Solar Street light working principle
Solar Street light uses solar energy (sunlight). Solar Street lights absorb solar energy during the daytime. The lights work on the principle of the photovoltaic cell or solar cell. The solar cells convert solar energy into electrical energy, which is stored in the battery. At the night time, the lamp starts and it consumes the electricity already stored in the battery. During the day time, the battery gets recharged and the process keeps on repeating every day. Solar panel is very important part of solar street lights. There are two types of panel in solar lights one is polycrystalline and second is monocrystalline. High effective solar street lights used LED lighting source. The rechargeable battery stores sun lights and turns into electricity. The controller is very important part of solar street lights to switch on and off charging and lights.
