How It Works
Our dust monitoring system uses a blue light source with multi-frequency modulation to measure transmission losses caused by dust and pollutants on PV glass.Blue Light Source: Ensures long-term stability under UV exposure.
Multi-Frequency Modulation: Filters out interference from sunlight and other sources.
Real-Time Data: Converts soiling ratio (SR) directly into energy loss information.
