Solar panels convert sunlight into electricity, but dirt can significantly reduce their efficiency. While it seems logical that dust, pollen, and debris would reduce solar panel efficiency, the actual impact varies dramatically based on location, weather patterns, and. . Solar panels represent an effective means of harnessing renewable energy. However, their efficiency can be significantly compromised by dirt. Dirty solar panels can produce up to 25% less energy than clean ones, illustrating the importance of regular maintenance. Over time, dust, debris, bird droppings, and other contaminants collect on the surface of the panels. This dirt reduces light absorption which is crucial. .
