METHOD AND APPARATUS FOR CONTROLLING PHOTOVOLTAIC PLANT OUTPUT USING LAGGING OR LEADING TRACKING ANGLE

摘要

A method and system (100) for operating a tracker (110) to cause a solar module (115) to track a position of the sun at a first angle of incidence, and, in response to identification of a lag or lead trigger condition, determine a second angle of incidence calculated by increasing or decreasing the first angle of incidence by a lagging or leading factor so as to lower electrical current output of the solar module (115), and thereafter operating the tracker (110) to cause the solar module (115) to track the position of the sun at the second angle of incidence.
