Characteristics of Photovoltaic Modules Under Uniform Insolation and Partially Shaded Conditions

R. Reshma Gopi, S. Sreejith

Abstract


Abstract
The maximum power that could be generated by a Photovoltaic (PV) System is depends on temperature and irradiance variations. Often, the PV arrays get shadowed by clouds, towers, trees and telephone poles. In order to obtain full utilization from the PV array, it is necessary to analyze the characteristics of PV system. This study deals with a MATLAB based modeling and simulation of a photo voltaic cell under normal (without partial shading) and partially shaded conditions to analyze the electrical characteristics. This study also investigates the reverse bias characteristics since it is significant during fault conditions and high frequency applications.

Keywords: choppers, DC–DC converter, inverters, maximum power point tracking, photovoltaic cells
