Coil stock input
The input material is compact steel coil rather than long pre-formed rack members. That shifts transport and staging requirements before any rack member is formed.
Technology
Patented solar racking formed from compact coiled steel
Roll-A-Rack is built around a patented approach to forming solar racking channel from compact coiled steel. Instead of shipping only pre-formed rack members, the system is designed to form structural channel closer to the project site and integrate it into a low-profile solar mounting platform.

Patents and architecture
Patent-backed system architecture.
Roll-A-Rack's confirmed patent references and pending work are organized around a physical racking system: field-formed channel, low-profile ballast behavior, water direction, module attachment, and deployment methods.
Mechanism
Physical sequence and channel functions.
The technical center of the system is the formed channel: how material becomes the rack member, what functions the channel serves, and why that differs from handling only pre-formed racking components.
Roll-formed structural channel
The coil is passed through forming equipment to create a channel section that serves as the primary rack member in the mounting system.
Ballasted low-profile configuration
The formed channel supports a low-profile layout and provides interfaces for ballast where project conditions and engineering requirements allow.
Module attachment interface
Bracket and clamp concepts create the mechanical connection between PV modules and the formed channel without relying on this page as an installation guide.
Water direction and field workflow
The channel geometry can provide a physical path for directing rainwater along the array, while field forming shifts part of the workflow from handling selected pre-formed lengths to controlling channel output near use.
Research
Current and upcoming research.
Roll-A-Rack's current and proposed research work focuses on deployed field testing, agricultural applications, storm-resilient array design, and future construction and maintenance methods.
Current Research
Roll-A-Rack is completing USDA SBIR Phase I research following implementation of the first Roll-A-Rack 4 kW urban farm pilot at Hood Honey, a small bee farm in Cleveland, Ohio.
Current research focuses on:
- Rapid on-site roll forming and installation methods
- Low-profile small farm deployment
- Pollinator-friendly solar applications
- Material handling and logistics optimization
Roll-A-Rack is preparing for Phase II research focused on evaluating how easily Roll-A-Rack arrays can be relocated to support crop rotation and changing agricultural operations.
Roll-A-Rack is currently seeking small and medium-sized farm installers and developers interested in participating as pilot partners.
Upcoming Research
NOAA SBIR Proposal: Hurricane-Resilient Solar Arrays
Roll-A-Rack is pursuing NOAA SBIR funding to further evaluate hurricane-resilient solar array designs.
Wind tunnel testing indicates that Roll-A-Rack's patented low-profile aerodynamic design can significantly reduce uplift forces and remain stable under extreme wind conditions, including Category 5 hurricane-level events with modeled wind speeds up to 250 mph at 30-meter elevation.
Roll-A-Rack is currently in the second round of NOAA proposal review and is seeking installer and developer partners in hurricane-prone regions including:
- Texas
- Louisiana
- Florida
- South Carolina
NSF SBIR Proposal: Drone-Assisted Solar Array Construction and Maintenance
Roll-A-Rack is developing an NSF SBIR research proposal focused on the feasibility of using drones to assist in the construction and maintenance of solar arrays.
Research objectives include:
- Drone-assisted lifting and placement of solar components
- Precision positioning of lightweight roll-formed structural elements
- Automated maintenance operations
- Reducing labor requirements and improving installation safety
Technical diligence
Discuss technical research or pilot partnerships.
Technical review conversations can focus on patent references, current field research, SBIR proposal work, farm pilot partners, or installer and developer partnerships in hurricane-prone regions.
