AW 500kW Wind Turbine - 47m rotor
Need a turbine to maximize a FIT program in your country?
In an age of King-sized wind turbines designed for wide open spaces or off shore, Aeronautica Windpower is proud to introduce a 500 kW turbine specifically aimed at countries or local governments favoring distributed generated wind power incentivized to be capped at a specific nameplate level for maximum Returns On Investment (ROI). The AW 500 is perfect turbine for your application.
Aeronautica takes great pride in manufacturing a quality product that is designed to last the test of time. In addition, being American made, Aeronautica is able to provide financing options to aid your projects construction/manufacturing costs, financing guarantees and insurance products backed by the US government.
Aeronautica 750kW wind turbines are built according to strict IEC 61400 guidelines in our ISO 9001 rated factory to insure the highest degree of quality for a long service life. The Internet-ready SCADA system provides remote access and viewing from remote locations. Our time-tested gearbox isolation system absorbs shocks with ease, adding to long term durability. These turbines are ultra-quiet and highly transportable to reach areas otherwise inaccessible to larger machines.
With its low profile, ultra-low noise signature, and highly efficient output, our 500's provide the perfect balance between economic output and acceptable size. Backed by our licensor, Norwin A/S, Aeronautica is poised to help your project reach its maximum potential.
