Beware of cleaning photovoltaic panels with dishwashing detergent
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.
Fraunhofer CSP warns some cleaning agents may reduce PV module performance by up to 5.6%
Researchers at the German institute found that some widely used PV cleaning agents can damage anti reflective glass coatings, significantly reducing solar module efficiency. Their tests showed that while some cleaners are safe, others cause visible and permanent coating degradation, highlighting the need for careful selection of cleaning products to avoid long term performance loss.
