As usually, Grounding PV modules is necessary and required  for the solar power ystem.

Are you always worried about your solar panels for  thunderstorm whether?

The UISOLAR Grounding parts include special washers ( diffenert washers for grounding clip, grounding lug and bounding jumper)  with sharp ridges on them that penetrate through the non-conductive coatings of the aluminum module frames and mounting racks. The mounts themselves are then grounded so the entire assembly is grounded.

Customized Grounding components (Both ground washers, groundling lug and Bounding jumper )  are avaiable here.
