Abstract
In the present work, the shading effect of a south building on the aperture of a solar device in the north latitudes is theoretically investigated. A mathematical model to calculate the instantaneous value of shaded area as a function of building horizontal distance, neight, width and the angle of deviation from south direction as well as aperture dimensions has been obtained. The shading factor, which is the ratio between the actual total incident solar radiation and that without shading on the aperture, has been calculated for different geometrical parameters. The annual average shading factor, which may be considered as a reasonable measure of the shading effect is also given in terms of the system dimensionless parameters.
