It's not about comparing to coal but rather about comparing to other good alternatives, with that being nuclear.
Energy return in investment is <10x for solar, but more like 100x for nuclear. We have an energy budget to solver climate change. This is nothing to do with how much things cost.

Rooftop solar is worse, but 4x worse than wind/nuclear is still quite good (and non-rooftop solar is almost certainly better than that). Solar's energy return on investment is higher than 10x by my searching, and we should be mass producing all three technologies at this point.
