Soiling (PRPMA4100 Sensors)

The PRPMA4100 sensor measures the soiling ratio of photovoltaic modules using innovative Mars optical technology. By taking photographs of the sensor screen at time, it enables an analysis of the deposition of soiling particles on the lens. It’s simple, maintenance-free operation enables users to reduce technician man-hours and produce panel soiling related efficiency loss measurements for PV systems at different scales. The sensor does not require site-specific calibration. By installing the sensor with the same orientation as the PV modules and subjecting it to the same washing operations, the soiling ratio of the modules can be obtained. The sensor is useful for: determining losses caused by soiling for monitoring PV performance; optimizing module washing schedules; determining typical soiling rates for prediction models; and collecting pre-construction prospecting data at new sites.
