Performance Enhancement of Bifacial PV Modules on Horizontal Single-Axis Trackers in Desert Environments

Year: 2025

Type: article

Abstract: The adoption of bifacial photovoltaic (PV) modules has grown significantly due to their potential for higher energy yield. However, their real-world performance under outdoor conditions remains insufficiently explored. This study analyzes the energy gains of bifacial PV modules in a horizontally tracked power plant in the Atacama Desert, Chile, comparing a conventional single-axis tracker with an optimized tracker designed for bifacial performance. Results show that bifacial modules on conventional trackers achieve ∼5% higher energy production, while those on optimized trackers reach up to 6.1%, emphasizing the role of tracker design in maximizing bifacial PV efficiency.
