CDG-19B Solar Panel Dust Detection System

The Growing Problem of PV Soiling

Solar panel contamination has emerged as a critical challenge for photovoltaic systems worldwide. Dust, pollen, bird droppings, and industrial pollutants can lower panel efficiency by 15-35% each year. In dry areas, losses can reach 50% between cleanings. This "soiling effect" costs the solar industry billions in lost revenue each year.

Introducing the CDG-19B Smart Soiling Sensor

The CDG-19B Solar Panel Dust Detection System by Coda Sensor represents a breakthrough in PV maintenance technology. This intelligent monitoring solution provides:

✅ Real-time contamination measurement

✅ Data-driven cleaning alerts

✅ Performance loss quantification

✅ ROI optimization for cleaning cycles

How the CDG-19B Works

Advanced Dual-Sensor Technology

The system employs two precision radiometers that measure:

• Clean reference cell (protected from dust)

• Exposed test cell (mimics panel conditions)

By comparing these measurements, the CDG-19B calculates:

• Soiling ratio (0-100%)

• Estimated power loss (in watts)

• Optimal cleaning timeframe

Smart Features

• IP67-rated weatherproof housing

• Modbus RTU (RS485) connectivity

• 5V DC or 24V DC power options

• -40°C to +85°C operating range

Key Benefits for Solar Operators

1. Increase Energy Yield

Reduce soiling losses by 22% on average through timely cleanings

2. Optimize O&M Budgets

Eliminate unnecessary cleaning while preventing excessive buildup

3. Remote Monitoring

Integrates with SCADA systems for fleet-wide soiling analysis

4. Proven ROI

Pays for itself in <6 months for medium-scale solar farms
