6 FAQs about [Photovoltaic bracket grounding welding requirements]

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 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.

Why is proper grounding important for a photovoltaic power system?

Proper grounding of a photovoltaic (PV) power system is critical to helping ensure electrical safety during its lifetime. PV equipment needs to be properly bonded, in addition to code-compliant grounding, so that the low current flows on metal parts can facilitate the operation of over current and ground-fault protection devices.

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 solar hot water system need a grounding system?

Section 690.43 of the NEC requires that PV systems have equipment grounding systems when there are any exposed metal or conductive surfaces that may become energized. This requirement applies to PV systems operating at any voltage, including small standalone 12-volt PV systems and even a 6-volt, PV-powered water pump on a solar hot water 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.
