6 FAQs about [Grounding resistance standard of photovoltaic panels]

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.

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.

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.

What is a solar substation grounding guide?

Abstract: This guide is primarily concerned with the grounding system design for photovoltaic solar power plants that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80.

What is electrical & PV grounding?

Before discussing the subject of grounding, the term “grounding” requires definition. There are two types of grounding in electrical and PV systems—equipment grounding and system grounding. Equipment grounding is known in the ROW as safety grounding or protective earthing.

Does a photovoltaic system have a DC grounding system?

Photovoltaic systems having dc circuits and ac circuits with no direct connection between the dc grounded conductor and ac grounded conductor shall have a dc grounding system. The dc grounding system shall be bonded to the ac grounding system by one of the methods in (1), (2), or (3).
