Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated in the pole itself. The photovoltaic panels charge a rechargeable battery, which powers a LED lamp during the night. Each street light can have its own photo voltaic panel, independent of other street lights. Alternately, a number of panels can be installed as a central power source on a separate location and supply power to a number of street lights Solar street lights are independent of the utility grid. Hence, the operation costs are minimized and require much less maintenance compared to conventional street lights. Separate parts of solar system can be easily carried to the remote areas
