In 2050, the cost of off-grid PV power generation will decrease to 0.596–0.929 RMB Yuan/kWh. Xigaze, with the best solar radiation, will first reach the grid parity between 2026 and 2030. And Chongqing will be the last one to reach the grid parity because of its poor solar radiation (between 2037 and 2050).

Photovoltaics. Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels.
