Basically if we are lucky we hit 5% of a typical summer summer day for an hour maybe two. As the days are less then half as long you end up with ~1% the production vs summer.
But in reverse the panels are really good during the summer as the days are very long. This is why people bother installing solar here.
I don’t know the numbers for southern Sweden but for Stockholm level you get maybe 5% to 10% of the production you get in the summer.
Here in Finland we have it even worse but I know where to find the numbers.
