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.
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 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.
China’s pursuit of photovoltaic (PV) power, particularly rooftop installations, addresses energy and ecological challenges, aiming to reduce basic energy consumption by 50% by 2030. The northwest region, with its solar potential, is a focal point for distributed PV growth, which has already exceeded 50% of the energy mix by 2021.
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). Rooftop solar photovoltaics use building roof resources to design distributed photovoltaic power stations (Tripathy et al., 2016).
The research results of this paper can roughly provide suggestions for the rooftop distributed photovoltaic development strategy in China, and help decision makers analyze photovoltaic potential and CO2mitigation ability. Funding
