Despite the installation of LPS, the possibility of direct lightning strikes to the solar PV panel frame/structure might still happen. Hence, this paper discusses the grounding strategies for solar PV panels to mitigate hazards from overvoltages when this occurs. In this research project, two strategies are considered for the solar PV assemblies; individual assembly grounding and grouped assemblies grounding. This paper focuses on individual assembly grounding and some preliminary results are presented and discussed.
