About Specifications and standards for photovoltaic panel grounding jumpers

3) It is recommended that the main bonding jumper (MBJ) and the grounding electrode conductor (GEC) are connected together at the same point (i.e. grounding bus-bar inside main disconnect or distribution panel of a residential or building facility).

This paper addresses the requirements for PV system grounding contained in the U.S. National Electrical Code ® (NEC ® ) published by the National Fire Protection Association (NFPA).

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.

rooftop PV systems to be installed according to the manufac-turer’s instructions, the National Electrical Code, and Underwriters Laboratories product safety standards [such as UL 1703 (PV modules) and UL 1741 (Inverters)], which are design requirements and testing specifications for PV-related equipment safety (see Equipment Standards below).5.

6 FAQs about [Specifications and standards 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)].

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 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.

What is a solar substation grounding guide?

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.

Does a PV array need a grounding conductor?

Since the PV array and other electrical equipment in PV system, e.g., inverters, are often located remotely from one another, 690.43 (B) requires that an equipment grounding conductor (EGC) be run from the array to other associated equipment.
