PVinsights: As mono wafer prices drop, upstream rally hit the brakes

Alternative Energy - Fri, 06/16/2017 - 08:39
Polysilicon prices had a moderate decline this week. As polysilicon buyers have already prepared enough inventories for the installation raft in June, they had no immediate rush for procurement at this moment. Instead, they tend to take a defensive stance as they anticipated a price downturn in the near future. Suppliers have started to slightly lower the prices amid dimmer outlook in late June. Overseas market remained bearish due to limited utilization rates of downstream wafer suppliers. With low utilization rates, wafer producers did not show interest in further purchase and hesitate to procure considering current prices were too high.
