Solar energy is rapidly gaining notoriety as an important means of expanding renewable energy resources. As such, it is vital that those in engineering fields understand the technologies associated with this area. Its energy is both clean and free of cost. So maximizing the use of solar energy help to take the load off from fossil fuels like petrol, diesel, etc. and limit the emission of carbon dioxide hence preventing the pollution. Our project will include the design and construction of an Arduino-based solar panel tracking system to control the auto intensity of the street lights systems. Solar tracking allows more energy to be produced because the solar array is able to remain aligned to the sun and therefore it will provide the maximum output power used in lightning the street lights at night. The project is also designed to detect vehicle movement on highwaysto switch ON only a block of street lights ahead of it (vehicle), And toswitch OFF the trailing lights to save energy. During night all the lights on the highway remain ON for the vehicles, but lots of energy is wasted when there is no vehicle movement. This proposed system provides a solution for energy saving. This is achieved by sensing an approaching vehicle and then switches ON a block of street lights ahead of the vehicle. As the vehicle passes by, the trailing lights switch OFF automatically. Thus, wesave a lotof energy. So when there are no vehicles on the highway, then all the lights remain OFF.
