6 FAQs about [Photovoltaic panel bonding method]

Can PV panels be ground bonded?

Several years ago Wiley Electronics LLC developed a scheme that allows PV panels to be directly ground bonded to the aluminum rails or other mounting systems. The rails are then connected to each other and to ground. The products are marketed under the “WEEB” name. WEEB stands for "Washer, Electrical Equipment Bonding".

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.

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.

How do you bond a PV module to a metal frame?

A decade ago, it was common practice to bond the metal frames of PV modules by drilling and tapping a hole in the aluminum frame of each module, fastening a lay-in lug to each, and then connecting those lugs with a bare, stranded, copper conductor.

Why is grounding and bonding a PV system difficult?

A number of factors make the grounding and bonding of a PV system difficult. PV systems are exposed to the elements, which can result in atypical situations where the usual practices for bonding may not perform as intended.
