Bonding (grounding) solar panels

[Dylboy]

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 ?

Earth is earth - How do you test if your earth is good - You test to the " god made earth" and your " man made earth" and if you get 0 Ohm you have an excellent earth - You reference is the earth , the soil that you stand on and plant flowers in

If your ground mount system is metal and the poles are buried in the earth then it is more than likely going to have a good earth and the frame cannot be at a higher potential than the earth as it will be at the same potential because it is in the earth - The only time it can be at a higher potential is if the earthing is not good.

There is no such thing as DC earth and AC earth - It is all earth
