The Solar Street Lighting System consists of a solar panel with Photo Voltaic (PV) cells that converts the solar energy into electrical energy. The resulting electrical energy is stored in a battery through a solar charge controller. LED Lighting fixture operates directly from the DC battery. Decorative pole, of any height and in a wide range according to aesthetic requirement, by itself can house the solar panel, luminaire, and the control gear box with battery.
The lifespan of the LED source is nearly 50,000 burning hours as against around 5000 to 10,000 hours of conventional sources such as metal halide/high pressure lamps and 50 times that of GLS (general lighting service) lamps. To obtain the same light output, the power consumption of LED luminaire is just one-tenth of what is required for a conventional GLS lamp.
Though the investment on the entire system is higher upfront, long-term benefits due to the energy saving, longer lifespan, lesser maintenance, social and environmental benefits, outweigh. The complete solar lighting system costs from around Rs.20,000 (with 3-watt LED) and goes up to Rs.2 lakh (with 80-watt LED).
