The Impact of Household Cleaners on Solar Panel Efficiency: A New Study Reveals Surprising Results
Research from the University of Turku in Finland has shed light on how typical household cleaning agents affect the optical clarity of solar panel glass. The findings were shared at the 41st European Photovoltaic Solar Energy Conference and Exhibition, drawing considerable attention within the renewable energy community.
Understanding Solar Panel Performance
To ensure peak performance, solar panels must capture maximal sunlight. Accumulation of dirt and potential damage to the glass cover can hinder this absorption capability. Thus, proper maintenance is vital for effective operation.
The Research Approach
A dedicated team at the University aimed to identify ideal cleaning solutions that would enhance sunlight penetration into solar panels. Their experiments evaluated various cleaning agents commonly used in households.
Key Findings on Cleaning Agents
The results revealed that most traditional cleaners, such as standard glass cleaner and isopropanol, are suitable for maintaining solar panel integrity. However, an unexpected outcome highlighted that dishwashing liquid should be avoided entirely; notably, even unclean surfaces outperformed those treated with this detergent in terms of light transmittance.
“Typically crafted from glass with a specific anti-reflective layer designed not to get damaged during cleaning processes,” explains Kati Miettunen, Professor of Materials Engineering. “We did not examine mechanical cleaning or pressure washing methods here; however, I strongly advise against their use on these systems.”
The Science Behind Optical Performance
Crucially, testing showed no degradation in optical properties when appropriate chemical techniques were applied—dish soap was the sole exception where negative impacts were documented upon its usage.
Surprisingly enough, while dish detergent might appear visually effective after application and rinsing processes did not restore optimal light transmission levels back to pre-cleaning status—indicating an unseen reduction in operational capacity post-cleaning.
A Misleading Cleanliness
“The appearance lacks correlation with efficiency; although washed with detergent might seem clean externally,” noted Research Assistant Julianna Varjopuro. ”Light transmission capabilities are compromised significantly.” This underscores an essential reminder for owners regarding aesthetic cleanliness versus functional efficacy when maintaining their systems.
The Broader Context and Implications
This study conducted by SEMS (Solar Energy Materials and Systems) group emphasizes crucial knowledge concerning proper upkeep strategies for individuals utilizing renewable energy sources across Finland—particularly underlining insights shared through initiatives like RealSolar which strives toward integrating photovoltaic solutions smoothly into national energy frameworks promoting fairness in green transitions.
