Ground Systems

Ground-mounted systems are fastened by ramming, drilling or assembling on concrete, with landscape or portrait module orientation. Piles, beams and purlins are Magnelis, PosMAC or black sheet with HDG. Fasteners are stainless A2-70, Geomet or electro-galvanized; clamps are aluminium EN AW 6063-T6. C, U, Z, Sigma C+ and Sigma+ sections are produced with up to 4,000 tons of steel per month for ground optimization, wind and snow resistance and modular expansion.

Carport Systems

Carport systems for commercial or residential use are made of black steel with HDG or static powder coating, sized from site load conditions. Modules may be landscape or portrait and are compatible with varied PV panels. The structure supports EV charging, vehicle protection, waterproofing and cable management channels. Steel supply is up to 4,000 tons per month, supporting up to 100 MWp for ground and carport mounting, with quick installation and optional colours.

Ground-Mount GES Steel Structures

Ground-mount GES tables use driven or concrete-anchored posts with cold-formed galvanized C and U (Sigma, Plus) sections. On soft clay, galvanized C piles are rammed; on rock, posts are anchored to concrete pads. Purlin and post holes are punched to the module size (e.g. 545 W or 600 W) for kit assembly. Telescopic bolted feet and 3-5 cm oval slots take up slope. Single-axis tracker tables are also engineered and fabricated; on hillsides each row post length is calculated for stepped (terrace) layout facing south at the design tilt (e.g. 25-30 degrees).

Ground Fixed Solar Mounting Systems

Ground-fixed solar mounting systems are steel structures for open terrain. SM01 and SM02 are ground-driven systems with 2 vertical or 4 horizontal panels for large and medium-sized terrains. SM03 and SM04 use screw piles on irregular terrains; the screw piles have high-strength properties, can be used any time of the year and are not affected by wind or storm vibration. SM05–SM08 are concrete-base anchored or concrete-embedded column systems for sloped and loose ground. SM09 is a ground-driven single-column system used on hard ground to decrease the number of legs and cost. The high-level engineering design provides assembly and cost advantages.

Solar Twin Vertical System

The Solar Twin Vertical System (MGF-GS-2D) is a steel carrier in which panels are placed in a twin vertical layout for small and large sites. All parts are produced in steel and installed by pile-driving. Material follows EN10025-EN10029, with optional Magnelis coating on the upper group. Layout is vertical, tilt 0-60 degrees, coating ISO EN 1461 hot-dip galvanizing. Warranty is 10 years; compatible with framed and frameless panels. It is used as a ground-driven twin vertical steel system for both field and concrete-base construction.
