Photovoltaic Thermal (PV/T) collector is a device that can produce electrical energy and thermal energy simultaneously. However, the thermal energy increases the surface temperature of the PV and therefore it may reduce electrical efficiency. To overcome this problem, a finned thermal collector should be joined underneath the PV surface. The aim of this study is to simulate the thermal performance of a PV/T collector by using staggered fins with air as a working fluid. The parameters are varied from 25 to 50 mm in the fin geometry and from 12 to 48 g/s in air mass flow rate, respectively. Furthermore, the heat radiation used was 860 W⁄m2 and Computing Fluid Dynamic (CFD) method was implemented in this research. The results showed that the PV/T surface temperature decreased by 7.04 % for the fin height of 37.5 mm and 11.9 % for the fin height of 50 mm when compared to the fin height of 25 mm. Thus, a greater cooling of the PV/T surface occurs in the fin height of 50 mm due to an increase in the heat transfer area which might absorb more of the unused thermal energy in comparison with others.

“…Each type of cooling has its own advantages and disadvantages. Especially in photovoltaic cooling devices that use a fluid flow system in the channel, there are types of cooling devices with large channel sizes and small channel sizes [24], [25]. There are devices that use the addition of a vortex generator and ones that do without the addition of a vortex generator.…”

A solar panel will be exposed to sunlight when in use, which causes its temperature to increase. The performance of power production will be impacted if the solar panel's temperature conditions are too hot. High-temperature solar panels can reduce the amount of electrical energy generated. To prevent the temperature of the solar panels from rising too much, a cooling system is required. The proposed solution of this research is a cooling system for solar panels that makes use of heat transfer through water. The solar panels tested in this study have a tilt angle of 20 degrees. The cooling device has dimensions of 400 mm length, 278 mm width, and 20 mm height, with a wavy-type vortex generator positioned in the cooling device mounted on the underside of the solar panel. As a result of the heat flux applied to the top surface of the solar panel, it causes an increase in temperature. The resulting voltage and electric current are reduced. Computational simulations were carried out to determine the performance of the type of vortex generator used. At a cooling water flow rate of 200–600 ml/min, heat transfer with a vortex generator type B works optimally.

“…It is also becoming more attractive as solar modules' electricity generation efficiency increases and costs are reduced (Abdo, et al, 2020 A). One of the drawbacks of the PV cell is that the efficiency of its sunlight to electricity conversion does not exceed 15 % in stable operating conditions, while the rest is converted into heat that heats the surface of the PV ( El Kharaz, et al, 2021). When the temperature of the photovoltaic plate increases, the electrical efficiency decreases, and accordingly, its voltage which leads to its degradation over time.…”

Purpose: The drop in photovoltaic energy conversion efficiency under actual operating conditions because of cell temperature increase is a significant challenge to PV adoption and utilization. In this study, the efficiency and effectiveness of using underground water in cooling and cleaning photovoltaics will be practically ascertained in Baghdad-Iraq. Method: The cooling mechanism utilizes copper pipes in a modified spiral flow configuration. This developed system is referred to as Photovoltaic thermal (PV/T). To study the effect of using underground water wells on the performance of the PV system, two wells were drilled four meters apart to prevent the interference of cold well water and hot water from the heat exchanger. The water is drawn from the first well, with a depth of 8.86 m, and the hot water flowing out of the collector is injected into the ground through the second well, which has a depth of 8.43 m. Results: The outcome reveals that relying on a cooling source with a constant - low temperature (21°C) offers excellent cooling for the PV module, compared to an uncooled PV module, by 6°C at 7:00 AM and increased to reach 22°C at 1:00 PM. This reduction in temperature resulted in an average increase in electrical efficiency by 16.7%. The thermal efficiency ranges from 14% at 7:00 AM to 58% at 2:30 PM. Conclusion: The findings suggest that this approach is energy efficient and effective during the summer season.
