Damp heat Test is performed according to IEC 61215 and IEC 61646. The purpose of this test is\u00a0to determine the ability of the PV module to withstand the effect of long-term penetration of humidity. PV modules are subjected to temperature 85\u00b0C and relative humidity 85 % for 1000 h in the climatic chamber. Damp heat tests, cold tests and temperature & humidity cycling tests combining individual tests are fundamental types of development, quality assurance and reliability testing.
In addition to development tests and reliability tests, the temperature chambers used for these tests are also widely used for heat treatment processes such as temperature aging and humidity control on production lines, and screening tests on test lines. ESPEC’s test facilities can also be used to research and develop production and test technologies. Damp heat, steady state. Describes\u00a0a continuous test at a steady temperature of 40\u00b0C and a relative humidity of 90-95%. The standard test duration is 4 to 56 days. The PV\u00a0Damp Heat Test\u00a0is an accelerated environmental aging test that determines the ability of the solar panel to withstand\u00a0long-term exposure to high temperature and penetration of humidity.\u00a0<\/strong>\u00a0The damp heat test is performed by applying 85\u00b0C \u00b1 2\u00b0C with a relative humidity of 85% for an uninterrupted cycle of 1,000 hours, which is well over 1 month. The to-be-tested solar panel is for this purpose placed in a\u00a0damp heat test chamber\u00a0in which the panel is exposed to these conditions. This test particularly challenges the\u00a0lamination process\u00a0of the PV\u00a0module and the edge sealing from humidity. The\u00a0peel strength\u00a0of the PV\u00a0modules that are laminated according to the traditional lamination process is decisive.\u00a0There are some problems which can be found through Damp Heat Test. Some of them are listed below:-<\/p>
