Abstract

Partially shaded solar modules are common in all types of photovoltaic (PV) systems. In many circumstances, passing clouds, surrounding buildings and towers, trees, or the shadow of one solar array on the other obscure the PV arrays completely or partially. The most important factor influencing the performance of a solar photovoltaic system is the solar radiation that contacts the panel surface. The primary cause of panel performance degradation is surface shading. Solar panels' lifetime and efficiency are reduced when they are partially shaded. This article includes a simulation-based assessment of a PV panel with and without a bypass diode under partial shadowing. Our research study examines the fluctuation in the features of a series-parallel solar array arrangement under partial shade conditions using MATLAB/Simulink-based simulation results.
