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

Installs in Minutes and Completely Mobile

Recommended to Install One PSP per Distinct Soiling Profile within the PV System

Cell-Level Pattern Soiling Detection

Every PSS  is a fully autonomous hardware platform which includes all components required to monitor soiling losses and communicate these losses to the Enlighten Energy Soil Monitoring portal:

  • 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 Reliability and Easy Mobility

Self Cleaning Reference System

The 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 Pattern Soiling Station includes all components required to monitor soiling losses and communicate these losses to the Enlighten Energy Soil Monitoring portal:

  • Automated, High Precision Measurements
  • Self Cleaning Reference System
  • On-board GSM modem and Ethernet Port
  • On-board DAS
  • Power Supply and Charge Controller for Battery Connections
