A new label was added to identify PV equipment floating on – or attached to structures floating on – bodies of water. Per the code revision, this equipment must be identified as being suitable for the purpose and shall utilize wiring methods that allow for any expected movement of the equipment. white paper edition
The marking language requirements in the Fire Code, NFPA 1 11.12.2.1.1.2, and the NEC were different, making it unnecessarily difficult for enforcement and inspections agencies to align. Removing specific color requirements now allows local enforcement agencies more latitude.
Always check local codes before defining labeling formats. Todd Fries is a product category manager of identification systems with HellermannTyton North America in Milwaukee, Wisconsin. He also serves on Code-Making Panel 4 of the NEC 2023 and is involved with the changes and additions discussed in this article.
(2) Identification: PV system dc circuit conductors shall be identified at all termination, connection, and splice points by color coding, marking tape, tagging, or other approved means in accordance with 690.31(B)(2)(a) and (b). Exception: Where the identification of the conductors is evident by spacing or arrangement, further

This white paper discusses the changes and additions that impact labeling in many sections of the code related to PV and wind. As these systems grow and evolve, the required labeling continues to evolve
Failure to comply can result in failed inspections, costly rework, and most importantly, a dangerous environment for anyone interacting with the system. The core requirements for marking solar
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.
The materials found in this section may be used to establish recommended local requirements for Installers and Designers, and can serve to validate the use of high performance adhesive labels,
Labeling mistakes can lead to safety hazards, installation errors, and regulatory compliance issues. We''ll explain the most common mistakes in solar labeling compliance so solar
When the sun is shining, dangerous DC voltage is still being generated in the PV panels. The only way to eliminate this is to cover all panels with an opaque tarp.
You should have your solar panels lab-tested to prove they comply with the requirements and are safe to use. Some regulations, such as 47 CFR Part 15, mandate product testing, while other
What happens if my solar panel labels are not compliant? Non-compliant labels can lead to a failed inspection, causing project delays and additional costs for re-labeling and re-inspection.
The 2026 NEC brings new labeling requirements for solar installations. This solar energy news helps installers, developers, and stakeholders prepare for compliance.
