Outdoor degradation rates (DR) of PV modules for ten years were calculated by means of multi reference linear interpolation/extrapolation method (MRLIM), which utilizes many outdoor measured I-V curve data. Transitions of monthly translated I-V curves under the STC, which are created by MRLIM, indicates how PV module degrades. The DR of maximum power (Pm), short circuit current, open circuit voltage, fill factor, and series resistance were calculated from translated I-V curves. As a result, a poly crystalline Si case, annual DR of Pm was calculated as -0.53 %/year. In addition, the accuracy of this method was calculated by comparing with indoor measurement results.
