Enclosed solar collector

A solar collector includes a plurality of elongated parabolic reflectors mounted within a glass-topped enclosure for pivotal movement such that each reflector is incrementally pivoted throughout the course of a day to remain substantially perpendicular to the sun. The incremental pivotal movement is caused by a motor energized from a solar switch having solar cells that also pivot throughout the day so that in one position of the switch, no electricity is being generated and transferred to the motor, but in a second position, the switch receives solar radiation and energizes the motor to again incrementally pivot each reflector along with the solar switch. The reflectors are therefore incrementally pivoted throughout the course of a day to follow the sun for optimal collection of solar radiation which is used to heat liquid carried by tubes positioned at the axis of generation of the parabolic reflectors and / or strips of solar cell material so that electricity can be generated alone, liquid heated alone, or liquid heated and electricity generated simultaneously.

Some of the most expensive components within a solar tracker go into the precision drive system which accurately follows the motion of the sun. This invention reduces the complexity and the required number of drive components in a tracker optimized for reflective dishes. With this invention a single drive motor can keep 20 or more large reflective dishes accurately tracking the sun, whereas 40 drive motors with more complex control systems would typically be required for the same number of dishes. In addition this invention allows for complete inversion of the dishes, which helps reduce dust accumulation on the optical surfaces and lowers wind resistance during storms.
