Every wind turbine is different, despite seemingly similar power ratings. Some machines are designed to operate more efficiently at lower wind speeds, while others are intended for more robust wind regimes. A prospective wind power developer would be wise to investigate all of the various considerations and compare the projected performance to existing machines. Moreover, anecdotal information and even the professional services of wind power developers may prove helpful.
