To receive the certification, the solar panels were completely saturated with a highly alkaline atmosphere (pH grade: nine) of ammonium chloride (NH4Cl) at thirty degrees centigrade for 28 days. Following the test period, the power characteristics and material integrity of the panels were rigorously assessed for potential performance losses and structural problems.
The test is designed to determine whether the solar panels will withstand long-term exposure to ammonia or similar alkaline chemicals, often found in agricultural production facilities.
