In this study, anexperimental study was carried out to compare the tracking performance of themaximum power point tracking algorithms under partial shading conditions. Thesealgorithms are Stochastics Beam Search, Simulated Annealing, Fractional OpenCircuit Voltage and Stochastics Hill Climbing. The test setup consisted of 4series connected solar panels, Buck type DC/DC converter, microcontroller andPC. Current/Voltage (I/V) characteristic of the PV system was collected underdifferent shading scenarios and these data were used to compare the success ofthe algorithms in the MATLAB environment. The comparison results show that theStochastics Beam Search algorithm finds the highest power point in all shadingconditions with high speed and accurcy.
