Roll-A-Rack debuting low-profile, manufactured-on-site solar racking

Roll-A-Rack, a developer of patented on-site-manufactured solar racking systems, will introduce SunChord at RE+ 2026 in Las Vegas. SunChord is a low-profile, ground-mounted solar racking system designed to use less land than conventional fixed-tilt racking or trackers. It consists of gutter channels and clamp brackets that attach to solar panels, assembled using Roll-A-Rack’s 'snap-slide-secure' system. The company highlights SunChord’s potential for agrivoltaic applications, land-constrained sites, brownfields, and areas where ground disturbance must be minimized.

SunChord was developed with support from the U.S. Department of Energy’s Integrated Energy Systems Office and the USDA National Institute of Food and Agriculture. Roll-A-Rack claims an array using SunChord can capture 95% of rainwater that falls on it, redirecting it via racking channels. The system is assembled on-site using a roll-forming device similar to producing roof-edge gutters, reducing transportation needs and installation complexity.

Roll-A-Rack states SunChord reflects a vision of combining solar energy production with rainwater harvesting and soil conservation. The company sees the system as a solution for sites where conventional solar approaches are impractical. SunChord is designed to harmonize solar energy generation with environmental considerations, offering a multi-purpose ground-mounted solution.

Roll-A-Rack holds two issued U.S. patents, a pending patent application, wind-tunnel ratings, and UL 2703 certification for SunChord. The company plans to supply SunChord for up to five pilot projects and invites EPCs and developers to contact [email protected] for inquiries.
