So.......correct or no? Is this your way of agreeing?

Not correct. As the other fellow said and you're conveniently ignoring, you're grossly overestimating the degradation. We're regularly designing utility scale solar with a 35 year life.

Energy storage is trickier, as degradation is much more pronounced, but there are so many levers you can pull to make money off a battery that it still works.

I said 25 years, you said 35. That's not grossly overestimating the degradation.

And when they're useless, they're not recyclable. Glass doped with rare earth metals. How the hell do you recycle this?

You said they degrade at 3-5% per year, when it's more like 8-10% over the full 25 years. Yes that's a huge difference.

You realize designing for a 25 year life does not mean we aim for the panels to hit zero output at the end, right?
