Soltec, a 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 a yearlong study at Soltec’s Bifacial Tracker Evaluation Center (BiTEC) in Livermore, California.

BiTEC led a study from September 2018 to September 2019 on 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 Soltec’s SF7 Bifacial tracker in 2P configuration exhibit a bifacial gain that is 2.1% higher than that of the same modules in 1P configuration.

Soltec conducted a yearlong study on bifacial solar tracker gains, specifically testing yields between one-in-portrait and two-in-portrait configurations. 

This document shows that bifacial modules mounted on 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 the information provided in a 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, the company said. All analyses of these factors can be found in the last part of this study, in the fourth Soltec white paper.
