Similar to any solar conversion application into electrical power, the photovoltaic panel performance is suffering from the high temperature and when it is mounted in hot-dry climates. One method to overcome these setbacks is to marry the PV panel with a solar air updraft system, which led to a decline in its temperature by upgrading the air mass flow facing the PV-panel. This paper presents a comprehensive review of the hybrid Photovoltaic-Air Updraft Solar models. The review presents and discusses the compounds and experimental and theoretical studies that were carried out on the existing PV-solar air updraft models. In addition, the paper proposed a new solar air updraft technique by coupling the PV panel with a swirling air generator. The proposed model is simple and more efficient than the conventional solar air updraft design, leading to higher PV panel cooling performance.

In this study, a validated computational simulation is presented to investigate the effect of humidity on the performance prediction of the solar vortex engine system. Data from an experimental model are used to validate the CFD simulation. Three humidity cases are considered: dry air, 40% and 80% humid air. An expansion process with heat addition is taking place inside the vortex generator. When the vortex field continues outside the system, a compression process with heat rejection occurs, eventually bringing the air vortex to be thermal and mechanical equilibrium with the surrounding atmosphere. The change in total energy and the heat transfer rate for both processes, inside the vortex generator and outside the vortex generator, increase with increased humidity in the working fluid. The humidity increases the energy required by the system to generate and maintain the air vortex. Compared to the dry air, the pressure drop at the center of the vortex field decreases by (2-5%) and (4-9%) for the 40% and 80% humid air, respectively. Reduced pressure drop decreases the stability of the air vortex when it is in contact with the atmosphere. The intensity of the air vortex is not affected by the increase in humidity.
