On farms with livestock a substantial amount of ammonia can develop. Over time ammonia salts are formed, which may settle on the PV modules and can have a corrosive effect on them. It is crucial that the glass, frames and connections of the installed solar modules are ammonia resistant and do not deteriorate, especially if the modules are in the vicinity of livestock ventilation systems.
Bisol Group, one of the leading European based producers of PV modules, has proven the high quality of its PV modules by submitting them for the ammonia corrosion test. The test was performed by the German laboratory TÜV Rheinland, who simulated real-world conditions on farms and subjected modules to high concentrations of ammonia, high temperatures and relative humidity.
After eight hours exposure to these extreme conditions, the PV modules were dried for 16 hours in a normal atmosphere. The same cycle was repeated 20 times. After the ammonia exposure, Bisol PV modules were thoroughly inspected. The measurements included relative power measurements, insulation testing, wet leakage current test, ground continuity, bypass diode functional test and visual inspections for corrosion on the frames.
Bisol PV modules passed the test with negligible performance loss. Bisol PV modules are produced entirely in the European Union and are examined several times during the production process. Strict quality control, and various other rigorous tests supported by international certificates confirm that Bisol PV modules are appropriate for installation in different climates areas and under various harsh conditions.
