6 FAQs about [Photovoltaic panel grounding detection standard]

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 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.

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.

How does a PV system detect a ground fault?

In PV systems that are equipment-earthed and protected with a system ground (as in most cases), a ground-fault condition is detected by current flow in the grounded conductor and electrode, which results in the circuit being opened and an ground-fault alarm being displayed on the inverter.

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.

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.
