How to compare a solar module supplier with a BNEF Tier 1 manufacturer
BNEF Tier 1 is a quarterly manufacturer classification based on project and asset-finance data. It can be a contract input, but buyers still need to match the exact supplier, model, factory, evidence and order to their own requirements.

What JUSTSOLAR can state publicly
JUSTSOLAR has NDA-protected OEM manufacturing experience for established Tier 1 brands. Customer names are not published.
What that statement does not mean
It does not mean JUSTSOLAR is currently listed by BNEF, and it does not transfer another company's listing, brand, warranty, endorsement, product evidence or lender acceptance.
Choose the right comparison path
Start with the written procurement or finance requirement, not a general brand assumption.
Path 2
The finance clause requires current BNEF Tier 1 status
Verify the relevant quarter, legal manufacturer and lender interpretation before assuming any supplier or model is accepted.
Path 3
The contract does not require a Tier 1 classification
Compare the exact model, certificate holder, production site, quality evidence, warranty issuer and order terms. Do not compare labels alone.
Path 4
The order is OEM or private label
Separate the brand owner, legal seller, manufacturer, production site, certificate holder and warranty issuer in the written review.
Six evidence questions replace a blanket ranking

Does JUSTSOLAR claim to be on the current BNEF Tier 1 list?
No. This page makes no claim that JUSTSOLAR is on the current BNEF Tier 1 list. Check the current BNEF report and the exact contract requirement for each transaction.
Does Tier 1 OEM experience transfer a customer's status to JUSTSOLAR?
No. NDA-protected OEM manufacturing experience does not transfer another company's listing, brand, warranty, endorsement or lender acceptance to JUSTSOLAR.
Is a Tier 1 classification enough to approve a module?
No single label completes product review. Match the exact model, certificate holder, production site, reports, quality evidence, warranty issuer and order documents to the buyer's requirements.
Will JUSTSOLAR publish its OEM customer names?
No. Customer relationships are confidential. We do not publish names or imply endorsement. Frank or the Director determines what order-specific evidence can be reviewed without breaching confidentiality.
What if the tender names a specific Tier 1 brand?
Follow the tender. Do not assume an alternative is accepted unless the tender owner provides a written substitution or approved-equal route.
What should I send for a supplier comparison?
Send buyer type, country, product, quantity and destination port or site. Add the exact tender, lender or approved-equal clause and requested evidence list when available.
Ask for an order-specific comparison
Send the five RFQ details and the exact tender or lender clause. Frank or the Director reviews product, evidence, availability, price, payment, delivery, warranty and any formal offer or PI before commitment.
