Solar Dusk Dawn System

Solar Dusk Dawn System

Our Solar Dusk Dawn System is an energy saving device used for automatic switching of street lights making proper use of grid power and increasing the life of the lamps by operating the street lights from sunset to sunrise. The Solar Photovoltaic (SPV) Dusk Dawn System is highly reliable and efficient for years of continuous flawless operation. A system can support BS many as 500 lamps depending upon the lamp characteristic. The operation is based on sensing the ambient light level which actuates the electronic controller to switch ON the street lights in the evening and switch them OFF in the morning. The sensor is hermetically sealed weatherproof and maintenance free, thereby ensuring reliability even in adverse atmospheric conditions.

The system has the inherent advantage of automatic setting of switching timings irrespective of whether it is winter or summer thus making it a totally unmanned operation. Once set for a particular light level, it remains unchanged through out the year.
