However, the configuration of energy storage for household PV can significantly improve the self-consumption of PV, mitigate the impact of distributed PV grid connection on the distribution network, ensure the safe, reliable and economic operation of the power system, and have good environmental and social benefits.
Solar PV of China accounted for about one third (174GW) of the global total installed capacity in 2018 and contributed to 3.5% of national total power generation in 2020 .
China’s rural residential photovoltaic system has been greatly developed in recent years. However, most existing researches, are difficult to reflect the real development situation of the whole system.
As shown in , since 2013, China’s newly added distributed photovoltaic installed capacity have fluctuated upward, and reached 29.28 GW by 2021, accounting for 53.4% of the total, and exceeding the centralized photovoltaic system for the first time in history.
With regard to technology research and development, the latest photoelectric conversion efficiency of China’s mass production of silicon solar cell has reached more than 25%, which is the world’s leading level (Chen et al. 2022).

Long-term development of solar PV in China 4.1.1. National development pathway As shown in the long-term simulation made by different models (Fig. 3), amount of solar power generation in 2050 ranges from 3200 to 6300 TWh (billion KWh).
