Impact of Soiling on Solar Panel Efficiency

Studies have shown that soiling can lead to notable decreases in solar panel performance:​

  • Accumulated dust and dirt can reduce solar panel efficiency by up to 7.4% over just a few months without cleaning. ​solaranalytics.com.au
     
  • In areas with high dust or pollen levels, dirty solar panels can experience power capability reductions of up to 30%. ​Wikipedia

Effectiveness of Cleaning

Regular cleaning has been demonstrated to restore and even enhance the performance of solar panels:​

  • The National Renewable Energy Laboratory (NREL) found that mechanical cleaning methods, such as wet brushing, resulted in performance increases ranging from 5% to 11%. ​NREL

  • A study in India reported that a self-cleaning system improved photovoltaic panel efficiency by 18.3% during the summer months. ​MDPI+1solaranalytics.com.au+1
     

Economic Considerations

Economic Considerations

While cleaning incurs costs, the benefits often outweigh the expenses:​

  • For a typical residential solar system in California experiencing a 7% annual soiling loss, the financial impact could amount to approximately $65 per year. ​Solar.com
     
  • Regular maintenance can lead to long-term savings by preserving optimal system performance and extending the lifespan of the panels.
