Two kinds of areas
Our country is rich in solar energy resources area,Gaosuibuyou Thailandsolar panels annual total solar radiation for 5850-6680 MJ / m2, equivalent to a daily radiation from 4.5 to 5.1KWh / square meters. These include areas of Northwestern Hebei, northern Shanxi, southern Inner Mongolia, southern Ningxia, central Gansu, Eastern Qinghai, southeastern Tibet and southern Xinjiang.
Three kinds of areas
China's solar energy resource medium type area, annual total solar radiation for 5000-5850 MJ / m2, equivalent to a daily radiation from 3.8 to 4.5KWh / square meters. Including Shandong, Henan, southeastern Hebei, southern Shanxi, northern Xinjiang, Jilin, Liaoning, Yunnan, northern Shaanxi, southeastern Gansu, southern Guangdong, southern Fujian, North Jiangsu, Anhui, southwestern Taiwan.
Four kinds of areas
China's solar resource poor regions,solar modules annual total solar radiation of 4200 ~ 5000 MJ / square meters, equivalent to a daily radiation from 3.2 to 3.8KWh / square meters. These areas include Hunan, Hubei, Guangxi, Jiangxi, Zhejiang, northern Fujian, northern Guangdong, southern Shaanxi, northern Jiangsu, southern Anhui and Heilongjiang, northeast Taiwan and other places.
Five kinds of areas
Mainly includes the Sichuan, Guizhou province two, is China's solar energy resource is the fewest area, annual total solar radiation of 3350 ~ 4200 MJ / square meters, equivalent to a daily radiation only 2.5 ~ 3.2KWh / square meters.
Solar radiation data can be obtained from the meteorological stations at the county level, can also be obtained from the National Meteorological bureau. The data obtained from the Bureau of meteorology is the water level of radiation data, including: horizontal total radiation, horizontal direct radiation and scattering radiation level.
From the point of the whole nation,toner China is very rich solar energy resources of the country, most areas of radiation annual average daily volume in 4 kWh / square meters above, Tibet up to 7 kWh / square meters.
