HellermannTyton Pre-Printed Solar Installation Labels are designed to meet the requirements of the National Electrical Code and the International Fire Code as well as being acceptable to the Authority Having Jurisdiction (AHJ). Labels are made with durable UV-stable materials and adhesives that are designed to stick to both baked enamel and powder coat surfaces. Where applicable, labels are made using reflective materials for first responder safety. Some pre-printed labels are printable using a thermal transfer printer when variable voltage or series data must be printed and displayed.

If there is one thing that every installer, engineer and designer can agree on is that there is no universal consensus on the definition of acceptable photovoltaic infrastructure labeling. The industry is still new and the codes and regulations are so diverse that most installers are left on their own to figure out how to ensure they pass inspection, while still meeting the labeling requirements of the National Electrical Code (NEC) and the International Fire Code (IFC). Both standards go hand in hand and address key issues of PV labeling. All Fire Marshalls are concerned about safety of first responders and emergency personnel.

Again, there is no right or wrong answer on marker selection as long as the installer is meeting the requirements of the AHJ (Authority Having Jurisdiction) in all instances. The trend that we are seeing is that labeling products with specialized features, such as reflectivity, are the vanguard of the new era.
