Windterra Systems Inc. is a company dedicated to creating sustainable solutions to the environmental and economic challenges presented by the growing global demand for energy. Windterra is involved in the engineering, design and manufacture of roof-mounted small-wind turbine systems that give homeowners and other small-application users the ability to generate their own safe, inexpensive, emissions-free power by harnessing an abundant, renewable and freely available energy source.
Windterra’s Vertical Axis Wind Turbine (VAWT) is designed to operate in micro-winds as low as 3 metres/second (10.8 km/h, 6.7 mph) and can withstand winds as strong as 53 m/s (190 km/h, 118 mph). The optimal output of 1 kW is reached in wind speeds of 11-12 m/s (39 - 43 km/h, 24.6 - 26.8 mph). Windterra’s VAWT technology employs a unique airbrake system designed to engage when the unit rotates beyond the desired 225 RPM without creating additional noise
Incorporated in 2003, Windterra maintains an engineering development and testing site in Kelowna, British Columbia; its sales and executive offices are located in Calgary, Alberta.
