ASTM E1171 Test for Photovoltaic Modules in Cyclic Temperature and Humidity Environments

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E1171 testing. This standard provides procedures for stretching photovoltaic modules in simulated temperature and humidity environments.

ASTM E1171 Test for Photovoltaic Modules in Cyclic Temperature and Humidity Environments

Environmental tests are used to simulate the aging of module materials on an accelerated basis. With these test methods, three separate environmental test procedures are defined: a thermal cycling procedure, a moisture-freezing cycle procedure, and a prolonged moist heat procedure. Electrical bias is used during the thermal cycling procedure to simulate voltages known to occur in field-deployed modules.

These test methods define assembly methods for modules subjected to environmental testing and specify parameters that must be recorded and reported.

These test methods do not determine pass or fail levels. Determining acceptable or unacceptable results is beyond the scope of these test methods.

Any of the individual environmental tests may be performed alone or combined with other environmental or non-environmental tests, or both, in a test sequence. Certain preconditioning tests, such as annealing or light soaking, may also be required or desirable as part of such a sequence. The determination of any such sequencing and preconditioning is beyond the scope of this test method.

These test procedures are time-limited and therefore the results of these tests cannot be used to determine photovoltaic module lifetimes.
