A question that crosses the streams: how do we get a solar panel that will last for >100 years?

I have found that the entire solar industry is focused on a 20-30 year lifetime for panels. And the marketing today is that the panels will then be replaced, and "solar waste management" companies will be necessary. I don't see any physical reason that requires a panel lifetime that short, but the economic incentives (and the shorttermism) are perfectly capable of explaining what people are doing.

As far as the EA movement ... I have found they tend to focus entirely on "AI risk" or "fighting diseases in Sub-Saharan Africa", and ignore everything in the middle. Perhaps they will prove that wrong.
