Abstract
This article presents the results of degradation studies and performance changes (for 7 years) of solar panels of a solar photovoltaic plant located in the Pap district of the Namangan region of Uzbekistan using the IEC 61724 standard. The solar photovoltaic plant is located in a zone of sharp continental climate, built from polycrystalline photovoltaic panels and has a power of 130 kW. The analysis of monitoring system data showed that the average degradation rate of solar panels is 0.224%/year, which is comparable to the values obtained by the same method for other power plants with similar characteristics. The degradation value is determined from the slope of the annual temperature-adjusted productivity factor. The annual productivity ratio varies from 75.89 to 93.54%, depending on the season, i.e., the value is higher in spring and summer, lower in autumn and winter, with an average value of 87.22%. The average annual changes in the reference and final generation are 4.12 and 3.67 h, respectively.
