Abstract
Abstract A solar cell panel with a cover plate which defines a plurality of apertures with light-reflective surfaces. The shapes of the apertures and the spacings between them are chosen to vary the illumination level of the cells as a function of the degree of inclination of the plate with respect to the normal light direction.
