How long would you say a properly installed panel from 2000 made it in practice? How long would the modern equivalent installed in 2025 be expected to make it? And how many replacement events does each of those make for over the course of your life?
Do you contest my earlier claim that solar is roughly equivalent to wood siding or an asphalt shingle roof?

Using 30 years as a lifetime for solar panels is risky as there are no solar panels running for 30 years, not even close. Never mind the lifetime of the power wall battery and the inverters.
I bought a 40 year "premium" asphalt roof. It barely made it to 20. A regular asphalt roof, perhaps 10 years. Now I have a metal roof.
