How Dirt Reduces Performance
Obstructs Light: Particles cover the photovoltaic cells, preventing sunlight from being converted into electricity.
Shading Effect: Even a thin layer creates shading, interrupting the electrical flow and cutting production.
Localized Hotspots: Thick spots, like bird droppings, can create resistance, leading to localized overheating and potential damage.
Impact on Energy Production
Significant Losses: Studies and real-world observations show efficiency drops of 10-25% (or more). Extreme cases have shown losses of over 50%.
When to Clean
Every 3-6 Months: A standard recommendation for general maintenance.
