Array STI H250 UH (Dual-row)

Designed to Drive Down LCOE

Dual-Row Solar Tracker

Discover the Array STI H250 UH: our newest dual-row tracker enhanced for maximum flexibility and reliability. Designed for fragmented, difficult terrains and expertly crafted to tackle site constraints—like irregular boundaries, prominent slopes, and field obstructions. Plus, it’s Agri-PV friendly, ideal for dual use with grazing animals, pollinating habitats, and crops.

Its enhanced design is based off the legacy product line of H250 which has a strong reputation and established presence in Europe, South America, and Africa. A proven suite of products, the STI H250 line upholds Array’s stringent standards for durability.​

Always in sync

The H250 UH has an onboard control and communication system that brings row after row of functionality.

  • High operation reliability
  • Configurable alarm management
  • Customizable backtracking algorithm that minimizes shadows
  • Seamless integration with the plant communications system and SCADA with Modbus TCP/IP standard
  • Zigbee® wireless communication system
  • Remote monitoring and predictive maintenance that avoids downtime
  • Commissioning and backtracking tools

It also powers itself

Once it’s set up, the motors power themselves with a little less than 3 feet of solar panels.

Engineered to deliver more with less

The STI H250 UH dual-row solar tracker was designed to deliver a low LCOE through a trailblazing dual-row design. It uses advanced wireless communication technology to synchronize and control a 60-meter long row with a single motor. Its structure powers approximately 60 photovoltaic modules per row in a vertical position (1V). This optimized configuration allows a single motor to move up to 120 modules. That engineering enables one mighty motor to deliver an incredible amount of power while still adapting to virtually any type of layout and terrain. Today more than 200 PV plants employ around 70,000 dual-row trackers.

Product benefits

Installation process

Installation time flies thanks to our simple structure, modular design and low learning curve. We engineered the STI H250 UH to fully assemble without the need for cutting, welding, or drilling. We even supply the assembly tools so that your crews can start turning bolts and stop checking measurements.

In the H250 UH, the driveline is the last component to be mounted making installation seamless & fast, similar to installing a single-row tracker. Compared to other dual-row trackers, this design makes for a speedy installation. We also offer a wide range of foundations that work across virtually any type of terrain while minimizing or removing the need for earth movement.
