The basic components of these two configurations

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).
A high-resolution solar photovoltaic potential map of China utilizes the open dataset and one novel neural network model. The data are stated by provinces and cities showing the regional differences. The rooftop photovoltaic generation will be closed to half of the electricity generation of China mainland in 2020.
Yu Wang et al. use the data of urban development land area to conclude that the total installed capacity of distributed photovoltaic in China can reach 380 GWp–1150 GWp under different development intensities (Wang et al., 2021). Moreover, a “Top-down” method can be used to calculate the building area.
Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
