Estimate of the Direct, Diffuse and Global Solar Radiations

The purpose of this work is to develop the models, which will be used to predict the daily direct, diffuse and global solar radiation data for clear skies by combining simulations through these models, and climatology measured of the station of Energetic Laboratory of the Faculty of Sciences, Abdelmalek Essaadi University, Tetouan, in northern Morocco. We used two empirical models: Capderou [4, 19, 23, 26] and Perrin& Brichambaut ( [1 pages 74-90, 3, 36]) models; the latter uses meteorological data: of sunshine duration, The Linke Turbidity Factor [19, 21], albedo. The results obtained indicate that the proposed models can successfully be used for the estimation of the daily solar radiation data for the days considered. In addition, these models can be generalized for an application of PV systems in Solar Buildings.
