6 FAQs about [Photovoltaic panels and bracket grounding requirements]

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)].

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.

Why is proper grounding of a photovoltaic power system important?

Proper grounding of a photovoltaic (PV) power system is critical to ensuring the safety of the public during the installation’s decades-long life. Although all components of a PV system may not be fully functional for this period of time, the basic PV module can produce potentially dangerous currents and voltages for the life of the system.

Does a solar hot water system need a grounding system?

Section 690.43 of the NEC requires that PV systems have equipment grounding systems when there are any exposed metal or conductive surfaces that may become energized. This requirement applies to PV systems operating at any voltage, including small standalone 12-volt PV systems and even a 6-volt, PV-powered water pump on a solar hot water system.

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 ungrounded PV systems need ground protection?

In all cases, an ungrounded array must be provided with equivalent protection for ground faults, as required by NEC 690.35. 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.
