Spot prices for polysilicon, the raw material used in most solar panels, posted its biggest weekly drop since June, signaling the industry’s slump may be deepening.
The average selling price dropped 5.8 percent to $43.78 a kilogram on Oct. 10 from a week earlier, according to London-based Bloomberg New Energy Finance’s survey of contracts conducted from Oct. 3. Multicrystalline solar cells, which are assembled onto panels, slid 4.1 percent to 70 U.S. cents a watt.
