Solar container system integrated grounding specification requirements

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.

Do PV systems need grounding?

It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. This article covers grounding in PV systems, which differs slightly from standard grounding systems.

What are the requirements for a solar PV system?

All metallic parts, equipment, and supporting structures in the PV system must be bonded and grounded. The EGC and GEC conductors used for AC and DC grounding must be sized and installed according to NEC 250.104, 250.122 (Table 250.122), 250.134, 250.136, and 250.66 (Table 250.66).

Does IEEE Std 80 apply to substation grounding?

The guide expands upon methodologies, concepts, and practices provided for substation grounding in IEEE Std 80 to apply to a larger SPP facility. This guide does not apply to substations used to interconnect the solar plant.

Does this guide cover small scale solar power plants?

Similarly, this guide does not directly cover small scale solar power plants (such as rooftop type systems), substation grounding, or lightning protection.
