The annual mean global solar radiation in China from 1961 to 2016 was estimated at 174.36 W·m −2, with a decreasing trend of −0.83 W·m −2 ·decade −1.
The average yearly potential for solar power generation in China from 1961 to 2016, assessed with global horizontal radiation data from the PSO-XGBoost model, reached 285.00 kWh·m−2.
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.
Previous studies usually used limited observation data for modeling and analyzing global solar radiation in China , , that has a land area of ~9.6 million km 2. These limited data potentially result in partial valid conclusions owing to their inadequate representativeness.
