Used panels are cheap because of where we are in the improvement curve. Let's say you're a large business with a factory rooftop full of 100W panels that was installed installed 10 years ago. Today, you can upgrade that rooftop to 300W panels without any additional footprint and often for less than the original deployment cost (adjusted for inflation).
Those old panels have to go somewhere and still have at least 2/3 of their life left. Probably more because we're finding out that well-made panels do not degrade as quickly as previously thought.
The used panel market (in the US anyway) might dry up soon if the tariffs stay in place, as that will make a lot of customers reluctant to upgrade due to greatly increased costs. But I guess we'll see. I've been wrong before.
