New Roll-A-Rack System Enables Solar Panels On Ballasted Roofs Without Additional Weight

New system uses existing roof ballast to fix solar panels on almost all ballasted roofs

Roll-A-Rack, a Cleveland company developing alternative solar panel racking systems, has developed an innovative new product that allows solar panels to be installed on ballasted membrane roofs without compromising the roof’s structural design.

Ballasted membrane roofs rely on evenly distributed weight for their structural support, but the design often leaves little room for additional loads, such as solar panels. The extra weight of solar energy can easily exceed the physical limit of a roof.

However, Roll-A-Rack has developed an ingenious 12-inch metal channel rack that evenly distributes existing roof ballast while also securing solar panels. The roof ballast, along with the weight of the solar panels, ensures a good fixation of the roof without adding weight and compromising its integrity.

“Roll-A-Rack makes solar energy feasible for almost all ballasted membrane roofs without adding additional load,” said Don Scipione, company founder. “Our system ensures that the weight of the solar panels and the racking system become part of the ballast that holds the roof.

The Roll-A-Rack membrane roof solution is described in a technical poster: “Solar Racking for Ballasted Membrane Roofs” on the Solar Power International Smart Energy Week Digital Poster Program, September 28-29, 2021.

Roll-A-Rack is looking for developers and installers of solar panels to commercialize the installation processes. For more information about Roll-A-Rack or to become a beta tester, visit, email [email protected], or download the information flyer.

Roll-A-Rack and its product development research are funded in part by a grant from the US Department of Energy Solar Energy Technologies Office.
