Historically panels are generally considered to be exhausted after 30 years of service, although even that means they're down to 80% of their original capacity.

The more failure prone component is the inverter, by a huge margin.

Warranty lives tend to be in the 20+ year range and potential lifespan even higher, so .. kinda?

By coincidence I had my solar panels installed round about the time construction started on Hinkley Point C. They've already paid back their installation cost. I don't expect to replace them any time soon.

You have 20 years after buying them to set up a local supply chain.
