Abstract
Six silicon solar cells are arranged in three pairs on three mutually perpendicular planes. One cell of each pair will be exposed to both the direct rays of the sun and the diffuse light radiation incident from the same direction, depending upon the orientation of the device and the time of day. The other cells of each pair will be exposed only to the diffuse radiation on their respective planes. The differences in the measured radiation on each plane are squared, summed, and the square root of the sum then taken to determine the actual value of the direct rays of the sun.
