Our leading-edge Cleanfield V3.5 is a 3.5kW Vertical-Axis Wind Turbine (VAWT), and is designed to produce clean, reliable energy for residential and commercial applications. The system has the unprecedented ability to be mounted on flat rooftops, as well as traditional applications such as towers and poles. The Cleanfield V3.5 can be installed without the need to change existing wiring, and can be used for both grid-tie and off-grid applications (off-grid available late Spring 2008).
