IEA reports over 90% of Chinese solar manufacturers posting net losses

The International Energy Agency reports that more than 90% of major Chinese solar PV manufacturers posted net losses in 2024. According to the IEA, these firms, along with major polysilicon producers, accumulated a combined net loss of $4.4 billion last year.

Solar module prices have risen between 10% and 30% compared to 2025 levels.

Financial Performance

The International Energy Agency indicates that net margins for Chinese solar manufacturers remained negative through the first three quarters of 2026. The agency’s data shows that the middle 50% of these companies reported net margins between -5% and -15% in recent quarters. This represents a shift from 2024, when the same middle half of the industry recorded net margins ranging from 0% to -30%.

Industry Consolidation

• Over 70 companies filed for bankruptcy or liquidation since 2024, according to the IEA.
• Solar companies are shifting toward battery storage to access higher margins, per the IEA.

Capacity Projections

The IEA projects significant contractions across the solar supply chain by 2031, with the magnitude of reduction dependent on market conditions. Polysilicon capacity faces the steepest potential cuts, while downstream segments like wafer, cell, and module production are forecast to see more moderate declines.

Supply Chain Segment	Projected Capacity Change by 2031 (IEA)
Polysilicon (Base Case)	-45%
Polysilicon (Improved Conditions)	-15%
Wafer	-10% to -35%
Solar Cell and Module	-5% to -15%

Market Structure

The International Energy Agency projects that global solar supply chains will remain highly concentrated in China through 2031. This structural dominance persists despite the financial distress affecting domestic manufacturers, as the IEA notes that non-Chinese firms have maintained median net margins between 10% and 15% since 2023. While China retains the bulk of production capacity, the agency identifies emerging manufacturing hubs elsewhere that are focusing specifically on cell and module production.

Supply Chain Specifics and Market Context

According to the IEA’s Renewables 2026 report, Chinese manufacturers are seeing margin improvements primarily in those diversifying into higher-value areas such as energy storage system integration. The agency cautions that if expansion outpaces demand, this trend "risks transferring the solar industry’s overcapacity dynamics into the battery supply chain." Upstream sectors are undergoing the most substantial adjustments, as they hold the bulk of China’s excess manufacturing capacity. Beyond China, the IEA highlights India as a significant emerging hub, where new capacity is centered on cells and modules due to their lower upfront capital requirements compared to polysilicon and wafer production. The report notes that trade barriers and industrial policies are increasingly dictating where new capacity is located, emphasizing that new entrants require distinct competitive edges, such as technological differentiation or policy backing, to thrive in today’s low-price landscape.

Current market data offers further insight into these structural changes. Luminity reported on November 11, 2026, that FOB China mainstream TOPCon 645 Wp module prices were $0.107/Wp in October, representing a 0.93% drop from September. Conversely, upstream costs have surged; since early August 2026, FOB China n-type M10 wafer prices jumped 23.14%, while n-type M10 cell prices climbed 18.41%. In August 2026, China installed 11.04 GW of solar capacity, marking a 21.6% month-on-month decrease. As of that date, no timeline has been established for resolving legal disputes regarding long-term supply contracts.
