Serial-number verification workflow
- Get 10 random serial numbers from the container before it ships
- Submit each to the manufacturer's official warranty portal (LONGi, Jinko, Trina all have online lookups)
- Cross-check factory of origin — mismatched factory codes are the strongest fraud signal
- Verify EL images match the supplier-provided images for the same serial
- Upon arrival, physically inspect 2% of the container for backsheet consistency and frame stamping
Frequently asked questions
QAre Alibaba 'tier-1' listings trustworthy?
Only if the seller is the verified manufacturer's official store. Third-party trading companies claiming tier-1 stock are the #1 source of relabeling fraud.
