YouTube: 17 Apr 2015 –  Kyocera Corporation and Century Tokyo Leasing Corporation announced today that Kyocera TCL Solar LLC, a joint venture established by the two companies, has completed construction of two floating mega-solar power plants at Nishihira Pond and Higashihira Pond in Kato City, Hyogo Prefecture, Japan. The plants, inaugurated in late March, will generate an estimated 3,300 megawatt hours (MWh) per year in total — enough electricity to power approximately 920 typical households*.
Features 1. Floating solar power generating systems typically generate more electricity than ground-mount and rooftop systems due to the cooling effect of the water.
Features 2. They reduce reservoir water evaporation and algae growth by shading the water.
Features 3. Floating platforms are 100% recyclable, utilizing high-density polyethylene, which can withstand ultraviolet rays and resists corrosion.
Features 4. The floating platforms are designed and engineered to withstand extreme physical stress, including typhoon conditions.
* Based on average annual use of 3,600kWh per household. Source: Federation of Electric Power Companies of Japan.
The largest floating PV power plant in Japan: 13,744 kWp Installed on a water retention reservoir, Yamakura Dam, in Chiba prefecture. Project developed by Kyocera TCL Solar LLC Hydrelio® floating system provided by Ciel & Terre® International company.
