A solar tracking device is mounted above a skylight of a building. An
array of mirrors is rotated at a rate of one revolution per day to
reflect sunlight through the skylight. A control circuit intermittently
adjusts the angular position of the tracking device so that the mirrors
face the sun. A solar array charges an internal energy storage system so
that no external power source is needed. The control circuit within the
tracking device reduces the power requirements at night and when not
moving the tracking device during the daytime to conserve electrical
energy.
