The preferred system for residential projects
Sigma Pure is a PV ground mount system designed for small- to moderately-sized PV arrays. Sigma Pure uses readily available galvanized steel pipes as support legs and multiple footing options. The steel legs support a strong, corrosion-resistant aluminum and stainless steel superstructure. Preassembled clamps and connection hardware help speed array assembly.
HIGHLY COST EFFECTIVE
Sigma Pure is a highly cost-effective system due to readily available off-the-shelf components from your distributor, making for a robust yet economical PV mounting structure. Cost is further reduced with the incorporation of pre-assembled superstructure components, which minimizes labor. Sigma Pure’s strong, extruded aluminum superstructure helps maximize the span between supports, decreasing the overall number of supports required. Furthermore, Sigma Pure is compatible with earth screws, optimizing Sigma Pure for good terrain adaptability and reducing the need for expensive site grading and modification.
MULTIPLE FOOTING OPTIONS
For further variability and conveniencec, Sigma Pure can be mounted into concrete piers, concrete ballasts, or earth screws as the structural foundation to the superstructure, which can be configured for both landscape and portrait orientations.
ECONOMICAL AND CONVENIENT!
SIMPLE AND EFFICIENT
Sigma Pure implements a strategic combination of engineering innovation, fast procurement, and easy installation that is both economical and long-lasting, resulting to a ground mount system ideal for a wide range of system configurations. All of Sigma Pure’s configurations are PE stamped in solar friendly states to facilitate permitting and approval, providing peace of mind in Sigma Pure’s durability and longevity.
Sigma Pure can be configured into either portrait or landscape orientations. In landscape, modules can be mounted in columns up to four rows high with up to 9 modules per row. In portrait, modules can be two rows high with up to 9 modules per row.
