Grounding conductors are the wires or cables that connect the photovoltaic brackets to the grounding electrode system. They should be made of a conductive material, such as copper or aluminum, and have a sufficient cross-sectional area to carry the fault current safely. . When a photovoltaic system is properly grounded, it provides a path of least resistance for electrical current to flow safely into the ground in case of a short circuit or other electrical issue. Personally I'd ground the panels. This simple yet critical detail can save you time, money, and headaches down the road. Whether you're a DIY enthusiast or just want to understand the process better, this. . If yes, do I ground it by driving a grounding rod into the ground beside the array and running a bare copper wire from one panel down to the rod in the ground? Do I need to connect all panels using the bare copper wire? Or, do I not ground at all, and run the ground in the trench with the PV wires. . When it comes to connecting ground wires in solar panel installations, copper proves to be an indispensable element.
