NX Horizon

NX Horizon


Our Most Amazing Tracker Yet

Our NX Horizon™ is the most advanced single-axis horizontal tracker on the market. Tracking the sun was never more precise, more efficient, and more reliable. Powered by NEXTracker’s self-powered motor drive, each row of solar panels can now be built with significantly less steel and can be optimized for wider rotation angles. As a result, you will maximize your yield, pay less for operations and maintenance (O&M) and reduce the impact on the environment significantly.

Breakthrough Technology

Perfectly Balanced, Perfectly Engineered


We designed a mechanically balanced system that has no overturning moment at the core of the NX Horizon tracker. This allows us to bring down the number of piers needed for one row of solar panels by up to one third. The energy required to move the array is reduced as well and can be easily handled by one self-powered motor unit for each row. As a result, the rows can be a lot longer, featuring up to 90 solar panels mounted in portrait orientation.

A Better Angle

120-Degree Tracking for Higher Yield


Our NX Horizon rotates the solar panels up to 120 degrees (+/- 60 degrees), allowing for a higher energy yield of up to 2%. In case of a severe weather event, the rows can be moved into stowing position in less than 2 minutes. 

Less Maintenance

Every Row Deserves Freedom of Expression

Once installed, our NX Horizon tracker is easy to service. Because the rows are not linked with a drive shaft, maintenance vehicles can drive through the arrays freely. Plus, module cleaning and vegetation management becomes effortless and fast. Each motor is powered by its own dedicated solar panel (with integrated battery backup), making external power cables obsolete. As soon as the wireless controller is plugged in, tracking begins. Each controller has an integrated inclinometer, and can measure each row individually, sending its data through a wireless mesh network. This way we can ensure that the fleet of trackers is performing as it should, any time, all the time.

Lower Installation Costs

Quick Set-up Thanks to Patented Design


Our NX Horizon tracker needs less steel than conventional trackers, allowing for quicker installation. You won’t need drive shafts or extra cabling to power the trackers, speeding the process up even further. NX Horizon is self-grounded, so you won’t have to pay costs and labor for installing grounding washers, braided straps, bare copper wire, and grounding rods. Furthermore, zero welding is required. Our patented fasteners make mounting the panels quick and easy. What’s more, these fasteners must be removed with special tools, providing theft deterrence. The fasteners are designed to hold their tensile strength indefinitely, so you won’t have to waste time and money checking and re-torquing these connections.


Tested and Bankable

We at NEXTracker combine decades of experience with solar trackers, having installed 3 GW solar capacity and counting. Our products have been vetted by independent engineering firms and selected by major solar developers and banks worldwide.

Rising Profits

Make More with Less

Our NX Horizon is designed to be simpler, smarter, and yield more with less to raise your profits. We take our work—and our customers—very seriously. Our commitment to quality ensures trackers of the highest efficiency and productivity and the best economic value. We at NEXTracker have a legacy of performance you can bank on.
