Just because they are spinning does not mean that they are generating power! Buyer's beware!  Knowing the exact cut-it speed of a horizontal axis wind turbine is one of the most crucial terms to understand when purchasing a wind turbine. The cut-in speed is the wind speed required for a particular wind turbine to begin to generate electric power.    The start-up speed is the wind speed at which the wind turbine blades will begin to rotate.  The cut-in speed is always greater than the start-up Read More »
