6 FAQs about [Equipotential connection of photovoltaic panels]

What are equipotential bonding and grounding in a lightning protection system?

Equipotential bonding and grounding are important elements of a lightning protection system. Grounding and equipotential bonding systems are complex electrical systems with components from civil engineer-ing, mechanical engineering, high- and low-voltage power engineering, as well as control and communication technology.

What is equipotential bonding?

In low-voltage systems – besides ad-hering to the requirements for discon-nection – equipotential bonding and protective equipotential bonding in particular are fundamental protective measures against indirect contact. During operation and also in case of faults, electrical energy systems have an electromagnetic impact on the envi-ronment.

Should a module frame be included in the equipotential bonding?

ssary, each module frame must be included in the equipotential bonding!Equipotential bonding should ideally be installed in such a way that modules can be removed from the layout in the oten-tial bonding losing its function.Equipotential bonding & earthingIf points are conductively interconnected to v

Can photovoltaic modules be installed on a roof with a lightning conductor?

When photovoltaic modules are installed on a roof equipped with a lightning conductor, a direct link between the metallic parts of the modules and the existing conductor is necessary to avoid a building up connection risk. If the roof cladding is metallic, it should be connected with the equipotential conductor.

Do photovoltaic modules need to be ground connected?

All the building’s active metallic structures and modules should be ground connected. (same ground or seperate OK?) When photovoltaic modules are installed on a roof equipped with a lightning conductor, a direct link between the metallic parts of the modules and the existing conductor is necessary to avoid a building up connection risk.

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.
