With regards to earthing your solar panels after installation.
I have micro-inverters so there is AC power running from the roof into the DB board.
To earth your rails / panels can I now link each rail with a system ground copper wire, and then run that into the junction box on the roof, which is bringing the ground wire from the DB board up to the roof. The system has its own AC breaker(s) in between the DB and the panels / inverter so to speak to completely isolate it if needed.
I see the "normal" panels have a copper spike in the ground, I'm guessing that's for DC power running from the roof?
