PV Panels - to Earth or not to Earth

Hi,

I am in the process of installing my lovely new panels to my DIY ground mount.

The panels are mounted onto an Aluminium rail system which in turn is fitted to a substantial timber frame - my next step is to connect them up.

The panel manufacturer has left holes in the back of the panels for earth connections, but my friendly electrician who is quite experienced with PV systems tells me that the firm he works for do not use these connections and don't earth the (many) panels that they fit.

Do we have any experience here regarding earthing (or not) and does the forum have a view ?

Regards

P

If un-earthed where would a lightning strike go? My guess is in through inverter etc, not good.
Just a thought.
