In this guide, we'll walk you through the ins and outs of solar panel grounding, covering everything from basic concepts to step-by-step instructions. The most important takeaway? Always use #6 AWG bare copper wire for outdoor grounding to meet National Electric Code requirements and. . 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. This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing. . 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. .
