Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations. The basic components of these two configurations

With its total installed capacity of solar PV surpassing that of the United States in 2013 and Germany in 2015 (15, 16), China has maintained its leading global position in terms of not only the deployment of solar power but also the manufacture of PV modules.
With addition of 48.2 GW in 2020, China’s installed capacity of solar PV rose to 253.4 GW (12), far ahead of a target of 105 GW set for 2020 in the 13th 5-y plan (17). The large-scale installation of solar power both globally and in China has promoted improvements in PV conversion efficiencies and reductions in generation costs.

China's electricity market is facing a series of reforms, which may further promote grid parity of PV power generation. The residential electricity price in China is controlled by the government based on cost-plus principle. The electricity price cannot reflect scale of product/service and market supply and demand .
In 2014, China's PV cumulative installed capacity reached 28.05 GW. Currently, supportive policies in China focus on the national level. Few of these policies consider regional difference, such as the distribution of solar radiation and economic development.
