Roll-A-Rack develops solar racking that redirects rainwater

Ohio-based manufacturer Roll-A-Rack has developed a gutter-like sun rack system that collects rain that falls on solar panels.

In order to prevent soil erosion and allow vegetation to grow, on-ground solar projects must allow a certain space between the rows of panels. For Roll-A-Rack, that distance is 11 inches, which reduces the project footprint compared to other ground-mounted projects. The water harvested by the system can be used for irrigation.

The Roll-A-Rack Rain Collection Solution will be presented as a “Collecting Rainwater Falling on Solar Arrays” technical poster at RE+ 2022 from September 17 to 22, 2022 in Anaheim, California.

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, or download the information flyer.

Roll-A-Rack’s development research is funded in part by a grant to Small Business Innovation Research from the US Department of Energy Solar Energy Technologies Office.
