Proven Energy Wind Turbines

Proven Energy got its start in Scotland in 1982 with the first installation of a functioning turbine.

They currently claim to have manufactured and installed over 1,500 turbines. A prominent claim by Proven is the ability of their turbines to operate reliably in harsh climates. We would not deny them this proclamation.

They currently have several turbines operating in the frigid winds of the Princess Elisabeth Antarctic research station and others in the hot sands of Saudi Arabia. This is certainly a good set of extremes. If they hold up in these two places, that is probably a good indication that they have met the goal of being robust in diverse climates.

Being a downwind turbine, Proven Energy uses a design where the blades can bend and flex. In high wind, this allows the rotor to effectively shed the wind for speed control. Additionally this technique takes some stress off of the tower during gusty conditions but it is possibly at the expense of added fatigue on the blades themselves. It is advertised as the patented Proven Flexible Blade System.

All Proven turbines (except for the Proven 600) also use a manual braking system to stop the rotor. It is essentially a disc brake that can be engaged from the ground. This is a very desirable and reliable method for stopping the rotor.

The turbines are advertised as having “marine quality build” using galvanized, stainless steel and plastic components. Some other manufacturers offer marine grade at additional costs. There is one other fact about the Proven that most of us will not have to worry about, they are listed as being explosion proof.

The range of products is wide enough to please most home or small business owners. The turbines are available with rotor diameters of 8.4 feet, 11.5 feet, 18 feet and 29.5 feet.

Note

The information provided for this wind turbine(s) is very limited. We have only posted basic specs and information here. The "Turbine Reviews" section in "The Ultimate Consumer's Guide To Wind Power" is not comprised of these exact pages. The ebook does contain thorough, in-depth content, side-by-side comparisons, and our unbiased opinion of each turbine.
