Warnings : These calculations uses a mathematical idealization of wind speed distribution, The validity of this is improved if period measurement of wind speed is large.
This model will work better with annual or at least monthly average wind speed. Uses of this model with daily or weekly average wind speed is not recommended, because
on short period of time the wind doesn't follow a Weibull distribution.
In all cases it is important to understand that it is a simulation and that real performances may vary.
