Abstract
The main objective of this study was to provide evaluation of different solar radiation models,
which could be helpful in the selection of the most appropriate and accurate model based on the
available sunshine dataǰin the year 010 and 013. Statistical indicators were used to assess models’
performance. The results showed that the mathematical models most suitable for assessing the
radiation from sunshine duration in two years are Almorox and Hontoria mathematical models. In the
yearǰ2010 where the MBE, MARE, RMSRE, RRMSE, erMAX and t-stat is -0.279 -0.005 0.004 1.316 -0.005,
respectively, and in the yearǰ2013 where the MBE, MARE, RMSRE, RRMSE, erMAX and t-stat is -1.008 -
0.029 0.004 -0.029 1.067 and 0.28, respectively.
