China TOPCon solar cell prices fall for third week as export buying fades and wafer costs ease

Prices for solar cells made in China have dropped for three weeks in a row, as a rush of overseas buying tapers off and the cost of raw materials like silicon wafers and silver eases. Two common cell types tracked in industry pricing reports, TOPCon M10 and 210R, are now about 12% below their late-August highs, though still well above where they stood in early August.

The earlier price spike was driven partly by buyers stocking up before new U.S. tariff measures (Section 232) take effect on Dec. 4. That rush has slowed as overseas warehouses fill up. At the same time, demand inside China has softened because a shift to market-based electricity pricing has made new solar projects less profitable than under the old fixed-rate system. China's cell production ticked up slightly in August but remains well below year-ago levels.

For homeowners, this is mostly background noise for now: cell and wafer prices are one layer in the supply chain that eventually feeds into what solar panels cost, but there's no direct rebate, deadline, or program change here that affects your own home. The bigger price mover on the horizon is the U.S. tariff measure taking effect in December, which could push solar equipment costs up rather than down. Industry watchers are also eyeing a possible production-cut agreement among Chinese polysilicon makers, which, if confirmed, could tighten supply and firm up prices further into the fall.
