We use more land for golf courses than photovoltaics.. I’m not trying to say that golf courses are inherently bad (even though they’re not exactly environmental friendly) but it shows how little space photovoltaics actually need compared to other things.

Also, don’t underestimate the amount of material a nuclear reactor uses. A single cooling tower of the Phillipsburg NPP weighed 32,500 metric tons. That’s roughly 250-500 MW in solar panels, and then you haven’t even built the reactor or the generator. I found sources talking about half a million tons per nuclear plant.
