The impact of sand erosion on mounting structures in large-scale PV plants

Researchers in Spain have tested the erosion resistance of common galvanized coatings using both free-falling sand and forced-air sand-impingement methods. The study found that continuously galvanized steel coatings showed the lowest erosion rates, outperforming HDG and Zn-Al-Mg coatings.A research team led by scientists from Spain's National Center for Metallurgical Research (CENIM-CSIC) has investigated the erosion resistance of commonly used galvanized coatings in large-scale PV mounting systems. "While the degradation of PV panels and the corrosion of structural elements are well-studied, ...
