Collecting of clean wind energy is a very actual problem in our modern world of a global warming. The most popular construction of a wind energy station uses horizontal rotor and its axis must be fixed in some certain position during work process. As better by angle we fix the rotor, as more energy will be collected, so the problem of rotor’s rotation angle choice can be considered significant and very actual. In this work is proposed to use the polar coordinate cardioid dependence to approximate the real rose of the wind corresponding to a certain location. Symmetry axis of such cardioid will indicate the most efficient rotor’s position. For approximation is used least squares method and automated solving of non-linear algebraic equation. Developed technique allows choosing rotor’s rotation angle more reasonable, based on wind statistics of certain locality.
