Light tracing system for solar energy collector

This invention provides the automatic light tracking system for the solar heat collector, which includes the solar panel, the frame, the seat body, the small photoelectric board set, the elevation angle correction device and the judge logic unit, wherein the seat body fixes the whole system, the arc rail face distributed small photoelectric board set is fixed on the frame, this invention locates the whole system by making the small photoelectric board set arc rail face confront to the positive solar sunshine railway parallel direction, and uses the small photoelectric board to read the current data for the judge logic unit to make decision, and makes the stopping, positively rotating or reversal action demand on the step motor of the elevation angle regulator until the solar panel positively confronts to the solar, and the judge logic unit still continuously watches the phototonus sensing data and reacts immediately.
