Abstract
Reconfiguration process is very important in terms of efficiency in photovoltaic (PV) arrays under especially in partial shading conditions. Although there are some studies for reconfiguration process in the literature, they are difficult and complex. In this study, full or partial shading effects on arrays are examined and presented for reconfiguration of PV arrays. System performance is intended to increase by making image-processing based moving shadow analysis. Reconfiguration of PV arrays is provided with proposed approach under the partial shading conditions without information of current (I), voltage (V) and power (P) which is quite difficult to measure. Experimental results are verified by using a video image obtained from a real PV array and effective results are obtained.
