Solar Panel Grounding Lug and Clips
LARGE Grounding Clips and Washers are used on the rails and under the solar panels. with many bumps on the washers and clips to pierce the anodized layer of the aluminum rails and solar panel's frame.
If so, when the thunderstorm weather,the grounding system can take a return circuit to the earth ground.and then protect the solar modules.
