ABSTRACT:
This invention relates to a sun tracking device which provides efficient utilization of sun light by tracking the motion of the sun, so that the light of the sun may be received in a sun light utilization device for performing solar power generation or solar power collection. Efficient utilization of solar power is achieved by using a rotatable table floatingly supported on the surface of a liquid, with a pair of solar cells mounted on this table which also carries the solar power utilization device. The solar cells have different light receiving directions, and function as a sun light position detecting means. The table is rotated according to the output of the solar cells by means of screws, pumps, drive belts, or the like.
