In recent years floating solar farms have been popping up on water bodies around the globe. While typically more expensive to initially install, floating solar facilities have several notable advantages, including:
- Less use of productive farm land or valuable lands elsewhere
- Cooling effects from the water body makes the solar array more productive
- Reduced evaporation – up to as much as 70 percent
- Fewer algae blooms
- Limited to no tree removal is necessary

It should be noted that there are unique challenges related to floating solar farms such as impacts from wave action and/or storms, particularly on larger water bodies; variable water elevations; as well as the need to design safeguards into the system whenever you have electricity infrastructure placed on or near a water source. Some of these challenges are why many floating solar farms tend to be constructed on treatment ponds, reservoirs, or retention ponds with managed surface water elevations.

The following lists identify the largest floating solar farms in the United States, Asia, and Europe. As the data indicates, the United States, in fact the rest of the planet, has a long way to go to catch up with Asia. The rankings are listed by megawatts (MW).
