Test System for dusting solar cell modules | Soiling Tester，Soiling and Abrasion in Photovoltaics Test System
The test system serves laboratory testing according to VDI 3956 (Test method for the dust soiling behaviour of solar energy systems).
This includes tests on the behaviour of glass surfaces under the influence of dusting, changing air humidity and glass temperature and the resulting condensation effects as well as cleaning by wind.
Experiments on other test specimens exposed to these environmental conditions are also possible.
Applications
tests according to VDI 3956
temperature-dependent dusting and cleaning tests of other types of samples
Standard
VDI 3956-1

Principle
The test specimen is mounted on a sample holder in an air lock and then drawn into the preconditioned main chamber. The air lock prevents the dust-containing atmosphere from entering the environment. The desired angle of the specimen is set (up to 60° to the horizontal). The environmental scenarios to be investigated are imitated using the following equipment:
- dusting using generator with dual-positionable nozzle
- temperature control of sample holder: with heating mat/cooling unit
- blowing off the sample using a movable air blade
When air is introduced into the chamber by dust dosing, humidification or sample cleaning, a negative pressure must be present in the chamber to prevent the emission of dust into the atmosphere.
Maintenance Information
Regularly clean the dust generator and chamber interior to ensure consistent test conditions.
Check seals and air-lock components to maintain negative pressure integrity.
Verify airflow velocity, temperature, and humidity sensors periodically.
Inspect compressed air quality to comply with ISO 8573-1 requirements.
Perform routine system calibration according to laboratory quality procedures.
