Gaia 133 11kW Wind Turbine
The Gaia 133 is easily recognisable due to it’s unique dual blade design. The turbine features an over sized rotor with a 133m2 swept area, allowing for extremely efficient energy generation.
The second main feature of the Gaia 133 is its exceptionally quiet operation. Noise is generated by small movement as the blade tips of a wind turbine cut through the air, with the noise level increasing if the rotors turn faster. The Gaia has three measures in place to reduce this noise level as much as possible: one less tip than traditioal triple-bladed models, tips designed not to feather or furl in the wind, and a fixed rotor speed.
The Gaia originated from a Danish design and carries a reputation for reliability. This smaller yield turbine model is popular with UK farmers.
Power Production
The Gaia 133 is rated at 11kW with an expected Reference Annual Energy (RAE) production of 27,502 kW at an average wind speed of 5 m/s.
The Gaia is particularly efficient for it’s size because it features a very large swept area. The larger blades also allow the turbine to begin producing power at the relatively low cut-in wind speed of 3.5 m/s.
