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 .
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 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.
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.
The research underscores the significant role of rooftop PV in achieving China’s energy and climate goals in its northwestern urban centers. In China, more than 75% of electricity is still generated using "dirty" coal, resulting in substantial emissions of NO x, CO 2, and SO 2 into the environment.
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.
