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.

Solar panels are predominantly oriented towards the south due to several critical reasons: 1. Maximizing sunlight absorption, 2. Adapting to technological design. Enhancing energy. . Within the solar industry, it's common knowledge that the optimal orientation of solar photovoltaic (PV) panels in the Northern Hemisphere is typically south, to maximize electricity production over the life of the system. In the Northern Hemisphere, the long-standing guideline has been to position panels toward the geographic South to capture the greatest amount of sunlight. . In the United States, solar panels are typically recommended to face south.
