Spanish solar tracker manufacturer Soltec has launched 4×4, a new foundation option for its SFOne range of trackers that aims to improve their flexibility.

These new foundations allow the trackers to be installed on steeper terrain. Trackers built with the 4×4 “functionality package” can be installed on north-south and east-west slopes with consistent gradients as high as 15%, and on slopes with non-constant gradients of up to 20%.

The foundation option is designed for use with the company’s SFOne range of trackers, a dual-row single-axis solar tracker that uses 72- and 78-cell modules, larger sizes of products that have become increasingly common in the solar sector. The company has already deployed these trackers at a number of projects, including three projects owned by oil and gas major Repsol in Spain, and the new foundation option will help improve the performance of this range of products.

Soltec also noted that the 4×4 option benefits from “customisable software” for the SFOne range of trackers, which collects data on the pile driving method used to install the trackers. This data can then be used to develop new pile driving processes, to optimise construction operations, and Soltec expects this process to help reduce project installation costs.

The news follows a number of positive developments for Soltec. Earlier this year, the company posted record-setting revenue for a first quarter, and last month, Soltec launched a new floating tracker for use on inland bodies of water. The company’s chief strategy and innovation officer, Eduardo de San Nicolás, described to PV Tech Premium how the “Flotus” tracker was based on naval design principles to ensure its robustness in floating applications.

Understanding PV module supply to the European market in 2026. PV ModuleTech Europe 2025 is a two-day conference that tackles these challenges directly, with an agenda that addresses all aspects of module supplier selection; product availability, technology offerings, traceability of supply-chain, factory auditing, module testing and reliability, and company bankability.
10 March 2026
Frankfurt, Germany
The conference will gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing out to 2030 and beyond.
