The unique feature of the vehicle is being solar operated system, but it does not use battery to supply the motor, instead it uses capacitor banks there are four different capacitor banks used in this system, where there banks are switched one by one using the high frequency switching through the microcontroller. Many specifications must to know about solar car from solar array , motor, capacitor bank and so on each specification has theory and calculation to mate it function correctly & able to move perfectly. The most important things id\s the capacitor bank because before this there is no solar car driven by a capacitor bank. This project a lot depends on capacitor bank because it using influence if the solar car can drive or not. Using brain storming techniques to generate ideas , several initial design may be consider a common place to start is with the shape of the car since it will dictate the design of many other system initial designing concept are also developed for chassis design mechanical system design electric system design, driving train design& solar array design that show promise are investigated further so that design can be compare through trade of studies the concept must be eliminated until a final design can be agreed upon there are many factors to consider to each design.
