Everytime I look into the same thing, it's always that these dont have a great turndown to small single unit scale.
Where solar is quite modular, putting 1 or 2 of these turbines on a house, that are also not tall enough to get above all the wind blockers (other houses, trees), just won't make sense for a long time.
Looks like covering big box stores gets around several of those barriers, which is great.
