    Conventional means of transportation have a significant impact on people's lives, which depend on the current model to perform their routine activities. Families can expend up to 20% of their income on transport. On the other hand, internal combustion vehicles emit gases that impair nature, have low efficiency reaching a maximum 30% yield. In contrast, the electric vehicle has up to 90% efficiency and does not emit harmful gases directly. These factors contribute to the increase of financial and energy waste. This study aims to contribute to minimizing these impacts through analysis of an electric propulsion system of low cost, powered by photovoltaic source to be installed in a vehicle structure of PVC (Polyvinyl Chloride). The use of this renewable energy source enables the implementation of a photovoltaic power generation system, stored in lead acid batteries used in most of vehicles. After analysis of decision matrix, it was determined the most appropriate model that supports the proposal economically and evaluated electric DC motors found in conventional vehicles. These it was found that the engine of the windshield wipers can be used in vehicle propulsion system. To control the entire electrical system was used PIC micro controller, responsible for driving the motors through H bridge, consisting of MOSFET transistors. The simulation of this control system was held at the Proteus®.
