Spain-based independent power producer (IPP) Matrix Renewables is deploying Terafab V2, an automated solar construction platform developed by US-based Terabase Energy, at part of its 457 MW Tormes Solar project in Navarro County, Texas. California-based Solv Energy is serving as an engineering, procurement and construction (EPC) contractor on the project.

Terafab V2 combines robotic assembly, AI-assisted quality inspection and autonomous vehicles to streamline module assembly and transportation, shifting labor-intensive construction activities from the solar field to an automated production line installed on-site.

According to Matrix Renewables, PV modules and structural components are delivered to the on-site assembly line, where robotic equipment mounts the modules onto tracker torque tubes. The completed assemblies then pass through an integrated quality inspection system before being transported to their installation locations.

The modular “factory” is designed for rapid deployment and relocation within a construction site. Terabase says the latest version can be moved and set up in approximately four hours, allowing the assembly line to be repositioned as construction progresses.

Following inspection, robotic equipment loads the completed assemblies onto autonomous vehicles, known as rovers, which transport them to designated locations in the solar field. Workers then unload the assemblies and install them onto prepositioned tracker supports.

Terafab V2 incorporates a manufacturing execution system (MES) to coordinate assembly operations, material flows, quality inspections and transportation.

The platform also integrates construction planning, inventory management and logistics software with a digital twin of the project site. AI-assisted tools support workflow optimization and the coordination of automated equipment.

The system’s modular architecture allows multiple assembly lines to operate at a single project, increasing production capacity according to construction requirements.
