Full mounting sets called "tower kits" are available.Ī range of synthetic materials including carbon fiber reinforced polymers, nanocomposites, and E-glass-polyester are available. Ground mounted small wind turbines are typically supported by four guy-wire, and a gin pole used to raise and lower the tower. To optimize efficiency, the tip speed ratio (the ratio of blade tip speed to wind speed) and lift-to-drag ratio should be kept at optimal levels. Most small wind turbines are horizontal-axis wind turbines, but vertical axis wind turbines (VAWTs) may have benefits in maintenance and placement, although they are less efficient at converting wind to electricity. Turbine blades for small-scale wind turbines are typically 1.5 to 3.5 metres (4 ft 11 in – 11 ft 6 in) in diameter and produce 0.5-10 kW at their optimal wind speed. The Canadian Wind Energy Association considers small wind turbines to be up to 300 kW, while the IEC 61400 standard defines them as having a rotor area smaller than 200 m 2 and generating voltage below 1000 Va.c.
They usually produce between 500 W and 10 kW, with some as small as 50 W.

They use a direct drive generator and use a tail fin to point into the wind, whereas larger turbines have geared powertrains that are actively pointed into the wind. Small wind turbines often have passive yaw systems as opposed to active ones. These turbines are typically smaller than those found in wind farms. Small wind turbines, also known as micro wind turbines, generate electricity for small-scale use.
