How much power does a renewable installation produce?

The Skystream 3.7 wind turbine that Heartland helped install at Greenbush has a rated output of 1.8 kilowatts. Because this part of Kansas is considered Class 2 with average wind speeds of 12 to 14 mph, that turbine averages about 300 kilowatt-hours per month.

A 5 kilowatt PV solar array will generate between 300 and 700 kilowatt-hours each month in this part of Kansas. Solar and wind systems will have high months and low months and predicting those will be important to a successful installation. The PVWatts Calculator from the National Renewable Energy Laboratory can help you find out how much power a PV solar array will generate at your location.
