A solar collector tracking system is provided for maintaining orientation of multiple solar collectors to the sun to provide optimal focusing of solar radiation on a receiver. The system includes a local controller circuit board that contains a sun-tracking algorithm to control the movement of multiple solar collectors to keep them optimally focused on the sun. The system also comprises a separate motor controller for each collector in data line connection with the local controller, and a motor for each collector in power connection with its motor controller. This isolates the local controller from the motor and protects the circuit board against power surges. The local controller allows effective field maintenance using field-replaceable components. Its circuit board is preassembled in a rugged, weather-proof cabinet to minimize the time and work required to prepare and install it in the field. The typical service life of this durable local controller is expected to be 30 years.
