After closing a supply contract with South Korean polysilicon maker OCI in early February, leading Chinese monocrystalline wafer, cell and module manufacturer Longi Green Energy Technology has signed another contract for the delivery of high-purity polysilicon, namely with Chinese polysilicon producer Daqo New Energy.

While the contract with OCI comprises the delivery of 64,638 metric tons (MT) from OCI's Malaysian subsidiary over three years from March 2018 through February 2021, the agreement with Daqo entails shipments of 39,600 MT from April 2018 through December 2020. Daqo will receive an upfront prepayment.

Longi has also secured a 15% stake in Sichuan Yongxiang New Energy Technology Co., Ltd., a subsidiary of Tongwei Group, which is building a 25,000 MT polysilicon plant in Leshan, Sichuan province, slated to come on stream by the end of 2018.

Longi is planning to triple its wafer production capacity from 15 GW at the end of 2017 to 45 GW by the end of 2020.
