This set of wind generator blades is made of fiberglass and applicable for up to 2000W wind turbines. Hub and nose cone are included for free. The shipping cost is for USA 48 states only. The customers from other locations need to ask the shipping cost before placing order.

Note: Please be careful comparing our blades to our competitor's blades. Their blades are poorly made with thick seam lines that severely change the aerodynamic characteristics and cause a lot of noise. Also, our blades are shipped to us pre-balanced and in matched sets in their own boxes. Our competition receives their blades in a large crate with all the blades thrown in, causing scratches and cracks - making them appear to beused. You will be very happy with the blades we send you.

Designed and made to pick up the wind power as much as possible. The efficiency is graded as 0.49 in converting wind power to the mechanical power, which is at the very top end ( the highest is 0.5). The exact same blades are widely used in commercial wind generators. The performance of the blades is much better than home brewed ones.
