I suppose with so many houses having solar panels these days, this scene will become more common.
How often do you suppose a building demolition company would bother to remove solar panels from a roof before wrecking? I suspect not very often, if ever. Certainly not in this case.
Here's something seen a few days ago. Thought I'd take some pics. Amazingly, one of the two panels dropped with the roof (and still visible in the rubble) turned out to be intact. No damage other than one slightly dinged frame corner. In late afternoon sunlight it develops 41V oc, 4A sc, which is pretty close to spec.
Old houses, partly demolished, are very atmospheric. Could have posted more pics but not on topic.
Edit: It turns out the front glass sheet in solar panels is tempered safety glass, and shatters into tiny pieces. The backing sheet is fiberglass, and the front glass, cells, and backing sheet are all held together by a clear rubbery glue. So there's no chance of recovering intact cells from broken panels.
