You're missing energy storage there, and also the logistics of producing that many solar panels.

  We have better chances of producing that many solar panels than we have getting Gen4 reactors before 2050. As for energy storage - there's a lot of possibilities: 1) electric cars acting as buffers. Particularly rarely-used vehicles could earn some side money for being used in a smart grid. 2) battery storage like Tesla constructed in Australia 3) hydro pumped storage In particular, base load could also be generated by permanent renewable energy (e.g. geothermal or running-water hydro power aka dams) to ease the requirement for energy storage.

    > 1) electric cars acting as buffers. Particularly rarely-used vehicles could earn some side money for being used in a smart grid. Bidirectional V2G systems only exist as demonstration projects now, and we'll need a bunch of time to ramp that up. It requires a lot of EVs, lots of grid updates all over the place, and for people to willingly participate at a meaningful scale. This won't be cheap and the grid we have now can't handle it.

    >3) hydro pumped storage Not likely to be a widely useful storage mechanism except in very specific geography. https://dothemath.ucsd.edu/2011/11/pump-up-the-storage/ https://dothemath.ucsd.edu/2011/11/pump-up-the-storage/

  Not just producing that may solar panels, but maintaining them, replacing them, dealing with the waste panels (yes, panels do need to be replaced). You just don't chuck out a field of solar panels and ignore them. Modern reactor designs - you do basically ignore them once they are initially set up.
