Analysis of the degradation of amorphous silicon-based modules after 11 years of exposure by means of IEC60891:2021 procedure 3 Piliougine, Michel Sánchez-Friera, Paula Petrone, Giovanni Sánchez-Pacheco, Francisco José Spagnuolo, Giovanni Sidrach-de-Cardona-Ortin, Mariano Silicio The degradation of two amorphous silicon-based photovoltaic (PV) modules, namely, of single junction amorphous silicon (a-Si) and of micromorph tandem (a-Si/μ-Si), after 11 years of exposure in the south of Spain is analyzed. Their I-V curves were measured outdoors to study the changes of the electrical parameters in the course of three different periods: during the initial days of exposure, during the first year, and in the subsequent 10-year period. The translation of the curves to an identical set of operating conditions, which enables a meaningful comparison, was done by the dif ferent correction procedures described in the standard IEC60891:2021, including the procedure 3, which does not require the knowledge of module parameters, whose values are typically not available. The annual power degradation rates over the entire 11-year period are 1.12% for the a-Si module, which is 3.02% for the first year, and 0.98% for the a-Si/μ-Si, which is 2.29% for the initial year 2022-05-06T12:37:13Z 2022-05-06T12:37:13Z 2022-05-06T12:37:13Z 2022 journal article Piliougine, Michel & Sánchez-Friera, Paula & Petrone, Giovanni & Sánchez Pacheco, Francisco & Spagnuolo, Giovanni & Sidrach-de-Cardona, M..
