Floating floating photovoltaic refers to the establishment of floating photovoltaic power stations on the waters of ponds, small lakes, reservoirs, and reservoirs to solve the problem of large area of ​​traditional photovoltaic power generation. The hardware components of the floating aquatic photovoltaic power station are mainly photovoltaic panels, junction boxes, inverter equipment, transformers, current collection circuits, and polyethylene floating body platforms. At present, Japan, India, Brazil, and some European countries are all making great efforts to develop floating aquatic photovoltaics. China started late, but it is also embarking on the development of such projects. Let us briefly talk about the advantages and disadvantages of floating-type floating photovoltaics over conventional on-land photovoltaics. Floating floating photovoltaic mainly has the following advantages: 1 Saving land: Built on the water surface, without occupying land resources, it can reduce the cost of land acquisition. 2 Increase power generation: The water body has a cooling effect on photovoltaic modules, which can suppress the rise of temperature on the surface of the module, thereby obtaining higher power generation. According to a comparative analysis of large-scale hydro photovoltaic power stations in Hyogo, Japan, due to the cooling effect of the water surface, the power generation of the panels increased by about 14%. 3 Reducing evaporation and algae propagation: Covering solar panels on the surface of the water can theoretically reduce surface evaporation, inhibit algae reproduction in the water, and help protect water resources. 4 Convenient operation and maintenance: The photovoltaic power station is built in water, which can reduce the pollution of dust to the components, and facilitate the cleaning of the components. At the same time, it is difficult for people and animals to approach the components, which can effectively prevent the destruction of components by personnel and animals. 5 Tourism Benefits: Photovoltaic modules arranged neatly on the vast water surface can be used as a unique scenic spot to become a landscape in the region and bring tourism benefits. 6 Avoid shading of components: Compared to land, the surface of water is relatively open, which can effectively prevent the blockage of components such as mountains and trees, and the solar irradiation area is uniform and the illumination time is long. 7 Reduce the tracking system cost: The components have the same angle and spacing, which facilitates the installation and operation of the solar tracking system. It is not necessary to install a dual-axis tracking system for each panel, which will greatly reduce the cost of the tracking system. 8 Cost savings: No need for component bases and brackets, saving on foundation and rack cost, and saving costs. 9 Convenient for Consuming: Built in a water area close to the village or city, it can be consumed nearby, reducing the adverse factors such as difficulty in grid connection and power limiting, and improving efficiency. Floating aquatic PV also has some disadvantages: 1 High requirements for floating equipment: Floating floating photovoltaics require floating equipment to support photovoltaic panels, and the floating platform must have high requirements for corrosion resistance, low density, frost heaving, wind and wave resistance, longevity, and load carrying capacity. 2 High requirements for site selection: The floating-water photovoltaic electric field site should be selected from a wide area, stable runoff, low wind speed, good lighting conditions, small water level changes, good development conditions, no large-scale shipping, ecologically non-sensitive areas, etc. Water area. 3 There are many uncertainties: high winds, water levels, ice formation and other factors have a great impact on them. At the same time, it is necessary to monitor whether the photovoltaic modules have adverse effects on water quality, fish, and plants in the water. 4 Difficulties in construction: There are many factors to be considered in the construction process. It is difficult to use heavy machinery in water operations for high-efficiency construction, and the processes are more demanding and the construction period is correspondingly increased. There are many jobs that require diving or on board. Work on board should consider balance and safety, and it should not damage facilities such as pool levees.
