NX Horizon-XTR

The industry’s most advanced all-terrain solar tracker

All-Terrain Solution

NX Horizon-XTR™, a new variation of the industry-leading smart solar tracker NX Horizon, breaks the paradigm of “straight-line row” design constraints. XTR conforms to the natural terrain generating a series of benefits such as eliminating cut and fill earthworks, reducing pier lengths, and easing permitting, ultimately accelerating project construction schedule while saving more than time and money.

Industry’s Most Advanced All-terrain tracker

NX Horizon-XTR takes on uneven terrain in stride. By conforming to the ups and downs of varied terrain, NX Horizon-XTR breaks the paradigm of tracker rows requiring installation on a single plane. This minimizes earthwork, reduces foundation steel and keeps construction costs and schedules in check. Watch Video

NX Horizon-XTR: The Key to Unlocking the Value of Challenging Project Sites

Nextracker’s terrain-following solar tracker reduces earthwork, lowers project risk, and simplifies construction on undulating or difficult terrain.

What People are Saying

Donny Gallagher
VP Engineering, SOLV Energy

“We are seeing more and more projects these days having undulating terrain, and Horizon-XTR allows us to build up and over a hill, without having to flatten it out.”

Nick de Vries
SVP of Technology and Asset Management,
Silicon Ranch

“Horizon-XTR allows us to decouple some of the earthwork that used to be mandatory and allows us to build the best structure for the land as it is now.”

Greg Beardsworth
Senior Director, Product Management, Nextracker

“Horizon-XTR breaks the long-time tradition of straight-line rows, unlocking major savings in terms of grading and in terms of foundation pile lengths.”

Alex Roedel
VP of Design and Engineering, Nextracker

“Horizon-XTR has an unbelievable response from our customers because not only does it help them save on earthwork and pile length upfront, it also saves them on labor risk management.”

Going Beyond “Business as Usual”
for Tough Terrain Conditions

As solar power project opportunities expand into new regions and availability of once-ubiquitous flat land becomes increasingly rare, project developers are turning to sites with sloping and undulating terrain.

Uneven terrain presents unique risks for developers, who must employ costly, environmentally impactful grading and increased foundation steel, which can challenge the economics of otherwise attractive solar projects.

The “business as usual” approach to dealing with undulating terrain includes careful selection of tracker-row locations, performing cut-and-fill grading and increasing foundation pile lengths.

While proven, this approach limits system size, increases construction costs and creates schedule risk.

Accuracy of cost and schedule estimates for grading activities are a known challenge, due to the possibility of unexpected soil conditions, weather delays and re-vegetation challenges.

In addition to cost adders and schedule risk during the construction phase, the soil disturbance from earthwork can introduce soil erosion issues over the lifetime of the project.

Follow the Grade
With NX Horizon–XTR

By following the grade on varied terrain, NX Horizon-XTR breaks the paradigm of tracker rows requiring installation on a single plane. This minimizes earthwork, reduces foundation steel and keeps construction costs and keeps schedules in check
