Proving the distribution and changes of solar energy in China is a necessary foundation for the stable development of the PV industry (Kazaz and Adiguzel Istil 2019). Since the 1950s, the surface solar radiation has been on a downward trend, and this trend continued until the 1980s (global dimming) (Stanhill 2005).
Some parts of the country get 2 MWh/m 2 solar irradiation and 3,000 h of sunshine per year, which is ideal for setting up solar energy parks to exploit the true potential of solar sources in the country (Kamran et al. 2019). Several scholars have analyzed the growth of solar energy in the Chinese context from various angles.
As can be seen, the ensemble mean captured the seasonal distribution of solar radiation well over China, with the largest values (180–320 W m −2) in JJA and smallest values (60–200 W m −2) in DJF.
The results of both studies indicate that insolation is highest on the Tibetan Plateau and lowest in the Sichuan Basin, and suggest that the receipt of solar radiation in China is impacted by both seasonal and interannual variations.
Figures 9 a and 9 b show that the annual average DGSR ranges from 6 to 26 MJ/m 2, with a national-average value of 15.55 MJ/m 2 during 2013–2014. Spatial differences are evident across China, indicating that the solar radiation intensity in northern China (western China) is higher than that in southern China (eastern China).
Several scholars have analyzed the growth of solar energy in the Chinese context from various angles. Irfan et al. (2019a, b) emphasized the significance of solar energy for power production in China and evaluated the potential of electricity generation from solar sources.
