Floating solar power generating systems typically generate more electricity than ground-mount and rooftop systems due to the cooling effect of the water. They also reduce reservoir water evaporation and algae growth by shading the water.
Kyocera and Century Tokyo announced today that a joint venture established by the two companies, has completed construction of two floating mega-solar power plants at in Kato City, Japan. The plants, inaugurated in late March, will generate an estimated 3,300 megawatt hours (MWh) per year.
The floating platforms are 100% recyclable, utilizing high-density polyethylene, which can withstand ultraviolet rays and resists corrosion. The floating platforms are also designed and engineered to withstand extreme physical stress, including typhoon conditions.
This is not the last you will hear of floating plants says Nancy Owano in PhysOrg. “Liat Clark in Wired.co.uk said “floating solar power plants are having a moment in the sun.” He said some “are starting to appear in the UK, while larger scale projects are also planned in California’s wine country.” BusinessGreen also mentioned plans for arrays on reservoirs in California. Last year, Young-Kwan Choi of the Korea Water Resources Corporation, discussed at length Floating PV Systems in terms of power generation and environmental impact. He wrote that the floating PV system demonstrated in his paper was a new way of generating solar energy, using the water surface that is available on dams, reservoirs and other bodies of water. “This method has an advantage that allows efficient use of the nation’s soil without bringing damages to the environment.”
