HC Chemical Network Information, as the main raw material PV modules, our polysilicon production capacity is the problem of excess recent rise has been widespread concern. Ministry of Industry, National Development and Reform Commission in the "2009 China Industry Economy Run Summer Report "noted that solar, wind and other emerging industries duplication, launched a very serious disorder. Many industry experts say that large-scale use in China has not said where solar energy solar energy can not explain the excess material.
International Financial crisis After the outbreak of polysilicon on the international market price fell sharply, in this case, the domestic PV industry investment enthusiasm is in no way diminished. "At present, China's polysilicon industry, there are quite a mixed bag indeed, Nishajuxia the situation." Analysts believe that the only real Mo Qingchu China's chassis, and to ensure the orderly and efficient development of polysilicon industry.
Production and up to completely different products
"Project put into operation in many cases, the polysilicon industry, overcapacity is a foregone conclusion, but the actual output is no surplus." Largest polysilicon manufacturer Lvjin Biao, deputy general manager of Jiangsu in to explain that "polysilicon manufacturers like Chemical industry Business, production, and up to completely different products, from production to reach capacity some time debugging. In other words, the design capacity of 1,000 tons of projects, short production is difficult to reach about 70% yield. Technology level is relatively sound company, reaching yields of only about 80%. "
Familiar with the polysilicon industry, people know that businesses ton polysilicon production line about two years construction period, running up to a year and a half to produce the good. Sichuan Xinguang 2007 began production of 1260 tons production line, the 2008 annual average production rate of only 65%. While the use of polysilicon project improved the production technology of Siemens method, but the integration of various enterprise systems and how efficient, modular technology is not the most advanced, reduction furnace and the design of distillation columns and other important equipment are optimized, and digestive by-products are clean, directly affect production time and reached up to yield.
It is understood, Jiangxi LDK5000 tons production line has been put into production, but is far from over production; Sichuan Tianwei Paul variable (600,550, stock it) of the two production lines of 3,000 tons, in September although production of some products, but not yet to the normal output of the project design. In addition, the Asian silicon industry, the sun silicon industry production line does not run smoothly in the short term yield is unknown.
Zhengrong Shi Suntech Chairman of the Board, President Jiang's visit to Jiangsu, said Deng Jun, the current of the polysilicon industry, the country should strengthen guidance and improve technology and reduce costs from two aspects, to build truly international competitiveness of China's polysilicon industry. If the project is completed, has not reached capacity, then the capacity is only a numbers game on paper, substantial investment will be wasted.
Excess profits, attracted by the relative excess
2008 11 months ago, the cost of polysilicon industry is a profit margin of up to 400% of the lucrative industry. The formation of such profits, on the one hand is the year 2007, thousands of metric tons of polysilicon production technology level seven companies by foreign long-term monopolies, domestic enterprises can not mass production; the other hand, in recent years to an annual global solar photovoltaic industry more than 40% rate, rapid amplification of polysilicon market demand, prices rise quickly, many companies enter the industry prospects and lower PV module industry, so that polysilicon shortage.
2008 end of the year so far, a number of polysilicon projects focused on production, including Jiangxi LDK5000 tons of production lines, Jiangsu Shunda Polysilicon Project Freshman of 1,500 tons, 1,500 tons of Jiangsu Sunshine a project, the Asian industry, a 1,000 tons of silicon production line, Jiangsu A total of 13,500 tons to total production capacity so.
In the past few years, the price of polysilicon is raspberry range: from 2002 to 20 dollars per kilogram, the end of 2007 a record 400 U.S. dollars per kilogram, the high price; 2008, the market spot prices by as much as each kg of 450 U.S. dollars.
