The Te, Ag, and Cu is plenty valuable (especially old high end panels with 50-100g of silver), and developed nations which already have recycling fees that build recycling supply chains and so reduce costs of processing will pay for them. There have already been trials for industrial scale reprocessing of the Si into new panels -- which should give old monocrystalline panels similar value after reprocessing to new due to material reductions offsetting the labour. It looks like there is some motion towards responsibility though https://www.solarrecycle.org/copy-of-vendors https://www.solarrecycle.org/copy-of-vendors And even paid decomissioning if they have some limited life left https://fabtech.net/ https://fabtech.net/ Plus even if you don't tear it apart it's still a piece of hail resistant glass that could have various uses. Frost the top and you have a table. Find use for 20 such items in your lifetime and none will make it to landfill.
