The growing energy demand coupled with the possibility of reduced supply of conventional fuels, evidenced by petroleum crisis, along with growing concerns about environmental conservations, research and development of alternative energy sources that are cleaner, renewable and produce little environmental impact. Among the alternative sources the electrical energy from PV is useful, since it is free, abundant, clean, distributed the Earth and participates as a primary factor of all other processes of energy production on Earth. A great advantage of photovoltaic is the reduction of carbon dioxide emissions. Despite all the advantages presented by the generation of PVs, the efficiency of energy conversion is currently low and thus it becomes necessary to use techniques to extract the ,maximum power have been proposed. Therefore this paper aims to extract the maximum power by using MPPT techniques.
