Solar panel/system earthing help needed.

[collectors]

Hi, i am at the planning stage of a solar panel system & getting a lot of contradiction on earthing. The drawing is the plan & i would say earth ABCD earth of the incoming main as all will have 230'ish volts. But not sure on EFG & weather G is needed.
I am even more interested as i was chatting to next door with solar panels & his son got a shock whilst cleaning them. So, any help with EFG would be appreciated. Plus it would be nice to avoid possible ground loops & lightning problems. Thanks

In the USA your ground wire would be connected to each panel F then follow the output wires to E-D-C-B No new G grounding. Use the building's existing ground. Your country's requirements maybe different.

Two earth rods in close proximity and bonded ABOVE ground thru your wiring system is a bad idea. In the event of a lightning strike It will allow high step potential voltage to travel thru your grounded equipment causing all kinds of damage.

In the US that would be considered an "Auxiliary" ground electrode, not required and therefore not required to be bonded to the building's ground system. Here's a video expaining why not bonding them (or even having that rod in the first place) is a bad idea: https://www.youtube.com/watch?v=gg4wBI7bWgI
