When there are ground mount panels pretty much all the NEC rules are the same. The panel frames must be connected back to the house grounding system. Approved grounding connections to the panel frames must be used Etc. Where things get a little ‘interesting’ is whether there should be a grounding electrode at the.

The Grounding conductor of the PV array must be bonded with the building equipment ground. In addition, it is permitted to have additional grounding electrodes tied directly to the PV Grounding Conductor. Traditional: Daisy Chained Copper Wire between components. Grounding solar panel frames and mounts – Traditional Daisy Chain.
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.
A PV system is defined as a grounded system when one of the DC conductors (either positive or negative) is connected to the grounding system, which in turn is connected to the earth. The conductor that is grounded usually depends on the PV module technology.
The equipment in direct current (DC) portions of the PV system may be grounded using conductors as outlined above with appropriate connections to each metal surface. In general, when a copper wire is connected to a metal surface to be grounded, some sort of certified/listed grounding device must be used.
Before discussing the subject of grounding, the term “grounding” requires definition. There are two types of grounding in electrical and PV systems—equipment grounding and system grounding. Equipment grounding is known in the ROW as safety grounding or protective earthing.
Therefore, you must ground solar with the right wire sizes. Article 690 of the NEC mandates that #8 AWG or #6 AWG are the smallest wires that can be used with grid tied solar panels and inverter systems, and for solar panel output circuits, #10 or #12 AWG are allowed.
