Times have change. Solar had the break through about 5 years ago in average but oh surprise it depends on the geographical, political and economic environment. I would say in North Norway it will never be a success...
..or may be not.
The University of Tromsø in the far north of Norway tested panels in 2018, panels at different angels and also bifacial panels that are becoming popular.
A positive factor in the north is 10% increased efficiency for 20 degC reduced temperature....And fixed bifacial panels may use reflection from the snow behind, and the night sun during summertime...
In one year run (which they say was an average year wrt clouds and sun), they achieved 960 KWh pr. KW panel.
This is comparable with places further south where clouds are normal, like parts of UK or north of Germany.
As cost come further down it is not unlikely we will see the first grid scale solar plants north of the polar circle 😎
