You can easily find solar panels on rooftops, in fields and even on a plane, but now solar technology has found another way to leave firm land in the form of two floating solar farms in Japan.

Kyocera Corporation and Century Tokyo Leasing Corporation announced this week that their high profile plans to build two “floating mega-solar power plants” at Nishihira Pond and Higashihira Pond in Kato City in Hyogo Prefecture have been successfully completed.

The companies, which have worked together through the joint venture Kyocera TCL Solar LLC, announced that the projects were officially inaugurated last month and are now providing power to the grid.

Combined the plants boast 2.9MW of capacity and are expected to deliver 3,300MWh of power a year, sufficient for 920 typical households.

Electricity generated from the project will be sold to the local utility, The Kansai Electric Power Co., Inc., through Japan’s feed-in-tariff system, which has played a key role in establishing Japan as one of the world’s largest solar markets in recent years.

Floating solar arrays boast a number of benefits over conventional solar farms. Firstly, they do not compete with agricultural land and as such have no impact on food production. Secondly, floating turbines reduce evaporation from reservoirs and reduce algae growth. And finally, the cooling effect of the water tends to boost the conversion efficiency of the panels, leading to increased power production.

    Floating solar power system is a wonderful idea. And it’s very important to maintain effectively same direction and position on the water for floating solar plants. Because directional change of solar panels reduces electricity production. So floating solar plants also need the directional control mooring systems for their parked positions. Azimuth and position change of floating solar plants caused by wind, waves and external forces. Restoring Force Strengthened Mooring System for floating solar plants has been created in South Korea. This Mooring System generates Restoring Force immediately when floating solar plants are being rotated or moved on the water.

    In addition, you have to reduce vibration to install floating solar plants. Because, it can make micro-cracks to floating solar panels and the durability problem of floating solar plants. The risk of power loss in PV modules due to micro cracks is increasing. Vibrations caused by wind, waves and external forces. New Type Floating Body Stabilizer has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when floating solar plants are being rolled, pitched and yawed on the water. Recently, Restoring Force Strengthened Mooring Systems and Floating Body Stabilizers have been used for floating solar plants in South Korea. You can see them in Ochang Dam natural reservoir, South Korea. I N I WORLD
