Billboard Also Power Plant


The billboard really is capped with solar panels, producing 3.4 kilowatts of electricity during the day. This is more than the billboard uses on a day-to-day basis, so it actually does feed power into the grid. Though, of course, it's negligible. But we can't help but love it anyway.
