Abstract

The research aimed to investigate the performance and economics of using bifacial PV modules on a model building's roof. The bifacial PV modules used in the study were monocrystalline, half-cut cell type, with a power rating of 430 W per panel. The study was conducted on a white painted concrete surface, and the panel's height was adjusted to 0.50, 1.00, and 1.50 m, while the installation angle was adjusted to 15, 18, and 21°, respectively. The study found that at a panel height of 1.50 m and an installation angle of 15°, a bifacial PV module produced a maximum power of 424.88 W with a power generation efficiency of 21.82 %. Additionally, the study derived a predictive power correlation equation to forecast the electric power production throughout the year based on experimental data. The study further investigated the case of installing 124 bifacial PV panels on the roof of Zone A of Kanchanaphisek King Rama 9th Sports Center Building Center, Maejo University, using the correlation equation to predict the electricity production. The system was found to produce 130,479.36 kWh/year of electricity with an average system performance (performance ratio) of 1.15. The total investment required for the installation was 1,890,699.50 baht, and the payback period was 3.95 years, with a net present value of 1,601,144.48 baht and an internal rate of return of 16.26 %.
