PV Grounding & Wiring to Inverter | DIY Solar Power Forum
The panels in each separate array are bonded together. From there each array utilizes a ground wire along with the PV wire. The PV''s remain separate and go to their respective DC Disconnects, but the ground can be combined into one. Then the two PV sets along with the one combined ground run to the inverter in the shed.

Definitely run a ground wire so you can bond PV panel frames to chassis of inverter or charge controller. That protects against DC shock in case of a short at the array (including cracked panel and water). It also protects against against AC shock; many AIO inverters couple AC onto PV wires, and there is capacitance to frame.
grounding question and confusion

No current flows through the GEC to earth. The green ground wire never carries any current unless you have a fault as shown above. The fault current then uses the green G conductor to return the current to the source. That third wire or Green wire use to be called Equipment Ground Conductor (EGC) . There is that damn word Ground again.

What bare copper wire should I use for solar panel grounding?
Throughout this guide, we’ve covered the key aspects of solar panel grounding, from understanding regulatory requirements to avoiding common mistakes. Remember, the most crucial takeaway is to always use #6 AWG bare copper wire for outdoor grounding. This simple yet vital detail can make the difference between passing and failing an inspection.
How to wire a solar panel?
Following this, you should connect a grounding wire to the grounding rod. The wire should be made of copper or galvanized steel and should be at least 8 feet long. Use a wrench to tighten the connection between the wire and the rod. In the third step, run the grounding wire from the rod to your solar panel array.
How do solar panels use integrated grounding mechanisms?
Solar panels with integrated grounding mechanisms use metal frames as the grounding conductor. The frames are connected to a grounding electrode, and the grounding path is established through the frames. This method is convenient and reduces the need for additional grounding components.
Do solar PV systems need to be grounded?
Key points from the NEC: The code requires all non-current-carrying metal parts of the solar PV system to be grounded. It specifies the minimum size of grounding conductors (more on this later). The NEC also outlines requirements for grounding electrodes (like ground rods) and how they should be installed.
How do you ground a solar racking system?
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.
