Either carefully abrade away the anodizing at the ground point or use sharp-edged stainless-steel
star washers between the ring lug and the surface (see
anodized layer. You can apply these same methods to painted surfaces as well.

Grounding Method

Use a ring tongue terminal and 4 AWG wire to make the connection to the mounting frame of the
solar panel. The ring tongue terminal should fit a #10 stud (similar to Molex

Make the grounding conductor no longer than is necessary to safely and neatly make the
connection between the panel frame and the earth grounding electrode. The connection at the
earth-grounding electrode end of the grounding conductor varies depending upon the style of
