How Often Should Solar Panels Be Cleaned for Optimal Output?

Determining the right cleaning frequency for your solar rooftop depends on your location, rooftop angle, and surrounding foliage. ### Key Factors Determining Cleaning Frequency 1. **Proximity to Main Roads**: Vehicles create airborne soot and dust that settles daily on nearby panels. 2. **Surrounding Trees & Birds**: Bird droppings act as permanent opaque spots, leading to localized heating (hotspots) that stress solar cells. 3. **Roof Pitch & Slope**: Flat roofs accumulate stagnant rainwater and dirt rings much faster than sloped roofs. ### Choosing the Right Sunvori Care Plan - **Plan 1 (One-Time Wash)**: Ideal after monsoon season or heavy construction work nearby. - **Plan 2 (2 Times a Year)**: Recommended baseline for most residential rooftops in Kerala. - **Plan 3 (3 Times a Year)**: Best value for high-dust areas, commercial setups, or maximized return on energy investment.
