Combines single-post principle of the Sigma I with robust rail technology of Sigma II

West Sacramento – May 30, 2013

Mounting Systems, Inc., the international developer and manufacturer of solar racking systems, presents the new open terrain PV racking system Sigma I XL. The substructure combines the advantages of the Sigma I single-post racking system with the robust Pi-rail technology of the Sigma II. By ramming only one post, Sigma I XL reduces pile-driving time and requires less site improvement and maintenance time than its two-post counterpart. Resembling the Greek letter "Pi", the Pi-rail's consists of a horizontal beam that provides strength and stability with minimal material usage.

Due to improved material use and increased structural force of the Pi-rail, Mounting Systems manufactures the Sigma I XL in both portrait and landscape versions. Both versions rely on the Pi-rail technology and employ a patented attachment method for the respective applications. The Sigma I XL in landscape configuration provides a click-system for assembling the modules quickly, easily and without screws or bolts. Its portrait "brother" utilizes Mounting Systems' patented slot-nut-technology, the Quickstone, for a fast and secure installation.

Susanne Kylla, Director Sales at Mounting Systems, Inc., says: "The Sigma I XL stands out with its simple, functional design and the minimal number of tools needed for installation. Most parts are pre-assembled making this new open terrain product fast to install. This means considerable savings in time and installation costs compared to other systems, especially in large-scale projects." Since the Sigma I XL does not require concrete foundations, the need for site alteration is reduced and reclamation is easy, making the system environmentally friendly. In addition, the system is fully recyclable.
