With the life expectancy of a large solar power installation being 25-50 years, why should you use hot dip galvanized steel, which will last 75 years or more even driven below ground, for posts? It can be tempting to avoid the initial cost of galvanizing by using
The life of a solar PV system may be seriously effected by galvanic corrosion. The type of metal and the atmospheric conditions such as moisture and chlorides can cause serious structural failures in racking and mounting components.

Here are its primary applications: Construction: Roofing, wall cladding, gutters, and structural components often rely on galvanized sheets for their corrosion resistance and durability. Automotive Industry: Manufacturers use it for body panels, frames, and parts to enhance lifespan and prevent rust.
Moreover, galvanized sheet metal has self-healing properties. If the zinc coating is scratched or damaged, the exposed steel is still protected. The surrounding zinc can react with air and moisture to form a protective layer of zinc salts, effectively sealing the exposed area and preventing further corrosion.
Since zinc is more reactive than steel, it corrodes first when exposed to the environment, effectively protecting the base metal from damage. This ensures that the steel beneath remains intact and free from rust. Moreover, galvanized sheet metal has self-healing properties.
Yes, galvanized sheet metal can be painted, but surface preparation is essential. Cleaning the surface, removing oils, and applying a zinc-compatible primer ensure proper adhesion and a long-lasting finish. 6.
The metals in solar PV racking and mounting systems can be faced with corrosion if wrong metals are used together. The life of a solar PV system is 25 years, therefore system installers must target a similar life span for the racking materials. How does galvanic corrosion occur?
