PV Pattern Soiling Station

Because the soiling losses of for a given PV array are typically determined by the most soiled panel in a series string, the PV Pattern Soiling Station is designed to easily mount to the ends of the PV arrays where soiling is most prevalent and in this way is representative of the soiling losses of the entire PV array.

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:

Brush gently wipes reference cell clean between measurements

Sealed enclosure protects reference cell between measurements

Moisture sensor ensures reference cell stays dry

Motor control unit automates opening and closing of the reference cell cover

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
