In this research, the monthly mean daily global solar radiation in Kerman was predicted, using geographical, geometrical, astronomical and meteorological parameters. The measured data of global solar radiation, obtained from the Iranian Meteorological Organization (IMO), were used and the predicted results were compared against them. The analysis of measured data
showed that the monthly mean daily global solar radiation on a horizontal surface is correlated with seven geographical and meteorological variables. The above variables were incorporated in a multiple regression relation predicting monthly mean daily global solar radiation on a horizontal surface. The global solar radiation model developed in this research, whose accuracy
was validated when compared to measured data, can be used in regions where meteorological stations are not available and, therefore, where measured data do not exist. In this case, using the model requires only to know the seven parameters mentioned above, the measuring of which does not require a meteorological station.
