Not one state drives on the left...
If you're outside the states though, still why would a cop park facing oncoming traffic? I don't think I've ever seen cops (or people in general) do that except on side streets.
The only problem is that that DOESN'T happen. It takes so much energy to manufacture the panels, that by the time you recycle them; the energy that goes into recycling the components still offsets any savings.
Plus, you have to include the cost of batteries and the energy that goes into producing, maintaining, and finally disposing. Mining nickel is absolutely terrible for the environment, and Li batteries are only now coming to a point where they can be used in cars. I'm not sure of the environmental impact of obtaining Li though, so I can't comment on anything except monetary cost for those.
One could also profit in the sense that they save on heating/cooling costs since it's a more efficient system. 15 years, depending on how much you save, the new system could pay for itself. (I'm not sure what the break-even would be on most of them, though).
