LONGi delivers PV modules to floating panda power station

179

Integrating the picture of a massive panda in its design, the floating plant is another inventive project by the Panda Green Energy Group after its Datong project, the world’s initial ground “Panda” power station, for which LONGi also brings modules. The project has a total set capacity of 100 negawatts, with the overall floating system solution and body supplied by Sungrow. There are three kinds of floating bodies: main, secondary and aisle, with this project accepting a tailored black aisle floating body to show the image of the panda.

Li Xu, a member of the LONGi sales team, recalled: “In 2017, LONGi supplied monocrystalline modules to two arrays of the project. In order to actively support the project construction, our modules arrived at the site ahead of other suppliers. As a result, the two arrays were the first to start grid-connected power generation.”

Self-cleaning capability of floating power plants

The project reached full-capacity grid-connected power generation in November 2018, and is expected to produce more than three billion kilowatt hours of clean electricity for the local area over its 25-year life cycle.

The “Panda” floating plant is located in a coal mining area of Huainan that is prone to subsidence, which in the past was not a vast lake area as it is today. In flat areas like Huainan, the water table is high and, after the ground collapsed due to the mining activity, the groundwater was exposed. Under the water, there were a number of ‘disappeared’ villages.

In recent years, China has seen a sharp increase in floating power station projects and, indeed, has become the world’s most important market for projects of this type. The construction of floating power stations in coal mining subsidence areas can not only regenerate “wasted bodies of water” into a brand-new power station carrier, but also maximize the self-cleaning capability of the stations themselves, purifying the water by covering the surface to reduce evaporation and inhibit the growth of microorganisms.

Up to 10% output gains over ground-mounted installations

In addition, floating power stations can make full use of the water to solve the cooling problems encountered by ground-mounted stations. Data from several research institutions shows that, compared with ordinary ground power stations, the energy gain of floating stations can be as high as 5 to 10 per cent, with terawatt-level growth potential in the future.

Up to now, LONGi has supplied modules for many floating projects. Their Hi-MO4 series launched last year is compatible with mainstream floating products on the market. The design of bifacial glass modules will guarantee the reliable weather resistance of floating projects, while that of high-power modules with frames can significantly reduce the cost of installation and lower BOS and operation & maintenance costs. PERC and gallium-doped patent technologies further ensure the stable operation and high power generation revenue of projects. (mfo)
