Does China have direct solar radiation?

Direct normal solar radiation in China. (Note: This map was created by the National Renewable Energy Laboratory for the U.S. Department of Energy with data provided by UNEP and the Global Environment Facility.) [...] China is the world leader in several areas of clean energy, but not in Concentrating Solar Power (CSP).

What are the Interannual trends of diffuse solar irradiation in China?

Over China, the interannual trends of DSR from 1982 to 2020 are depicted in Fig. 8. Overall, the mean annual diffuse solar irradiation varied from 72.3 to 81.8 W m −2, exhibiting an overall decreasing trend of −0.012 W m −2 yr −1. More specifically, the figure delineates five periods with characteristic trends.

Can China help with the market breakthrough of concentrating solar power?

China is the world leader in several areas of clean energy, but not in Concentrating Solar Power (CSP). Our analysis provides an interesting viewpoint to China's possible role in helping with the market breakthrough of CSP. We present a short overview of the state-of-the-art of CSP including the status in China.

What is the mean diffuse solar radiation (DSR) in China?

Annual and multi-year mean DSR over China with spatial resolution of 10 km for each year during 1982–2022. The mean diffuse solar radiation experienced significant turning points in 1990, 2000 and 2010, with DSR values of 75.6 W m −2, 78.8 W m −2,79.5 W m −2 respectively. However, in 2020, there was a slight decrease in the mean DSR (78.2 W m −2).

Where is the highest CSP level in China?

The best regions are found in the western part of the country with highest daily mean values of direct normal radiation around 9 kWh/m 2 in the Qinghai-Tibet Plateau and Sichuan Basin. A minimum value of 5 kWh/m 2 ,day is the limit of CSP for economical reasons , which is met in most parts of the northern and western
