alternative energy generation

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.
