Remotely Control Automatic Street Lighting System Using Solar Tracking System

In our country most of the energy get wasted in street lighting i. e. unnecessary lighting of the street lamps continuously. To avoid this condition we proposed remotely control automatic street lighting system. The proposed system in this project uses combination of sensors, zigbee, solar inverter and solar tracking system. Use of LED lamps and solar tracking system together increases energy efficiency of the system by 50 to 60 %. Zigbee transmitter and receiver transfers all the information of the system to base station so that proper action can be taken in case of failure, Thus Automatic fault detection feature is achieved which ultimately reduces the maintenance of the system. The system is also characterized with auto switching feature between power sources that is, if voltage of solar powered battery falls below system threshold voltage level then it automatically switches to ac supply.
