Problems with adding more panels

[Hedges]

I don't think there is any problem with splicing or branching ground wires.
I do that in a lot of places.
Ground wire should have sufficient ampacity for the source. AC circuits, smaller than current carrying conductors because breaker will trip. PV DC, current will never shut off so sized to carry continuous current.

Something about ground rods and service entrance may call for 1 wire or irrevocable bonding.
Elsewhere it goes to busbars and many circuits.

Thanks for your quick reply! I appreciate your help.
