I think solar+battery usually also involves overbuilding the solar capacity by a lot and running some HVDC lines. A mix with nuclear and wind seems smart to me,

I think solar+battery usually also involves overbuilding the solar capacity by a lot and running some HVDC lines. A mix with nuclear and wind seems smart to me, but I wouldn't be shocked if some cloudy places successfully manage solar+batteries in combination with HVDC and/or having some easily-curtailed industries in the area.
