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.
Business as Usual
As utility-scale solar expands into regions with complex site topographies and rolling hills, conventional tracking systems are limiting. We must go beyond business as usual.
Most tracker systems require longer foundation piles, extensive grading, or a combination of both to accommodate rolling north-south terrain installations, which all adds up to additional costs, potential delays, and environmental concerns, putting projects at risk.
With NX Horizon–XTR
Follow the Grade
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 schedules in check.
- PLAN better by reducing permit risk and improving community acceptance for simpler, faster project approvals.
- BUILD smarter, SAVE money and reduce schedule delays.
- And OPERATE efficiently by minimizing land maintenance and remediation costs.
