Research from the University of Turku has identified a specific household cleaning agent that can impair solar module performance. The investigation assessed the suitability of common cleaning products for maintaining photovoltaic panels.
The study found that most household cleaners, including glass cleaner and isopropanol, are appropriate for the task and do not negatively affect the light transmittance of module glass. Dishwashing liquid, however, was a notable exception. This product was shown to alter the optical properties of anti-reflective coated solar panel glass.
Scientists observed that while the dishwashing liquid likely does not cause permanent damage to the coating, the transmittance of glass cleaned with it did not recover to its original level, even after the glass was rinsed. They noted that a visually clean surface does not guarantee optimal light transmission.
The experiments involved immersing glass fragments from an unused silicon solar panel in various cleaning solutions for an extended period. In tests on unsoiled glass, all other chemicals improved transmittance, while dishwashing detergent reduced the peak measurement by approximately one percent. When cleaning glass soiled with cultivated algae, the detergent left the transmittance peak nearly four percent lower than samples cleaned with more suitable agents.
Analysis confirmed the antireflective coating itself remained intact after cleaning. The researchers concluded that cleaning impacts the surface evenly and that power output decreases in proportion to the loss in optical transmittance. On average, the transmittance for soiled glass cleaned with dishwashing detergent was about three percent lower compared to glass cleaned with the best-performing agents, suggesting a similar impact on power generation.
The research group has now begun investigating soiling caused by snow accumulation in Nordic conditions, where significant solar radiation coincides with high electricity demand in late spring. This recent work follows other international findings that some widely used photovoltaic cleaning agents can damage anti-reflective coatings, underscoring the importance of product selection to prevent long-term performance loss.
