Solar outdoor lighting systems use the light energy of the sun available during the day to provide lighting at night. Solar street lighting systems are used to provide illumination on the streets, warehouses, stadia, office premises, open areas, farm houses, hotels, hospitals, parking lots, industries and other general lighting applications.The Solar PV outdoor lighting system, a reliable and efficient stand-alone system, consists of a PV Module, a battery and a luminary with very high efficient electronics all mounted on one pole with necessary hardware and cables. Therefore, it offers several advantages.It is totally independent of regular power sources. There is no need to excavate to lay underground power cables, no long distance cables are required and therefore no transmission losses. Monthly electricity bills are cut drastically and you have the satisfaction of owning and running an environment friendly device.It is a totally independent of regular power sources. There is no need to excavate to lay underground power cables, no long distance cables are required and therefore no transmission losses. Monthly electricity bills are cut drastically and you have the satisfaction of owning and running an environment friendly device.The Solar panel absorbs sun rays and produces DC current.This power is stored in the battery. The luminary consists of the light source. A solar lighting system is capable of powering different kinds of light sources – CFL, Florescent tubes, LED etc.The pole used is fabricated with mild steel and galvanized. It has a structure to mount the solar panel on top and a battery box to store the battery. The light source is usually at the top of the pole.
