Guide to Small Wind Energy Systems

The size of a turbine and the speed of the wind determine how much elec-tricity (power) a wind energy system will produce. A small wind energy system has a power output as much as 100 kilowatts. A 100-kilowatt turbine operating in a suficiently windy loca-tion (on average 12MPH) can produce enough electricity over a year for 20 typical homes.

This is advantageous for various low speed applications since the efficiency at higher speed (~2500 rpm) reduces significantly (~45%). Typically, the output power of a vehicle alternator operating at 2500 rpm with 14 V DC is ~ 600 W. The power output achieved at 1000 rpm was found to be 150 W with maximum efficiency (~54%) at 1300 rpm [1, 8].
