Polysilicon prices continued to edge lower in China this week, while wafer prices remained unchanged, reflecting ongoing weakness in the upstream solar supply chain.
The Silicon Industry Branch of the China Nonferrous Metals Industry Association (CNMIA) said on June 24 that polysilicon prices continued to edge lower. N-type refeeding polysilicon traded at CNY 31,000 to CNY 34,000/ton ($4,559 to $5,000/ton), with an average price of CNY 33,200/ton ($4,882/ton), down 0.02% from the previous week. N-type granular silicon traded at CNY 32,000 to CNY 33,000/ton ($4,706 to $4,853/ton), with an average of CNY 32,500/ton ($4,779/ton), down 0.05% week on week. On June 25, the association reported stable wafer prices. N-type G10L wafers (182 mm × 183.75 mm, 130 μm) averaged CNY 0.90/piece ($0.13/piece), while N-type G12R wafers (182 mm × 210 mm, 130 μm) averaged CNY 0.99/piece ($0.15/piece). N-type G12 wafers (210 mm × 210 mm, 130 μm) averaged CNY 1.17/piece ($0.17/piece). All prices were unchanged from the previous week.
China’s National Energy Administration (NEA) said on June 25 that the country added 8.68 GW of solar capacity in May, down 90.66% from the same month a year earlier. New installations reached 59.59 GW in the first five months of 2026, bringing cumulative installed solar capacity to 1.26 TW.
