China pushes the boundaries of solar energy with large offshore platforms.

What if fields of photovoltaic panels end up in the open ocean? This is a project led by the Huaneng Group in China that has a prototype of a floating platform equipped with different types of solar panels. Its effectiveness and durability against marine elements will be evaluated for one year.

As for producing offshore wind turbines.EnergyEnergyChina has begun tests of large platforms. A foreignerA foreigner Carrying photovoltaic panels. Yellow Sea No. 1 is a prototype platform operated by Huaying Group. It is located in the sea. PeninsulaPeninsula Hexagonal from Shandong in China, it covers an area of ​​1,624 m² on the water. There are 434 photovoltaic panels on this platform.

For the purposes of this full-scale test, engineers put together three different panel technologies. The capabilities to determine the strongest and most efficient and effective configuration in energy production are also not the same. The platform is nine meters high and floats thanks to 64 buoys installed around the lower structure. It is anchored to the seabed by cables that allow it to maintain its position.

The travel and design of the platform allows this to be tolerated. The wavesThe waves With a height of 10 meters. The presence of waves is a particularly big problem with this platform. Because of these, salt crystals accumulate on the panels and affect the conversion efficiency. PhotoelectricPhotoelectric. Not only that, seawater corrodes both photovoltaic components and electrical systems.

One year of testing

It is for these reasons that the platform is raised to avoid contact with sea water, which occurs approximately 30 km offshore, in waters with a depth of 30 m. There resistanceresistance au take outtake out And the strength of the whole will be confirmed along with the waves. Electrical efficiency and maintenance requirements will also be considered.

If the result is positive, this type of platform will be developed and support existing offshore wind farms. The Chinese project is not unique in the world; Other companies are also testing this type of prototype. A model, developed by NoviOcean, is also one of a kind. HybridHybrid. This allows for the combination of wind, wave and solar energy.
