We'd have to solve some environmental problems with solar panels if we wanted to do that. Panels have been found to leak lead and cadmium into the environment. We should probably keep them away from our food until that's fixed

That paper doesn't support your claims. They didn't test for lead leaching, and they tested pulverized solar panels in strong acid. Moreover, they were cadmium telluride solar panels, which have been obsoleted by cheaper polysilicon. Polysilicon PV panels don't contain cadmium and don't contain a significant amount of lead.
