Buyer concern: “How do I know your quality is really equivalent to Tier-1?

Our lines already supply BNEF Tier-1 brands under NDA

Beyond supplying the JUSTSOLAR brand, our Jiaxing production lines also manufacture finished modules for brands on the BNEF Tier-1 index (strict NDA, we can't name them). Same equipment, same QC, same supply chain. For projects that require Tier-1 bankability for financing, we offer a Tier-1 wrap arrangement at +$0.01-0.025/W. For everyone else, direct JUSTSOLAR supply is cheaper with equivalent IEC + TUV certification and 25+30 year warranty.

Proof: See /oem-services for the full OEM story. DD-level confirmation of Tier-1 relationship available under mutual NDA for serious buyers.

Buyer concern: “Is this company a real manufacturer or just a trader?
