Yeah, but if you're a residential solar customer with limited roof space and/or a weight limit, the old panels become a bit of a liability.

Realistically a lot of it is going to end up in Africa on way or another.

I've also seen listings for used solar panels one Chinese wholesale marketplaces for 1/3 - 1/2 of the new price.

80% efficacy for 50% of the price sounds like it's a great deal if the tradeoffs don't matter.

Could just use them for fence or sunshade on your property somewhere where they're not getting optimal sun. I mean if the other option is to throw them away might aswell.

a better re-use case would be one where the downsides aren't exacerbated but a new build panel isn't justified. also solar panels are supposedly highly recyclable.
