ABSTRACT:
A parabolic-trough solar collector system is disclosed, with each collector driven to track the sun using a ring driven in centerless fashion. The parabolic troughs are made of laminated plywood or molded or formed of plastics or metals. The drive motor moves a flexible belt, i.e., chain or cable, which is routed about the drive ring on each collector. The motion of the cable moves all drive rings together to track the sun. A photodetector senses the position of the sun and provides the signal needed to drive the collectors in the correct direction.
