Solar panels can become dirty due to a variety of factors, including:
- Dust and Dirt: Wind can carry dust and dirt particles that settle on the surface of the panels, especially in arid or rural areas.
- Bird Droppings: Birds often perch on solar panels, and their droppings can accumulate, blocking sunlight and reducing efficiency.
- Pollen: In spring and summer, blooming plants release pollen that can coat the panels, leading to decreased performance.
- Leaves and Organic Debris: Trees near solar installations can shed leaves, twigs, and other debris that may fall onto the panels.
- Rain: While rain can help clean panels, it can also leave behind mineral deposits or residue, particularly in areas with hard water.
- Environmental Factors: Pollution, smoke from wildfires, and industrial emissions can contribute to the buildup of grime on panels.
