Photovoltaic module was subjected to PID acceleration test following a DH test in order to clarify the influence of hygrothermal environment on PID for crystalline Si photovoltaic modules. It was confirmed that reduction in maximum power by PID test for the modules with DH test is much larger than that for those without DH test.
