ABSTRACT:
A device for detecting a sunbeam incident angle comprises at least one pair of solar cells disposed to be perpendicular to each other, wherein the short-circuit currents flowing in the respective solar cells in the pair are detected, a relative ratio between the detected short circuit-currents is computed, and the sunbeam incident angle is detected on the basis of that relative ratio.
