Photovoltaic systems are technologically mature, reliable, economically competitive and sustainable. This paper presents an experimental analysis of the energy performance of a solar plant with mono- and bifacial photovoltaic modules on different types of ground (white sand, white gravel and dark gravel). The solar plant consists of a bifacial photovoltaic system with a nominal power of 6.36 kWp and a monofacial photovoltaic system of 5.52 kWp and is located at the Centre for Science, Technology and Health (CTS) of the Federal University of Santa Catarina (UFSC). The energy performance analysis is based on data measured and collected from the solar plant's monitoring platform and the INMET weather station database. The analysis period runs from February/23 to January/24. Using meteorological data from the INMET, the monthly global solar irradiation on the tilted plane and the clearness index were determined for the city of Araranguá/SC. From the solar plant's electrical data, the yields of the photovoltaic arrays, the performance ratio and the bifacial gain of the photovoltaic systems were determined. The photovoltaic system with bifacial modules showed superior energy performance compared to the photovoltaic system with monofacial modules. The bifacial gain of the bifacial modules on different types of ground was determined and it was found that the average bifacial gain was 9.81%, 8.34% and 4.87% respectively for white sand, white gravel and dark gravel.
