Experimental study of the effect of fully shading on the Solar PV module performance

Abstract

Experimental tests were performed to study the effects of shading for different string inside the photovoltaic (PV) panels, power equipped with different number of diodes from the same manufacturer as of solar panel. The IV curve for all cases were recorded to see how the bypass diodes will reduce the effects of shading.The case for 3 by pass diode show the best performance of solar PV module under shading phenomena.
