Most of that rooftop solar has been added in the past two years, as China offered support for local governments to boost installations, and raised power rates to businesses, making generating their own electricity more attractive.
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.
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 buildings and rooftops have the potential to host more than 1 terawatt of solar power capacity, almost the same size as the entire existing global industry, according to the manufacturer.
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.
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 .
