Pattern PV Soiling Station
Mounts to Standard PV Racks Including Single Axis Trackers
No Cabling or AC Power Connections Required
Completely Mobile and Installs in Minutes
Recommended to Install One PV PSS per Distinct Soiling Region within the PV System
Cell-Level Pattern Soiling Detection
The PV PSS is designed to measure and model soiling losses at the panel-level while providing the accuracy and simplicity of short-circuit current measurements at the cell-level.

- Measurements from each of 12 PV cells model soiling patterns and relative losses
- Accurately Measures Losses due to Non-uniform Soiling and Active Bypass Diodes
- Redundant Soiling Loss Measurements Ensure Maximum Reliability
- Cell-Level Normalization Ensures Measurement Accuracy and Reliability
- Pattern Soiling Analysis Can Help to Prevent Premature Degradation and Hot Spots as well as Identify Optimal Cleaning Methods
Fully Autonomous, Low Maintenance, Hardware Solution for Maximum Accuracy, Reliability and Mobility
Self Cleaning Reference System
The PV PSS automated reference system ensures reliable and accurate measurements by keeping the reference cell clean and automatically wiping the reference cell before each soiling measurement:
Autonomous Monitoring
Every PV PSS includes all components required to monitor soiling losses and communicate these losses to the Enlighten Energy Soil Monitoring portal or a local DAS:
- Automated, High Precision Measurements
- Self Cleaning Reference System
- On-board GSM modem
- Modbus RS485 Connection
- On-board DAS
- Power Supply and Charge Controller for Battery Connections
