An analytical solution is presented for calculation of the integrated daily beam radiation on a surface at any tilt and azimuth which is shaded by a simple overhang. The solution involves the determination of an integrated shaded tilted surface to horizontal surface insolation ratio, anti R/sub bs/, similar to the ratio, anti R/sub b/, defined by Klein for an unshaded tilted surface. Four hour angles must be calculated, in addition to the sunrise and sunset hour angles, which correspond to transition to or from full shading and no shading of the surface. These hour angles represent the limits of five integration segments for which solutions can be defined. The resulting ratio, anti R/sub bs/, can be substituted for anti R/sub b/ in calculating the total radiation on a shaded surface.
