Power Curves

Proven 2.5kW

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.

Features

• 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

Technical Specifications

11 mile per hour = 13.6 kph = 0.45 metre/second.
Annual Output 2 range is quoted to cover typical average wind speeds (annual).
  Lighter wind sites with typical 10 mph will produce lower end of range.
  Higher wind speed sites, e.g., 13.5 mph average will produce upper end of range.

All readings taken with an ATP SL-25 dBA meter at the base of the
  tower at a height of 5 ft.

*A car passing 65 ft away @ approximately 40 mph is 70-80 dBA.

Proven 6kW

The Proven 6 produces 6kW of electricity.  It is able to meet the power needs of a standard house with four to six bedrooms, excluding heating.  Any excess energy production can be stored or exported to the grid, depending on local regulations.

The Proven 6 is suited to a broad range of applications. It has been installed in schools, local authority buildings, agricultural small holdings, business and retail premises.

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.
