Design and fabrication of a solar powered toy car

At present, solar vehicle is used as one of the cardinal energy saving vehicle where the application of renewable energy meets sustainable energy demand with reduction of fuel cost plus purification of atmosphere. In this vehicle, solar energy powers all or part of a vehicle´s propulsion. For running a model car or toy car which is a miniature representation of an automobile, electric power is needed to run the car. As there lies shortage of electric power in Southeast Asian country, it has become a vital issue to initiate the use of renewable energy in developing countries like Bangladesh for reducing the demand of electricity. This paper deals with an attempt to investigate the energy recovery possibilities from the solar energy by using a solar panel which converts light energy from the sun into electrical power. That power is transmitted to the storage battery. The stored power of battery is used to run the car. Speed to weight ratio of toy car illustrates comparatively more flexible and simple than any other design when load is varying. Aerodynamic drag, weight, and rolling resistance all influence the car´s design. Due to its simplicity and less bulkiness this design also reflects cost effectiveness and user friendliness.
