Techno-economic and sensitivity analysis of a building integrated photovoltaic/thermal systems

Abstract

This research explores the potential and feasibility of using photovoltaic/thermal-solar thermal (PVT-ST) systems in hot and moderate weather conditions for the first time. This study examined the performance of a new solar system called PVT module and ST collector in series (PVT-ST). This system can generate both thermal energy at high temperatures and electric power at the same time. The results show that the thermal power increases significantly as the mass flow rate increases. In July, with a mass flow rate of 0.0304 kg/s, the thermal efficiency of ST, PVT-ST, and PVT systems were found to be 86.3%, 79.1%, and 74.2%, respectively.
