Researchers in Türkiye Develop Oleic Acid Coating to Reduce Soiling on Solar Panels
A team from Türkiye's Konya Technical University has developed a passive anti-soiling coating for solar panels using oleic acid-modified aluminum oxide nanoparticles. Laboratory tests indicated reduced dust accumulation and initial energy output increases, though performance declined under environmental stressors. Optimal results were achieved with a 40-second spray time and 1.5% oleic acid concentration.

Researchers at Konya Technical University in Türkiye have created a passive anti-soiling coating for photovoltaic panels using oleic acid-modified aluminum oxide nanoparticles. The coating was applied via spray technique and tested under laboratory and real-world conditions.
Characterization showed optimal performance with a 40-second spray and 1.5% oleic acid. Field tests revealed coated panels initially produced 0.5-0.8 W more power daily than uncoated ones, but performance declined due to high temperatures and low wind. The study highlighted the coating's potential to enhance energy production in arid regions.
