Studies and Analysis of Effects of Shading on the Performance of a Solar-Photovoltaic System

This paper presents the studies on the solar photovoltaic system in the partial shading conditions. The standalone solar photovoltaic system for residential application of 2 kW power rating is considered in the system analysis. The proposed system is using a set of batteries for energy storage with a flyback dc-dc converter and a single phase voltage source inverter is designed with the controller to regulate the power quality at the consumer end. The studies are carried out as case studies on the different conditions of the shading and results are presented to analyze the PV output power and evaluate the overall system performance. Based on the results obtained few measures are suggested to keep the check on the performance in such conditions.
