Abstract

It's widely known that Malaysia's solar photovoltaic systems are vulnerable to lightning strikes due to their installation in open areas with high radiation and lightning density. Lightning strikes can damage the electrical components of these systems, leading to electromagnetic interference and efficiency losses. To study this, a photovoltaic module was simulated and tested under normal and lightning conditions using COMSOL Multiphysics software. Two cases were examined: the effect of different current injection points and various solar cell materials on magnetic field and flux density. Results indicate that under lightning conditions, electromagnetic interference is notably higher compared to normal conditions. Moreover, the placement of current injection points significantly influences electromagnetic interference, impacting induced currents during lightning exposure. Additionally, there's a minor impact on electromagnetic interference from changes in solar cell materials, including Polycrystalline Silicon, Monocrystalline Silicon, and Thin-Film (Gallium Arsenide).
