Basically there is almost nowhere that wind wins over solar. At least at consumer scale.
Anything between late october and early march?
I can't be arsed to find it again, but there's a company that does solar installs in my country (which to me sounds like they'd be the last people to downplay solar's capabilities) and they have production statistics from some of their installations on their website. I checked out a couple and May or June tended to be about 30x higher than December. I think May was actually the peak production month which in hindsight makes sense because in June the midday sun is really high in the sky and the morning and evening are somewhat more north than you'd normally get so they don't give you much extra.
December, meanwhile, gets about an hour of useful sunlight a week.
This is only around 60 degrees north too, it's gonna be worse for anyone that lives in an actually northern area.
