Re: Grounding & Lightning (diagram for review...)
The Air Terminals... Rods spaced along the roof line of the building tied to heavy braided cables that run to earth ground (in rounded curves--sharp right angles can cause lightning to not flow to ground properly--causes higher impedance to current flow).
The idea being it is better to attract lightning to properly grounded conductors than have the lightning strike a chimney or your solar array or electrical wiring/roof/flashing around your home.
A couple of discussions about genset grounding and lightning protection:
