Grid-connected PV Systems Development in China In order to help balance the mismatching of solar radiation distribution in the west and load centre of power grid in the east, grid-connected PV system has been developed rapidly in China. 3.1. Distribution of solar resource in china China is rich in solar resources compared to the world average.
According to the characteristics of power grid and solar energy distribution in China, it is believed that high efficiency and market-competitive grid-connected technology is critical.

As a result, traditional producers and PV power generation may move towards a fair competitive environment, which is more conducive to grid parity of PV power generation. In addition, China's carbon trading is fully implemented in 2017, covering eight sectors including power sector.
Most of China's solar power is generated within its western provinces and is transferred to other regions of the country. In 2011, China owned the largest solar power plant in the world at the time, the Huanghe Hydropower Golmud Solar Park, which had a photovoltaic capacity of 200 MW.
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.
The government incentives have also contributed to the curtailment of solar energy, as many of the solar projects have been built in northern and western regions of China where there is a low demand for electricity and a lack of infrastructure to transfer energy towards China's main power grid.
