30 years is typically the lifetime estimated for a utility scale solar facility (with leases for land following the same duration), at which point it can either be repowered or everything torn out and the land returned to original state.
It’s possible this land is permanently tainted for agricultural use, but too early to assume, as PFAS remediation technology might advance quickly.

https://en.wikipedia.org/wiki/Agrivoltaics is a potential implementation if bioremediation proves both feasible and scalable. Perhaps the land is ready to go back into ag use if remediation can be performed in parallel with the thirty year lifespan I mentioned. If not, it carries on as solar production.
