Roll-A-Rack Engineering Videos Debut At Solar Power International (SPI) 2020

Videos demonstrate capabilities of new roll-formed racking system

Roll-A-Rack, a faster, lower-cost, ballasted solar-racking solution, will unveil its first portable, roll-forming machine in October at its virtual SPI 2020 showroom. Like seamless rain gutters, which are cut to length on each installation site by a portable roll-forming machine, Roll-A-Rack produces custom solar racking on site and on demand. The new system simplifies the solar-racking supply chain, eliminates waste and speeds installation time.


The rack, aerodynamically engineered to minimize wind uplift, was tested in the atmospheric boundary layer wind tunnel of the independent testing lab, CPP Wind Engineering. A video (click here) illustrates ballast calculations as wind speeds increase from zero to 200 mph across a ground-based solar array. The results show ballast is needed only at the corners and edges of the array.

Roll-A-Rack was designed to be roll-formed on site, yet sturdy enough to withstand snow loads and wind uplift. A second video (click here) shows finite element analysis (FEA) simulations. FEA is a method of calculating how roll-a-rack would respond to snow or wind by calculations on a 3D computer-aided design model.

Roll-A-Rack is seeking 10 developers or solar installers to help refine the installation processes. For more information about becoming a beta tester, visit roll-a-rack.com., email beta@roll-a-rack.com., or download the informational flyer.

Roll-A-Rack product development research is funded in part by a grant from the U.S. Department of Energy Solar Energy Technologies Office. Click here to view our SPI 2020 conference technical poster.
