“…The results indicated that the multiwalled carbon-silicon carbide hybrid nanofluid exhibited a superior performance compared to the others, achieving 56.55% and 13.85% as its average thermal and electrical efficiencies, respectively. Additionally, 150 W PVTs with different configurations were explored for their potential to enhance the thermal performance (Anurag et al [8]). Specifically, a comparison was made between longitudinal fins with inclined baffles and a free duct without fins for PVT cooling.…”

The advancement of photovoltaic module (PV) enhancer technology shows significant promise due to its rapid growth. Nevertheless, there remains a requirement for ongoing research to refine the evaluation techniques for this technology. In a prior investigation, the concept of the area and cost-effectiveness factor, denoted as FCAE, was introduced to analyze the economic impact of enhancing the PV through techniques such as reflectors or coolers. This metric relates the surface area and manufacturing expenses of a PV enhancer to its capacity for improving the PV output power, aiding in the comparison of different enhancer types. However, this assessment approach is costly, requiring a set of PVs without enhancers to be compared with an equal number of modules fitted with enhancers. This paper introduces a modified version of this metric, termed the modified area and cost-effectiveness factor (FMCAE), along with its minimum value (FMCAE,min), with the aim of reducing the assessment expenses associated with PV enhancers. This modification hinges on knowing the output power from a single solar cell without an enhancer, as well as from a PV with an enhancer containing a known number of solar cells. Additionally, it relies on data regarding the manufacturing cost of the PV enhancer, the cost of one watt of PV power, and the combined surface area of the PV and its enhancer. The equations for computing the total number of solar cells and the associated costs in addition to the expenses cost are also proposed for FCAE and FMCAE. The results of the present study using FMCAE show that there is a proportional relationship between the percentage of solar cell saving and the number of solar cells. As the solar cells increase, the percentage of solar sell saving increases. The findings reveal that utilizing FMCAE leads to a 48.33% increase in the proportion of solar cells saved compared to the existing method. It can be concluded that the proposed method is cost-efficient and holds promise for adoption by PV enhancer designers and manufacturers.

“…In contrast, in ducts with fully transverse fins, partially transverse fins, longitudinal fins with straight baffles, and longitudinal fins with inclined baffles, the temperature was reduced to 62℃, 61℃, 58℃, and 56℃, respectively. When cooling channels with longitudinal fins and inclined baffles are used, energy performance may be raised from 20% to 28% and thermal performance from 12% to 18% [38,39]. According to Figure 6(d), Kumar and Rosen [40] compared the performance of a double-pass PVT air collector with a typical PVT air collector.…”

Solar energy, harnessed from sunlight, can be efficiently converted and transmitted for various applications when coupled with photovoltaic cells and solar heat collectors. A photovoltaic thermal (PVT) collector not only aids in sustaining the power output of the photovoltaic module but also leverages a solar collector to generate heat, thereby facilitating cooling. The performance of PVT systems has been scrutinized by researchers through the implementation of diverse collector designs and fluids. Round and rectangular collector designs prevail as the most extensively utilized models. The materials adopted for collectors in the majority of PVT system evaluations are predominantly copper, with aluminum as an alternative. Several researchers have enhanced the performance of solar systems by integrating collectors with the addition of fins. This review examines numerous studies on PVT systems featuring optimal fins, aiming to concurrently augment both electrical and thermal efficiencies. Furthermore, this research intends to assess a variety of collector designs that have been employed in anticipation of performance improvements.

“…In addition, an improvement in overall energy saving of 7% and 3.9% was achieved when using a fan and a cooling blower, respectively. A numerical study on the effect of forced air cooling for four different configurations of a hybrid PV/T system to achieve higher efficiency in energy performance has been presented by Shrivastava et al 12 The considered configurations are free ducts without fins, ducts with fully transverse fins, partially transverse fins, longitudinal fins with straight baffles, and inclined baffles. The results indicate that when using the forced air cooling technique, there is an improvement in exergy efficiency and energy efficiency by about 8% and 7%, respectively.…”

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.
