Solar street light uses solar energy as an energy source. Solar Lighting can be used for urban parks, Highways, roads and lawn lighting.The photovoltaic panels charge a rechargeable battery, which powers a LED lamp during the night. Applications Solar street lights are independent of the utility grid. Hence, the operation costs are minimized. Solar street lights require much less maintenance compared to conventional street lights. Since external wires are eliminated, risk of accidents is minimized. This is a non polluting source of electricity. Separate parts of solar system can be easily carried to the remote areas.
