Photovoltaic modules degradation studies on arrays with a high number of samples from the same manufacturer are not common in scientific literature. We present the results of an extensive experimental campaign on 70 polycrystalline silicon modules after 20 years of outdoor exposure. A comparison between initial and current values of modules electrical parameters is also performed to analyze the effect of degradation mechanisms on module lifetime and module compliance with accelerated test procedures.
