  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...

  Under the backdrop of carbon neutrality, the photovoltaic + carport (i.e., solar carport) model is rapidly developing due to its advantages in combining clean energy production with integrated land use. Many solar carport systems currently on the market integrate waterproofing, practicality, and aesthetics, supporting various photovoltaic carport structures such as single-wing, double-wing, Type IV, and Type II. They utilize weather-resistant materials such as hot-dip galvanized steel or zinc-aluminum-magnesium alloys to adapt to different environments. 1. Multiple Waterproofing Mechanisms A typical photovoltaic carport waterproofing design uses a combined structure of "M-shaped main water channel + secondary water channel + waterproof cover + gutter + drainage pipe." Rainwater is collected in the drainage channel and discharged systematically through the gutter, ensuring a dry interior. Integrated Design: The solar photovoltaic modules are integrated with the structure, an...
