    Study of the statistical indicators of global solar radiation in Algeria using the Angström model
    (2019-02-24) Anouar BELLA BACI; Mohamed SALMI
    This study was conducted to estimate the monthly global solar radiation in the Algerian territory using the Angström model, for seven sites in Algeria, namely: Algiers, Ain Bessem, Constantine , Oran, Djelfa, Mascara, and Tamanrasset. The models are based on global solar radiation in the horizontal surface as well as sunshine hours . To evaluate the results obtained by the different sites we calculated the following relative average algebraic differences: MAE, MBE and RMSE The results show a remarkable agreement between the measured and computed values, especially in Tamanrasset site where the slope is of the order of 1
