The use of relative sunshine duration and cloud cover for the prediction of solar radiation has been the tool used by researchers. High values of correlation coefficients exist between clearness index with relative sunshine duration and cloud cover in a proposed new model equations. In this work, fourteen meteorological stations: Bauchi, Bida, Enugu, Gusau, Ikom, Jos, Kano, Maiduguri, Minna, Nguru, Yelwa, Yola and Zaria were considered. For most of the stations studied, adjusted coefficient of determination, was obtained, standard error of estimate Se < 0.005 and largest percentage error, except for Gusau and Zaria which have 0.3% and 2.9% respectively when seasonal variations are considered.
