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 approach was applied in Shanghai, China (except for Chongming Island). The total building rooftop area of Shanghai was 253.0 km 2 and the total rooftop obstacle area was 37.7 km 2. The estimated annual rooftop solar radiation potential of Shanghai was 257,204 GWh, with a corresponding estimated annual PV power generation of 49,753 GWh.
The country's rapid development of rooftop solar capacity is also driven by government incentives. Newly added annual installed capacity for solar stations has been around 30 GW on average over the past few years, China New Energy Investment and Financing Alliance said.
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. This study assesses the rooftop PV potential in five northwestern capitals, finding favorable conditions such as ample space, dense populations, and high sunlight exposure.
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.
The assessment of rooftop solar potential is vital for optimal photovoltaic (PV) system placement and renewable energy policy in dense urban areas. Complex shading from buildings and diverse rooftop obstacles have posed significant challenges to this evaluation.
