The 275,000 metric tons of annual polysilicon production facilities pushed out of the industry by the expansion of big Chinese producers is more than double the capacity lost in the last great poly market shake-out, between 2010 and 2013.
Longi Green Energy Technology Co., Ltd has announced plans to build a 228 MW solar PV project in China. The Chinese vertically integrated solar PV manufacturer has also signed a 39,600 metric ton (MT) high purity polysilicon agreement with Daqo New Energy Corp.
Polysilicon and wafer manufacturer ranking: PV demand reached record levels in 2017, with global installations surpassing 100 GW for the first time ever. Few in the industry expected deployments to hit this level, piling the pressure on to the supply chain. Armed with polysilicon and wafer manufacturer ranking data supplied by IHS Markit, pv magazine delves into the past year’s upstream landscape.
The use of diamond wire significantly reduces wafer saw losses. Some photovoltaic manufacturers have begun to switch their production, after technical problems appear to have been resolved.
