DPW Solar's two-tier ground mounts are a cost-effective way to create large ground mounted arrays. Two-Tier Ground Mounts are made from 6061-T6 structural aluminum extrusions with a mill finish and have adjustable telescoping back legs. Modules are mounted in portrait orientation 2 rows high and 2 to 5 rows wide. Models are available to hold from 4 to 10 modules (depending on module width). The two-tier mount is a cost-effective way to create large ground mounted arrays. Multiple two-tier mounts may be installed next to each other in an east-west direction. These mounts may also be used as roof mounts if structural and wind load requirements allow. Ground mounts do not include foundations or foundation engineering. Use the Module Series Sizing Chart to determine module series.
