China’s solar market heads for first annual contraction since 2019

China's solar industry is pulling back this year, with factory output and new installations both dropping after 2025's unusually high numbers. Manufacturing fell across the board: polysilicon (the raw material for solar cells) production dropped nearly 10%, and finished solar panel output fell 35%. Prices for raw materials also dropped sharply, though panel prices ticked up slightly.

New solar installations in China fell about 66% compared to the same period last year, but that comparison is misleading. Last year saw a rush to connect projects before China changed how it prices renewable energy in June 2025, so 2025's numbers were inflated. Industry group CPIA says this year's installation pace, while lower, is actually more sustainable and still above the average from 2021-2024. Full-year 2026 installations are still expected to mark China's first annual decline since 2019.

For homeowners, this is mostly background news about the global supply chain rather than something with immediate local effects. China remains the dominant source of solar panels worldwide, and its exports of panels and cells actually rose this year even as domestic installation slowed. Industry forecasters expect the global solar market to shrink slightly in 2026 before resuming growth in 2027. None of this changes rebates or incentives for installing solar at home, but shifts in panel pricing and supply from China can eventually filter through to what panels cost here.
