Soltec, a leading manufacturer and supplier of single-axis solar trackers and related services in large ground-mount PV projects, has prepared a white paper that presents the results obtained from September of 2018 to September of 2019 at Soltec's Bifacial Tracker Evaluation Center (BiTEC) in Livermore, California.

BiTEC studied the bifacial gain of PV modules deployed in the two most common tracker configurations in the market today: one-in-portrait (1P) and two-in-portrait (2P). Results show that individual modules deployed in SF7 Bifacial tracker in 2P configuration exhibit a Bifacial Gain that is 2.1% higher than that of the same modules in 1P configuration.

Besides that, this document shows that bifacial modules mounted un SF7 Bifacial solar trackers provide 15.7% more Bifacial Gain under high albedo conditions (55.6%) and 9.6% under medium albedo conditions (29.5%).

This document also builds on information provided in previous White Paper to better understand the impact of Bifacial Gain factors, with the aim to enhance knowledge and optimize bifacial module performance.

Bifacial technology is revolutionizing the photovoltaic market and entails changes in the design and behavior of bifacial trackers. All analyzes of these factors can be found in the last part of this study, at the fourth Soltec White Paper.
