TCL Kyocera Solar, a joint venture created between Kyocera and Century Tokyo Leasing has announced an integrated mega-solar power plant built next to a device floating platform designed by French company Ciel & Terre.
Construction of the plant is scheduled to start in September 2014 and ended eight months later, in April 2015.
Kyocera Solar TCL want to commit to long-term construction of floating solar power plants using this type of platform. Indeed, as the choice of Building Sites for conventional solar power decreases, the company decided to diversify and to embark on this new activity. Kyocera said it had so far received more than 100 applications.
In Japan, with the rainy season, rainfall is more or less important. Therefore, there are many irrigation ponds and weirs are used in case of an excessive increase in river flow. Kyocera Solar TCL would thus aim to develop 60 MW floating solar power plants using these tanks throughout Japan for fiscal 2014.
With a total capacity of 2.9 MW, the first major project (11,256 modules of 255 watts) will be spread over two ponds located in Kato in the Japanese prefecture of Hyogo. However, in a first phase, a plant with a capacity of 1.7 MW will be developed on one of the two ponds and at the same time become the largest floating solar plant in the world.
The patented ‘Hydrelio’ Heaven & Earth consists of a floating structure made of high-density polyethylene (HDPE) with a lifespan of 30 years. Rugged and 100% recyclable, it is resistant to ultraviolet light and corrosion. Furthermore, due to its architecture and materials all have the ability to face the storms reaching almost 200 km / h.
Moreover, floating solar power plants have a cooling power attractive because of their installation on the water. Therefore, they are expected to generate a larger amount of power relative to the solar power plants installed in the floor or roof. Lastly, by covering the water surface, on the one hand they prevent water to evaporate and secondly algae proliferate.
To date, this type of platform has already been proven in Japan in several projects of various powers:
Okegawa – 1.2 MW installed power
Maenoike – Power installed 850 kWp
Kawagoe – Power installed 700 kWp
Yasugi – 1.2 MWp installed power
Kyocera solar TCL has developed solar power plants on 28 sites in Japan for a total capacity of 92.8 MW.
