Abstract

Porous materials play a crucial role in the energy storage process. The influence of porous media on the performance of the PV/T was investigated by building two experimental units. As well as the utilization of air and water as working materials. The study found that using porous media widens the field of heat transfer and storage throughout the effective time of solar radiation, increasing the hybrid solar collector's thermal and electrical efficiency as well as the air exit temperature. The study found that porous medium can store heat since the difference in temperature between the two models was three hours and 2.8˚C. Using air and water in conjunction with porous medium improves thermal and electrical efficiency. When compared to the model without porous media (glass spheres), the total efficiency improved by 11.36 %, and it was determined that the hybrid solar collector with porous media and air and water usage is more thermally efficient than the other design model. The utilization of a porous media, as well as air and water, resulted in improved electrical efficiency. The porous material retains heat during periods of high solar radiation, lowering the temperature of the solar panels, resulting in a 2.2 % gain in electrical efficiency. as well as making better use of the piping network behind the solar panels Effective cooling of the plate, resulting in increased electrical efficiency. With porous media and without medium, thermal efficiency was (61.33%) and (50.82%), respectively. The overall thermal efficiency rate of the two models increased by 10.51 % in favor of the model with porous medium, which contributed to the regulation. PV temperature is lowered by storing heat during peak solar radiation and minimizing overheating, resulting in increased efficiency. According to the findings, the inclusion of porous material in the second channel raises the output temperature, increasing the system's thermal efficiency.
