Mislabeling components in your PV system is a common mistake. Incorrect labels can lead to confusion during maintenance, troubleshooting, and emergencies. For example, if an inverter is mislabeled as a combiner box, it could lead to improper handling and increased risk of electrical hazards.
The NEC690 Building Inspector’s Guide is a set of reference materials developed for Building Inspectors and AHJ Officials as it relates to Article 690, of the National Electrical Code (NEC 2014) for Photovoltaic Warning Labels. The Guide also covers ANSI Z535.4-2011, the standard for the development of Product Safety Signs and Labels, which .
Mislabeled panels sounds likely, especially if there isn't another panel that is showing a response to the vent pipe shade. You probably won't see much of a ramp, individual panels report at random times, and can go 15 min or more without updating.
This guide is an essential resource for improving the safety of photovoltaic systems by ensuring compliance with the latest solar labeling requirements. Learn how to meet NEC standards, understand which solar components require labels, and discover effective labeling solutions for solar equipment to keep your facility safe and compliant.

6 FAQs about [What to do if photovoltaic panels are seriously mislabeled]
Do PV systems need labels and warning signs?
Installers should consult the National Electricians Code (NEC) regarding PV systems and any local regulations from cities and municipalities. The basic parts of a PV system that need labels and warning signs include the following: Now that we know what needs labeling, we’ll explore the PV labeling requirements that installers need to know.
Why do you need a solar PV label?
Labels and signage can warn workers of these dangers and encourage them to protect themselves. They’re also crucial for maintenance and repairs of the solar PV system after installation. Maintenance and repair workers rely on up-to-date and accurate labels to ensure their safety and help them work efficiently.
How to manage excess photovoltaic production?
As the below video suggests, a combination of the four possible options—grid injection, power limitation, storage, and the very attractive alternative of load shifting—frequently turns out to be the best way to manage excess photovoltaic production.
Why are labeling requirements important for PV systems?
Before we get into the labeling requirements for PV systems, it’s worth noting why these labels are important for installers and owners of PV systems. There’s always the danger of short circuits, arc flashes, and fires to installers and anyone nearby if they’re not careful.
How often does excess photovoltaic production occur?
Therefore, excess photovoltaic production happens relatively often, even when the photovoltaic system is sized so that it does not exceed the building baseload consumption. Alternatives for managing excess solar production
Do solar panels go to landfill?
Unfortunately there’s a catch. The replacement rate of solar panels is faster than expected and given the current very high recycling costs, there’s a real danger that all used panels will go straight to landfill (along with equally hard-to-recycle wind turbines).
