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).
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.
There are only 103 solar radiation observation stations until 2008 in Chinese mainland . Long-term data on global solar radiation are not available for most areas in China, especially in remote rural and mountainous areas, where approximately 80% of the Chinese population is living .
Thus, understanding the long-term variations of solar radiation is important for planning the utilizations of solar energy resources over mainland China in the future. Measurement by pyranometer with accurately calibrated are the best way to obtain the long-term SSR data (Wang et al., 2012).
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).
