Twenty years from now a lot of them will be due for replacement and I expect enterprising recycle co's will figure out a way to separate materials and make a buck.

Solar makes a ton of sense where there is no grid like India, Africa, S. America. It still makes sense for high demand uses where energy costs are high like schools and retail. It makes no sense for my current residential use with bills averaging $50/mo.
