Japan’s Two Massive Floating Solar Power Plants Are Now Ready To Power 1,000 Home

Japan’s two enormous floating solar power plants have just been completed and is ready to power 1,000 homes without taking any electricity from the grid.

Over the past few years, Japan has managed to double its solar power capacity, and if plants like these are as efficient as they’re expected to be and there’s no reason why it can’t continue to tip the balance in favour of renewable energy sources.

The plants are located on the Nishihira and Higashihira Ponds in Kato City, which is part of the Hyōgo Prefecture of Japan. Built by energy company, Kyocera Corporation, and the Century Tokyo Leasing Corporation, the plants were installed in just seven months, and according to Liat Clark, together their 11,250 modules are expected to generate 3,300 megawatt hours (MWh) each year.

Firstly, in a country like Japan, where land space is scarce, taking up water space is the perfect solution. The most interesting part is that, the plant is also typhoon-proof, and because it uses the water below to cool itself, is actually more energy-efficient than if it was built on the land.

A report by Korea Water Resources Corporation found that the lower temperatures of the floating modules mean they are 11 percent more efficient than land-based equivalents. The report identified unsolved issues with the plants, too, however. It said the study had to discard data collected when the panels moved in the wind, and said research into new mooring systems was ‘continually needed’,” explained Clark .

 

HMMM! This sounds very promising! I hope these plants will live up to their potential and countries should have to consider this approach, as well.

    Floating Solar Power Systems are wonderful Ideas. 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. Recently, Restoring Force Strengthened Mooring Systems have been used in South Korea. You can see the Restoring Force Strengthened Mooring System in Ochang Dam, South Korea. I N I WORLD
