The SF7 bifacial tracker provides bifacial gain, which goes from 9.6% in medium albedo conditions (±29,5%) to 15.7% under high albedo conditions (±55%)
Soltec presented its SF7 bifacial tracker, an updated version of the standard SF7, which has become the company’s flagship product.
This bifacial version helped increase the already visible advantages from the standard version. It can capture energy both from the front and the back since it captures the light reflected on the ground under the tracker.
Furthermore, it has higher module mounting, a shadow-free back and wider aisles between the superficial trackers.
SF7 double-wide service aisles between tracker rows increase bifacial reflected albedo capture from the ground and from solar modules of adjacent tracker rows. This feature also results in double the MW-per-pass rate of array washing and vegetation control, reducing O&M costs.

The SF7 bifacial tracker provides bifacial gain, which goes from 9.6% in medium albedo conditions (±29,5%) to 15.7% under high albedo conditions (±55%). This way, the SF7 bifacial tracker offers remarkable economic and performance benefits compared with the main competitors.
These trackers have also evidenced great efficiency when being used on the most common photovoltaic modules in the solar tracker market: 1-in-Portrait (1P) and 2-in-Portrait (2P).
Soltec’s SF7 bifacial trackers with 2P configuration get 2.1% more bifacial gain than the same trackers with a 1P configuration and under the same conditions.
The earnings presented by Soltec come from the Bifacial Tracker Evaluation Center (BiTEC), inaugurated in Livermore (California, U.S.) in 2018. This center is the first in the world created exclusively for bifacial tracker research. It is located in the San Francisco bay area, near Silicon Valley.
BiTEC aims to study the performance of bifacial modules and trackers under different conditions. It analyses their performance based on variables such as albedo, height, distance between modules, and module temperature.
This data was extracted from an exhaustive study carried out throughout twelve months to determine the behavior of these solar trackers and modules during the 4 seasons of the year.
Moreover, the research also intends to determine the best tracker design for implementation in bifacial modules and the tracking equipment that could in any way influence and improve the performance of the modules and the trackers.
This way, Soltec guarantees the design, fabrication, and supply of solar tracker equipment designed and tested to endure extreme conditions and being used under any type of weather.
To date, Soltec has sold more than 270,000 solar trackers worldwide, considerably increasing sales year after year.
In light of this, the Spanish firm managed to position itself as one of the companies with the highest market share in the global PV sector.
Currently, it has hundreds of projects worldwide. Soltec is a leader in Brazil and Colombia. It also has a high market share in Chile and Mexico, as shown by a study on the PV market prepared by Wood Mackenzie.
In recent years, the trend has been to incorporate bifacial technology in more and more projects.
These advances were possible thanks to Soltec’s commitment to having products with the best design and performance.
Total commitment with the client
In addition to this, Soltec is optimizing the standard SF7 Bifacial design on each of its projects. This allows it to increase performance and cut costs.
The company not only offers customers the best possible product, it also provides the best purchase experience and post-sale service.
