Renewable energy resources exist in nature in a non fossil state. Sun radiation and wind are inexhaustible since they are both renewable. Installing photovoltaic systems connected to the network becomes economically interesting. Actual efficiency of photovoltaic cells is still fair. The production of energy can only be done during day time while the demand is maximal on night time. The wind energy is the electrical energy produced from the wind by an aerogenerator that uses the kinetic of wind. This energy is renewable and will not vanish soon. A DC converter is connected to the aerogenerator, it will be charging a group of batteries in order to store and produce electrical energy. The produced wind- power remains constant when the turbine speed varies but slightly goes down after a certain speed limit. Combining the two sources of renewable energy will lead to a maximum efficiency in electrical energy production. The system consists of a controller that will switch between the solar panel or the wind turbine. The one that produce the maximum power needed will be switched on.
