Description
Positioning solar modules on flat roofs and flat ground without roof penetrations, the IntegraRack IR-05MBDB MultiBallast DB kit offers a 5° south-facing tilt or a 0° raised flat layout. It supports modules up to 34 sq ft, with winds up to 180 mph and snow up to 100 psf.
Key Features
- Dual Configuration: Choose a 5° tilt with a wind spoiler or a 0° raised flat layout from the same kit family.
- Aluminum Construction: Aircraft-grade aluminum base mounts with H module brackets form a rail-free system.
- Ballasted Installation: Standard 32 lb 4 x 8 x 16 in CMU blocks hold the array in place on flat roofs and flat ground.
- High Wind Ratings: Rated up to 160 mph at 5° with the wind spoiler and up to 180 mph in the 0° flat layout, with 32 lb blocks and 3 base mounts.
- Snow Load Rating: Handles up to 100 psf for modules up to 24 sq ft and 65 psf for modules up to 34 sq ft.
Each kit is sold per solar panel. Order one kit per module, plus one extra kit to start each row.
It sits on flat roofs or flat ground, ballasted with 32 lb 4 x 8 x 16 in CMU blocks and 9 x 6 in roof slip sheets under each base.
Ratings are extrapolated from the November 2024 University of Washington Kirsten Wind Tunnel testing and Phoenix National Laboratories mechanical load testing.
