Maximizing Solar Array Output Power Under PS Using Shifting Arrangement Reconfiguration

Abstract

In recent years, there have been several proposed solutions to mitigate the negative impact of Partial shading (PS) on the performance of photovoltaic (PV) systems. Achieving maximum energy harvesting is crucial for increasing solar unit efficiency, but this is influenced by several factors such as power electronic device configuration, climate change, and unit size. Various configurations like series, parallels, series-parallel, total-cross-tied, bridge-linked, and honeycomb can be helpful, but they may also have drawbacks such as low shade dispersion, mismatch, and line losses. To address these issues, array reconfiguration has been successful, and this paper examines the current scenario and improvements in PV system reconfiguration. A new technique called Shifting Arrangement (SA) reconfiguration is proposed here to enhance the output performance of photovoltaic solar panels. A comparison is made between the performance of the proposed physical reconfiguration and conventional array configurations, analyzing their Fill Factor (FF), Mismatch Loss (ML), and Global Maximum Power (GMP).
