Smart Energy solar streetlights are a flexible light system, which is autonomously supplied by PV (photovoltaic) Solar Energy. The streetlights come with 5 LED units, each consisting of 3 high power LED’s. The LED’s are sealed in an IP68 waterproof Aluminium housing which also acts as a heat sink. This innovative design guarantees the highest efficiency as well as outdoor usage. These PV Street Lights are assembled with 5 LED units, an 85Wp PV solar panel and 40 Ah solar battery. The charge controller has an automatic dust to dawn setting so that an automatic usage of the system is guaranteed. The lighting distribution diagram for the streetlights is provided for each project. The product is manufactured in Germany.
