By "Northen" I assume you mean Europe, and (most of) USA?
I live near the 33rd parallel South. Since installing solar my annual grid requirements are around 30% of before solar [1] ‐ even as my actual consumption has risen [2].
As far as "Northern" goes countries in my latitude north (or better) include India, Mexica, all of Africa, most of China, and so on. So for most people living in the north it is compelling [4].
[1] a very large fraction of my grid usage is really cold, wet conditions for 6 weeks in winter. A combination of low generation and high usage for heating.
[2] cooling in summer is free, so we run the aircon a lot more. Plus things like slow-cooking etc are free as well.
[4] my return on investment (grid cost of generated electricity over capital invested) is 16.7%. Projected lifespan is 10 years for battery and inverter, 25 years on panels, 50 years on wiring.

People wrongly assume that you can put Europe and the US in the same basket (because temperature-wise climate is comparable), but half of Europe is further north than Montreal, and almost all of it is beyond Philadelphia, so no you can't really say “Europe and most of the US”.
