Proven Energy's 11 is the most popular unit in Alaska. This 6kW Wind Turbine will provide 3 times more power than a 2.5kW wind turbine and therefore is better suited for a larger house or to someone who wants to generate an excess of electricity for exporting on to the grid through net metering.
The Proven 11 supplied eight of their Proven 6kW wind turbines for Belgium's Princess Elisabeth research station in the Antarctic. The research station is the first zero emission facility in Antarctica and is used by scientists studying the impact of climate change
With incredible average wind speeds of 53mph and gusts of up to 200mph recorded it was previously felt that no wind turbine would be robust enough to survive such harsh conditions. However, Proven 6 wind turbines have demonstrated their amazing resilience generating electricity in 150mph winds on the Shetland Islands and in hurricanes in Japan. They also have coped with the extreme cold with temperatures down to -60 degrees Celcius which is common during the dark winter months in Antarctica.
Alaskan Wind Industries also has installed many Proven Energy wind turbines throughout the state of Alaska including a Proven 6kW that will be installed in Port Moller spring 2011. These wind turbines have proven to be the most reliable and robust wind turbine on the market today for Alaska and keeps producing! To see some of the production from these great units, please visit our Proven Addicts website, where owners have posted their production and discussions about these great units in Alaska.
Proven Energy has designed and patented the flexible blade system which enables the wind turbine to generate power in light or strong heavy winds up and over 156mph .
- 8 Proven 6kW's have been tested in Antarctica
- Safety cord through blade and attached to hub for more safety
- Permanent Magnet design for simplicity
- Keeps producing energy in high winds up to 156mph
