Solar still has some huge problems when it comes to seasonality and day/night cycle. You either need massive battery build out or some other form of energy to handle base loads and/or offset when solar isn't producing enough.
Not saying solar isn't part of the future, but we literally can't just rely on solar.
Battery tech is getting super good though, and the materials are recyclable. If solar becomes cheap enough we could even store it in creative (but less efficient) batteries like lake batteries or weight batteries and the like.
This isn't a problem at City scales and beyond. You just can't buy a bunch of nazi batteries so there isn't a corp greasing politicians to build it.
