Not necessarily Put the panels on lakes, reservoirs, and at sea, and of course, roofs. Particularly for reservoirs, panels can provide shade for fish, and theres the potential for pumped-hydro storage with tiered reservoirs - or at least substitute hydro output when the sun shines. As for toxic metals in solar panels, they're locked away in the panel. Rather like vitrification for nuclear waste encapsulation. Just make some solar-panel-only landfills, which will become future toxic-heavy-metal mines - this stuff all came out of the ground, it can temporarily go back.
