NEC 690.45(A) requires that equipment grounding conductors for PV source and output circuits be sized in accordance with NEC table 250.122, which allows for a smaller gauge ground wire, such as a # 10 or #12 AWG, to be used in this portion of the PV system. This equipment-grounding requirement is only for.
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.

6 FAQs about [Specifications for ground wire welding of photovoltaic panels]
What is electrical & PV grounding?
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.
Does a photovoltaic system have a DC grounding system?
Photovoltaic systems having dc circuits and ac circuits with no direct connection between the dc grounded conductor and ac grounded conductor shall have a dc grounding system. The dc grounding system shall be bonded to the ac grounding system by one of the methods in (1), (2), or (3).
Do I need a grounding electrode for a PV array?
While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter’s grounding bus bar.
What is a solar substation grounding guide?
Abstract: This guide is primarily concerned with the grounding system design for photovoltaic solar power plants that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80.
What is a grounding point of a PV inverter?
The grounding point of the inverter is connected onwards to the grounding system or grounding electrode of the residential facility or building (see figure below). 15) PV circuits having 30V or 8A more shall be provided with a ground-fault protection device (GFPD). Nowadays, in general, this is a built-in function of inverters.
What is a grounded PV system?
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.
