We have increased the blade diameter from 15 ft to 20 ft. This system is rated as a 50kW system. We have patented our designed and the automation of this 25ftx25ftx14ft wind turbine focused for rooftop mounting and standalone pole mounts for netmetering application. Financially for the end user the payback is three and a half years in several states and even faster in foriegn countries were the electric rates are much higher.

I was looking for the best low wind speed wind turbine. I was interred in that matter but along my experience, my conclusion are as follow - It make more sense for hydro than wind power - For wind energy it could make sense if the wind speed is mainly one direction or 2 direction and building could be used as wind increase shroud. - Other application, shroud weight and volume cause problem in high wind for yawing and structural tower design, which mean than something other than Class IV site is not recomended - This solution is not very use because of economic matter, increasing rotor blade is cheaper and easier to sustain high wind speed than shroud wind turbine.
