a solar tracking system having particular utility for insuring that a relatively lightweight solar collector is properly positioned with respect to the sun . a parabolic reflector surface is included to provide a line of focus of the sunlight directed toward a cylindrical energy absorption tube . photovoltaic cells provided on either side of the energy absorption tube are directed toward the parabolic reflector surface . a reversible motor is electrically connected to the cells and physically connected to the reflector system for correcting any misalignment with respect to the sun . the reversible motor can be used as the sole means for powering the tracking system or can be used in conjunction with an outside power source .
