In our country, the western region of Tibet's most resource-rich solar energy, up to 2333 KWh / m 2 (day radiation 6.4KWh / ㎡), ranking second in the world, second only to the Sahara desert.

According to the accepted throughout the global solar radiation of how much the country can be divided into five regions.
A class of the region
China's solar energy resources as the richest region, the total solar radiation in 6680 ~ 8400 MJ / ㎡, which is equivalent to the amount of radiation on 5.1 ~ 6.4KWh / ㎡. These areas include the northern part of Ningxia, and Gansu in the north, the eastern part of Xinjiang, Qinghai and the western region of the western region of Tibet and other places. Especially in the western region of Tibet are the richest of up to 2333 KWh / m 2 (day radiation 6.4KWh / ㎡), ranking second in the world, second only to the Sahara desert.
II region
China's solar energy resources for the rich region, the total amount of solar radiation in 5850-6680 MJ/m2, equivalent to the amount of radiation on 4.5 ~ 5.1KWh / ㎡. These areas include the north-west of Hebei, Shanxi in the north and south of Inner Mongolia, Ningxia Hui Autonomous Region in the south, in central Gansu, Qinghai, eastern and south-eastern Tibet and other places in southern Xinjiang.
Three types of areas
China's solar energy resources for middle-type area, the total amount of solar radiation in 5000-5850 MJ/m2, equivalent to the amount of radiation on 3.8 ~ 4.5KWh / ㎡. Including Shandong, Henan, Hebei, southeastern, southern Shanxi, the northern part of Xinjiang, Jilin, Liaoning, Yunnan, Shaanxi in the north, the south-eastern Gansu, southern Guangdong, southern Fujian, Jiangsu, northern Anhui, south-west of Taiwan and other places.
Four areas
China's solar energy resources in poor areas, the total amount of solar radiation in 4200 ~ 5000 MJ / ㎡, which is equivalent to the amount of radiation on 3.2 ~ 3.8KWh / ㎡. These areas include Hunan, Hubei, Guangxi, Jiangxi, Zhejiang and the northern part of Fujian, Guangdong, the northern, southern Shaanxi, the northern part of Jiangsu, Anhui, Heilongjiang, as well as in the south, north-east of Taiwan and other places.
Five areas
Including Sichuan, Guizhou provinces, China's solar energy resources in the area at least, the total amount of solar radiation in 3350 ~ 4200 MJ / ㎡, which is equivalent to the amount of radiation on only 2.5 ~ 3.2KWh / ㎡.
Solar radiation data from meteorological stations at the county level achieved can also be obtained from the National Weather Service. From the Bureau of Meteorology data is the level of radiation data, including: the total level of radiation, the radiation level of direct and scatter radiation level.
