Solar powered street lights are their own unit and used for public places like sidewalks, roads, and parking lots. They contain solar panels, batteries, LED lights, and controllers. Batteries are stored in the day, and at night, the stored energy is used to power the LED lights. Some products include adjustable motions and differ in how much light they conserve. Solar street lights save electric energy for towns and cities which makes them eco-friendly and requires low maintenance, making them useful for all places.
