AbstractA tracking system is provided for a roof-mounted solar array. The system includes a sensor mechanism for sensing an orientation of the sun relative to the solar array, and a controller connected to the sensor mechanism that generates a signal that represents an optimal tilt angle of the solar array relative to the orientation of the sun. An actuator connected to the controller receives the signal from the controller and adjusts the tilt angle of the solar array in response to the received signal.
