Solar Street Lights are raised light sources that are powered by photo voltaic panels generally mounted on the lighting structure or incorporated in the pole itself. The photovoltaic panels effectively charge a rechargeable battery that powers a fluorescent or LED lamp during the night. Most solar panels turn on and off automatically by identifying outdoor light by means of a light source. Solar Street Lights are projected to work throughout the night. Many can stay ignited for more than one night if the sun is not present for a couple of days.
Every street light can possess its own photo voltaic panel, independent of other street lights. Alternately, a number of panels can be installed as a dominant power source on a different location and stock power to a number of street lights.
