Soiling Measuring System
Soiling Measuring System
NRG Systems’ next generation Soiling Measurement Kit offers IEC 61724-compliant performance and maximum flexibility to accommodate a range of PV panel types and sizes.The NRG Soiling Measurement Kit provides users with the critical information needed to accurately and reliably quantify the site-specific impacts of soiling caused by dust, snow, and other particles on prospective as well as operating PV projects.
DustVue Solar-Module Soiling Sensor
Campbell Scientific’s, The DustVue calculates soiling loss by comparing the effective irradiance from a test PV module—left to soil at a natural rate—to that of a clean reference PV module. Effective irradiance of each module is calculated in accordance with IEC 60904 by using the measured short-circuit current and back-of-module temperature to calculate effective irradiance. The effective irradiance is then used to determine the real-time soiling ratio. Daily values for the soiling-loss index are also calculated and reported, along with a quality factor for quality control purposes
DustVue 10 Solar-Module Soiling Sensor
Campbell Scientific’s, The DustVue 10 directly measures PV soiling losses using collocated clean and naturally soiled PV reference cells, consistent with the preferred methodology described in IEC 61724-1. Rather than estimating soiling from optical transmission or particulate accumulation proxies, the sensor quantifies the performance impact attributable to contamination on PV-representative surfaces.
DustIQ Soiling Monitoring System
Kipp & Zonen make, DustIQ monitors the loss of light transmission caused by dust, sand, pollen, or any other particles on PV panels using Kipp & Zonen’s new and innovative Optical Soiling Measurement (OSM) technology. The DustIQ has no moving parts and it does not need sunlight to operate. Rather, it uses an internal light source to measures scattered and reflected light that is directly proportional to soiling accumulation on the surface of the DustIQ.
