Design and Installation of a Reconfiguration System for Solar PV Panels to Reduce the Effect of Partial Shading

Abstract

Currently, there has been an increased installation of solar panels to generate clean electrical energy and reduce electricity costs of consumers. However, due to environmental limitations, there may be instances of partial shading on the solar panels, leading to a decrease in the overall electricity production efficiency of the system. To address this issue, this study is conducted on designing and installing a reconfiguration system for solar PV panels to mitigate the impact of partial shading. There are four types of solar panel array configurations considered in this work consisting of series-parallel type A, series-parallel type B, total cross-tied type A, and total cross-tied type B. Additionally, eight patterns of partial shading are considered to examine the effectiveness of the reconfiguration system in reducing the impact of partial shading and enhancing power generation efficiency. The results revealed that the total cross-tied configuration presented the highest power generation efficiency when compared to the series-parallel configuration.
