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 (PV PSS) 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.
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.
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:
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:
