Product Overview

Pre-assembled AL6005-T5 aluminum ground mount solar mounting system for utility-scale and commercial solar farms. Factory pre-assembled for rapid installation with 0-45° adjustable tilt.

The Terra AL is a pre-assembled AL6005-T5 aluminum ground mount solar mounting system for commercial and utility-scale solar farms. Factory preassembly of columns, purlins, and sliding rails means primary components arrive ready to unfold and bolt — dramatically reducing on-site labor and eliminating the need for precise ground preparation. Compatible with ground screw and concrete foundations, the system supports 0–45° tilt in both portrait and landscape orientations across project scales from 256 KW to 32 MW.

Constructed entirely from AL6005-T5 anodized aluminum, the Terra AL delivers superior corrosion resistance for coastal, tropical, and high-humidity environments without the weight penalty of steel. With a 25–30 year design life, 12-year product warranty, and over 70 MW of documented installations across Japan, Indonesia, South Korea, and Europe, the system is proven at scale.

Certified to JIS C 8955:2017, AS/NZS 1170, DIN 1055, and ASCE/SEI 7-05 with design wind ratings up to 60 m/s. Custom structural calculations available for every project to ensure compliance with local building codes.

Frequently Asked Questions

Terra AL's highly-preassembled components allow for quick setup and significantly reduced labor time.
Pre-assembly refers to the process where primary components of the system are assembled at our factory prior to delivery. This means less work for you during installation, as it involves simply unfolding the main structure.
If conditions permit, we recommend using a ground screw foundation. However, if the soil conditions are not favorable, a concrete foundation would be a more suitable option. We strongly advise conducting a soil test prior to installation to determine the most appropriate foundation for your specific circumstances.
If you have an ongoing project with details, please fill out this online inquiry form and we will get back to you shortly.
We provide detailed installation guides, drawings, and dedicated customer support for a seamless experience. The structural calculation is also available for industrial projects.
While the product is designed to last for 25-30 years, we warrant that the Products designed and manufactured by Megawa Solar shall be free from defects in material and workmanship for a period of 12 years.
AL6005-T5 is an aluminum alloy specifically engineered for structural applications. The T5 temper designation indicates the alloy has been artificially aged for optimal strength. This material offers an excellent strength-to-weight ratio, superior corrosion resistance compared to steel, and is 100% recyclable. In the Terra AL ground mount system, AL6005-T5 with anodized surface treatment provides the structural integrity needed for wind loads up to 60 m/s while keeping the system lightweight for efficient installation.
The Terra AL supports a tilt angle range of 0 to 45 degrees, accommodating both low-tilt configurations for tropical regions and steep-tilt setups for higher latitudes. The tilt angle is set during installation based on the project's latitude and energy yield optimization. The adjustable design also accommodates slight terrain variations, ensuring consistent array alignment even on uneven ground.
Yes, the Terra AL is specifically designed for commercial and utility-scale solar farm installations. The system has been deployed on projects ranging from 256 KW to 32 MW, including mega-scale solar farms in Japan, Indonesia, South Korea, and Europe. The pre-assembled design and all-aluminum construction make it particularly efficient for large-scale deployments where installation speed and labor cost reduction are critical.
The Terra AL is engineered and certified to multiple international structural standards: JIS C 8955:2017 (Japan's photovoltaic array design standard), AS/NZS 1170 (Australian/New Zealand structural actions standard), DIN 1055 (German structural loading standard), and ASCE/SEI 7-05 (American minimum design loads standard). Custom structural calculations are provided for each project to ensure compliance with local building codes and site-specific environmental conditions.
