Yola is located between Longitudes 12° 12'E, 12° 33'E of the Prime Meridian and between Latitudes 09° 12'N, 09° 19'N of the Equator. The performance of 10 empirical models were used to estimate global solar radiation for the region. Model 4 model was found as the most accurate model for the prediction of global solar radiation on a horizontal surface for Yola. The MPE, RMSE and MBE were 0.0628, - 0.012 MJ/m2 and 0.0464 MJ/m2 respectively. This model can be described for Yola. After comparing the measured global radiation values with the predicted values at any particular month for validation of the established model, these values laid around the straight line. This means that the generalized model is valid for the geographical and meteorological data of Yola.
