A PV soiling monitoring system using reference panels to quantify energy losses and optimise cleaning schedules.
| Datasheet |
Product Description
The SPPM-PV Soiling Monitoring System is designed to measure the impact of dust and dirt on photovoltaic (PV) panel performance, helping operators determine the optimal cleaning schedule.
It uses two reference PV panels (clean and soiled) to directly assess real plant conditions. By applying IEC 61724-1–based algorithms using short-circuit current and temperature measurements, the system calculates a soiling index linked to energy loss.
The system includes a control unit with high electrical isolation and integrates with data loggers such as the METEODATA-4000 for data acquisition, analysis, and remote monitoring. It is suitable for solar farms, performance monitoring, and asset optimisation applications.
Key Features:
- Uses clean and soiled reference PV panels for accurate, site-specific soiling measurement
- Calculates soiling index based on IEC 61724-1 methodology
- Measures short-circuit current (ISC) and panel temperature
- Provides 8 data channels including solar geometry and system status
- High electrical isolation (>1.5 kVAC) for safe and reliable operation
- Compatible with most PV technologies (mono, bifacial, thin film, etc.)
- Integrates with METEODATA-4000 and GeoDataView software
- Supports optimisation of cleaning schedules and energy yield
- Enables SCADA integration via Modbus (through datalogger)
