Experimental Investigation of Energy and Exergy Analysis of Polycrystalline Silicon Photovoltaic Panels
Abstract
Today, the increase in energy conversion costs and energy demand, coupled with the inadequacy of existing resources, necessitates the production of energy with high efficiency and minimal loss. At this stage, efficiency-enhancing applications in energy conversion systems are becoming increasingly important. In this study, photovoltaic systems were operated at inclination angles of 20°, 30°, and 40° under real field conditions, and experimental studies were conducted to determine the inclination angle at which the system operated with higher efficiency in Edirne's climate conditions for August 2025. In the experimental studies, meteorological data, panel temperature, current, and voltage were measured and recorded. The energy and exergy analysis of the system was performed using the experimental data. According to the analysis results, the energy and exergy efficiency of the photovoltaic panel is high at a 30° tilt angle in August. No experimental study has been conducted in the literature examining the energy exergy analysis of photovoltaic panels at different tilt angles for Edirne's climatic conditions. In this respect, the study serves as a model example for Edirne and locations with similar climatic conditions.
