Chinese PV Industry Brief: More inverter, battery and solar cell capacity


Polysilicon manufacturer GCL-Poly today reported its RMB700 million (US$107 million), 10,000 metric ton (MT)-per-year production line for fluidized bed reactor-based granular silicon is using 30% less hydrogen than the previous, 6,000 MT line, and has also reduced the metal and carbon content of the polysilicon, as well as diminishing the fine powder rate. Requiring a maximum 20 kWh of electricity per kilogram produced, the company said it expects further hydrogen content reductions in its next, 30,000 MT production line.

Battery company CATL and inverter maker Kstar today announced completion of construction of the 1 GW-annual-production-capacity fab established by the partners in Xiapu economic development zone, in Fujian. The 206,907m2 facility features two inverter production lines, two “charging lines” and a battery pack assembly unit. 

Polysilicon manufacturer Xinte Energy on Friday announced shareholders will vote, on March 25, on plans to build a 100,000-ton-per-year-production-capacity factory in Baotou City, Inner Mongolia. The facility was described as a “circular economy construction project” but Xinte did not release any details about its circular economy features.
