China Polysilicon Output Falls 11% in November
Production cuts by manufacturers in Xinjiang and Qinghai drove China's November polysilicon output to about 85,000 metric tons.
Updated on Nov. 2, 2026 in Energy
China's November polysilicon production declined 11.25% month-over-month to approximately 85,000 metric tons, and 25.65% year-over-year. Producers in Xinjiang and Qinghai have rolled out production cut plans, and some bases plan to switch output to anode materials.
Why it matters
Polysilicon is a core input for solar wafers, so sustained output cuts can tighten supply across the global solar manufacturing chain. Industry-wide inventory near 700,000 metric tons suggests the market has a buffer, but projected shortfalls against wafer demand indicate pressure could persist.
Monthly production data for China's polysilicon sector shows output of about 85,000 metric tons in November, down 11.25% month-over-month and 25.65% year-over-year. Industry-wide inventory has approached 700,000 metric tons, and it remains unclear whether all planned production halts will be fully carried out.
The details
Recent declines reflect coordinated production cuts among manufacturers, in addition to the usual rainy-season reductions. A base in Qinghai postponed its planned November halt to December and will remain offline until March next year, while some bases are switching granular polysilicon capacity to anode material production.
Timeline
October 2026: Significant production cuts begin across China's polysilicon sector.
November 2026: Output falls to approximately 85,000 metric tons.
December 2026: A Qinghai base postpones its shutdown to December.
March 2027: The Qinghai base is expected to remain offline until March.
Energy Transition Context
The output cuts in Xinjiang and Qinghai extend a pattern of coordinated supply restraint among Chinese polysilicon producers, following earlier industry meetings on market conditions. Their effect on global solar supply depends on whether producers continue shifting capacity toward anode materials rather than restarting polysilicon lines.
Changes in polysilicon supply can affect the cost and availability of solar panels that consumers and utilities purchase. Shortfalls against wafer demand could translate into higher module prices if inventory buffers are drawn down.
The takeaway
Watch monthly polysilicon output and inventory levels, since these figures indicate whether supply constraints will ease or tighten solar component costs. Shifts in producer strategy, such as moving capacity to anode materials, can signal longer-term changes in the sector.
