Abstract:
A solar power system comprising:a mirror configured to receive and concentrate solar energy; a mirror positioning mechanism coupled to the mirror and configured to adjust a position of the mirror; a receiver coupled to the mirror and configured to receive the concentrated solar energy from the mirror, the receiver being divided into a plurality of sectors, each of the sectors receiving a portion of the concentrated solar energy; a plurality of sensors, each of the sensors being individually coupled to an associated one of the sectors and operable for generating a sensor signal indicative of an amount of energy transmitted into the associated one of the sectors; and a controller coupled to the mirror positioning mechanism and the sensors, the controller receiving the sensor signals and determining a differential indicative of a difference in a flow of energy into the sectors, the controller controlling the mirror positioning mechanism in response to the differential to affect the concentrated solar energy that is transmitted into the receiver and maintain the differential below a predetermined differential limit.
