Do you have week long blackouts currently? In any given year you can count on a week where a panel only produces 10%. It just has to be cloudy or rainy. However much solar we add, even with storage to get through a night, needs some other source to get through the cloudy week, unless we are ok with blackouts.

A panel. Panels spread over hundreds of thousands of square kilometres produce power averaged over that area, so they're much more consistent and predictable.
HVDC lines help with this a lot. It has gotten to a point where there are serious plans to build a long, undersea HVDC line from the UK to Morocco which, get this, is poised to cost less than the equivalent(GWh delivered annually) Hinkley Point C nuclear power plant:

That's how cheap the combination of solar and HVDC is.

Glad it will work there. There has been local opposition to new transmission lines in the USA (see Maine recently) so when folks say “just build powerlines” all I can think of is the difficulty of the land assembly and permitting. Technically it is easy, it is all the humans in the way that make it hard.
Solar panels are cheap and the market appears to be fine with unreliable power[0] if it's cheap enough.
[0] Unreliable, but predictable that is. You can estimate with decent confidence what the weather will be like tomorrow and you can definitely tell what it's going to be a few hours from now, so energy auctions a day ahead are feasible.
