6 FAQs about [Photovoltaic support grounding construction area]
What are the challenges of PV grounding design?
One of the challenges in designing the grounding for a Utility Scale Photovoltaic Power Plant is understanding how the system is actually connected, as there are different configurations. In many such systems, the grounding system is common from the DC grounding conductors and the AC grounding conductors.
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 the purpose of the grounding system design guide?
Scope: This guide is primarily concerned with the grounding system design for ground-mount photovoltaic (PV) solar power plants (SPPs) 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.
Where should a grounded PV system conductor be grounded?
The location where grounded PV system conductors must be grounded is covered in 690.42. It states that a grounded PV array must be grounded at the ground-fault protection device—and at no other location.
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.
Does grounding a PV array make a system less susceptible to lightning?
The First Revision of the 2017 NEC places this requirement in positive language, rather than as an exception. The informational note in 690.42 states that grounding a PV array close to the PV array makes the system less susceptible to lightning. This note is not always true and has been eliminated from the 2017 First Revision language.
