Numerous published literatures have given diverse ways of designing photovoltaic (PV) systems including the rooftop mounted PV systems. In this paper, ideas extracted from such studies are employed in a single building rooftop PV power system. Particularly, in this paper, PVSyst simulation software is used for the techno-economic analysis of Building Rooftop Photovoltaic (BRFPV) power system for the Lecture hall at the Faculty of Engineering of Imo State University, Owerri Nigeria was carried out. First, the dimensions of the selected roof were measured and the effective area of the roof for PV installation was determined. PVSyst software was used for the determination of the PV energy generation potential of the BRFPV system along with its other techno-economic performance parameters. The meteorological data used for the simulation was obtained from NASA website. According to the simulation results, the BRFPV system at the Faculty of Engineering of Imo State University had yearly energy output of 2804 KWh/year while the performance ratio was 86% and the unit cost of energy was 69.5 Naira per KWh. Essentially, the BRFPV can satisfy a yearly load demand of 2804 KWh or equivalent daily load demand of 7.69KWh. Finally, the nominal efficiency of the PV module was 5.59%as against the manufacturer’s quoted efficiency of 12.6% at standard test condition. Compared to the exiting literatures, this paper has presented a step by step approach for designing BRFPV using PVSyst software and empirically determined dimensions of the roof of the building. Equally, there are several mathematical and logical approaches that can be used to realize the same results obtained in this paper, however, this paper has presented one of such approaches. Particularly, the paper presented an approach that can be used to determine the effective or operating efficiency of the PV modules based on the energy yield and the PV area.
