Estimation of the solar radiation potential in an area is one of the most basic foundations in the development of research for applying solar energy in any region. In this study, the necessary information was taken from 9 out of 21 solar radiation stations in the country within a period of 5 to 11 years. After refining the information for some incorrect lays, then it was used for intended model or mode.In order to estimate the daily average of monthly radiation on the horizon level, the existing models were closely studies and among them, 3 mathematical models, namely “angstrom pries cut”, “the most probable model” , and “Hybrid model” were used.The related coefficients of each model for Iran were calculated through statistical relationship by using processed data from the above mentioned stations.These mathematical models were statistically tested for Iran and from these three, the hybrids model was chosen as the best alternative. The final result of this research is 12 drawings concerning the daily solar radiation in each month, 4 drawings related to the total radiation received by the horizontal area for each season, and one drawing in relation to the total radiation received by the horizontal area during a year.
