No it isn't.
Wires still might be worth it, but these are all close enough to the equator that you can just over provision locally without issue if you prefer.
> It's more than 1000km from the places that get cold
Solar panels work better in the cold. The issue is with how far from the equator Sweden is, not how cold it is.

In the US Northeast solar generates around four times as much in July as December. This is sufficiently bad when what you need is more power in the winter. Paris is a little worse. Sweden is significantly worse.

If I need 25% more output in the month when solar has 75% less output, how much do I have to over-provision?

Places that need more electricity in the winter because they're cold are cold in the winter because they're further away from the equator.

Nope, it isn't. Solar is cheap and the costs are continuing to fall quickly. Generating 5x more power in the summer than needed is perfectly fine and just a nice added bonus.
Wires are probably a good idea to reduce that number, but with how solar panels are dropping in price traditional forms of electricity generation (nuclear, fossil fuels, etc) just won't be competitive at that multiplier even without them.

Temperature has a lot to do with ocean currents. NY and Sweden overlap in how cold they are (taking the right parts of both). The southernmost point of Sweden is at 55.3 degrees north, the northermost point of NY is at 45.0 degrees north. They aren't even close to overlapping in how far north they are.
