I spent 5 years working in wind microgeneration (but with helical turbines) and entirely agree. Rooftop solar works because it's cheap and simple to set up. Wind is not that. The structural and installation requirements result in relatively high fixed costs. To offset that you need to scale the size of the turbine, and maximise the time they spend spinning. You can only go so big on buildings and the built environment reduces your capacity factor because there's loads of buildings blocking the wind.
