“…Upon reviewing the recent literature, it was clear that the classification of cooling systems depends on the amount of electrical energy consumed. There are two categories of cooling systems: active systems, which utilize pumps or fans to ensure the cooling fluid movement, and passive systems which operate without the need for secondary energy 8,9 . However, little attention has been given to reducing the power consumption of DC fans.…”

Solar panels' efficiency is highly affected by high‐operating temperatures, especially in semi‐arid and arid regions. This outdoor experimental study aimed to enhance the energy performance of the photovoltaic module by integrating two fans at the outlet of the thermal/photovoltaic hybrid system to ensure forced ventilation. The work novelty depending on achieving low energy consumption by DC fans, so that there is a proportional relationship between the intensity of solar radiation and the energy produced and consumed. The influence of the reduced temperature, operating temperature, and solar radiation intensity on the energy performance of the photovoltaic/thermal hybrid system was analyzed experimentally. The obtained results showed an improvement in electrical and overall efficiency of the new hybrid system by about 4% and 60%, respectively, compared to the conventional photovoltaic module. On the contrary, a decrease in the temperature of the PV module installed in the hybrid system was measured by about 9°C, compared to the conventional photovoltaic module. In addition to the effectiveness of the new technology air cooling proposed at the lowest consumption cost, the thermal energy generated from the proposed system can be invested in solar drying and building applications.

This article proposes a passive cooling system for photovoltaic (PV) panels to achieve a reduction in their temperature. It is known that the cooling of PV panels allows for an increase in the efficiency of photovoltaic conversion. Furthermore, reducing the high temperature of the surfaces of PV panels is also desirable to ensure their long-lasting operation and high efficiency. Photovoltaic panels were modified by adding copper sheets to the bottom side of the panels. Two types of modification of the outer surface of the sheet were investigated experimentally, which differed in surface roughness. One was characterised by the nominal roughness of the copper sheet according to its manufacturer, while the other was enhanced by a system of pins. Numerical simulations, performed using the Simcenter STAR-CCM+ software, version 2020.2.1 Build 15.04.010, helped to describe the geometry of the pins and their role in the resulting reduction in the temperature of the PV panel surface. As a result, modifying a typical PV panel by adding a copper sheet with pins helps to achieve a higher decrease in the temperature of the PV panel. The addition of a copper sheet with a smooth surface to the bare PV panel improved the operating conditions by lowering its surface temperature by approximately 6.5 K but using an enhanced surface with the highest number of pins distributed uniformly on the copper sheet surface resulted in the highest temperature drop up to 12 K. The highest number of pins distributed uniformly on the copper sheet surface resulted in the highest temperature drop in its bottom surface, that is, on average by more than 12 K compared to the surface temperature of the bare PV panel surface. The validation of the numerical calculations was performed on data from the experiments. An analysis of the quality of the numerical mesh was also performed using a method based on the grid convergence index.
