Follow these simple guidelines for safe and effective cleaning: When to Clean: Avoid cleaning during peak sunlight hours; early morning or late afternoon are ideal to prevent water spots from rapid evaporation. What to Use: Clean water is sufficient; avoid harsh detergents. . We first discuss the drawbacks of unwanted deposits on solar panels in terms of energy production and efficiency. Existing cleaning practices and technologies are then presented with an emphasis on factors such as the size of the facility, location, cost, and available resources. Dust, dirt, pollen, bird droppings, and other debris can reduce energy output by 15–25%, according to the National Renewable. . Philadelphia Solar recommends cleaning during early morning or night when solar radiation is low, and the module is cooler especially in region of hotter region. Why Is Cleaning Important? — A Key Factor for Sustained High Efficiency The power generation efficiency of a PV system heavily depends on the cleanliness of the module surface. Keeping those panels spotless isn't just about aesthetics—it's about protecting your investment and maximizing your renewable energy output. Contamination can reduce the electricity yield by up to 30 percent.
