1/5th the price of nuclear.
Probably when combined with batteries it is half the price.
There are some colder areas in northern europe especially where solar doesnt work as well but they also tend to be better served for hydro (which can also store power).
Northern locales though have a much greater energy need for heating in the winter. So the "battery" solutions can often just be cheap heat batteries because there is not so much a thing as "waste heat" - that heat can be used directly without worrying as much about efficiency losses in conversion.
There are already a bunch of examples of Northern locales using these heat batteries - just heat up a big block of something when energy is cheap and solar/wind are overproducing, then use a network of insulated pipes to distribute that heated water.
So sad we could not apply economy of scale for nuclear... The main reason solar and batteries are so cheap is economy of scale.
How much would it cost to build out batteries which cover entire continent's electricy needs for say three weeks (as there can be 2-3 week lulls of no wind and no sun in Europe in the winter)? Cause that sounds like a lot of batteries. Not to mention, if a freak 4 week lull occurs, we'll go back to Middle Ages for a week.
Solar works also in the north, except in the winter of course, and it complements wind pretty well. So solar does make economic sense and is actively built in the north too.
