6 FAQs about [Photovoltaic panel grounding wire standard requirements]

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.

What are equipment grounding requirements for PV systems?

Equipment grounding requirements for PV systems are covered in 690.43. These requirements include the bonding and grounding requirements for exposed metal parts of PV systems such as metallic module frames, electrical equipment, and conductor enclosures [690.43 (A)].

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.

Does a PV array need a grounding conductor?

Since the PV array and other electrical equipment in PV system, e.g., inverters, are often located remotely from one another, 690.43 (B) requires that an equipment grounding conductor (EGC) be run from the array to other associated equipment.

Do solar arrays need grounding?

Hi, Do solar arrays (the frames) need grounding? The inverters in most cases are DC (and isolated from mains) and indeed micro-inverters are class 2 with isolated DC inputs from the array. I think if the installation has a TN-C-S earthing system, connecting the roof frame to ground would potentially cause an issue if there was a PEN fault.

Do PV inverters need AC side grounding?

When a PV plant is installed in the distribution feeder, the plant shall meet the IEEE 1547 standard and the interface requirements of the local utility company. Some utility companies require PV inverters to have AC side grounding in order to assure compatibility with their grounding scheme, generally referred to as effective grounding.
