That's a great catch ! Thanks for this. For anyone wondering, 25 years is pretty common as a baseline for PV [1] but a good amount of them should be able to go for longer, say at least 30 years. As a comparison, the average nuclear power plant in France is 37 years old, and the french authority considers obvious a 50 year life expectancy, and 60 is being floated [2], but no idea where they got 80 from probably from the US extensions being floated [3] — 92% capacity factor are official measurements though, it's not unrealistic [4]
