6 FAQs about [Photovoltaic solar panel bonding device]

What devices must be listed for bonding PV modules?

(A) Photovoltaic Module Mounting Systems and Devices. Devices used to secure and bond PV module frames to metal support structures and adjacent PV modules must be listed for bonding PV modules.

Why is a PV system bonded?

“Bonding and grounding PV systems ensures public safety, as well as the safety of PV installers and field electricians,” said Andy Zwit, Codes and Standards Manager at ILSCO. Excluding modules, the majority of components in PV systems are bonded like any other electrical system.

Should PV equipment be bonded?

That being said, PV equipment needs to be properly bonded so that the low current flows on metal parts can open smaller string level overcurrent devices, if installed, and also facilitate the operation of dc ground-fault protective devices. Figure 1. Location of Grounding Conductors in a Grounded PV System

Why do solar panels need bonding?

Bonding prevents a host of possible risks and dangers. “Imagine: the insulation on a PV source circuit wire becomes damaged, and the current-carrying part of the conductor makes contact with a frame or rail,” said Brian Mehalic, PV Curriculum Developer and Instructor at Solar Energy International.

What are the bonding and grounding requirements for PV systems?

The specific bonding and grounding requirements for PV systems in Article 690 are in Part V. Section 690.41 covers system grounding, allowing both grounded and ungrounded PV array conductors.

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.
