Having a quick look at requirements for solar plants, it's easy to check that typical ones occupy about 14km2 per GW of power. So solar requires several orders of magnitude more land than nuclear (taking into account actual power production: 80% yield for nuclear, 15% at most for solar).
Furthermore, it's also easy to check that contrary to nuclear plants where land grab is largely a safety zone, a solar plant actually covers land with hardware, most of it requiring much more rare earths and exotic materials than nuclear power plants (where 95% of stuff in weight is concrete and steel).
The actual take for me is the following: in the coming years, we'll go through a huge reduction in energy availability, because fossil fuels are at least 80% of world energy consumption and they'll run out at some point anyway; which implies a huge reduction in economic activity. This is absolutely unavoidable in the next few decades unless some actual miracle such as cheap and easy cold fusion happens real soon now .
