ASSESSING THE IMPACT OF TEMPERATURE AND SOILING ON SOLAR PV PANEL EFFICIENCY AND MEASUREMENT PARAMETER ANALYSIS
Abstract
Abstract: In this study, the effect of surface temperature and dust level on the efficiency of solar panels was quantitatively evaluated. The Trina Solar 715W (N-type Bifacial) panel was selected as the object of the study and the experiments were carried out. During the analysis, the real operating temperature (), optical transparency (), and dusting losses () were calculated based on mathematical models and Ber-Lambert's law. The results showed that due to the additional radiation returning from the back surface of the dual module, the total power reached the nominal value (). Due to the low temperature coefficient () of the N-type technology, the temperature power loss when the panel temperature was reached. The proposed set of models allows for numerical modeling of QFES energy indicators
