The system was designed for optimum heat transfer. This was achieved by employing high thermal conductivity material such as nanofluids and nano-PCM. Moreover, as Fig. 4 shows, the system utilizes galvanized steel and copper as well. The copper pipes are emerged into a layer of nano-PCM which is stored at the back of PV module. The nanofluid will flow within these copper pipes. To ensure higher heat transfer, glass wool was implemented for thermal insulation. The system consisted of the proposed PV/T collector, a heat exchanger, a nanofluid tank, an expansion tank, the proper sensors, and control devices. In-between the PV and the nano-PCM tank, silicon oil was implemented to avoid air-gaps for better heat transfer. Moreover, the tank covered the whole area on the back of the PV for better cooling and heat transfer. Figure 5 shows the schematic diagram of the combined system.
