Why PV Plants Are Surge Magnets
Wide area, tall structures, long DC cables.

Geometry
Large ground-mount or rooftop arrays act like wide collectors for lightning electromagnetic effects.
Cable length
Long DC string runs and AC collection circuits import surges into inverters and combiner boxes.
Downtime cost
Inverter replacements and generation loss quickly dwarf SPD costs.
