Test System for dusting solar cell modules | Soiling Tester
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
