Abstract
The extensive access to solar and wind resources make them excellent members of the energy matrix for small consumer units. In order to decentralize the power generation, wind turbines and photovoltaic panels are being gradually incorporated into homes. Given this scenario, this work aimed to create a hybrid electric generator (wind and solar) to complement small power grids. Soon, a prototype was constructed, composed by a Savonius turbine with photovoltaic cells inserted on top of the propellers. The connection of the energy produced by the wind and solar systems was made with the use of diodes, to avoid a return of the electric current. After the construction, the prototype was submitted to tests to evaluate its performance. The temperature drop of the photovoltaic cells occurred as expected due to the rotation of the propellers. The wind generator produced little energy at low speed, identifying the need for a speed multiplier. Finally, interference occurred between the waves emitted by the wind turbine and the photovoltaic system, resulting in power loss of the dynamo.
