According to building codes, the holes typically need to be 18″ or 24″ in diameter with a depth ranging between 3-5 feet. The depth depends on the height of the ground mount and local code requirements. You may also damage the module backsheet. Unless required, I would advise against it. That being said, installers are drilling holes on the. . Solar panel/module grounding bolt size? Jinko solar panel has a 4mm hole in its frame for grounding wire connection. Which size bolt should i use for it? M4 or M3? I read somewhere that M4 means 4mm is hole size and bolt diameter is smaller than 4mm, other sites say that M4 bolt means 4mm diameter. . Grounding a solar photovoltaic (PV) system involves establishing a low-resistance conductive pathway that connects the non-current-carrying metal components of the array to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards.
