Abstract: The efficiency of solar panels decreases with high temperatures; so many studies have sought to solve this problem by cooling the photovoltaic panel (PV). One of these methods is coupling a solar air updraft chimney (SC) with a PV Panel and generating a hybrid system (HSC.PV). However, the common feature of this hybrid system is that the PV cooling performance depends mainly on the chimney height, which is an obstacle, especially for large scale. In this study, the updraft air vortex generation technology as an alternative tall chimney was proposed for the first time to improve the performance of photovoltaic cells. The model of the Hybrid Solar Vortex Engine (HSVE.PV) system was designed and developed based on related study outcomes and by a series of process modifications through the commercial CFD. The first experimental results improved the cell's efficiency, which increased by 1.983 %, which caused an increase in the capacity up to 12.978 %. In the next stage, four different models of conical body proposed to be set inside SVE to improve the swirling air updraft strength evaluated by a simulation program. Then, the effect of the conical body was experimentally tested based on comparison and analysis of results, which proved an improvement in the proposed model. This has an impact on the performance of photovoltaic cells, increasing the generated capacity by up to 16.088 % compared to a regular photovoltaic cell.
