Rooftop solar is incredibly popular here in Australia. I think it’s something like 33% of houses have it. We also have a great climate for it.

I have solar on my house and am seeing around 50% self sufficiency overall. Of course with this much saturation, the rate you get paid for feeding back to the grid is quickly dropping to zero. So self use is the game now.

The problem is now shifting to home batteries and storage. Because peak power household use times are in the evening when the sun is not shining.

Conversely prices with rebates have gotten very cheap recently.

I'm getting a 48kwh battery put in with a 3 phase inverter for $6500 AUD in like a week.

Back when solar was much, much more expensive this sort of thing mattered. Now the panels have plunged in price so much, you just deploy more panels (cost of install and other central stuff is the same) and/or accept the longer payback period.

Cold climates do better than one might expect because the colder a solar panel is, the better it works.

It's not really, the sun doesen't rise above the horizon for over a month where I live. quadrupling zero output is still zero. The country has massive renewable so by the time solar would generate something, electricity is already super cheap

You're clearly an outlier, 99% of installs will not have that problem.
The issue persists across the nordic countries, I argue that climate matters a lot to the type of power you're looking to generate.
