Abstract
Fossil Fuel is one of the main pillar of resources in current society. Seventy-four percent of the total global consumption depends on it, including coal, petroleum etc. Nevertheless, a great number of countries start to focus more on renewable energy due to the current severe contamination and low efficiency. Development is restrained by many factors, such as low efficiency of light conservation and large cost of system establishment. Moreover, the general public usually expects much more from solar energy applications. Applying to this market demand, the invention of energy-saving cars, which utilise solar energy has become a key resource direction. Through design of optimal angle modelling of silicon photocells, Drag Coefficient and MPPT (Maximum Power Point Tracking), a new solution of utilising highly efficient solar energy automobiles is obtained.
