Gaia-Wind 11kW Wind Turbine
The Gaia-Wind 11kW is, in fact, capable of generating energy comparable if not greater
than some of the 20kW turbines on the market, due to its large swept area (rotor
diameter).
Suitable for supplying power to farms, offices and small companies, we also consider
the Gaia-Wind 11kW applicable in a greater number of situations and as such is a
key product in our sub-100kW market.
With 150 wind turbines already installed, Gaia-Wind has more than 1,000 years of
operational experience. It has received the Clear Skies accreditation under number
WT5038, making the turbine eligible for all grant schemes for small wind turbines.
The technical specification is detailed below and this is also available to download
as a PDF file.
