PV soiling monitoring

Product catalog summary

Introduction
The document introduces the DustIQ, a maintenance-free sensor designed to measure the soiling of photovoltaic (PV) panels using Optical Soiling Measurement (OSM) technology. This innovative solution provides insights into power loss due to soiling and helps determine optimal cleaning schedules.

Key Features

Patented technology with no moving parts, eliminating the need for regular cleaning.
Small panel size (990 x 160 mm) made with standard solar industry materials.
Flexible mounting options to fit various locations on solar arrays.
Measures soiling ratio from 100% (clean) to 50%.
Upgradeable with a PV back panel temperature sensor.
Cost-effective, allowing for multiple measurement points.

Advantages Over Alternatives

Completely passive operation, aligning with plant cleaning schedules.
24/7 measurements with a 1-minute interval.
Multiple sensors provide more reliable data than spot-measurement solutions.
Easy integration and installation within solar arrays.

Specifications

Soiling ratio measurement accuracy: ±1% for 90-100%, ±2% for 80-90%, ±5% for 50-80%.
Stability: Auto-calibrating, better than ±1% of full scale per year.
Connections: RS485 Modbus® to host, daisy chain to next device or PV panel temp sensor.
Voltage range: 10 to 30 VDC.
Current range: 70 to 200 mA.
Power consumption: < 2 Watt.
Operating temperature: -20 to +60 °C.
Glass type: Standard PV panel glass with all coatings and laminates.
Instrument dimensions: 990 x 160 x 40 mm.
Instrument weight: 4 kg.
Optional PV panel temperature sensor: -20 to +100 °C, ±1 °C.

Conclusion
The DustIQ sensor offers a breakthrough in PV soiling monitoring by providing a maintenance-free, accurate, and cost-effective solution that integrates seamlessly with existing solar array systems.
