I'm curious on how easy would be to with solar with the knowledge we have now in material science

  Impossible, you wouldn't have any of what's needed to build a solar panel. No rare earth, no plastics, &c. they're all byproducts of the virtually free fossil fuel we had at the begging of the industrial revolution. You could find oil oozing out of the ground in some places

    A "solar panel" does not have to be a photovoltaic panel. A much simpler panel can heat water to use in a steam turbine.

      We probably wouldn't even be able to source iron ore at that stage, let alone process it to make any kind of useful turbine, but let's say you make a working steam turbine from wood and clay, a DIY solar powered steam turbine is quite a few steps before modern CPU

        Depending on your location, there are places where you can't not find iron. Recycle! Civilization might be lost but all that processed and purified iron didn't disappear, it's just hiding under some dirt.

        There is so much scrap iron. The quality might not be the best but it’s easy to get with time and hand tools
