A study published in the March 2025 issue of "Nature Energy", based on data from 2800+ weather stations worldwide, systematically quantifies the impact of dust accumulation on PV systems:
Key Findings:
- Global PV annual dust accumulation loses 3.1%–8.4% of power generation
- Calculated based on 2024 global installations, annual losses exceed $50 billion
- Arid regions such as the Middle East, Northwest Africa, and Western China suffer the most severe losses
Automatic Cleaning ROI:
The study calculates that in regions with annual dust losses exceeding 5%, the payback period for deploying automatic cleaning robots is only 2.1 years, far superior to manual cleaning solutions.
