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.

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 degraded panel in a suboptimal position is probably not worth the effort to install and the resources that would go into supporting it.

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.

I've seen people do fences with entirely new ones both because fences are somehow absurdly expensive and solar panels themselves are quite cheap. Especially if it starts near the house anyways the cost of running a line doesn't seem gargantuan. At the point where you're replacing them in optimal conditions I'd look at it less as a solar panel and more as free building material that incidentally generates some power
