ACCURATE SOILING DATA FOR PV PERFORMANCE MANAGEMENT

Reliable Soiling Monitoring For Solar PV Performance

Soiling on photovoltaic module surfaces is a major factor affecting solar power generation efficiency. Dust and other contaminants reduce optical transmission and limit the amount of sunlight reaching the PV cells.

The solar panel soiling sensor continuously measures optical transmission losses caused by surface contamination and converts the measurement into a soiling ratio, helping operators evaluate the impact of soiling on PV performance.

Designed for installation within new or existing photovoltaic arrays, the system supports continuous monitoring and provides objective data to help determine when module cleaning is required.
