Polysilicon prices have plateaued since early June, when they reached an average spot price of RMB206/kg (US$31.7/kg), and did show early signs of falling in late July. But they have since risen and plateaued again, staying stagnant at around RMB203/kg.

Earlier this week Longgen Zhang, chief executive at polysilicon producer Daqo New Energy, noted how in the opening weeks of Q3 2021 average selling prices for polysilicon had risen to US$26 – 28/kg, up from the Q2 average of ~US$20/kg with demand for modules – and in turn cells and wafers – remaining strong despite higher prices.

Daqo also noted that recent policy initiatives in China have intended to stimulate deployment of distributed solar projects across the country, which is also increasing the demand forecasts for solar modules from September onwards.

As a result, polysilicon supply is expected to remain tight throughout the rest of the year.
