Experimentation, Simulation & Analysis of Partial Shading Effect in Solar Modules

ABSTRACT The impact of partial shading conditions on photovoltaic modules is investigated here, and a novel Master‐Slave configuration is proposed to mitigate the associated performance losses. The modified method achieves the global maximum at an enhanced PV voltage and current, employing a Master‐Slave setup that supplements the under‐generated power of the slaves, resulting in a maximum increase of 51.9% in power output when tested at a 20% fixed partially shaded condition. Unlike conventional bypass diode (BPD) or reconfiguration methods, the proposed system ensures better voltage stability and reduces reverse bias conditions and thermal stress. Simulation results, mathematical modeling, and experimental validation are provided in this paper.
