Grounding & Bonding — Why it is done And How to Install
The Code defi nes "grounding" as the connecting to ground or to a conductive body that extends the ground connection — and the Code defi nes "ground" as the earth. Basically, grounding is
ON THE GROUNDING AND BONDING OF SOLAR PHOTOVOLTAIC
Solar PV systems are still permitted to be grounded, per 690.41(A)(1) and (5), and, for those PV systems that are, the dc grounded conductor is directly coupled (or coupled through electronic

6 FAQs about [Specification requirements for photovoltaic panel grounding jumpers]
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 PV modules need a grounding conductor?
Metal parts of PV module frames, PV equipment, and enclosures containing PV system ac and dc conductors must be connected to the circuit equipment grounding conductor per 690.43 (A) through (D). (A) Photovoltaic Module Mounting Systems and Devices.
Does a PV system need a grounding electrode?
A building or structure supporting a PV system must have a grounding electrode system installed [690.47 (A)]. PV systems are grounded when the PV inverter output ac circuit equipment grounding conductor terminates to the distribution equipment grounding conductor terminal [690.47 (A) (1).
What sized grounding conductor is required for a PV system DC Circuit?
Where no overcurrent protective device is required [690.9 (A) (1)], the equipment grounding conductor for the PV system dc circuit must be sized per Table 250.122 based on an assumed overcurrent protective device for the circuit sized per 690.9 (B).
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.
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.
