Solar energy (Solar energy) is high potential renewable energy. Without pollution does not cause deterioration of nature. Animals and the environment, including the human body. Heat production and hence the informatics systems used in the analysis of finding suitable space for the solar power plant is located, with the criterion used is the Landsat 5 TM satellite photo in the years 2006 and 2009 2011. Surface temperature, heat The Suns intensity of land utilization direction of light weight, brought up by the process of hierarchical analysis. (Analytic Hierarchy Process :AHP) from experts and data overlay (Overlay) by results of an analytical study of the suitable area has 5 levels, is the area that is most appropriate for an area of 2805.2 sq. km. Areas that are most appropriate to an area of 4140.76 square meters.Km, the area is sompanok sq. km. space 1900.1 lang. Areas that are less appropriate to an area of 1030.83 sq. km. Areas where there is no appropriate space 358.23 sq. km
. The result in an analysis of the proper set up solar power plants in the province. To bring data that is used to decide which potential areas for solar power plants properly
.Key words: surface temperature of the solar/heat/Suns intensity/direction/exposure process of hierarchical analysis. (Analytic Hierarchy Process :AHP)
