Abstract: In order to obtain the most appropriate parametric model for estimating solar radiation in Anhui Province, based on the observational solar radiation and sunshine hours of 10 radiation stations in Anhui Province and its surrounding regions from 1961 to 2012, the accuracy of 7 solar radiation models were compared and analyzed. Results showed that: the model which was modified based on the observational data of Anhui Province and its surrounding regions was more accurate than the other models and was most applicable for Anhui Province. The estimated monthly average solar radiation based on the modified model of Hefei station and Tunxi station was mostly consistent with the measured values. The mean absolute relative error for the two stations was less than 2.0% and 3.5% respectively. This study provided a scientific basis for carrying out the solar energy resource assessment.
