An Experimental Investigation on Photovoltaic Array Power Output Affected by the Different Partial Shading Conditions

This paper presents an experimental investigation on photovoltaic array (PV array) power output affected by partial shading conditions (PSCs). An experiment setup of a PV with series configuration using 2 × 4 modules modules) was built. The loss due to the effect first cells cell) connected bypass diodes each module, installed in horizontal direction, evaluated. Depending direction sun relative configuration, percentage measured during test and recorded current voltage array. performance evaluation configurations is referred respect values maximum voltage, current, output, losses fill factor (FF). results show that 44% affects more than 80%.
