Abstract

This study compared the results of three isotropic sky models for estimating solar radiation on tilted surfaces with experimental data. The three isotropic models considered were Liu & Jordan, Badescu and Koronakis models. Scilab computational tool was used in assessing the performance of each model. The accuracy of the models was determined using mean bias error (MBE), root mean square error (RMSE), mean absolute percentage error (MAPE) and the t-statistics techniques. Liu and Jordan model was recommended for estimating global solar radiation at Nsukka, Nigeria, having recorded the least values of MBE and t-stat of -0.0127Wh/m2 and 3.3947 respectively.
