  • Too much money for this . Theres other turbines at half the cost for the same 4kw power. keep shoping this is not the best ofer. And no info at how it works nor do you get any pictures of the componets?

  • @prototype2020 We do encourage our customers to compare several turbines, and we believe ours is priced very competitively for its quality! Keep in mind this is the only small wind turbine in the U.S. with a certified power curve too, so you can rest assured it will perform as expected.

  • Thank you for your comments @HomeWindTurbines7 and @slickyb. To elaborate on the topic, vertical axis turbines have indeed been shown to operate very well under numerous conditions. In areas with turbulent winds, for instance, or locations where the wind changes directions often, VAWTs are better able to grasp the energy in the wind due to their omni-directionality. Our 4 kW turbine, seen above, operates at only 120 RPM, which allows it to operate with minimum vibration and noise production.

  • 30K is ridiculous for 4000watts. total ripoff.

  • Ok, its true that im not an engineer, but still don't understand what costs 30K in an electric generator, and a piece of carbon frame... btw Aluminium is MUCH cheaper, and light too! Why dont u use aluminium? I made a small counting, and i found that at us in Hungary it would take 16 years to come back it's price, if I switch to electric heating, AND IF it provides enough energy for the heating, and every electric devices!

  • In 2 months this will be on my house !! And fritopanpan... its $ 30,000...
