Photovoltaic (PV) modules are electrical devices intended for continuous external exposure conditions throughout their lifetime. Highly corrosive humid atmospheres, such as marine environments, can ultimately degrade the performance of a range of PV module components (corrosion of metallic parts due to absorption of salts and other substances, degradation of properties of some non-metallic materials such as protective coatings and plastics). ), which can cause permanent damage that can degrade the function of the component. Temporarily corrosive atmospheres also occur in areas where salt is used during the winter to melt ice on streets and roads. These standards provide protection for other PV modules against corrosion caused by salt spray containing Cl- (NaCl, MgCl2, etc.). It describes a test sequence useful for determining a star. All tests included in this test sequence, except for the bypass diode functionality test, are fully described in KS C IEC 61215, KS C IEC 61646, KS C IEC 62108, KS C IEC 61730-2, and KS C IEC 60068-2-52. there is. They provide a means to evaluate defects that may occur in PV modules when operating under humid atmospheres containing high densities of sodium chloride (NaCL). Depending on the characteristics of the surrounding atmosphere to which the module is exposed in actual operation, several severity tests may be performed
