ADAPTIVE PARTIAL SHADING DETERMINANT MEHTOD FOR SOLAR ARRAY SYSTEM AND PHOTOVOLTAIC POWER GENERATION DEVICE USING THE METHOD THEREOF

摘要

The present invention relates to a method for determining adaptive partial shade for a solar array system, the method comprising: performing global peak scanning (GPS) on a solar array including a plurality of solar panels; identifying a plurality of regions divided according to at least one reference voltage on the voltage versus power graph for the solar array; and determining whether to re-perform the global peak scanning based on an area in which the solar array currently operates among the plurality of areas and the calculated reference power.
