Correction for Installation Error and Discrete-Time Tracking for Solar Tracker

In order to improve the tracking precision and efficiency of the solar tracker,correction of installation error and tracking of discrete-time points for the tracker was proposed. First of all,the overall structure of the two axes pv tracking system was analyzed and designed. Then,using the sun azimuth Angle and height Angle calculation formula under correction of installation error,trajectory algorithm control was revised. In view of change rule of the sun altitude angle and azimuth angle,altitude Angle use trajectory tracking and azimuth angle use the mixed tracking mode of photoelectric and trajectory tracking; Tracking time point use the non-uniform discrete distribution. The text show that correction of Installation error and discrete tracking method have important practical significance for improving the utilization of solar energy.
