Heavy clouds and zero wind, for weeks? That's a once-a-century freak event. Just build gas peaker plants if you are worried about it. You could even add carbon capture, but constructing it might emit more than it will ever capture...
I assume you never tried measuring the output of a solar panel when it's cloudy. It's 10-15% of a sunny day. Closer to not working than working.
On a rainy day that drops closer to 20%.
As an aside - cloudy days avoid a problem I have with shade. In winter, at 3:30pm, the sun goes behind a tree and my production plummets to near zero. If there's cloud cover the sunlight is far more dispersed and there's no "shade".
And you’re still able to power your entire home? What if the rain lasts for a few days, which is pretty common in many places.
I did have one rainy day back in the middle of Winter that was 16% but that will end up being literally the worst day of the year.
It also has relatively wealthy people, living in lots of individual housing units. If you wanted to design a country that's perfect for rooftop solar your imagination might come up with Australia.
That said, Australia ought to be able to run almost everything off solar given how sunny it is, and instead solar is a distant second behind coal for electricity production. So there's plenty of work left to do.
Our energy grid can't currently handle the ability to charge electric haulers locally at any scale let alone to move an entire city's worth of energy, so the solution is not to 85x the national electric grid all at once.
But to give them due credit, they believed in this vision and put in the hard work to make sure it became true.
If the US decided to divert half of the Pentagon's annual budget to electricity, the US could absolutely build the infrastructure to transport electricity thousands of kilometres.
Also, it’s weird to talk about Florida when, say, Arizona and Utah, etc. are right there. Even Wyoming despite being further north has over half of the month sunny in the winter. One thing to remember is that we could power the entire country using solar with a fraction of the land currently used to produce corn for ethanol so we don’t even need to substantially change land use, just stop subsidizing inefficient fuel generation.
These usually drop ambient temperatures across Canada and the northern US to below -20 C, and produce generally high winds. This combination of extreme cold, cloud cover, and high winds last for multiple days, often longer than a week.
The wind plus cold means that many wind turbines cannot operate and the cloud cover and shorter days mean that solar is barely generating any energy.
That's literally CCP state controlled communism !! More specifically, that's what the Gansu–Zhejiang UHVDC project has as an overhead transmission line length (2,370 km in international units).

The GP might be in the group that don't much like that kind of thing.
