Most ground-mounted solar power systems today use aluminum mounting structures. While nearly all manufacturers are now based in China, not all products are created equal. At a glance, these mounting systems might look similar, but quality, durability, and structural integrity can differ greatly depending on the production standards.

If your solar installation is expected to operate efficiently for over 20 years, it is essential to select a reliable and precisely manufactured racking system.

Why Factory Quality Matters

Some buyers may focus only on pricing. However, extremely cheap aluminum frames may hide lower-quality materials or poor processing, risking the safety and lifespan of the entire system. At Firstsolar, we conduct on-site inspections and only work with high-standard production facilities under OEM agreements to guarantee performance and reliability.

🏭 Factory Interior

Here is a glimpse into our Firstsolar factory. Unlike many manufacturing sites that may appear cluttered, our facility is neat, streamlined, and professionally managed—reflecting our commitment to quality.

🔩 Aluminum Rod Manufacturing

Step 1: In-House Melting & Casting

Unlike typical factories that purchase ready-made aluminum rods, Firstsolar owns its own smelting furnace, ensuring full control over materials and consistency.

Aluminum is melted and poured into molds
Cast into high-purity aluminum rods for extrusion

This vertical integration ensures stable supply and consistent quality.

🏗 Extrusion (Shaping Process)

Step 2: Forming Solar Mount Profiles

The aluminum rods are fed into precision extrusion machines, forming the key structural components of solar mounting systems.

Beams, rails, and supports are created in standard or custom profiles
High dimensional accuracy ensures compatibility and ease of installation

🧪 Surface Treatment Process

Step 3: Corrosion Resistance Coating

To extend service life outdoors, all extruded profiles undergo advanced surface treatment. The material is submerged in a sequence of chemical baths, forming a protective anodized layer.

📦 Packaging and Final Assembly

Step 4: Secure Packaging for Shipping

Each aluminum component is sorted, protected with packaging film, and labeled for on-site installation. Pre-assembled kits or pre-punched holes are offered to simplify construction.

Efficient logistics
Reduced labor costs at the project site
Protection against transit damage

⚠️ Final Thoughts

Not all factories meet professional standards. Since aluminum prices and labor costs are relatively stable, significantly lower prices often mean that compromises were made on materials or processing.

Unlike accessories, defects in mounting systems affect the entire photovoltaic structure. Choosing Firstsolar means:

Verified manufacturing processes
Certified structural performance
Long-term project value

Request real manufacturing photos or inspection reports before purchasing, and never decide by price alone.
