Unirac Inc., a provider of infrastructure for solar power systems, has introduced a new version of its product for commercial installations, the ISYS Ground Mount (IGM) racking system. Available now for order, IGM 2.0 is stronger, lighter and installs more quickly than its predecessor, the company says.
This improved version of IGM is constructed of roll-formed C-channel beams rather than the roll-formed and toggle-locked I-beams used for the earlier version of IGM. This design cuts down on material use while maintaining the same structural integrity, according to the company. Manufacturing time can be reduced by as much as 50% through the use of C-channel beams.
The new beams can also be stacked interlocked, saving space and allowing more beams to be transported on fewer trucks. On a typical 1 MW project, the shipping weight of the new IGM rails can be reduced by as much as 14% over that of the earlier design, the company adds.
The Unirac IGM 2.0 allows for the pre-assembly of module columns prior to installation, or the parallel installation of foundations and racking simultaneously. Contractors can build the subassembly or grade land while assembling all modules to Unirac's rails in controlled environments.
