Water and solar panels go hand in hand, even though you might not think so. Floating solar farms are a global phenomenon that offer numerous solutions to various problems. By putting a solar panel in a reservoir situated behind a dam, evaporation is decreased and the water flow is shaded.

In dry conditions, this can prevent 90% of the water from being lost to the parched air. Solar panels generate sustainable electricity while also preventing dam water from evaporating. Not only that, but this picture, which may have been taken with a PowerVision PowerDolphin Wizard—a $999 water-capable drone—on Amazon, also shows how awesome they look.
