Less Land.
More Solar.
SunChord™ by Roll-A-Rack combines solar energy, rainwater harvesting, and a reversible footprint in one low-profile racking system. Manufactured at the project site, it brings more flexibility to farms, constrained parcels, landfills, brownfields, and community-sensitive land.
Energy. Water. Soil.

34% less land for the same solar output in HelioScope modeling vs. conventional fixed-tilt.
95% of rain falling on the array captured and directed for collection.
A ballasted, reversible footprint with no driven posts or ground penetration.
Product benefits, technical details, and the beta pilot offerDesign-build solar racking as a service.
We review the land constraint, design the compact racking layout, and form the steel channel at the project site so the rack is built around the parcel.
Plan around the land take
We review parcel limits, target capacity, row spacing, drainage, and ground conditions before the rack is produced.
Form the rack at the site
A portable roll former converts coil stock into structural channel near the row, reducing long racking loads and enabling field adjustment.
Install with EPC crews
Roll-A-Rack supports layout, on-site forming, and rack delivery while installers place modules with standard field tools.
Sixty seconds: what on-site roll forming looks like
Sites where acres are the constraint.
SunChord is intended for projects where conventional row spacing or site disturbance consumes too much usable land.
Landfills
Capped sites where pile driving may be restricted. Racking sits on graded fill.
Brownfields
Sites with shallow contamination or excavation limits.
Farms
Small farm sites where row spacing affects usable land.
Community parcels
Lower profile, fewer truckloads, and less site disturbance.
Same panels.
Smaller footprint.
HelioScope project modeling shows 34% less land for the same solar output compared with conventional fixed-tilt. Integrated gutters manage rainwater while the compact rows make better use of the parcel.
| Conventional fixed-tilt | SunChord | |
|---|---|---|
| Row spacing | 12 ft reference layout | 15 in |
| Racking arrival | Pre-formed, flatbed | Coil stock, formed on site |
| Ground prep | Driven posts in typical systems | Ballasted, no penetration |
| Site adaptability | Fixed before delivery | Adjusted in the row |
| Modeled land use, same output | Reference layout | 34% less land |
| Landfill / brownfield fit | Site dependent | Designed for constrained sites |
Feet on the ground.
A city-supported install in a Cleveland residential lot. At Hood Honey urban bee farm, the project demonstrated on-site channel production and panel installation with a two-person crew.
Roll-A-Rack selected for Larta Venture Fellows 2026
Roll-A-Rack is part of Larta Institute’s 2026 Venture Fellows cohort, supporting the next stage of pilot planning, field validation, and commercialization for land-efficient solar racking.
