In a further sign of the continue supply-demand imbalance in the solar sector, weekly data from Bloomberg New Energy Finance suggests that the spot price of polysilicon, the raw material used in most solar panels, accelerated to the downside last week, falling at the fastest pace since June. Prices of solar wafers and cells also continued their decline:
‘The average selling price dropped 5.8 percent on the week to Oct. 10 to $43.78 per kilogram, according to the latest results from the London-based research firm’s survey of contracts conducted from Oct. 3 to Oct. 10. The price of six- inch solar wafers dropped 3.3 percent to $1.74 each and multicrystalline photovoltaic cells slid 4.1 percent to 70 U.S. cents per watt of capacity’.
- continued oversupply in the sector, as evidenced by the new data from BNEF
