What's the best place to put the ballast?

Depending on the panels used and the size of the screen you may have to place the ballast on one or more locations on the stacking base truss. Please consult the ROE Ballast calculator.

The calculator has a graphic showing the locations where to place the ballast. Please always contact the ROE support teams or a structural engineer when in doubt.
