Abstract
The present invention is a solar tracking system which utilizes three supports arranged in a generally tripod configuration. In one embodiment, two of the supports are linear actuators, and the third support is a stationary universally pivoting joint such as a ball and socket joint. The tracking system may include cross-supports for increased stability, a linear rail for additional range of motion, and a mounting base to facilitate installation. This solar tracking system offers a stable, cost-effective design which is also capable of moving the solar module into an optional stowed position.
Claims19
A solar tracking system for moving a solar energy module, said solar energy module having an energy collection surface, comprising:
- a first support arm comprising a first linear actuator having first and second ends, wherein said first end of said first linear actuator is coupled to said solar energy module;
- a second support arm having first and second ends, wherein said first end of said second support arm is coupled to said solar energy module;
- and
- a stationary support having a top end and a bottom end, wherein said top end is coupled to said solar energy module by a universally pivoting joint.
A method of moving a solar module, wherein said solar module is coupled to a first linear actuator, a second support arm, a stationary support, and a control system, wherein said method of moving comprises:
- providing control signals from said control system to said first linear actuator and to said second support arm;
- moving said first actuator from a first position to a second position;
- and
- moving said second support arm from a first position to a second position.
