Abstract

Partial shading is a serious obstacle to effective utilization of photovoltaic (PV) systems since it result in significant output power reduction. PV array reconfiguration strategy is one of the most efficient used solutions to overcome negative effect caused by the partial shading in PV systems. This paper presents a comprehensive review of the major existing PV array reconfigurations approaches which are used to overcome the problem of partial shading. The different approaches are evaluated and compared according to their techniques, advantages and drawbacks. This work represents an interesting reference for researchers working in the field and a simple guide that serves as help for beginners on PV array reconfiguration.
