Around here late morning to mid afternoon (11 am to 4 pm) is now off-peak, alongside the old 10pm to 6 am.

There's also, like... winter. I'm fairly sure there's a calculation somewhere you could determine the number of deaths this will cause with pretty good accuracy.

Solar is never gonna be a complete solution. At the end of the day, we could do it more efficiently by just building suns here on earth for the panels, but of course then you've achieved fusion and you're already generating more than solar could ever hope to. We shouldn't hinge our future on half of a technology.
