Quick one, if we bond are we bonding all the metal of the PV and then taking a cable to the Earth of the municipality. I.e the main earth bar of the AC DB board ?

If so are we now bonding AC and DC so if there is an Earth fault the panels will now be with the AC potential.

If the above is correct...

What if it is a ground mount system, now the metal frame is at a higher potential to true earth so if you standing on the earth and touch this now risen above earth potential PV panel you will be shocked ?
