‘Engineered for Greatness’: The Soltec SF8 Solar Tracker


According to Soltec, manufacturer and supplier of single-axis solar trackers, the bifacial configuration of the new SF8 tracker with multiple drives, which was specially developed for larger solar modules with 72 and 78 cells, can produce up to 8.6% more electricity than other trackers.

“With the TeamTrack system, Soltec has already been able to produce 6 percent more energy,” says José Alfonso Teurel, CTO at Soltec Innovations. “We have now improved this algorithm and adapted it to bifacial modules in order to achieve an additional yield of up to 0.5 percent. This additional bifacial gain from SF8 trackers increases the 2.1 percent of the bifacial gain our bifacial tracker makes when compared to competitive 1-in-portrait configuration trackers. “

The tracker has a new configuration of at least 2 × 60 with four strings of up to 100 kW (and up to six strings in total). In addition, the SF8 contains 5.16% fewer parts per module than the previous generation Soltec trackers, increasing cost efficiency and ease of installation.

A reinforced torque tube with a new, improved geometry and an autonomous self-stowage system contribute to the increased resistance of the tracker to adverse weather conditions. The stiffness of the SF8 is 22% higher than its predecessor, the SF7.

“As a tracker manufacturer, our designs adapt to market trends to provide customers with the best performing trackers,” explains Raúl Morales, CEO of Soltec.

In addition, the SF8 has an innovative wireless system that enables a complete connection between the system and the tracker. The Open Thread system developed by Google helps improve crop protection and damage prevention by accurately predicting weather conditions.

“We believe our SF8 will revolutionize the solar tracking market,” says Morales. “The minimum configuration of 2 × 60 not only reduces installation and maintenance costs, but also provides more energy and increases the overall performance of the photovoltaic system.”
