In 2021, China’s newly installed capacity of distributed PV is 29.27 GWp, accounting for 55% of the total installed capacity. It has entered a rapid development stage (Li and Huang, 2020, Anon, 2022a). There are 676 rooftop solar photovoltaic (RTSPV) pilot projects in 31 provinces in China in 2021 (Anon, 2021a).
The variability was extremely high (CV > 0.6) in the Sichuan basin and the middle and lower reaches of the Yangtze River, due to frequently cloudy and rainy weather. The spatial pattern of CV implied that most rooftop PV generations were characterized by significant volatility and uncertainty.
A novel systematic method for assessing the potential of urban rooftop PV is proposed. Residential areas contribute 50% of the total rooftop PV potential in Guangzhou, China. The rooftop PV potential in Guangzhou reaches 44.06–72.12 billion kWh per year. Rooftop PV reduces carbon emissions in the power sector in Guangzhou by 72.12–100%.

Our results showed that the total rooftop PV potential in China reached 6.5 PWh yr −1, mainly concentrated in the eastern region where PV generation showed high variability. The carbon reduction from 100% flexible grids with 12 h of storage capacity is close to the theoretical maximum, while without storage, the potential may be halved.
