According to the Köppen-Geiger climate classification, the Adrar region is a hot desert climate. The performance ratio and several main normalized parameters (system efficiency, capacity factor, and system and total losses) were calculated according to IEC 61,724 standards. Additionally, the assessment and analysis of the degradation rate were limited to a one-year data. The results can be used to improve the prediction of future large-scale photovoltaic plants mounted in hot desert climates and could help in designing, operating and maintaining new grid-connected systems.
