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.
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 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 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.
Rooftop installations in China increased to 27.3 gigawatts in 2021 from 19.4 GW in 2017, and the growth should keep rising for the rooftop solar market, a Rystad Energy analysis piece said. Before 2017, rooftop solar was almost non-existent, with only 4 GW of installed capacity in 2016.
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.

Photovoltaic power generation is a chemical process that converts solar energy into electrical energy, so solar irradiance directly affects photovoltaic power generation. Under the same irradiation conditions, the increase of the ambient temperature will lead to a decrease in the efficiency of photovoltaic modules, thus reducing photovoltaic power generation [ 10 ].
