In this paper, the degradation process of a crystalline silicon photovoltaic module SL100TU-18P (100 W),operated for 14 years under harsh continental climate conditions, is experimentally evaluated. The passport parametersof the module (Uoc, Isc, Umpp, Impp, and Pmax) are compared with the values measured under real operating conditions.The results show that high-intensity solar irradiance, sharp temperature fluctuations, high humidity, and increased dustconcentration have a significant impact on the electrical characteristics of the module. In particular, a pronounceddegradation is observed in the maximum power and current parameters. The experimental studies were conducted atthe Heliopolygon of Tashkent State Technical University, and it was determined that the annual degradation rate of themodule is significantly higher than the passport values specified under ideal conditions
