Assessment of shading effects in photovoltaic modules

Abstract:

This paper reviews and analyzes the behavior of a photovoltaic device (cell or module) under partial shading conditions. To do this, we implement a simulation model in an open tool (MATLAB/Simulink®) that takes into account the electrical and thermal equations of the photovoltaic device. The knowledge of the behavior of PV device under partial shading conditions is a main topic to optimize its operation. Simulations carried out taking into account the weather conditions (irradiance, ambient temperature and wind speed) as well as suitable time to analyze both transient and steady state. © 2011 IEEE.
