Abstract
A tracking concentrator with a positioning system for alternately aiming the tracking solar concentrator based on the sun or a database is disclosed. The preferred positioning system comprises a sensor adapted to detect an incident light level; a tracking database comprising solar angle information; an orientation processor; one or more actuators for aiming the one or more optical elements based on the orientation processor; wherein the orientation processor is configured to track the sun based on (a) the receiver if the sensed light level exceeds a determined threshold, and (b) the tracking database if the sensed light level does not exceed the determined threshold.
