The solution of the geometric relationships pertinent to an analysis of the shading of a surface at any tilt or azimuth is presented. The approach taken was to use a rotational matrix to convert the solar position relative to the earth to solar position relative to the tilted surface. The derived sun angles are the three components of the angle of incidence of beam radiation in an orthogonal cartesian coordinate system relative to the normal to the tilted surface. Shading factors are developed from these angles for overhangs and side fins of restricted geometry. The algorithms are especially suited to programmable calculator use.
