Here is a great comparison of land use for different power sources, based on power output: https://ourworldindata.org/land-use-per-energy-source https://ourworldindata.org/land-use-per-energy-source Solar is roughly on par with coal, depending on the exact type of solar technology used. Of course you can put solar on existing structures, in which case the land use is negligible and on par with nuclear. Regarding energy input, solar panels break even after about two years, I think (no source on hand currently). It would be quite easy to have solar panel production run entirely on renewable energy input. Regarding the other resources, you can't really compare energy sources to one another, as all are using vastly different inputs and have different challenges regarding disposal of waste and recycling. You'd have to make a judgement based on impact. I.e. coal is really bad, because it produces CO2 which has potentially society-ending consequences. Nuclear has challenges, because the waste remains radioactive for so long. My personal impression is that solar has some challenges, but those are manageable and likely can be mitigated by regulating disposal and recycling of old panels.
