R&D

Phase I research demonstrated Roll-A-Rack technical feasibility

Roll-A-Rack Phase I research completed rack design, wind tunnel pressure testing, prototype installation, and early cost/performance validation.

R&D

DOE SETO SBIR research advanced Roll-A-Rack's solar racking system

Department of Energy SETO SBIR work supported development of Roll-A-Rack's field-formed solar racking system, including design, prototype work, wind testing, and commercialization planning.

Pilot planning

Have a constrained solar site?

Roll-A-Rack is reviewing pilot sites and partner conversations for landfills, brownfields, farms, and community parcels where land take or site disturbance affects the project.
