Sanyo and Panasonic recently announced the launch of the Everleds Lithium-ion Solar StreetLight that is designed to reduce impact on the environment. Thehigh-tech street light is made by combining solar cells and lithium-ionbatteries. The high efficiency solar cells harness solar energy andstore it in the lithium-ion batteries attached to the back of the panel.
Unlike previous solar streetlights that came with separatelyinstalled large lead batteries, the Lithium-ion Solar Street Light has a more refined design. It requires just a day’s charging and it is allready to illuminate for up to 15 hours every night. As it sports a slim, lead-free design, it is ideal for use in schools, parks, streets,around housing complexes and public outdoor facilities. The two versions of the street light are scheduled for release in Japan in January 2011.
