PVinsights: Liquidity Crisis Forces Top Wafer Makers Propping Up Prices

Alternative Energy - Thu, 05/25/2017 - 08:55
Tepid procurement momentum continues to hold polysilicon prices steady this week amid mounting concerns of demand outlook after June 30th. Although some Chinese polysilicon suppliers attempt to raise prices along with the price hike of multi-crystalline wafers, most buyers are reluctant to accept as they realized the possible risk of price decline in near future. Moreover, as many buyers have already secured inventories, they do not have immediate need to purchase at this moment. Instead, they have buffer time to take conservative approach and wait for demand clarity. Hence, the latest attempts for Chinese polysilicon suppliers to strengthen the prices had only limited success.
