The plant will be built in Quanzhou in China’s southeastern Fujian province, across the sea from Taiwan.

The investment will allow GCL-Poly to tap the Taiwanese market and other “strategically important” emerging markets in Southeast Asia, says the firm’s president Shu Hua.

Hong Kong-based GCL-Poly is China’s largest producer of polysilicon, the raw material used in PV solar cells.

It has embarked on an ambitious expansion programme, ramping up its wafer production and also moving further downstream with the operation of a 20MW solar farm in Jiangsu province and projects in the US.

Goldpoly, which also operates a retail clothing business, has an annual capacity of 200MW.
