Night, sure. Doesn't work in winter though. (Not that that means we should stop building solar - we're still far from the point where it wouldn't make sense to build any more solar because we can't store the energy.)
I live in the UK. The ratio between solar output on a typically sunny summer day and a typical cloudy winter day is about 20. So your "a bit" is doing a hell of a lot of work there.
Right but it's not exactly the latitude that's the issue. On sunny days in winter I get plenty of power. The issue is the weather - only about 1/3 of the days in winter are sunny.
Yeah, my comment was a simplification - like most things trying to describe local effects globally are. The UK doubles as unusually cloudy weather and relatively short days.
