Waste from solar? Just handle it like you'll be handling the much larger volumes of ordinary waste from all industrial activity. It's not like solar is creating some distinctly different category of waste like nuclear does.
You missed the second half of the equation. For the long foreseeable future, solar will still require the use of natural gas for many seasonal events. Nobody seems to worry about storing the waste from that but is very concerned about the tiny amount of nuclear waste.
I didn't miss it, I deliberately ignored it. Short term, the issue is not inherent waste from renewables, it's how rapidly fossil fuels can be displaced. Renewables are massively better than nuclear on that score.
Longer term, gas is phased out, so the waste from it is irrelevant (or, rather, the CO2 was has to handled if any is still burned.) Renewables do not require natural gas. If natural gas is used for covering dunkelflauten in the short term, that can be handled by other non-fossil means (like e-fuels burned in turbines) in the longer term. And this will likely still be cheaper than using nuclear.
