Renewable energy is all kind of energy produced from a natural source that not diminish because its utilization is "renewable" [1]. More and more renewable energy resources are used, because they offer multiple advantages such as the energy output facility in small scale and because they are entirely compatible with the environment. The renewable energy used in this project is the photovoltaic solar energy, obtained by the direct conversion of the solar energy in electric energy through the use of solar cells, that can be of several kinds, being the most common of silicon. The main advantage of photovoltaic system is the generation of clean electric energy, or either, generates energy without emitting pollutant and without destroying the environment, moreover is an inexhaustible source of energy. The main disadvantage is, nowadays, the high cost and its low efficiency, so to continue developing it is necessary establish capable mechanisms to make it possible. The search of these mechanisms of incentive becomes-itself a lot important, because the renewable energy and not conventional do not produce a financial return to the investor properly said, but brings lots of benefits to the community, the society and to the environment. This project has the purpose of create an electric energy generation system through solar photovoltaic modules to carry batteries of a motorized wheelchair. An electric wheelchair is moved by electric motors of direct current that are feed by batteries, permitting a medium autonomy of 10km by load. The batteries are recharged by a battery supplier. This operation should be carried out daily in a space of 6 to 8 hours.According to the Demographic Census realized in 2000 carried out by the IBGE, Brazil has around 1.416.060 physical deficient, which 861.196 are men and 554.864 are women. From a request of a user of electric wheelchair the idea of this project was shown up. The user complained that he stayed a long time carrying his seat and had short time to use it. The goal of this project is analyze the reliability, the efficiency and the costs to implement this system. The main purpose is the increase of the autonomy, the saving of electric energy and to give more freedom to the user. Renewable energy is all kind of energy produced from a natural source that not diminish because its utilization is "renewable" ^[1]. More and more renewable energy resources are used, because they offer multiple advantages such as the energy output facility in small scale and because they are entirely compatible with the environment.
