PV Anti-Soiling Dashboard
Tabuk / NEOM Region Study
Final Year Project — Fahad Bin Sultan University
Smart Anti-Soiling Strategies for PV Systems
Optimizing cleaning schedules and evaluating anti-soiling coatings for photovoltaic modules in the Tabuk/NEOM desert environment.
Dust Sensitivity Reduction
Cleaning Frequency Reduction
Energy Yield Increase
Total Cost Reduction
Dust Accumulation Over Time
Comparison of dust buildup on uncoated vs. ASC-coated PV modules over 90 days
- Uncoated
- ASC-Coated
Power Loss vs. Dust Density
Loss of power (%) as a function of dust accumulation density (g/m²)
- Uncoated
- ASC-Coated
Key Finding: At 10 g/m² dust density, uncoated panels lose 22.1% power while ASC-coated panels lose only 11.3% — a 50% reduction in dust sensitivity thanks to the anti-soiling coating.
