6 FAQs about [Photovoltaic bracket anti-corrosion galvanizing]
What is galvanic corrosion in solar PV?
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.

What is the best material for a PV bracket?
This characteristic makes aluminum a suitable choice for PV installations in coastal areas or locations with high humidity. At present, the main anti-corrosion method of the bracket is hot-dip galvanized steel with a thickness of 55-80 μm, and aluminum alloy with anodic oxidation with a thickness of 5-10 μm.
Can solar PV racking corrosion occur?
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?
What is galvanic corrosion?
In the event of galvanic corrosion, a galvanic circuit is created in which the anode (active metal) loses electrons to the cathode (noble metal) when both metals are exposed to an electrolyte (water). The nobility of the metal is the determining factor of corrosion. The more dissimilar metals are, the greater the corrosion potential is.
How to prevent corrosion in PV systems?
The installer has to be careful in choosing the right material. We usually suggest using anodized components to prevent corrosion for the PV systems that are near ocean (salt conditions). Below is a list of best practices for corrosion prevention: Use one material to fabricate electrically isolated systems or components where practical.
What is the best corrosion protection for solar mounting structures?
Your contacts when it comes to high-performance corrosion protection for solar mounting structures: Arne Schreiber, Product Management and Jennifer Schulz, Surface Development. ZM Ecoprotect ® Solar offers several advantages compared to pure zinc coatings.
