Solar Panel Dust Monitoring Sensor

This Solar Panel Soiling Monitoring Sensor is a high-sensitivity device designed to measure the impact of dust, dirt, and pollution buildup on solar module performance. Using blue light pollutant detection technology, it accurately calculates soiling ratio (SR)—the reduction in sunlight reaching the panel due to surface contamination.

Easily mounted on the frame of PV modules, this compact device enables real-time data tracking, allowing operations teams to determine exactly when cleaning is needed. With no moving parts and maintenance-free operation (aside from standard surface cleaning), it offers a practical solution for improving energy output and reducing unnecessary labor.

Compliant with IEC 61724-1 standards, this sensor is ideal for multi-point soiling assessment across large PV plants, where environmental conditions vary. Compared to traditional monitoring systems, it offers lower procurement, installation, and upkeep costs, making it an economical tool for solar asset management.

Perfect for utility-scale solar farms, commercial PV systems, and O&M service providers aiming to maximize performance and reduce losses due to panel soiling.
