One of the most well known and reliable brands of small wind turbines in North America. The Bergey family of Mike and his father Carl started the company in the 1970s.

Carl Bergey was an aircraft designer. Mike studied engineering at the University of Oklahoma.

Interestingly, before Mike joined his father manufacturing a small upwind, direct-drive wind turbine, he experimented with a giromill, a form of Vertical Axis Wind Turbine.

Their first turbine used solid-aluminum blades. These were shortly replaced with the pultruded blades they have made famous.

For many years they offered an 850 watt model, a 1.5 kW version, and their 7-meter Excel. The larger turbine was introduced in the late 1970s.
