Soiling losses of for a given PV array are determined by the most soiled cell / panel in a series connected string. The WASPP II (Waterless, Automated, Soiling Pattern, Pod) utilizes cell-level /sub-panel level soiling measurements to determine accurate characterization of non-uniform soiling losses.
The WASPP II is designed to measure soiling losses at the cell / sub-panel level to provide additional reliability, accuracy and insight into soiling losses across the PV plant.
The WASPP II, automated reference cover system ensures reliable and accurate measurements by keeping the reference cell clean and automatically wiping the reference cell before each soiling measurement:
Every WASPP II includes all components required to monitor soiling losses and communicate data to the Enlighten Energy Soil Monitoring portal or a local DAS:
