Description

The sensor that measures the degree of dirt of the photovoltaic modules

Its 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;
• Optimize module washing schedules;
• Collect pre-construction prospecting data at new sites.

Install the sensor oriented like the PV modules to catch soiling particles. Wash the sensor each time you wash the PV array, to keep the cleanliness identical to that of the modules

• Mars’ innovative optical technology determines the soiling ratio by capturing and analyzing images of dust on the particle collection window;
• User-friendly sensor, simple and robust installation;
• Unlike other optical soiling sensor technologies, it does not require any site-specific calibration;
• Accessories: Cable for PRPMA4100 sensor, L=25 m – CCCFA0500;
• Model code: PRPMA4100.
