Solar energy plays an effective role in human’s life. This study aims to determine the energy potential of solar radiation in Chaharmahal va Bakhtiari Province. The radiation and climate survey data gathered in a daily scale were used to determine the radiation estimate model and find the amount of radiation in Chaharmahal va Bakhtiari Province. The amount of radiation at 13 stations was estimated using experimental models and statistical relationships of radiation with other elements of climate. The reliability of models and the accuracy of the estimated values were confirmed by using the mean bias error and root mean square errors and the correlation between the predicted and observed values. Radiation estimates that used Angstrom models based on the lighting coefficient had more credibility in estimating the amount of radiation in the no-radiometer station. The study of the correlation coefficient between estimated radiation and radiation measurement also showed that in stations which lighting coefficient is used to estimate the amount of radiation, the correlation coefficient was stronger and more meaningful than that of other stations used, based on other climatic parameters such as cloudiness, humidity and temperature.
