Abstract

This paper aims to study providing electricity and domestic hot water demand for a single-family house in Basra city, south of Iraq. Three systems have been simulated by TRNSYS16 software to determine their thermal and electrical performance: traditional house (without PVT), with the PVT/water-based and with the PVT/0.4%Al2O3 systems. The annual energy consumption, collected energy, auxiliary energy, thermal solar fraction and domestic hot water have been analyzed in long-term simulation. The results show that the use of the PVT/water and the PVT/0.4%Al2O3 systems combined with the house decreased the annual energy consumption by about 43.54% and 52. 33% compared with the traditional house. The results also established that when using the PVT/0.4%Al2O3 system, the collected energy increased by 17.12%, while the auxiliary energy decreased by 31.51% compared with the PVT/water system. It is also concluded that using both the PVT/Al2O3 and the PVT/water systems with the traditional building covered the domestic hot water demand at about 42% to 100%, and 46% to 100% in various months, respectively. Finally, the results highlighted that there is an improvement in the thermal solar fraction of about 14.5% in the case of using the PVT/Al2O3 system compared with the PVT/water) system
