At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect. ". The Chinese solar industry is at a pivotal point. 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. So there is a lot of uncertainty in the. . Wind and solar surpassed a quarter of China's electricity generation for the first time in April 2025. Its PV capacity crossed 1,000 gigawatts (one terawatt, 1 TW) in May 2025. [1]. . China has invested over USD 50 billion in new PV supply capacity – ten times more than Europe − and created more than 300 000 manufacturing jobs across the solar PV value chain since 2011. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
