“…The solar pond experimental model has been shown in the form of a picture, as illustrated in Figure 2. [19][20][21][22] It also depicts the solar pond, as well as its zones and Nanoparticle-enhanced PCM capsules. The thermal sensors illustrated in Figure 2 were used to record the temperature at various depths along the zones of the solar pond.…”

Non-conventional energy is one of the clean energy resources. In this, solar energy is plentiful and contains high exergy among non-conventional energy sources. Thermal energy storage is a method of storing thermal energy by heating a storage material that may subsequently be used for heating or power generating. This study focused on the development of solar ponds for effective solar energy storage. The study depicts the heat fluctuation in a solar pond with phase change material and Nanomaterial. Paraffin wax was used as a phase change material and the performance has been investigated and compared with the addition of nanomaterials such as carbon nanotubes and silver-titanium oxide. The experiment was conducted out on the solar pond without and with phase change material, as well as with carbon nanotubes and silver-titanium oxide inclusion. The experimental results exhibit that the phase change material used to store the majority of solar energy, the temperature difference measured at night for the solar pond with nanoparticle-infused phase change material was minimal. The energy storage capacity of the solar pond increases by 7.8%, 21.8%, and 25% when it is coupled with paraffin wax, silver-titanium oxide/paraffin wax, and carbon nanotubes/paraffin wax. The average temperature variation of the solar pond was observed on the weekly basis by 3°C, 5°C, and 7.5°C when it is coupled with paraffin wax, silver-titanium oxide/paraffin wax, and carbon nanotubes /paraffin wax respectively. It is concluded that compared to simple phase change material, the silver-titanium oxide, and carbon nanotubes have better performance in the storage of thermal energy.

“…Table (8) shows the weather data for the days during which the solar radiation and ambient temperature experiments were conducted. Figure (12) shows the effect of changing mass flow rate on thermal efficiency, total efficiency, and electrical efficiency. It is observed that when the mass flow increases, the thermal efficiency also increases due to the increase in convective heat transfer, where the maximum thermal efficiency reached 33.53% at the highest mass flow of 0.163 kg/sec.…”

“…Forced convection was used to move air over and under the PV panels, increasing the thermal energy of the system that was used for the purpose of drying as well as increasing the electrical energy generated by the panels. Ali et al [12] published a new study on the hybrid system (PV/T) using the solar pond system. A heat exchanger installed under the photovoltaic panels was used for the purpose of cooling the panels in addition to storing water in the storage area.…”

In this article, an experimental study of the single-pass hybrid (PV/T) collector is conducted in the climatic conditions of Fallujah city, where the experimental results are compared with a previous research to validate the results. The effect of changing the angle of inclination of the hybrid collector (PV/T) and its effect on the electrical power in the range (20°-50°) is studied. The optimum angle of the collector is found to be 30°, which gives a maximum electrical power of 58.8 W at average solar radiation of 734.35 W/m 2 . In another experimental study with different air flow rates ranged from 0.04 kg/s to 0163 kg/s, where it is found that the maximum electrical power of 57.66 W at an air flow rate of 0.135 kg/s, while the maximum thermal efficiency reaches 33.53% at an air flow of 0.163 kg/s at average solar radiation of 786 W/m 2 .

“…Different types of photovoltaic (PV) systems, which turn solar power into usable energy, are available. In general, the two major types of PV systems used today can be summarized as PV panels and hybrid photovoltaic thermal (PVT) systems [6]. Solar photovoltaic systems and solar collectors can generate only electrical or thermal energy.…”

The target of the current study was to review and analyze the research activities of previous studies on cooling techniques for thermal photovoltaic (PV) systems using phase-change materials. These materials have the ability to absorb and release certain amounts of potential heat energy by changing their state from phase to phase (solid–liquid) within a small temperature range. These materials have been used to regulate and lower the temperature, increase the efficiency, and extend the life of solar cells. A host of improvements have been made to phase-changing materials through the combined utilization of phase-change materials and fins in addition to nanoscale fluids to enhance electrical efficiency. When using PCMs, the thermal, electrical, and overall efficiency improved by 26.87%, 17.33%, and 40.59%, respectively. The addition of nanomaterials increased phase-change materials’ specific heat capacity and thermal conductivity, thus reducing the plate temperature and increasing the electrical efficiency. It was found that using of nanoparticles together with a microcapsule had better performance in terms of energy efficiency. Studies indicated that variable phase materials were not used because of their high cost and lack of stable operational design. Therefore, the effect of phase-change materials on PV/thermal (PVT) system performance needs further investigation and study.
