It is understood that the humid environment of the water power station is considered when the "herringbone"
floating pv brackets are designed, so, the "herringbone" floating pv brackets are designed to be anticorrosive, safe and reliable, which are the very important factors considered in the bracket selection. The main material of the "herringbone"
floating pv brackets is aluminum alloy and food grade Eps foam, which not only have good corrosion resistance, low density, frost resistance, wind wave resistance and bearing capacity, but also have a long service life of more than 25 years. The comprehensive cost is low, which is 0.1 yuan/W lower than that of the conventional floating pv system.
As an additional cost of floating surface photovoltaic power station, the buoy has been criticized in the process of reducing the cost of per kilowatt hour power. Moreover, the traditional structure of HDPE blow molded buoy is hollow. If there is a small damaged place, the whole buoy will sink due to water leakage.
In view of this, the "herringbone"
floating pv mounting system not only adopts the materials available in the market as a whole and reduces the huge transportation cost of the buoy, but also creatively makes the floating body form of the
floating pv bracket into a filling structure. Even if the buoy is partially damaged, it can still ensure enough buoyancy. The whole photovoltaic floating mounting system would not sink due to water leakage.
In terms of installation methods, the construction methods of floating photovoltaic power station on the water usually include two kinds: one is the shore splicing buoy and installation equipment on the water. The other is the shore operation platform, which will be in the water after the installation of components. The former is often difficult to install due to the limited operation site on the water surface, but as for the latter, the structural performance of the floating mounting system needs to be more challenged. Therefore, the installation mode of the "herringbone" floating bracket needs more performance testing ground installation and it can be integrated into the water, which greatly improves the convenience of installation and reduces the labor cost.
In addition, its floating space can be made full use of for the herringbone floating bracket. The utilization rate of water surface of traditional south facing floating structure is less than 70%, and the capacity of single square array is less than 2MW. The water surface utilization rate of "herringbone" floating structure can reach more than 90%, and the capacity of a single square array can reach an amazing 10MW, which not only reduces the loss and the power generation per unit area, but also reduces the workload of transportation and maintenance. It is conducive to the optimization of photovoltaic system and the reduction of cost.
Under the pressure of affordable access to the Internet, the significance of the floating mounting system in photovoltaic becomes more and more obvious. With the decrease of high-quality sites for the construction of photovoltaic power stations, more and more photovoltaic power stations will be chosen to be built in ponds, lakes, reservoirs and even the ocean.
