Abstract: To provide scientific basis for the reasonable planning and effective use of solar energy resources in Hunan Province, this study analyzed the spatial-temporal distribution and the richness, stability and availability of solar energy resources by employing the total solar radiation data at 3 radiation observation stations and the sunshine hours data at 97 stations in Hunan Province, and according to the solar resource assessment methods released by the China Meteorological Administration. The results showed that the solar radiation as well as sunshine hours were higher in the eastern part and lower in the western part of Hunan Province; the overall annual total solar radiation in Hunan Province tended to decrease since 1961; in Hunan Province, Dongting Lake Region and Changsha-Zhuzhou-Xiangtan Area had the most abundant solar energy resources, the largest number of days of available solar energy resources and the most stable resources, so the development and utilization of solar energy in the future should be given priority.
