Abstract: Harvesting energy from the environment responsibly is important. Conventional sources are depleting now a days so we are turning towards usage of renewable sources for various electrical applications. One of those most applications is lightening the streetlights. Hence our concept is to mimic the natural tree replacing the leaves as solar panels in all possible directions, electric power generated from those panels are fed into streetlights. Also, the system provides a power-saving mode of operation by adapting the method of automation. A dark sensor and a light sensor provides the automatic “ON”/”OFF” facility to the street lights so that it will glow automatically when it is required(i.e. when the surrounding will be dark) and will be turned “OFF” automatically if sufficient light is available in the surrounding.

Keywords: Solar energy, Street Light, Light Sensing, Solar Panel, LDR (Light Dependent Resistor), IR (infra-red) sensors.
