Graphic Products Creates Solar Photovoltaic (PV) Labeling Guide

By Sally Murdoch

Solar Photovoltaic (PV) Labeling Guide

In 2016, solar installations in the U.S. hit the one million mark, and by 2018, the Solar Energy Industries Association (SEIA) forecasts that installations will have swelled over the two million mark. With the number of solar installations rapidly rising, consistent and accurate safety labels are essential to communicate the hazards that vendors, contractors, and emergency responders face. Graphic Products, a leader in visual communication, is making solar installations safer by offering a new online Solar Photovoltaic (PV) Labeling Guide. This new solar labeling guide is complimentary and instantly downloadable.

Labels for Many Solar PV Applications

Graphic Products’ new guide takes users through a brief history of solar power, then guides readers through different regulations on solar labeling for a variety of applications, including:

  • Inverters
  • Motor generators
  • PV modules
  • PV panels
  • AC modules
  • DC combiners
  • DC-to-DC converters

Although it’s freshly published in February 2017, users of the guide are already finding it valuable. Troy Haught, a Project Manager at Rosendin Electric in La Palma, California had this to say about the guide:  "Could not ask for more! This guide is a very useful tool for the project staff to reference during the design and construction phase of each project,” he said.  "Clean and uniform labeling is as important as the installation of the material itself, and this guide will help maintain our company standards across every project."

Changes to Solar Labeling in 2017

New regulations for solar labeling are in effect for 2017, and solar installers need to understand and include critical information on labels for PV generation systems. The 2017 revision of the National Electrical Code (NEC) has streamlined solar labeling requirements in an effort to improve compliance and safety. This guide goes through these specific changes, too.

Solar labeling is especially important for firefighters who must identify hazards, installation type, and emergency shutoff location during an emergency. In response, NEC 2017 closely aligns with the 2015 International Fire Code (IFC), specifying label format, size, location, and content, so firefighters can quickly identify the information they need to stay safe when responding to an emergency.

Types of Installations Needing Solar PV Labels

In this guide, installers working with interconnected power systems, standalone PV systems, back-fed overcurrent protection devices, circuit conductors, and many more systems will have labeling text, color and size requirements illustrated for quick reference. It also covers proper materials for solar labels.

With DuraLabel printers and supplies, users have the flexibility to create labels not only compliant with NEC’s requirements but also with codes specific to each state and municipality. DuraLabel printers can create labels and signs from ½" up to 9".

Could not ask for more! This guide is a very useful tool for the project staff to reference during the design and construction phase of each project.
