25kw Wind Turbines

25kW Wind Turbines Power Curve

A 25kW  wind turbine produces enough energy to power a small neighborhood. These devices are also intended for agricultural and light industrial applications. It has also been used for years in remote village applications, where diesel power systems supply electricity for a small grid.  Click on the thumbnail to the right to view the Power Curve chart
