No land parcel is perfectly flat, and the value of sites close to fitting that description are growing in both demand and cost.<\/p>\n<p>When developers don\u2019t have to grade land, it can shorten the permitting process, leave native vegetation in place and deter erosion. Skipping grading also means developers can spend less money on site preparation.<\/p>\n<p>\u201cWe heard from our customers, and they needed help. What you hear is, \u2018We want to invest in a certain kind of land, but it doesn\u2019t make sense a lot of times,\u2019\u201d said Erica Brinker, chief commercial officer and head of ESG at Array Technologies. \u201cSome of the very progressive developers globally, they don\u2019t want to disrupt the topography, they don\u2019t want to change the environment.\u201d<\/p>\n<p>In the last year alone, three of the largest single-axis solar tracker manufacturers unveiled proprietary solutions for deploying these solar projects on uneven land. Array Technologies debuted <a href=\"https:\/\/arraytechinc.com\/products\/omnitrack\/\">OmniTrack<\/a>; Nextracker released the <a href=\"https:\/\/www.nextracker.com\/horizon-xtr\/\">NX Horizon-XTR<\/a>; and Nevados Engineering developed its <a href=\"https:\/\/nevados.co\/\">All Terrain Tracker<\/a>.<\/p>\n<p>Each system has different drive mechanisms and row architectures, so their solutions for tackling uneven land differ as well. All systems also promise shorter foundational pile lengths.<\/p>\n<p>Nevados\u2019 All Terrain Tracker has articulating bearings atop foundations that let each panel-bay install at different angles while maintaining rotation. Nextracker\u2019s NX Horizon-XTR has an undulation tolerance of 0.75\u00b0 between piles and a total slope tolerance of 8.5\u00b0.<\/p>\n<p>Array\u2019s DuraTrack single-axis tracker can install on uneven surfaces because it can adjust by 1\u00b0 from pile to pile. Unlike Nevados and Nextracker, Array\u2019s trackers rotate by using inter-row drive lines, so the hurdles to working on undulating land were adjusting pile heights and increasing the number of motors in a block.<\/p>\n<p>\u201cIt\u2019s a mindset shift in the way that you think about the torque tube, because we\u2019re asking the same torque tube to do something different,\u201d Brinker said. \u201cIn a motor block, there\u2019s a lot more torque when you\u2019re moving at different angles instead of a straight line. You\u2019re asking for more capability from those parts.\u201d<\/p>\n<p>Single-axis solar tracker deployment will undoubtedly increase in hillier regions in the coming years thanks to this new built-in slope tolerance. Nextracker has already deployed the NX Horizon-XTR in more than 2 GW of projects, and Array\u2019s OmniTrack is hitting the market in 2023.<\/p>\n<p>\u201cOur customers are telling us that this opens a huge opportunity for them,\u201d Brinker said. \u201cThey haven\u2019t quantified that for us, but there are many places that were once thought impossible to put solar, especially a utility-scale solar site where you need a large amount of land. They\u2019re telling us there\u2019s incredible opportunity to permit more places, especially with the timing of the IRA bill. So developers and investors feel that we have a long enough runway to actually make that investment.\u201d<\/p>\n<p><em>This story is part of SPW\u2019s 2023 Trends in Solar.
