Researchers in Türkiye have developed a passive anti-soiling coating for PV panels using oleic acid–modified aluminum oxide nanoparticles applied via spray coating. Laboratory and field tests showed ...

Soiling from dust and other particles is one of the biggest causes of PV underperformance worldwide. Image: Kiwa PI Berlin. Soiling-related losses are among the most serious threats to PV performance.

Present systems do not monitor large PV plants on the module level. Yet that is exactly where faults occur, which affect the connection of several solar modules in series, that is, the complete string ...

Researchers in Finland found that dishwashing liquid reduces solar module transmittance and performance, leaving residues even after rinsing. They recommend avoiding its use for cleaning solar panels.
