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.
However, our conclusions have policy implications for the large-scale consumption of PV power generation in China and other countries. In 2014, China's PV cumulative installed capacity reached 28.05 GW. Currently, supportive policies in China focus on the national level.
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 .
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.
