15KW Proven turbines


Proven 15
Available from Spring 2007, our largest model will produce 15kW. The Proven 15 will supply a 6 – 10 bedroom house, with the potential to sell excess electricity back to the National Grid, or supply a group of smaller houses. The Proven 15 is also ideal for commercial applications such as agriculture, larger telecoms towers, small industrial units and mini wind farms.
