solar panels floating on water will power japan\'s homes

Today, water bodies are not necessarily built around them. They can be built.
Their campaign is more than just landfill and human
With the rise of the world, a large number of solar power plants have created beaches.
Clean energy uses lakes, wetlands, ponds and canals as a building site for sunlight
Photovoltaic panels for eating.
So far, floating solar structures have been announced in countries such as the UK, Australia, India and Italy.
In terms of production, the largest floating plant will soon be placed on a reservoir at Japan\'s Yamakura dam in Chiba prefecture east of Tokyo.
After its completion in March 2016, it covers an area of 180,000 m² square meters and can accommodate 50,000 photovoltaic solar panels, providing power to nearly 5,000 households.
It will also offset carbon dioxide emissions of nearly 8,000 tons a year. (
Because the EPA estimates that a typical car will be released.
Seven tons of carbon dioxide are emitted each year, equivalent to about 1,700 vehicles. )
The shancang dam project is Kyocera (a Kyoto-
Electronics manufacturers at headquarters)
, Ciel and Terre (
A French company that designs, finances and operates photovoltaic equipment)
Century Tokyo Leasing Company.
So why build solar panels on water, not just on land?
Placing panels on lakes or reservoirs can free up the surrounding land for agriculture, conservation or other development.
These benefits, however, pose challenges. (
See the relevant story: \"How green are those solar panels? \")
Overall, this is a very interesting idea.
If successful, it will have a huge impact, \"said Yang, a professor of engineering at the University of California, Los Angeles, who specializes in photovoltaic solar panels.
\"However, I do worry about its safety in storms and other natural disasters, not to mention corrosion.
\"Unlike solar installations installed on the ground or roof, floating solar power plants create relatively new difficulties.
First of all, everything needs to be waterproof, including panels and wires.
Also, without certain precautions, a huge Manual cannot be thrown into the local water supply system, such as compliance with water quality regulations, which is a related issue, especially if the building starts to change weather.
\"This is one of the reasons why we chose the Ciel et Terre floating platform, which is 100% recyclable from high
Density polyethylene that can withstand UV and corrosion, \"said Ichiro Ikeda, general manager of Kyocera solar marketing.
Another obstacle?
The threat of natural disasters in Japan is everywhere.
In addition to typhoons, China has become a hot spot for earthquakes, landslides and tsunamis around the world.
The planned floating solar panels in Japan will be on top of the Yamakura dam east of Tokyo.
The picture is provided by KyoceraTo, and the research and development team of Ciel et Terre brings \"big gun: wind tunnel of Onera\" to ensure that these platforms can withstand the wonders of nature, Air and Space Laboratory of France
The company\'s patented Hydrelio system will support the polyethylene \"frame\" of solar panels to withstand very high wind conditions that match hurricane speeds.
The system withstood the strong winds of 118 miles an hour.
Given the weather in Japan, why would it be the perfect spot and why build floating solar panels in the storm
Ring of Fire-
Embrace the land where the sun rises?
Reason: many countries can benefit from floating solar energy.
Japan is their poster child.
Japan, a mountainous archipelago, lacks land to use, which means that the space to build anything is getting smaller and smaller, not to mention building a large one.
Scale solar plant.
However, Japan has abundant reservoirs because it has a huge rice industry to irrigate, so more solar companies in Japan tend to irrigate construction sites with liquids rather than land.
All of a sudden, the terrain that is hard to approach becomes easy to approach.
Chi Tian of Kyocera said that with the increase in the number of ground available land in Japan is particularly difficult to obtain
In the past few years, the country\'s solar power plants have developed rapidly. (
\"Japan\'s solar energy has soared, but the grid needs to catch up. \")
But, he added, \"there are many agricultural and flood reservoirs in this country --
Control purpose.
There is great potential for solar power generation on these waters.
\"In the case of Japan, Ciel et Terre said that the frequent earthquakes in the region are also not worthy of attention.
In fact, the company says it shows that floating solar panels have another advantage over ground solar panels.
Eva Pauly, international business manager at Ciel et Terre, said: \"The earthquake has no effect on the floating photovoltaic system, which does not have a basic and sufficient anchoring system to ensure its stability . \"
\"This is a big advantage in a country like Japan.
\"The potential ecological impact of solar energy floating solar panel manufacturers want their products to replace more controversial energy sources.
\"After the Fukushima disaster, Japan needs new, independent renewable energy sources,\" he said . \".
\"After shutting down nuclear power and relying heavily on imported LNG, the country needs more independent sources of electricity. \"This up-and-
However, future aquatic substitution affects living organisms in the water.
This structure hinders the penetration of sunlight and makes the water colder and darker.
This may prevent algae growth, for example, said Lise Mesnager, project manager at Ciel et Terre, which may or may not be positive.
\"If there\'s too much algae in the water, shadow-
It may be beneficial to cast floating panels;
If there are endangered species in these waters, they may do harm to them.
\"It is very important for operators to understand what species can be found in water bodies,\" Mesnager said . \".
As companies have to comply with local environmental rules, these solar power plants are usually located in the center of the water, away from the banks of the river rich in animals and plants.
In addition, the company may prefer to be in man-
As there are less opportunities to damage the biodiversity of the region, the construction of the reservoir is not a natural one.
Will salt water be included in the future? More than three.
The oceans on our planet may provide alternative energy companies with a blank canvas to dot more active energy farms.
But moving the floating panel to the high seas is still something to come.
Chi Tian of Kyocera said that the change from the waves to the water level will bring a whole new problem area, which may lead to damage and operational disruption.
Ciel et Terre is experimenting with salt water
Friendly system in Thailand, but ocean-
Due to the high cost of offshore facilities, base-based plants may be impractical and it is more logical to produce electricity closer to the place of use.
At the moment, the company\'s goal is to build floating energy that saves limited space, cheaper than solar panels on terra firma, and most importantly, more efficient.
Ciel et Terre said that since its frame keeps Kyocera solar panels cool, the energy generated by the floating plant may be 20% more than the typical ground system.
The shancang dam project may be the world\'s largest floating solar power plant, but it is not the first
It\'s almost certainly not the last time.
