About PV Labels NEC-Compliant Solar Labels Built for Real Installations PV Labels specializes in high-quality solar warning labels , photovoltaic labels , and electrical safety labels designed to meet current National Electrical Code (NEC) requirements. Our products are built for contractors, electricians, and solar installers who need reliable labeling solutions that help systems pass inspection the first time. Designed to align with current NEC and IFC requirements to help reduce inspection issues and unnecessary rework. Produced using UV-based, flood-coat screen-print inks for strong visibility, sharp color, and long-term outdoor durability. Made with premium outdoor-rated materials engineered to resist fading, peeling, and breakdown in harsh field conditions. When it comes to outdoor solar and electrical installations, standard digital printing does not offer the same long-term performance. Direct sunlight, weather exposure, and abrasion can quickly reduce legibility and shorten service life. That is why our signs and labels are screen printed.
