Global polysilicon spot prices rose 3% from early August ($5.66/kg) to early October ($5.86/kg); however, prices are still below production costs for most manufacturers. In Q2 2024, the average U.S. module price ($0.31/Wdc) was down 6% q/q and down 16% y/y, and at a 190% premium over the global spot price.
That is probably the reason why the “Sun Screen” study from Credit Lyonnais Securities Asia (CLSA) quoted an average selling price of $24/kg for polysilicon in 2003. On January 1, 2004, an amendment of the German Renewable Energy Law significantly raised the feed-in tariff for electricity from solar power.
Due to the strong demand and the higher polysilicon costs, the average module price increased to $3.35/W in 2004. With a specific silicon consumption of 13 g/W and an annual spot price average of $43/kg, the share of the higher polysilicon costs ($0.56/W) in the module price ($3.35/W) rose only slightly to 16.7 % in 2004.
