And panels last forever, ensuring that Europe won't have to deal with panel manufacturers ever again.

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.
