The idea of floating solar panels out on water seems to make sense, right? Well, maybe. Waterborne PV adds another wrinkle to the task of maintaining and repairing solar panels. Finding suitable bodies of water is a whole ‘nother can of worms. Nevertheless, other countries are shaking the floating solar panel tree and now the US Department of Energy wants the US to play catch-up.

The new study — the first of its kind in the US — comes from the Energy Department’s National Renewable Energy Laboratory in Colorado.

They answer the suitable site question right off the bat:

…researchers estimate that installing floating solar photovoltaics on the more than 24,000 man-made U.S. reservoirs could generate about 10 percent of the nation’s annual electricity production.

You don’t say! Yes, we do:
