Proven Engineering Products is a family owned business based in Stewarton Scotland, which manufactures and installs wind, hydro and solar energy systems. Established in 1980 with expertise in mechanical, electrical and control engineering, Proven has been manufacturing renewable energy machinery since 1991. Proven manufactures four models, including the 0.6KW WT600, the 2.5KW WT2500, the 6KW WT6000 and the new 15KW WT15000. All of these models share a rugged design and Proven's signature downwind blade configuration. Instead of pointing into the wind by using a tail, these turbines point away from the wind and have no tail. Because of the harsh conditions on the coast of Scotland, all of the Proven turbines are engineered for extreme wind and marine site operations. Overspeed protection is provided by the Proven Flexible Blade System. This uses special hinges on the blades that regulate their pitch in strong winds and "cone" the blades (bend them away from the wind) in extreme winds to keep the rpm of the turbine within proper operating tolerances. The major benefit to this approach is that the Proven turbines are able to maintain close to maximum output in high winds. Other turbines use furling systems which reduce the turbine output above a certain wind speed.
