ABSTRACT:
A solar tracker for a solar collector which is angularly oriented by a motor wherein the outputs of two side-by-side photodetectors are discriminated as to three ranges, a first corresponding to a low light or darkness condition; a second corresponding to light intensity lying in an intermediate range; and a third corresponding to light above an intermediate range, direct sunlight. The first output drives the motor to a selected maximum easterly angular position; the second enables the motor to be driven westerly at the earth rotational rate; and the third output, the separate outputs of the two photodetectors, differentially controls the direction of rotation of the motor to effect actual tracking of the sun.
