Electric parameters determination of solar panelby numeric simulations and laboratory measurements during temperature transient

Abstract

The efficient operation of a solar panel is influenced by several factors. Someof these factors are the intensity and the spectral composition of illumination as well as the ambient temperature together with the temperature and contamination of the solar panel and the atmosphere. This study presents the voltage, amperage, and power change of a commercially available solar panel caused by the temperature transient, by the help of numeric simulations and laboratory measurements. Temperature transient investigations allow us to know more about cooled and non-cooled solar panel behavior, in case of constant intensity of illumination. During the measurements, we have concluded that the temperature increase decreases the maximum power of the solar panel. Compared to the simulation results we experienced good tendential similarity.
