Polysilicon costs now account for only 20% grid tie inverter to component.

 Overall polysilicon prices declining to follow the process of PV grid tie inverter parity in 2013 is more than 20 U.S. dollars / kg in 2014 to supply 10-20 U.S. $ / kg polysilicon. "said Zhu Gong Shan judgment.

GCL's deputy general manager of Jiangsu Zhongneng Lv Jinbiao, the company has begun upgrading the existing modified Siemens process device test proved successful,grid tie inverter and in 2012 a new generation of silane fluidized bed method, completed the industrialization after each kilogram of polysilicon consumption to less than 25 kwh, a conversion rate of 98%.

Zhu Gong Shan, China Securities Journal reporter, said, "PV costs can be reduced to $ 10 / kg, short process, low power consumption,grid tie inverter the byproduct full recycling, sine wave inverter a new generation of the silane fluidized bed technology can achieve less than first-class modified Siemens Method half. "

To achieve true parity Internet,sine wave inverter not just polysilicon cost reduction, including the backplane, inverter, bracket, tracker system products include the relatively large decline in space.

Differentiated tax policies should be canceled for polysilicon

Should see the nature of the high energy consumption than the polysilicon industry,sine wave inverter but because the technical workmanship not up to standard in the industry, wind turbine inverter the early part of the project. 

"Zhu Gong Shan detained on the high energy consumption of polysilicon industry" hat "does not agree.

Before 2009, most domestic polysilicon enterprises energy consumption up to 200 kWh / kg or more, due to the tension between supply and demand in the market, the high cost of polysilicon can be sold for more than $ 300 / kg.

With the rise of China's polysilicon giant enterprises, changes in market supply, the price of polysilicon dropped to tens of dollars / kg, the high cost of polysilicon market competition eliminated.

Zhu Gong Shan, said the China Securities Journal reporter, polysilicon industry has great changes have occurred with the two or three years ago, now that the polysilicon overcapacity, which is inconsistent with the situation.

Polysilicon overall production capacity, low-cost production capacity.

 "Customs Statistics The data show that in 2012 China imported 82,000 tons of polysilicon actual polysilicon demand remains 50% dependent on imports.
