Anti-corrosion measures for photovoltaic power stations in rainy and high-humidity climates

In order to deal with the corrosion problem of the photovoltaic power station's metal structure and brackets in rainy and high-humidity climates, a series of preventive and protective measures need to be taken:
Material selection: Using materials with good corrosion resistance is an important measure to prevent corrosion. For example, the bracket can be made of materials such as galvanized steel, stainless steel or aluminum alloy. These materials have good corrosion resistance and can effectively resist corrosion in humid environments.
Surface treatment: Anti-corrosion treatment of metal surfaces can significantly extend the service life of the structure. Common surface treatment methods include hot-dip galvanizing, spraying anti-corrosion paint or using anti-corrosion coatings. These treatments can form a protective film on the metal surface, blocking the contact of moisture and oxygen and slowing down the corrosion process.
Design Optimization: When designing a photovoltaic power plant, moisture accumulation in the structure should be avoided as much as possible. For example, the design of the bracket should consider the drainage function to avoid rainwater retention. Maintaining appropriate ventilation gaps between supports and photovoltaic modules can promote air circulation, reduce moisture accumulation, and reduce the risk of corrosion.
Installation quality control: During the installation process, the tightness of all bolts, connections and joints should be ensured to prevent moisture from entering the interior. For critical areas, waterproof sealants or fillers can be used to increase the waterproofing effect.
Regular inspection and maintenance: Regular inspection of the metal structure and supports of the photovoltaic power station, especially after the rainy season, should focus on inspection of corrosion-prone parts, such as bolted joints, grounding devices and electrical connections. Once signs of corrosion are found, damaged parts should be cleaned, repaired or replaced in time to prevent further spread of corrosion.
