A Study of Photovoltaic Array Characteristics under Various Conditions

Panchal Mandar Rajubhai, Dileep Kumar

Solar Photovoltaic systems are the most promising energy resource of the modern world. Performance of Photovoltaic array is directly affected by some parameters like temperature, irradiance, partial shading condition, series resistance and parallel resistance. Analysis of Photovoltaic array characteristics under above circumstances can help to choose most economical/suitable place for Photovoltaic array installation. This paper presents analysis of Photovoltaic array characteristics and concept of using Bypass diode. Physical simulation model of Photovoltaic array is run by programmed m files with the help of MATLAB/SIMULINK. To analyse characteristics of Photovoltaic array and find maximum power point under different temperature levels, different irradiance levels, partial shading condition and different equivalent circuit parameters is the aim of this paper.
