Data on actual measured performance of small wind turbines at the Test Field for Small Wind Turbines in Zeeland, the Netherlands. The site has a very low average wind speed of only 3.8 m/s during the 2008 test period. The turbines, on the whole, performed poorly.

The Skystream uses a 3.72-meter diameter, three-blade, downwind rotor. Southwest Windpower claims that this rotor will deliver 1.8 kW at its rated speed of 9 m/s and generate 4,800 kWh per year at an average annual wind speed of 5.5 m/s (12.3 mph).

That's plus, we need a lot more operating turbines in the Greater Toronto Area. . . The French test site for small wind turbines has published a report on the performance of Southwest Windpower's Skystream 3.7 wind turbine. . .
