China installed a record 315 GW (AC) of new solar capacity in 2025, lifting cumulative installed PV capacity to 1. 2 TW and pushing non-fossil power sources past thermal generation for the first time. China's National Energy Administration (NEA) released its 2025 power sector statistics on Jan. 28. . Last year, a viral drone video from China's Guizhou province revealed an entire mountain range blanketed in solar panels stretching to the horizon. Rapid solar capacity expansion overwhelms the grid, PV manufacturers compete for market shares, and then large target markets slap import tariffs on Chinese PV products, taking off their competitive edge. It is published annually as a March special issue of the China Energy Policy Newsletter.
