Low speed operation can be had, but then high speed (high wind) is compromised. Remember that wind energy (wind power) is a function of the wind speed squared.

Variable pitch blades can adjust to different wind speeds, but then they introduce a lot of mechanical issues. I do recall someone using an old surplus blade hub from a turboprop aircraft engine and using it as a variable blade hub wind turbine.

Not a lot of geographical areas are favorable for wind and FAR more are better for solar PV. Just compare the maps. There are a few areas that overlap, but not many.

And solar PV can be put up by DIYers. Putting up a several hundred lb wind turbine on a 100+ foot tower is completely another issue!
