Standard Test Method for Saltwater Pressure Immersion and Temperature Testing of Photovoltaic Modules for Marine Environments

Importancia y uso:

4.1 The useful life of photovoltaic modules deployed in marine applications (such as floating aids-to-navigation) may depend on the ability to withstand repeated exposure to salt atmosphere, immersion in seawater, and the temperature changes associated with seawater splash falling on modules operating in sunlight. The effects of these exposures may be physical or electrical changes in the module, or both.

4.2 This test method describes a procedure for positioning the test specimen, conducting a cyclical combined pressure, immersion, and temperature (PIT) test, and reporting the results. It also references methods for conducting module electrical performance and insulation integrity tests.

4.3 Data generated by this test method may be used to evaluate and compare the effects of a simulated marine environment on test specimens. This test method requires recording of visible effects as well as electrical performance.

4.3.1 Effects on modules may vary from none to significant changes. Some physical changes in the module may be visible when there are no apparent electrical changes in the module. Similarly, electrical changes may occur with no visible changes in the module.
