What I learned when I tried installing a wind turbine on my house

I'd be very interested in a tiny turbine that gives off 500W per hour to cover the basic power consumption of the house when there is no sun shining. But most stuff I see is junk, and the other stuff is way too powerful for what I need.

Good quality wind is high up.

Installing a turbine on a house is technically problematic (a mast is simpler to deal with), it is hard to maintain there and can convey noise into the house.

The advise about having a few acres of flat land as a minimum - it is sensible, unless other options beside wind cannot be chosen.
