Abstract – Solar energy is catching on all over the world. People like photovoltaic (PV) systems because they turn sunlight into electricity pretty efficiently. Homeowners, manufacturers, and businesses all find them useful. To really make PV panels work well, you’ve got to make sure they’re in spots with lots of sunlight and not too much shade. Most folks stick them on rooftops to keep shading to a minimum, butthat leaves the panels exposed to lightning strikes whenstormsroll through. To tackle that risk, engineers add direct lightning protection.

This paper digs into those direct lightning protection strategies, especially the role oftheearthgridand whatmakes it work well. It also introduces a new way of laying out lightning masts, designed for PV systems with east-west aligned panels packed closely togethersomething there isn’t much published research on yet. Adetailedcasestudy backs up the equations used for designing around direct lightning strikes. Plus, using equations 2 to 12 makes life easier for designers, helping them stay lightning compliant with the rolling sphere method.

This paper dives into the design and analysis of a Solar High Mast Lighting System, paying close attention to extra loading, structural stability, and how well thesystem works. Itsuggests some upgrades to boost the mast’s ability to handle loads and make sure it runs safely, reliably, andsustainablyinreal-world weather.
