How to choose anti-corrosion measures for photovoltaic brackets in highly corrosive coastal environments?
Photovoltaic support structures are the "skeleton" of a photovoltaic power station, supporting the modules and withstanding wind and temperature changes. Once the support structure is corroded and damaged, the module angles are prone to shift, power generation efficiency decreases, and it may even lead to safety accidents. Photovoltaic power stations are located in various environments, including coastal areas with high salt spray, highly polluted industrial areas, and humid regions, where metal support structures constantly face the challenge of oxidation and corrosion. Coastal environments are the most severe. The sodium chloride content in inland atmospheres is about 0.8 mg/m ² , while in marine environments it can reach 12.4~60 mg/m ² . High concentrations of salt spray can accelerate metal corrosion by 4 to 5 times compared to inland areas. Furthermore, the salt and chloride ions in seawater accelerate electrochemical corrosion; salt spray, humid air, and ultraviolet...
