacity nikon battery

2010 is currently the world’s polysilicon production capacity will reach three times the

Restrictions on solar energy industry has been the development of polysilicon feedstock bottleneck will probably be broken after two years. Chen Jinchong energy analyst at UBS, said yesterday in Shanghai by 2010 nikon en-4, the global polysilicon production capacity will nearly triple, while China will be the world in the solar field as a leader.

“The current solar energy industry development is mainly constrained by the high cost of polysilicon. However, we expect that by 2010, global production capacity of polysilicon have reached the triple nikon en-el1.” Chenjin Chong said.

It is noteworthy that this part of the new capacity there is a considerable one from China. Chen Jinchong In an interview with Shanghai Securities News reporter’s question, said, “We expect within three years or so, China will build large-scale polysilicon production plant, using a modified Siemens technology. As a result, polysilicon production costs will decline to the current market-leading vendor of those levels. By then, China’s solar field will also become a global leader sony VGP-BPS18 , sony VGP-BPL18. ”

However, he also believes that the supply of polysilicon production capacity to meet its current three times does not mean that the bottleneck will definitely break. “It will depend on market demand. Because of the demand elasticity of PV market is still very large, it is possible as prices fall, will generate additional demand.”

However sony VGP-BPS19 , sony VGP-BPL19, the domestic photovoltaic industry leader, Zhengrong Shi, Suntech’s chairman had previously publicly stated that China is not suitable for manufacture of polysilicon country, because electricity is too expensive, producing polysilicon is not consistent with the scientific concept of development. In his view, the investment should go to polysilicon Canada, the United States, Australia, electricity is relatively inexpensive country.

Similarly, Chinese Academy of Sciences Jian Shui-sheng, has written that the current production of polycrystalline silicon business generally a modified Siemens France. Using this method, 1-kilowatt solar cell about 10 kilograms of polysilicon needs to consume energy 5800 ~ 6000 degrees, the power consumption is enormous. Even if the sony VGP-AC19V10 battery to be stable for 20 years, the solar cells to power is not renewable more than 8, a lower level.

But the industry was also disputes that. Last year, expected to start the 10000-ton polysilicon project LDK Chairman Xiaofeng Peng In an interview after interview with Shanghai Securities News said they used the technology do not consume so much electricity. Their short-term goal is to make the cost of photovoltaic power sony VGP-AC19V13 generation is cheaper than wind power.

Turning to the issue of cost-Chenjin Chong pointed out that, in fact, enough solar energy in some areas, solar power costs compared to traditional power plants have been very competitive.

According to him, the manufacturing cost of solar cells has the cost of conventional power plants is very close to the peak time. “And the cost of solar cells with the capacity to double sony VGP-AC19V19, but also decreased by 20%. And according to historical experience, but also achieve the annual cost for a drop of 5%.”

Recently published “China’s New Energy and Industrial Annual Report 2007″ shows that China’s current plans polysilicon production capacity of up to 63.56 thousand tons sony PCGA-BP1N, by 2008 can be formed about 18 thousand tons annual production capacity of polysilicon.
