Abstract: A solar collector controller that can process solar field control commands can include a network interface that can receive a variable-length data packet with a collector controller. The collector controller can control one or more solar collectors. In addition, the variable-length data packet can include a header segment identifying a command to be performed by the collector controller and a data segment having one or more parameters associated with the command. The data segment can have a length that depends on a type of the command. Moreover, the solar collector controller can include a processor that can execute the command in response to receiving the data packet.

Abstract: 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.
