The type of metal and the atmospheric conditions such as moisture and chlorides can cause serious structural failures in racking and mounting components. Galvanic Corrosion and Protection in Solar PV Installations | Greentech Renewables Skip to main content menu
Is galvanic corrosion a problem in PV installations?
In PV installations, the anode and cathode consist of metals, such as stainless steel, copper and aluminum. Water commonly serves as the electrolyte. Whether galvanic corrosion is a serious problem depends on the potential failure point.
How to choose a corrosion-resistant material for solar cells?
By choosing materials with high inherent corrosion resistance, the vulnerability of solar cell components to corrosion can be significantly reduced . For metallic components, selecting corrosion-resistant metals or alloys, such as stainless steel or corrosion-resistant coatings, can enhance their longevity and performance.
What are the long-term effects of corrosion on PV installations?
For a PV installation, the long-term effects of corrosion can range from unsightly finishes to racking or fastener failure. The more dissimilar the metals, as reflected by their relative position in the galvanic series, the greater the corrosion potential in the galvanic circuit.
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.
How is corrosion characterized in solar cells?
Scanning electron microscopy (SEM) is another valuable tool for characterizing corrosion in solar cells. SEM provides high-resolution images of the surface morphology, allowing for detailed examination of corrosion features, including corrosion products, localized corrosion sites, and material degradation.
