Solar tracker manufacturer Soltec is an advocate of the two-in-portrait strategy (covered a bunch here), and it’s doubling down on the concept with its SF7 Tandem tracker. The Tandem will be the first tracker on the market to be linked in a 2-in-portrait (2P) configuration every two rows. The characteristics of this solar tracker combine the best of the 2P trackers with the best of the two-row trackers, while reducing installation and operation costs.
The SF7 Tandem has a cardan that acts as an axle to join both trackers and is installed at a height of 1.8 meters, allowing vehicles to pass between the trackers. In this way, maintenance and cleaning of the power plant can be carried out more quickly, easily, and effectively regardless of weather and climate conditions.
This system includes an asymmetrical backtracking that considers land inclination and characteristics, daytime and season. Soltec’s TeamTrack allows for cost reduction in projects with slopes or non-uniform land. This system does not require maintenance.
With 20% fewer components, 45% less drives and 50% fewer engines in the tracker controller than a 1P tracker, Soltec also says the SF7 Tandem is faster to install.
