Overcoming Dense Geology & Mountain Weather
Deploying high-performance solar infrastructure across variable terrain requires a relentless commitment to structural integrity, engineering precision, and adaptive field execution. The CO-125 Two Rivers Community Solar Farm stands as a benchmark for commercial and utility-scale solar construction in Northern Colorado. Facing dense subsurface geology and severe Rocky Mountain spring weather shifts, Sunstall delivered a fully commissioned 2.507 MW single-axis tracker system—prioritizing uncompromised quality, mechanical resilience, and long-term asset reliability.
The seamless integration of heavy machinery, robotic automation, specialized field crews, and structural hardware formed the operational backbone of the site’s successful build. All-terrain telehandlers, hydraulic pile-driving rigs, and skid steers executed bulk material distribution and primary earthwork, while advanced robotic units assisted with high-precision tasks like automated structural torquing. Operating in direct harmony with this mechanized fleet, Sunstall’s skilled field crew directed GPS layout geometry, executed complex pile remediation, and managed the systematic assembly of OMCO tracker components and PV modules. This unified coordination between cutting-edge technology, heavy iron, and experienced human craft delivered high-throughput execution, uncompromising safety, and flawless structural quality across the entire array.

Next-Gen Automation Meets Field Execution
To streamline tracker assembly and ensure rigorous quality control, Sunstall partnered with RoboForce to support structural torquing across the installation. By integrating RoboForce’s specialized torquing technology alongside Sunstall’s field team, the crew achieved rapid, repeatable torque verification across all structural hardware and tracker table connections. This strategic collaboration accelerated the mechanical completion schedule while guaranteeing strict compliance with manufacturer torque specifications and engineering tolerance standards.
Every Challenge not challenging enough
The Two Rivers build proved that high subsurface refusal rates and extreme spring weather variability can be successfully managed through pre-planned engineering contingencies, disciplined logistics, and the accurate procurement and deployment of labor, machinery, and structural hardware. This resulted in a signed Project Completion Form and a fully operational 2.507 MW single-axis tracker asset delivered on schedule.
