Guidelines for Designing Grounding Systems for
In this blog post, we summarize key points according to the NEC. The NEC is the primary guiding document for the safe designing
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.
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.
When it comes to grounding requirements for solar panels, you must meet the stringent guidelines that are central to your project. Failure to secure a solar panel grounding system not only creates potential safety issues, but can result in additional expense, penalties and rework.
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.
