China’s mainstream TOPCon 210R solar-module prices resumed their decline from September through mid-October after a brief August rebound.
The August recovery followed a period in which some manufacturers held prices firm and buyers placed concentrated orders in stages. That support faded in September as demand failed to absorb available supply. Finished-module inventories declined only modestly during the month and remained well above historical lows, leaving stock at both manufacturers and distribution channels capable of returning to the market when purchasing weakened.
Production has also recovered from a temporary pullback in the spring and continued at a high level for the year. Output remains below the same period a year earlier, but monthly changes have been limited and absolute supply remains ample. The combination of substantial production and incomplete inventory clearance has kept the market from tightening enough to support a sustained price increase.
Low-efficiency modules are adding another source of price pressure. As energy-efficiency standards become clearer, holders of products that may struggle to meet future requirements are seeking to sell before those products become harder to place through mainstream channels. Discounts, promotions and margin concessions bring lower-priced supply into customer segments that overlap with conventional TOPCon modules, giving buyers greater leverage and pulling down the broader transaction level.
Upstream market signals point to the same uneven balance.
Module prices are now close to the cash-cost lines of many producers, which limits room for further declines and gives high-cost capacity an incentive to reduce losses. That cost floor has not created a rebound: buyers remain focused on lower prices, and concentrated procurement has been intermittent rather than sustained. The balance of high production, replenishing inventories and limited demand absorption therefore points to low-range trading in the fourth quarter, with stabilization possible if centralized project deliveries accelerate enough to clear stock, but no confirmed basis yet for a lasting reversal.
