4. Bonding Solar Panel Frames and Racking. Now, you''ll connect your solar panels and racking to the grounding wire: If your racking system is UL-listed for bonding, connect the grounding conductor to one rail in each row. If not, attach a grounding lug to each panel frame and racking component. Connect these lugs to your main grounding wire.
There is more than one way to satisfy this Rule requirement, e.g. bonding the frame, where the frame is electrically continuous or connecting the bonding conductor, as per Photo B2. Photo B2 shows a bonding conductor that is continuous through the two bonding clamps, so that the panel can be removed without interrupting the continuity of

A decade ago, it was common practice to bond the metal frames of PV modules by drilling and tapping a hole in the aluminum frame of each module, fastening a lay-in lug to each, and then connecting those lugs with a bare, stranded, copper conductor.
There is more than one way to satisfy this Rule requirement, e.g. bonding the frame, where the frame is electrically continuous or connecting the bonding conductor, as per Photo B2.
“Bonding and grounding PV systems ensures public safety, as well as the safety of PV installers and field electricians,” said Andy Zwit, Codes and Standards Manager at ILSCO. Excluding modules, the majority of components in PV systems are bonded like any other electrical system.
The National Electrical Code (NEC) requires bonding electrically conductive materials and equipment to establish an effective ground-fault current path.
