- Tree Debris – Leaves and small branches accumulate around panels, gutters, and mounting areas.
- Panel Hot Spots and Minor Cracks – Dirt accumulation can cause uneven heating, reducing efficiency.
- Obstructed Sunlight – Debris or shade from nearby trees reduces solar panel efficiency, making professional cleaning critical.
