i read an article that the nordics actually gets as much sun as southern europe, if you count the whole year. Its as good a place for solar as anywhere else.
The summers are sunny all day and night. The problem becomes how to store the energy until the dark winter months.
(There are solar panels that doesnt need heat just light)
