Soltec introduces a new independent-row tracker to the survey, while continuing SFOne and SF7 with updated specifications and broader operating ranges
Portfolio highlights include ±60° tracking, 3D backtracking via TeamTrack, Solboost yield gains, and terrain-following capability up to ±15% slopes
All trackers feature wireless communication, multi-mode stow strategies, and certifications under IEC 62817 and UL 3703, with an up to 10-year structural warranty
For the latest TaiyangNews Solar Trackers Market Survey, Soltec has provided data for 3 products, similar to previous edition. However, the company has replaced its SF8 tracker with its latest independent-row system, SFOneX, while continuing to list SF7 and SFOne with updated specifications.
Launched in 2023, SFOneX is the company’s latest independent-row single-axis tracker. The tracker supports a typical row size of 90 modules in a 1P configuration and is compatible with crystalline-silicon modules rated for 1,000, 1,500, or 2,000 V. The structure is built primarily from galvanized steel and supports an array height from 1.3 m to 3.1 m, with a GCR range of 23% to 60%. It offers a ±60° tracking range and operates between -20°C and +55°C, with an optional low-temperature extension down to -40°C. The mechanical design is rated to withstand wind speeds up to 65 m/s and integrates a galloping-free high-tilt stow position, as well as hail, snow, and flood stow modes, validated through wind-tunnel aeroelastic testing.
The system uses a self-locking slew drive powered by a 24 V DC motor and supports both grid-powered and self-powered configurations. It uses Soltec’s TeamTrack control system, which combines astronomical tracking with its Boost algorithm to enable 3D backtracking and optimize capture of diffuse irradiance. The tracker includes sensors for wind, temperature, flood, snow, and hail, with fully wireless communications.
SFOneX additionally incorporates Soltec’s Solboost, which improves the yield up to 8.3%, along with Advanced AgriPV compatibility, wind-tunnel aeroelastic validation, and terrain following for non-constant slopes up to ±15%.
Launched in 2021, SFOne continues as Soltec’s dual-row 1P tracker solution. The system supports all framed module types and now accommodates both self-powered and grid-powered operation. It supports up to 120 modules arranged in a 1P configuration. SFOne is promoted for its adaptability to challenging terrain and harsh climatic conditions, supported by an expanded axis-height range of 1.3 to 3.1 m, suitable for varied topography and AgriPV integration.
The tracker incorporates Soltec’s self-locking slew-drive architecture, which improves structural stability and reduces oscillation under wind loading. It also features the company’s updated TeamTrack system with the Boost algorithm, delivering Solboost yield gains along with 3D backtracking and improved low-light performance. As with SFOneX, SFOne includes hail, snow, and flood stow functionality, wind-tunnel aeroelastic validation, and terrain adaptability.
The SF7 tracker maintains its distinguishing characteristic of eliminating array gaps at pile-mounting locations, thereby enabling full module coverage and improved energy yield. It offers a ±60° tracking range (or reduced on demand) and operates in temperatures from -20°C to +55°C, with an optional low-temperature extension down to -40°C. The tracker accommodates a typical row length of 90 modules mounted in a 2P configuration and is compatible with module voltages of 1,000, 1,500, and 2,000 V. The SF7 tracker now supports an increased axis-height range of 2.2 to 4.3 m, up from last year’s specification of 1.8 to 2.1 m, showing a shift toward higher-clearance installations for improved terrain adaptability and AgriPV deployment. The GCR window has also expanded from 30-50% to 23-60%. SF7 also inherits Solboost. It continues to use slew-drive DC motors and relies on the company’s dynamic wind analysis and high-tilt stow approach to improve stability during extreme weather events. TeamTrack 3D with NREL sun-path data remains standard, optimizing backtracking and minimizing shading under uneven terrain.
According to Soltec, the key strengths of its trackers include reduced piles per MW and high installation tolerances on irregular or steep terrain. Another key point is improved land-use flexibility, enabled by shorter tracker segments, which can carry twice the module count per independent row.
All of the company’s trackers use fully wireless communication, support TMS monitoring, and are compatible with robotic cleaning systems. They are certified to the IEC 62817 and UL 3703 standards. Soltec continues to offer a 10-year warranty on structural components and a 5-year warranty on motors and electronics.
