Choosing the right solar mounting supplier is not only about price.
For EPC contractors, installers, and distributors, selecting an unqualified supplier can lead to structural failures, compliance risks, project delays, and even legal issues.

So how can you verify whether a solar mounting company is truly professional and reliable?

Here is a practical checklist used by experienced international buyers.

1. Check Real Certifications — Not Just a CE Logo

Many companies simply place a CE logo on their website. That does not prove compliance.

A reliable solar mounting company should provide:

• A valid CE certificate
• Clear reference to applicable standards (e.g., EN ISO standards)
• Certification body name and contact details
• Certificate number
• Issuance and expiry dates
• Online or QR-code verification

Important:
Always verify the certificate directly on the certification body’s official website. Some suppliers use expired or fake certificates.

2. Confirm Engineering Capability

A serious solar mounting manufacturer should have:

• Structural calculation capability
• Wind load and snow load design knowledge
• Compliance with Eurocode (EN 1991) or relevant local standards
• Project-specific customization ability

Ask these questions:

• Can they provide structural calculation reports?
• Can they design based on site wind speed and snow load?
• Do they understand local building codes?

If a supplier cannot answer technical questions clearly, they are likely only a trader.

3. Verify Factory Ownership and Production Capacity

Many “manufacturers” are actually trading companies.

You can verify a real factory by:

• Requesting factory photos and videos
• Asking for production process details
• Checking machinery (cutting, punching, anodizing, quality inspection)
• Confirming export records
• Requesting live video factory tours

A serious factory will not hesitate to show its production line.

4. Evaluate Material Transparency

Professional solar mounting companies clearly specify:

• Aluminum grade (e.g., AL6005-T5)
• Stainless steel grade (e.g., SUS304)
• Surface treatment (anodizing thickness)
• Bolt grade and corrosion resistance

If material specifications are vague, that is a red flag.

Low-grade materials may reduce cost, but they increase long-term corrosion risk — especially in coastal or high-humidity environments.

5. Check Project References

Ask for:

• Overseas project cases
• Installation photos
• Client references (if available)
• Export markets

A reliable supplier usually has experience in multiple regions (EU, Southeast Asia, Middle East, etc.).

Real project experience demonstrates structural reliability and product maturity.

6. Assess Technical Documentation Quality

Professional companies provide:

• Installation manuals
• CAD drawings
• Product datasheets
• Load calculation reports
• Warranty documentation

If documentation is poorly written or copied from other companies, this indicates low professionalism.

7. Review Communication and Technical Support

A serious supplier:

• Responds clearly to technical questions
• Provides engineering suggestions
• Understands EPC workflow
• Offers after-sales support

If communication is slow, unclear, or purely price-focused, long-term cooperation may be risky.

8. Beware of Unrealistically Low Prices

Solar mounting systems are structural safety components. Extremely low prices may indicate:

• Lower material grade
• Thinner aluminum profiles
• Reduced anodizing thickness
• No real structural verification

Always compare not just price — but material specification and engineering compliance.

9. Look for Long-Term Industry Focus

Companies specializing only in solar mounting systems tend to have:

• Deeper technical understanding
• Continuous product upgrades
• Better system compatibility
• Stable supply chains

Suppliers selling “everything” may lack real expertise.

Final Checklist Before You Choose a Solar Mounting Supplier

Before placing an order, make sure the company can provide:

✔ Verifiable CE certification
✔ Engineering calculation capability
✔ Transparent material specifications
✔ Real factory evidence
✔ Overseas project experience
✔ Professional documentation
✔ Technical support
