Automated Solar Panel adjuster

Solar panels are mounted on a large rack. This rack needs to be rotated during the day to follow the sun and thus achieve a maximum charge. Although this could be done with less efficiency with a timer, it is often necessary to get maximum charge. This would also not move the panel if there were no sun as to not waste power. This would be done by using 2 optical sensors. One would detect if it was a sunny day, and the other would detect how much sunlight was hitting the panels. If it was a sunny day and the sunlight hitting the panels had decreased by a certain percentage then the motor attached to the rack would rotate the rack until the sunlight was sufficiently increased. I was going to use a National

Instrument MYRIO with a programmable ZYNQ FPGA as the controller. The motor would need to be isolated from the controller through the use of relay or optical isolator. This was just my idea I am very open to whatever you guys want to do

Parts required:

• NI MYRIO controller with ZYNQ FPGA
• 2 optical sensors
• Actuator motor arm
• Isolator relay

Power interface with solar system for powering the controller
