Trolley car conundrum

The U.S. solar industry faces a moral dilemma, writes Paula Mints of SPV Market Research. Either continue to deploy projects and set aside concerns about forced labor in China’s Xinjiang region, or source PV cells and modules from elsewhere, while bearing higher costs, in the pursuit of urgent action against climate change.

Polysilicon amid international trade disputes

Polysilicon capacity is unable to catch up with rapid capacity expansion in the mid and downstream segments, writes Corrine Lin, chief analyst for PV InfoLink. New polysilicon capacity requires big capex investment and a lead time of more than two years to complete construction and reach full operation. With unbalanced capacity between the upstream and downstream segments, polysilicon prices have been rising since the second half of 2020, with prices for mono-grade polysilicon surpassing CNY 200/kg ($27.40) in June 2021, up more than 250% year on year.

Global tracker shipments reached 45 GW in 2020

The global single-axis tracker market increased shipment volume by 40% year on year to reach 45 GW in 2020. This was despite significant pandemic-related supply chain turbulence that resulted in longer lead times for the delivery of components, the idling of steelmaking capacity in some key markets, container shipping dislocation, and widespread restrictions, particularly at ports. Most notably, this caused the cost of some commodities, such as steel, to more than double between 2020 and 2021. Jason Sheridan, a senior research analyst for IHS Markit, runs through some of the key developments in the tracker market.
