“…Figure 7 shows the V-I and P-V characteristics using fins and without fins. A.M. Elbreki et al demonstrated one of the passive cooling with lapping fins at solar irradiance of 1000 W/m 2 , and the PV module has given better output efficiency of 10.68% at 24.6 °C lower than the ambient temperature of 33 °C (Elbreki et al, 2021). The voltage and current values with a combination of fins and PV panels are tabulated below in Table 5.…”

Recently solar panels are gaining popularity in the field of non-conventional energy sources for generating green and clean electric power. On the negative side, the photovoltaic efficiency is reduced with an increase in ambient temperature. The production of energy is dropped by 0.33% for every degree Celsius above STC. Consequently, the electric power which is generated by the solar panel may not be sufficient to run the load. It is important to realize that in some applications, such as standalone electric vehicles, space for providing an additional solar panel to compensate for the decremented output power may not be feasible. By implementing the cooling arrangements, this excessive heat might be reduced. Several cooling techniques have been implemented, named as active and passive methods. This article presents a review on maximizing the efficiency of the solar panel by utilizing different cooling methods and by integrating TEG with solar panels.

“…Simulation setup This simulation test uses steady-state conditions. In addition, several boundary conditions are given in this stage, including the fluid flow velocity in the channel is 2 m/s (constant) and heat losses at the bottom of the collector are ignored [15]. The computational domain consists of a fluid boundary box (enclosure) of 865 mm x 600 mm x 230 mm which envelope a photovoltaic + heatsink (see Fig.…”

“…In addition [15] also carried out experimental and economic analysis of passive cooling PV modules using planar fins and reflector modules, showing that by using straight fins and lapping fins, the PV modules can be used for 4.2 and 5 years, respectively. Therefore, PV modules that use passive cooling techniques, especially lapping fin designs, are the best choice compared to straight fin designs because they are cheaper in terms of economy.…”

The sun is a renewable energy source that has several advantages such as being easy to obtain, free of pollution, and available in sufficient quantities. The heat energy received by the photovoltaic can cause an increase in surface temperature, resulting in a decrease in electrical efficiency. One of the efforts to increase photovoltaic electrical efficiency is using air cooling, by adding absorber fins or thermal photovoltaic (PV/T). The lapping type fin has superior performance in reducing the temperature of the PV module compared to the linear (conventional) fin type. The purpose of this study was to compare the performance of thermal PV using conventional fins with lapping segmentation fins carried out using the CFD approach using ANSYS Fluent. The simulation test procedures include: making linear fin geometry (conventional), linear lapping and segmentation lapping, conducting mesh quality studies, and determining boundary conditions and modeling parameters. Modeling variations in the direction of airflow 0°, 15°, 30°, 45°, 60°, 75°, and 90°. The numerical simulation results show that the use of segmented lapping fins can reduce the PV surface temperature by 1.79 °C or about 4.11% compared to conventional (linear) lapping in the airflow direction of 90º (parallel to the fins). The results of this study support the use of integrated PV and passive cooling systems to reduce efficiency losses in actual conditions, where there is a multidirectional airflow characteristic, which may not be advantageous for conventional heatsinks.

“…Although the fin surfaces need to be flat and smooth to reduce resistance, they could have different shapes such as transverse ribs, V‐shaped ribs and arc‐shaped to enhance the heat transfer coefficient. Elbreki et al 43 applied a passive cooling method using fins and planar reflector to reduce the module temperature. Their study suggested that the cooling with lapping fins provides the best performance by lowering the module temperature by 24.6°C compared to the reference level while maintaining a panel efficiency of 10.68%.…”

Conventional fossil fuel‐based power generation is one of the main contributors to global environmental pollutions. The rapid depletion of fossil fuel reserves as well as their adverse environmental impact heighten the quest for cleaner and sustainable energy resources to generate electricity. Solar energy is an unlimited and immeasurable source of renewable energy that is used for direct electricity production through the solar PV cell. However, environmental conditions as well as operation and maintenance of the solar PV cell affect the optimum output and substantially impact the energy conversion efficiency, productivity and lifetime, thus affect the economy of power generation. In this study, an investigation about recent works regarding the effect of environmental and operational factors on the performance of solar PV cell is presented. It is found that dust allocation and soiling effect are crucial, along with the humidity and temperature that largely affect the performance of PV module. Additionally, the wind itself carries a significant amount of dust and sand particles, especially in the deserted areas. Deposition of dust in humid conditions forms adhesive, sticky mud on the PV cell and worsens the situation as it reduces the power generation up to 60–70%. This study discusses advanced approaches to mitigate the effects of these factors with their relative merits and challenges. Finally, a guideline is proposed to minimize the effect of different environmental and operational factors to optimize the performance of solar PV cell.
