Although the rapid rise of the thin film battery, but the crystalline silicon solar cells is still the main force of the solar cell industry. In 2007 the world’s top 10 solar cell business, there are 9 production of crystalline silicon-based solar cells. China’s Suntech (Suntech), Hidetoshi (Yingli), JA (JA Solar), respectively ranked the first place 2,9,10.
Solar cell industry expansion is reflected in two aspects, on the one hand Inspiron 9400 battery, for the expansion of existing manufacturers, on the other hand, for new entrants to the industry. In 2007, the global battery production capacity is about 6.4GW, production was about 3.4GW; one of the top 10 largest battery capacity providers together about 3.1GW, the world’s production capacity of about 48% of the total output accounts for about 66%.
If the top 10 solar cell manufacturers of similar plans for expansion throughout the solar cell industry’s expansion plans, we come from similar to the 2008-2010 global solar cell supply growth was 80.7 percent, 43.6 percent, 46.2 %.
Relative from the 2008-2010 global solar energy demand growth, we judge in 2009 will be slightly over-supply of solar energy industry of the year, hp battery in this scenario, the solar cell manufacturers to the lower reaches of the premium for the ability, to reduce costs by The profits will be room for most of the demand to link.
In accordance with our polysilicon prices in 2009 and 2010 the average price is expected to drop to 200 dollars and 120 U.S. dollars to the estimated end-product prices decreased. Nanjing sample CLP (cell-chip manufacturers, silicon from the spot market purchases), the market price of polysilicon 300 U.S. dollars / kg, the cost of silicon cells accounted for 91.2 percent of the cost to 2.79 U.S. dollars / kw, the battery-chip prices For 3.37 U.S. dollars / kw, and then consider the cost of silicon wafers account for about 75% of the price, estimated polysilicon film battery terminals account for 62% of the price. We have to judge, polysilicon prices brought about by the transfer of profits most of the lower digestive expected over the next 2 years, battery-chip prices drop about 15%. In extreme cases, over the next 2 years, the annual price declines of up to 20%
