Is that true that panels only last for about a couple of decades? A quick google suggests that that's just the warranty period and they just lose about 1% efficiency a year.

This stuff depends on the panel. Panels may still function in 40+ years, but the decreasing power output becomes very significant.

I am more saying losing total output in ~30+ years and ~0.5% to ~1% power output until then is about the same as losing 1 year of power output 20 years from now.
