“…They found that the addition of Al 2 O 3 nanoparticles showed the greatest potential to improve the thermal energy capacity of nanocomposite PCMs. This was consistent with the study of Nada et al. (2018) about thermal efficiency of integrated PV module with parrafin wax (pure PCM) and parrafin wax/Al 2 O 3 .…”

“…Conversion of solar energy into electricity directly using a photovoltaic (PV) is reduced due to reductions in the open circuit voltage as solar cell temperatures increase (Nada et al., 2018; Brinkworth et al., 1997). The operating temperature of a typical PV panel in full sun is generally around 60 °C, leading to reductions in the efficiency of approximately 0.5% per degree of temperature Celsius (Luque and Hegedus, 2003).…”

In this study, a micro-encapsulated phase change material (PCM) was composed of sugarcane wax−Al 2 O 3 composite as the core material and gelatin−gum Arabic as the polymer shell materials prepared by complex coacervation. The thermal behavior of solar panels integrated with this encapsulated PCM (EPCM) was investigated. The heat storage-dissipation performance and thermal stability of the sugarcane wax−based composite PCM layer with the heat capacity of 2.86 J/g·°C was influenced by its thickness. Increasing the composite PCM layer thickness from 4 mm to 7 mm could lower the module's front-facing glass temperature by 4% resulting in enhanced the photovoltaic power generation by 12% at the peak, because of the temperature storage ability of the composite PCM. Moreover, the thermal conductivity of the microencapsulated sugarcane wax was calculated using a steady-state one-dimensional energy balance equation. The thermal conductivities estimated across the composite PCM layer depth were found to be temperature dependent. A nonlinear regression of the power law thermal conductivity model gave a good agreement with the observed EPCM-surface temperatures.

“…Finally, the complication attributed to utilizing the two-step method; which is also a problem for the end-user. Another area of interest is the charging and discharging process and how it will affect the panel after sunset as some temperature will remain stored (Chaichan et al 2016;Chaichan and Kazem, 2015;Colla et al 2017;Nada et al 2018). A summary of research works from the recent literature is provided in Table 1.…”

“…Nada and El‐nagar investigated the performance of the PV module with various configurations such as, free standing, building integrated, PV‐PCM and Al 2 O 3 nanoparticles with PCM to enhance the performance of the PV modules 21 . Nada et al 16 studied the temperature regulation of PV module by integrating PCM and PCM/Al 2 O 3 nanoparticles compound. It was reported that the module temperature dropped by 8.1°C and 10.6°C, and an increase in the conversion efficiency was noted by 5.7% and 13.2%, respectively.…”

The work presents the method to increase the electrical efficiency and power output of photovoltaic (PV) panel with the use of phase change material (PCM). CaCl 2 .6H 2 O-Fe 3 Cl 2 .6H 2 O eutectic has a suitable melting point and high latent heat for temperature regulation of PV panel. The work has been focused on the experimental setup and simulation heat extraction from the PV panel with the use of ANSYS software. A modification of copper indium diselenide (CIS) PV module from Solar Frontier (SF170-S) was made with a eutectic mixture (70:30) of calcium chloride hexahydrate (70%) and iron (III) chloride hexahydrate phase change material. The cell temperature of the PV panel with and without PCM was measured and compared for two typical days. The simulation of the PV-PCM systems comprising both PV panels was performed using ANSYS (fluent) software, followed by the comparison of the results actual experimental data. The experimental results show that the maximum temperature difference on the surface of PV panel without PCM was 9 C higher than that on the panel with PCM in a period of 1 day. Referring to experimental results, the calculation of the maximum and average increase of power gain was made for PV-PCM panel. Final results show that the electricity production of PV-PCM panel was higher for 96.55 Whr in a particular day of experimentation.
