Product Portfolio
Turbines
- Bergey wind turbines are available in two sizes, a 10 kW unit primarily used for reducing utility bills and a 1 kW primarily used for off-grid applications. Both models have been installed in thousands of sites around the world and are market leaders in performance and reliability. If you are looking for a wind turbine for your home the Bergey Excel-S is the model for you.
Bergey XL.1
- With a rotor diameter of 2.5 meters (8.2 ft) and a peak
output of approximately 1,300 watts the XL.1 is intended for the off-grid
home market in the U.S., telecommunication sites, and for rural
electrification programs in developing countries. It is also a perfect
upgrade system for current owners of solar-only off-grid systems.
Very quiet operation is achieved with advanced rotor design and an oversized alternator that reduces the rotor operating speed.- Off grid sites
