This work deals with the efficiency analysis of two different aerodynamic profiles to compose the design of a vertical axis aerogenerator to be installed to supply the electrical demand of a residence in order to select the best model. The comparison was made using numerical methods, gathered in two free software, XFOIL and XRL5, used to make simulations with two NACA profiles, 0012 and 0018. The data obtained in the simulations were used in codes written in SciLab environment in order to calculate the generated powers with each profile and to draw their respective curves of operation. Obtaining this program and the curves generated by them is also the objective of this work. The equipment is designed to have the operation in conjunction with the electric network installed in the residence, thus reducing the energy consumption coming from the local company. The simulations converged to a more efficient profile, the operating curves were designed and the result obtained was a production superior to the one demanded in more than 40%, even considering some losses. With this it can be said that the use of this type of generation, in front of its cost, is feasible and very promising.
