Nextpower offers the NX Horizon 1P tracker with terrain-following capability and configurable system design
The system includes an independent-row architecture, slew drive with a brushless DC motor, and multiple tracking modes
NX Horizon comes with a 10-year structural warranty and 5-year coverage for motor and electronics
Nextpower (formerly Nextracker), a leading global tracker supplier, participates in the TaiyangNews Market Survey on Solar Trackers 2026 with its NX Horizon tracker, following the delisting of its 2P configuration from the portfolio.
NX Horizon is an independent row 1P tracker, best known for its terrain-following ability. Unlike last year’s fixed 78-120 module range, the 2025 specification lists the Horizon’s module capacity as configurable per module type, string length, and site layout. It supports most utility-scale crystalline-silicon modules and is compatible with First Solar’s S6 and S7 series. The system supports string voltages of 1,000/1,500 V and 2,000 V. It has a GCR of 28% to 50%. A standard tracking range of ±60° is offered, with optional ±75° and ±50° configurations available depending on site requirements. It has an operating temperature range of -40°C to +55°C, for both self-powered and grid-powered systems. The tracker is equipped with a slew gear paired with a brushless DC motor.
The system uses engineered fasteners as specified by the company. Compared to last year’s rating of 225 km/h, the NX Horizon can now withstand wind gusts of up to 240 km/h for 3 seconds. Its bifacial-enhancing features include PV modules elevated above the tubes and a tracker drive system not located under the modules themselves. The vertical separation between the torque tube and solar cells enhances bifacial gain.
It includes intelligent wind stowing with a symmetric damping system, which helps withstand wind, hail, floods, snow, and hurricanes. Foundation options include W6, W8, NX Anchor, and NX Earth Truss. Tracking is governed by an astronomical algorithm, with additional modes including terrain-adaptive, split-cell-optimized, and diffuse-light operation. Communication is handled via Zigbee, and environmental sensing is enabled through the Nextpower Weather Station. Installation includes PE-stamped structural calculations and drawings, along with online training and commissioning. Monitoring and control are delivered via the NX Navigator system-level software, and the tracker is compatible with NX-qualified cleaning systems (see Nextpower Automated Hail Stow Reduces Risk At Utility Solar Projects).
NX Horizon carries a 10-year structural warranty, along with a 5-year coverage for both the motor and electronics. Nextpower has global distribution, highlighting benefits such as independent-row self-powered operation, industry-leading terrain-following capability, wind and hail-resilience, and advanced software functions.
