Solar Lighting Manufacturer-SPARK. Solar street light SRL-SPL-72are new energy-saving products using 90W high power street lights as lights source, the working method of solar street lights is: solar panels absorb sunlight and convertthem to electricity to drive 90W LED street lights. The whole systerm is mainly composed by: 90W LED street lights, solar panels, lead-acid batteries and solar street lights controller, pole(suggest 6-8m height). Because of different weather conditions in different countries and different requirements from different markets, so the specificication of each part of the whole solar street lights system, especially solar panel and battery, are depending on following factors: Average local daily sunshine hours. Working times ofsolar street lightsper night. Backup days of the solar system during rainy days. The Advantage of Spark LED Solar Street Light1). Lower power consumption2). Higher power, Higher intensity Solar Powered Outdoor Lights3).Save all your electricity cost. Save electric transformer and cable cost.
