Soltec SF7 Bifacial Solar Tracker Attains Bifacial Gain of 15.7%

Soltec has concluded the preparation of its white paper on SF7 Bifacial solar tracker module. The paper presents the results obtained from September 2018 to September 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 existing in the market today: one-in-portrait (1P) and two-in-portrait (2P). Results have shown that individual modules deployed in SF7 Bifacial tracker in 2P configuration exhibited a Bifacial Gain that is 2.1% higher than that of the same modules in 1P configuration.

Besides that, the study 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 study also builds on information provided in Soltec’s previous white paper to better understand the impact of Bifacial Gain factors, with the aim of enhancing knowledge and optimizing 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.
