We get the rules on off-grid solar for 50 states; but no mention of wind.
Almost every photo I've ever seen of a US farm (homestead, rural dwelling, what have you) shows a windmill in the yard. I think these windmills are really for pumping water from wells, not for power generation; but why is it assumed that going off-grid implies solar power?
The short answer is that photovoltaics and associated storage have gotten much better (cheaper/efficient) over the past decade or two whereas a personal windmill probably doesn't look a whole lot different than it did 50 years ago.
There were small ("micro") wind turbines being talked up for a time but the economics didn't make nearly as much sense as their backers promised. I've also seen small turbines used for cabins where there's fast water and not a huge amount of sun. But, for the most part, solar's going to make the most sense for personal power generation for most people on an ongoing basis. (Generators can still be the most economical approach just to cover outages.)
