China's solar industry lobby described a 66% plunge in installations during the first half of 2026 as a "return to rationalization" that puts the sector on a more sustainable footing. The sharp decline follows a government policy shift aimed at curbing overcapacity and speculative development that had fueled a boom in previous years.

The China Photovoltaic Industry Association said the downturn reflects a necessary correction after rapid, uncontrolled expansion strained grid infrastructure and created financial risks. Installations fell dramatically compared with the same period in 2025, when developers rushed to complete projects ahead of subsidy changes.

Industry officials emphasized that the slower pace allows for better integration of solar power into the grid and improves project quality. The lobby group argued that the previous growth trajectory was unsustainable and that the current reset will lead to healthier long-term development.

Analysts note the policy-driven contraction aligns with Beijing's broader push for high-quality growth over raw capacity additions. While the near-term outlook remains subdued, the association expects demand to stabilize as the market adjusts to the new regulatory environment.
