The Proven 2.5 produces 2.5kW of electricity. This can meet the power needs of a standard three-bedroom home, excluding heating. Any excess energy production can be stored or exported to the grid, depending on local regulations. The turbine is approximately the same size as a standard telegraph pole.

The robust Proven 2.5 can be used to power small lighting systems in commercial premises. The Proven 2.5EX is widely used on off-shore oil platforms, as it is the only turbine in the world that is totally explosion-proof.

Grants and funding for installation are widely available for consumers and businesses. Generating electricity from a wind turbine helps to cut down CO2 emissions and reduces climate change levy charges.

Proven Patented Furling - In winds of above 25 mph, the Proven's blades twist to limit power in response to high rpm. In higher winds, the blades will begin to cone, reducing the rotor diameter, to maintain a constant rpm.

Marine Build Quality - All machines are manufactured with galvanized steel, stainless steel and plastic components.

Low Speed Equals Durability.
