The Most Important Labels for Solar Electrical Systems

While there’s much to consider when installing a home solar system, warning labels and cautionary markers are things you should never overlook. Below, we explain why you need labels for your solar electrical system, what the most important labels are, and more.

Why You Need Labels for Your Solar System

When installing a solar electrical system, the system must have the necessary warning signs and labels. Solar systems, like any electrical system, can be dangerous if precautions aren’t taken for the occupants of the home and any electricians working on the system.

Along with the safety aspect, proper labeling also means workers can work more efficiently and consistently when conducting maintenance and repairs. Plus, solar inspections will fail the system and halt installation if the system does not have the necessary labels.

Where You Need Labels for Your Solar Electrical System

All the labels for solar electrical systems are critical, and what’s most important is knowing where they go on the system. Many components of a solar PV system can be dangerous to an individual if they’re not properly labeled with cautionary markers.

The main labels that inspectors will look for are on the critical components of the photovoltaic (PV) system, such as the following:

• Junction box and conduit raceways
• DC disconnects
• Inverters
• Production meter
• AC disconnects
• Main service panel

NEC 690 Labeling Requirements

Not only do owners need to have warning labels for these components, but they also must meet the NEC 690 labeling requirements. The National Electric Code (NEC) is the standard for safe wiring and equipment installation in the US.

NEC 690 outlines the requirements for the engineering and construction of solar PV systems, including the labeling requirements. Ensure all your solar system labels follow these requirements to comply with the NEC and pass inspection.
