Jul 10, 2019· So, it can work as a major hub for information. These are some features of solar street lights which make it a better option over a traditional street light. We can confidently say that solar-powered lights will inevitably be the street lights of the future. And investing and installing in these will play a major part in a clean, green environment.
Outdoor solar lights use the energy provided by sunlight to charge preinstalled batteries. Most have sensors that will turn the light on automatically when the sun begins to go down and off when the sun comes up. Some solar lights are mounted on ground spikes or stakes, and others are simply placed on the ground.
