Ground Mount Systems

Terra FLEX

The Terra FLEX is a terrain-adaptive ground mount solar mounting system built from AL6005-T5 aluminum and carbon steel, engineered for hillside, sloped, and uneven terrain solar installations. Its east-west and north-south adjustable column design with click-in rail system delivers a 0-30° tilt range and 42 m/s wind resistance for challenging topographies.

Product Overview

Terra FLEX

The Terra FLEX ground mount solar mounting system is purpose-built for hillside, sloped, and uneven terrain where conventional ground mounts cannot perform. Constructed from AL6005-T5 aluminum alloy and carbon steel — a hybrid material combination no competing system offers — the Terra FLEX provides seamless east-west and north-south adjustability through its innovative girder and adjustable column architecture, enabling solar installations on terrain that would otherwise require costly site grading.

Engineered for demanding environments, the system withstands design wind speeds of 42 m/s and supports a 0-30° tilt range across uneven ground profiles. Certified to JIS C 8955:2017, AS/NZS 1170, DIN1055, and ASCE/SEI 7-05, the Terra FLEX meets structural requirements for commercial and utility-scale projects in high-wind regions. Megawa Solar provides a 12-year product warranty with a 25-30 year design life, backed by project-specific structural calculations for every installation.

The click-in clamp and rail system reduces installation time by up to 30% compared to conventional ground mount solar mounting systems. Pre-assembled adjustable columns, purlins, and rails minimize on-site labor and technical complexity — a direct advantage for EPC contractors managing sloped ground projects with tight timelines. Ground screw foundations eliminate concrete work, preserving the terrain and enabling rapid deployment across large hillside arrays.

Why Choose Terra FLEX

Key Advantages

Ultimate Terrain Adaptability

East-west and north-south adjustable column design enables solar installations on hillside, sloped, and uneven terrain without costly site grading. The adjustable girder accommodates variable ground profiles across the entire array.

AL6005-T5 + Carbon Steel Build

Hybrid aluminum-steel construction delivers the corrosion resistance of AL6005-T5 with the structural strength of carbon steel — a material combination unavailable from any competing ground mount system.

Click-In Speed Installation

Revolutionary click-in clamp and rail system reduces installation time by up to 30%. Pre-assembled components minimize on-site labor, cutting project timelines and costs for EPC contractors.

42 m/s Wind Resistance

Structural design verified to JIS C 8955:2017, AS/NZS 1170, DIN1055, and ASCE/SEI 7-05. Suitable for high-wind coastal regions and exposed hillside sites with demanding load requirements.

Adjustable Column System

Variable-height columns compensate for ground elevation changes across the array. North-south adjustment via ground screw height and east-west tilting via adjustable girder base work together for full terrain conformity.

Frequently Asked Questions

The Terra FLEX uses a dual-axis adjustment system. North-south adaptation is achieved by varying the height of ground screw foundations across the slope, while east-west tilting is realized through an adjustable girder and rail base combination. This allows the system to conform to terrain gradients up to 30 degrees without any site grading or earthwork.
The click-in mechanism allows mounting rails and panel clamps to be attached by pressing components together until they lock into place — no specialized tools required for the connection. This reduces installation time by up to 30% compared to conventional bolt-together ground mount systems, directly lowering labor costs for EPC contractors on hillside projects.
The hybrid material approach combines the corrosion resistance and lightweight properties of AL6005-T5 aluminum for rails and clamps with the structural strength of carbon steel for load-bearing columns and girders. This delivers the optimal balance of durability, weight, and cost for terrain-adaptive ground mount installations exposed to high wind and weather.
Megawa provides detailed installation guides, engineering drawings, and dedicated technical support for every Terra FLEX project. For commercial and utility-scale installations, project-specific structural calculations verified to JIS C 8955:2017, AS/NZS 1170, DIN1055, and ASCE/SEI 7-05 are included to ensure full compliance with local building codes.
Standard ground mount systems require flat or graded terrain, adding significant civil works cost on hillside sites. The Terra FLEX eliminates this requirement with its adjustable column and dual-axis girder system, conforming to natural ground contours up to 30 degrees. Ground screw foundations further reduce site preparation by eliminating concrete work, making the system faster and more cost-effective for sloped ground installations.
