This project is a model of a car that runs on solar electricity, a renewable and non-polluting energy source. Photovoltaic cells convert sunlight into electricity and charge an electrical capacitor inside the car.
The photovoltaic cells are installed on the roof of a garage as they are unlikely to be placed directly on the car. Indeed, taking into account the efficiency of the best current cells, the roof surface of a car is not sufficient to provide enough electricity.
It is likely that some of the electricity produced by the solar photovoltaic cells will be sent back into the grid. The car will be recharged as needed, preferably at night when demand is low and power is cheap. In terms of the overall balance, the solar collectors will have produced a quantity of electricity equivalent to the energy needed by the car.
