Bifacial panels can also better benefit from solar trackers to follow the sun throughout the day. With tracking, the electricity generated has been shown by one study to increase by 27% over monofacial panels, and by 45% over fixed-tilt bifacial panels.4 Another study with similar results determined

Bifacial vs. Monofacial Solar Panels

Bifacial panels can generate up to 9% more electricity than monofacial panels, according to recent research by the National Renewable Energy Laboratory (NREL), a division of the U.S. Department of Energy.2 As is the case with higher efficiency monofacial panels, this means that fewer panels need to be installed—as well as the associated hardware like panel mounts, inverters, and cables—reducing both hardware costs and labor costs.
