Rosslyn, Va.-based National Electrical Manufacturers Association (NEMA) has published ANSI C136.40-2011, "American National Standard for Roadway and Area Lighting Equipment—Solar Lighting Systems."

This new standard, produced by the ANSI Committee 136 for Roadway and Area Lighting, defines requirements for the specification and installation of DC solar-powered roadway and area lighting systems. Topics addressed include light source requirements, batteries, internal labeling, and power controls. As municipalities look for ways to take advantage of solar-powered equipment, this standard will provide valuable guidance for installations.
