The Second Batch of Leading PV Projects Are Mostly Floating Plants


The second batch of photovoltaic "leaders" projects on water surface are mostly solar floating pv plants.

Due to its advantages like land saving and high power generation, photovoltaic power station on water surface has gradually attracted the attention of the industry, but its construction mode is quite different from that of ground photovoltaic power station. How to construct solar pv power station safely and efficiently, select equipment and explore high-income operation mode have become the key to the development of photovoltaic power station on water surface at this stage.

As a member of the "leader" project, "photovoltaic on water surface" has attracted a lot of attention. "At present, there are two types of surface photovoltaic power plants, one is floating type, the other is pile driving fixed type." Chunqiu Wu, technical director of Northman Energy Technology (Beijing) Co., Ltd., introduced that the second batch of photovoltaic "leader" projects on water surface are mostly floating water photovoltaic power plants on water surface at the second leader plan water surface photovoltaic power plant exchange conference and water surface photovoltaic power plant design and equipment selection seminar.

Floating photovoltaic plants on water surface has obvious advantages. According to Fuqin Xiao, deputy general manager of the increasingly popular floating photovoltaic power station on water surface, the floating photovoltaic power station on water surface can use coal subsidence area, landscape lake, reservoir, fish pond, sewage treatment pool, near sea water area and other places so as to save a large part of land resources. And the natural "water-cooled" cooling effect of the water surface is good. The data provided by the solar floater shows that, under the same conditions, the power generation of surface photovoltaic is increased by more than 10% compared with that of the ground solar project. In addition, the floating photovoltaic power station on water surface has the advantages of short construction period, water protection, convenient operation and maintenance, and broad market prospect.

In this regard, Fuqin Xiao provided relevant cases and data at the meeting, from which we can see the advantages of floating photovoltaic power station on water surface. For example, when the 18000 KW floating photovoltaic power station on water surface of Guqiao in Huainan city and a 3000 KW ground photovoltaic power station also in Huainan city have the same solar module and inclination, the power generation of the floating photovoltaic power station on water surface is 13% higher than that of the ground power station. When the 48000 KW floating photovoltaic power station on water surface of Panyang in Huainan, city and the ground power station in the same area are converted into the same installed capacity. The generating capacity of the floating photovoltaic power station on water surface is 11% higher than that of the ground power generation.
 
Solar Floating PV Plants on Water Surface
 
Although the floating photovoltaic power station on water surface seems to be worthy of investment construction, the construction methods of the surface power station and the ground power station are quite different, resulting in many construction units taking a detour. How to construct photovoltaic power station on water surface safely and efficiently has become a key question for the industry at this stage.

Bingqing Yuan, general manager assistant of Three Gorges New Energy East China Branch, said that due to the relatively special floating photovoltaic power station on water surface, certain conditions must be met before construction. First of all, the special construction scheme of floating photovoltaic power station on water surface is required, and the main resources input can be started only when the construction conditions are met. Secondly, technical exchanges with construction personnel and safety training shall be conducted before construction. Finally, special emergency rescue scheme shall be provided in case of danger.

Bingqing Yuan pointed out that some floating photovoltaic power station on water surfaces will be constructed in mining subsidence areas, and geological exploration must be paid attention to in these projects. First of all, it is necessary to entrust a third-party professional organization to carry out the current situation and forecast assessment on the geological disaster risk and foundation stability of booster station, photovoltaic field area, collector line path and transmission line path, so as to provide guidance for the project exploration and design. Secondly, it is necessary to do a good job in the terrain exploration under the water surface, and clean up the underwater obstacles before the implementation of the project to ensure the floating body. It will not be scratched and stabbed by the obstacles below. Finally, according to the project booster station, power collection line and transmission engineering geological conditions, entrust a qualified unit to carry out regular settlement observation on the equipment foundation and line tower foundation of the booster station, find out the settlement risk in time, propose a reasonable rectification plan, and improve the safety and stability of the power station.
