June 15, 2011 – NEMA (The National Electrical Manufacturers Association) has published ANSI C136.40-2011 American National Standard for Roadway and Area Lighting Equipment-Solar Lighting Systems. This new standard defines requirements for the specification and installation of dc solar-powered roadway and area lighting systems, and addresses topics such as light source requirements, batteries, internal labeling, and power controls. As municipalities look for ways to take advantage of solar-powered equipment, NEMA says the standard will provide valuable guidance for installations. CLICK HERE for details.
