The world's main energy source is the sun. Other energy sources are caused directly or indirectly from the sun. Turkey has a rich potential in terms of solar energy and interest in solar power systems is increasing in the rapidly evolving technology. In all of the solar energy studies needs solar radiation data but solar radiation measurements are not possible on each area. Therefore, estimation of the solar radiation by using a variety of methods are emerging importance. In this study, Turkey and Adiyaman solar energy potential is investigated and statistical analysis was performed for Adiyaman. Various parameters were estimated by using actual solar radiation data from the Meteorology and experimental data were compared with theoretical ones. According to the results of the statistical analyzes, Adiyaman data indicate the best fit with the cubic model.
