Dirty Panels, Lower Profits: How Clean Solar Panels Boost Efficiency
A thin film of dust can cut solar output by up to 30 percent. Many businesses install panels to save on energy costs, yet they miss a simple step that keeps profits high. Clean panels capture more sunlight, which means more electricity and better returns on investment. How Dirt Affects Solar Panel Performance Solar panels rely on light hitting their surface. Dust, bird droppings, pollen, and pollution form a barrier that blocks sunlight. Next, the panel works harder to generate power but produces less. In some cases, decreased output forces facilities to use grid energy at peak rates, driving costs up. The more layers of grime build up, the worse the effect. Seasonal rains wash some dirt away, but they leave hard water stains and streaks. These marks reduce efficiency over time. That’s why regular cleaning is not optional for businesses that run on solar energy. Common Causes of Panel Soiling Have you seen panels near busy roads or in dusty regions? Traffic ...
