With hydropower dams or reservoirs, it's especially important to prevent evaporation so water is available for electricity and irrigation. Floating solar panels are ideal for this purpose. They keep water from evaporating in such dams and reservoirs and save fertile land for agriculture and they are highly efficient because water cools them. They also offer a cooler operating station for workers. At sea, floating solar panels generate up to 15% higher yields because of the solar reflection between the water’s surface and the clouds.
