Solar Panel Safety Labeling Requirements | DuraLabel
Learn solar panel safety labeling requirements that protect workers and support NEC compliance. See what labels are required for PV installations.
How to Properly Label a PV System per NEC 690 Part VI
The marking must be permanent, visible after installation, have capitalized letters of the minimum size specified, and contrast the background (commonly white letters on red).
Solar Signs
Solar system signs not only encourage workers to stay safe and caution them of hazards, but also provide additional information such as voltage amount and disconnect location.
690.31 (G) (3) & (4) Marking and Labeling Required.
The labels shall be reflective, and all letters shall be capitalized and shall be a minimum height of 9.5 mm (3⁄8 in.) in white on a red background. PV power circuit labels shall appear on every section of
PHOTOVOLTAIC SYSTEM SIGNAGE WORDING
Where photovoltaic systems are interconnected to battery systems, generator backup systems, or other secondary power systems, additional signage acceptable to the fire code official shall be required
Technical Bulletin: NYSERDA Solar Photovoltaic System
Current code allows for warning signs being red with white lettering or the ANSI & OSHA required orange with black lettering. Informational signage is yellow with black lettering.
