Boost Solar Farm Efficiency with Smart Dust Monitoring

Dust sensors are primarily used in photovoltaic arrays at solar farms and are mounted on the frames of photovoltaic panels. They continuously measure transmission losses caused by contaminants on the glass, thereby calculating the reduction in sunlight reaching the solar panels.

Product Description

How It Works

dust sensor-bgt 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.

Key Features

✅ Optimize cleaning cycles to maximize ROI.
✅ Compact & rugged design with solar-grade materials, waterproof and durable.
✅ Plug & play installation on PV module frames, adaptable to different thicknesses.
✅ Maintenance-free: clean only during panel cleaning.
✅ Strong compatibility: RS485 Modbus, SCADA ready.
✅ 24/7 operation with active light emission (accurate even at night).
✅ Optional add-ons:

GPS positioning with timestamped data
Backside temperature sensor input
Installation angle output (tilt detection + drop-off alarm)

Applications

Utility-scale solar farms in desert and dusty regions.
Industrial & urban PV plants exposed to pollution.
Large solar projects focused on O&M cost reduction and performance optimization.
