According to the solar resource assessment methods released by China Meteorological Administration, many years of the total solar radiation data about Changsha meteorological station, the direct radiation data about Wuhan station and the sunshine hours data about Anxiang station, this study analyzed the distribution and the richness, stability and availability of solar energy resources in Anxiang County of Hunan Province since 1962 to 2015. The results showed that, the overall annual total

The quantity of radiation is the most in summer, the second in spring and autumn, and the least in winter. The assessment of solar energy resources in this region shows that Anxiang County is a rich area of solar energy resources, and solar energy resources are more stable. The average available days of solar energy resources are 166.3 days in this region.
