Ran across this and thought it was interesting. Apparently solar panels deployed over 30 years ago are still online and providing 80% of their rated capacity.

That changes the calculus on PV lifecycles, and largely dismisses the notion that they'd need to be replaced wholesale after just 20 years of use.
