All our wind turbine blade are designed by wind turbine expert and tested in wind tunnel. The blades have the advantage of: high power coefficient (over *5%), low start-up wind speed, good anti-fatigue capability, high strengh (meet stall requirements), high quality surface, low noise level (under *5dB), no tip run-out, good anti-corrosion capability (leading edge protection technology, provent the corrosion from sand, rain and salt), low wind resistance (roughness technical treating and protection layer on surface), good running performance and balance capability (blade chord is *0 degree with blade root; for blade from 0.5 to 5KW, weight difference is less than *0g in one set, less than **0g from sets to sets.
