Dust and dirt accumulation, commonly referred to as soiling, can quietly degrade solar PV performance by 2–30% or more, depending on the environment. The SEVEN Portable Soiling Sensor is your compact, high-accuracy tool for on-site soiling loss measurement, enabling fast diagnostics, cleaning optimization, and cost-effective O&M decisions, without fixed installation or complex setup.
What Is a Portable Soiling Sensor?
The SEVEN Portable Soiling Sensor is a handheld or temporarily mounted device that measures the just-in-time (JIT) soiling ratio with optical principle. The JIT soiling loss is critical for:
- Scheduling cleaning based on real data
- Verifying cleaning service effectiveness
- Conducting site comparisons or temporary audits
Unlike permanently mounted soiling stations, SEVEN’s portable model allows flexible use across multiple locations, making it ideal for operations & Maintenance (O&M) teams, EPCs, and auditors.
Key Features of Portable Soiling Sensor
- Real-time soiling measurement: Provides soiling ratio on-site.
- Portable, Lightweight Design: Easily deployable for spot checks across PV fields.
- Built-In Display: View results on-site.
- Battery-Powered Operation: No need for external power during measurements.
Why Use a Portable Soiling Sensor?
- No installation needed; ideal for multiple sites
- Immediate ROI decisions; verify when washing is justified
- Optimize cleaning schedules; balance performance and O&M cost
Typical Applications of Portable Soiling Sensor
- Utility-scale solar plants
- Commercial rooftop arrays
- Third-party O&M service audits
- Field performance inspections
- EPC and QA site visits
- Seasonal or regional soiling studies
SEVEN Portable Soiling Sensor: Fast Data, Better Decisions
Simple to carry, easy to use, and designed for field conditions, the SEVEN Portable Soiling Sensor helps solar professionals quickly assess performance loss due to dust, making it an essential tool for any O&M or quality assurance toolkit.
