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.
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).
Most of the country's distributed solar photovoltaics are installed in the eastern and southern parts of China, where the economy is prosperous and demand for power is greater, including in Zhejiang, Shandong, Jiangsu and Anhui provinces.
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.
The accumulated installed capacity of distributed solar PV now accounts for 27.1 percent of China’s total solar PV installation. Distributed solar PV has been installed mainly in east and south China, where the country’s economy is most prosperous and demand for power is greatest.
2030 is a critical milestone for China in achieving carbon peak, and large-scale deployment of rooftop photovoltaics is one of the key measures to support this goal in response to national planning and design. Hence, this study selects the summer of 2030 as the simulated period .
