Due to the implementation of the "double carbon" strategy, renewable energy has received widespread attention and rapid development. As an important part of renewable energy, solar
The difference in electricity generation over the whole of China, comparing the baseline and dimmed radiation levels, and with 2016 installed PV capacities, are estimated at 14 TWh yr −1, or...
This integration of radiative cooling and PV power generation signals a transformative shift toward optimizing energy conservation without sacrificing the benefits of solar energy. Through comprehensive numerical
Long-term solar radiation datasets were reconstructed across China. Global solar radiation in summer decreased by up to 1.83 W·m −2 ·decade −1. China’s PV power potential decreased by 1.69 kWh·m −2 ·decade −1 from 1961 to 2016. 30 provinces saw a 0.25–10.27% reduction in PV potential in the 2010s versus the 1960s.
Western China is an optimal location for solar photovoltaic power plants. Global solar radiation (Rs) is a key parameter for determining the energy yields of solar photovoltaic (PV) systems. However, long-term Rs data are not available in most regions of China, impeding the management and development of PV systems.

China’s PV sector showed a regional mismatch between PV potential and installed capacity.
Having surpassed the 2020 PV development target of 110 GW, China is well on track to realize its goal of reaching 400 GW of installed PV capacity by 2030, to meet its commitment to the Paris Agreement of obtaining 20% of primary energy from renewable energy sources 6.
In China, there are substantial regional variations in solar power generation potential affected by shortwave radiation, land availability and installation densities, showing a downward trend from northwest to southeast [ 35, 36 ].
The newly developed empirical model can accurately estimate global solar radiation. The annual photovoltaic power exhibited a significantly declining trend. Western China is an optimal location for solar photovoltaic power plants. Global solar radiation (Rs) is a key parameter for determining the energy yields of solar photovoltaic (PV) systems.
