The graph below compares the output of the wind turbines in our database with a maximum power output between 450W and 900W. The Lakota has the quickest kick-in wind speed (2.7m/s) but the Navitron is the best performer in lower wind speeds (2-8m/s). In more blustery conditions the Lakota, Ampair 600 and Whisper 100 turbines produce similar power outputs, but the Lakota produces the most output at a given wind speed as of 14m/s.

The data shown here is drawn from the power curves as published by the respective manufacturers. Some of these are calculated in different ways. When the MCS standards, are launched (hopefully soon) we will have a fairer way of comparing the power curves of wind turbines. The outputs shown towards the right of the graph represent what you would get in gale force wind speeds, so look towards the left to get an idea of the instantaneous power outputs you might get at your site. This graph can't be used to predict actual annual outputs, since many other local factors will affect the performance of a turbine. Reliability and installed cost should be a major consideration.
