The eastern region has great accumulated photovoltaic electricity potential, which is 3.21 times that of the western region. Rooftop photovoltaic system plays an important role in solar energy power generation especially in urban. In this paper, we present an assessment method for the PV power generation potential of rooftop in China.
Rooftop solar PV installations in China may surge in the next three years as the country goes through a green energy transition and plans to make renewable energy a key cornerstone in the country's path to a greener economy, a recent research report said.
This has become a significant strategic goal for China's future energy ( Huang and Wang, 2018 ). Photovoltaic (PV) power generation is an important form of solar energy use. Different policies have encouraged its development, including those addressing technology development, production, and application.
In this paper, we present an assessment method for the PV power generation potential of rooftop in China. Using machine learning model processes the big data that consists of the gross domestic product, building footprint, road length and population, at a high geographic resolution of 10 km by 10 km.
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.
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).
