The double pass solar air heater or DPSAH is a device that is integrated with the solar air heater in order to facilitate the transfer of heart energy from one part of the device to another part of the device so that the heart's energy can be transferred efficiently. Solar air heaters with just one pass are said to have a lesser impact on the generation of thermal energy since they lose out on the energy during the transfer process and, as a result, they generate less thermal energy. On the other hand, DPSAH exhibits a superior thermal efficiency, as this is the result of doubling the area of heat transfer, which is attributed to its energy-efficient design that allows it to achieve better thermal efficiency. The absorber plate located behind the collector of a DPSAH helps in the collection of solar energy by absorbing the light from the sun. There are many situations where a part such as this will be painted black in order to increase the absorption of solar energy, as this colour has a direct impact on the generation of a higher absorption of solar energy. It is intended that as part of the study, the use of recycled materials will be observed in the construction of the absorber plate, as well as the efficiency that is generated from the use of such materials. It should be noted that the majority of absorber materials which are usually used for this application are semiconductors or dyes, which can come in both organic and inorganic forms.
