Modules put to the endurance test: Ammonia and salt spray tests

On roofs of farms, the modules can be exposed to high ammonia load, especially if they are near vents or integrated into the roof itself. If, in combination with high humidity, condensation forms, the ammonia can become problematic.

TÜV Rheinland and DLG test the resilience of the modules when exposed to an environment containing ammonia through standardised testing procedures. In order to pass the test, it is crucial that the performance does not excessively decrease, no visible defects occur and that the insulation remains intact even when wet.

For solar modules in coastal areas: Salt spray tests

In coastal areas, the PV modules are excessively exposed to salty air. The salt spray tests according to IEC 61701 expose the modules at a 15-30° angle and 35°C air temperature over a period of 96 hours to spray containing salt in a laboratory environment. Using the following controls (insulation exposed to wet conditions, visual inspection, etc.), corrosion around holes, screw connections and electrical connections are detected.

In this table, you can find an overview of the TRITEC module manufacturers and most important certificates.
