TITLE

Studies of Shading Effects on the Performances of a Photovoltaic Array

ABSTRACT

Photovoltaic systems are vulnerable to the change of climatic conditions (temperature and irradiance). They cause a declination in power generation efficiency and reliability. The variation is commonly caused by uniform and non-uniform partial shading. The aim of this paper is to present the non-uniform partial shading impact on the performances of a photovoltaic (PV) generator. Hence, a theoretical modeling of a generator composed of a two series PV panels is presented. The first part provides literature review with mathematical model. The second section offers details of the simulation analysis under diverse partial shading conditions.
