This project is based on the idea of maintaining maximum utilization and minimum loss of available energy. The plenty of solar energy available during the day time is stored in a solar cell and the stored energy is used to glow the street lights during the whole night. Also, the system provides a power saving mode of operation by adapting the method of automation. A dark sensor and a light sensor provide 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 it will be turned “OFF” automatically if sufficient light is available in the surrounding. Again, the auto intensity control mechanism has been applied by the help of a microcontroller to control the light intensity of the luminaries as per the requirement. Hence the loss of energy due to unnecessary glow of the street lights can be avoided.
