Solar Silicon Price Hits Highest Level For a Decade

· Country held auction for 3.3 gigawatts of solar, wind projects

· Utilities Iberdrola, Endesa didn’t bid in Tuesday’s auction

Solar component prices, which have been rising seemingly inexorably in 2021 with a sudden spike in October, have continued their ascent. The polysilicon price reported by industry tracker PV Infolink reached $36.74 per kilogram, from $36.09/kg last week and a low of $6.30/kg in mid-2020. Wafer and cell prices are up a more modest 0.9% week-on-week, and module prices rose 1% week-on-week to 27.6 cents per Watt.
The price crunch is due to factory shutdowns in China, particularly for metal silicon, but also glass, ethyl vinyl acetate and other materials. The solar industry is rushing to build projects by year-end deadlines around the world, but there are few modules to be had for prompt delivery at any price. 
The 2021 situation is unusual in the solar industry, where prices typically fall each year. With rising prices for many commodities and logistics, it is difficult to predict where solar prices will go, but BloombergNEF expects new polysilicon factories, stability in China, and improving technology to bring prices down in 2022.
