The world’s largest floating photovoltaic (PV) power plant, with the capacity of 40 MW is now connected to the grid in China. Built by Sungrow, a Chinese manufacturer of PV inverter systems, the installation is based in a subsided area of mining which is flooded due to the rainy weather with depth of water ranging from 4 to 10 meters in Huainan, a coal-rich city in south Anhui province.
And the seriously mineralized water makes this area valueless.
"The plant not only makes full use of this area, reducing the demand for lands,
but also improves generation due to the cooling effects of the surface," explained a professional from the local government.
The plant works exactly as a typical solar farm, only that this one floats on water and is specifically designed to work in environments of high humidity and salt spray.
Floating solar panels are a relatively new addition to the field of power generation. They are advantageous over traditional systems because they put otherwise useless water and land to good use.
The water naturally cools the system and the ambient temperatures, improving generation and limiting long-term damage from heat.
Finally, the floating PV arrays, customized to work efficiently despite higher levels of humidity, prevent the evaporation of fresh water.
The largest benefit perhaps is the new motion to provide a means of clean technology to power some parts of the world.
