Bankability, honestly.
Three paths to your PPA close.

JUSTSOLAR is not on the BNEF Tier-1 list — and we're upfront about it. But our manufacturing lines already supply BNEF Tier-1 brands under NDA-protected OEM, and our DD pack includes the certifications, QC records, warranty documents and insurance support your team needs to review. For your project, there are three realistic paths to lender approval. This page walks through them honestly, with cost tradeoffs and documentation lists.

Three paths, pick what fits

The right structure depends on who's financing your project and what they require.

Scenario 1

Your PPA lender requires BNEF Tier-1

Bankability route under NDA

If the lender requires a public Tier-1 label, we review the covenant, project documents and volume before proposing a compliant structure. We do not publish partner names or public pricing for this route.

Best for: Utility PPAs with institutional financing · Pension/infrastructure funds · BNEF-linked corporate mandates
Tradeoff: More paperwork than direct supply. Lead time depends on document review and partner capacity.
Scenario 2

Your lender accepts non-Tier-1 with credit mitigation

Direct JUSTSOLAR + warranty insurance

Some lenders accept non-Tier-1 modules if project-level mitigants are in place: third-party warranty insurance (PowerGuard, Munich Re, kWh Analytics), sponsor guarantees, or performance reserves. For these, direct JUSTSOLAR supply can reduce the brand premium and the DD pack is straightforward.

Best for: Private infrastructure equity · Corporate C&I self-financing · Development banks with flexibility
Tradeoff: Requires loan officer / sponsor pre-approval of module. Plan for 2-4 week DD cycle.
Scenario 3

Your project self-finances or uses sponsor equity

Direct JUSTSOLAR — simplest + cheapest

No external lender, no bankability constraint. Direct JUSTSOLAR supply at factory-direct pricing with IEC / TUV documentation, warranty support and full QC records. Majority of our utility-scale 10-50 MW orders fall in this category.

Best for: Captive use by corporate · Municipality-owned · Private equity-funded IPPs
Tradeoff: Only your internal investment committee to satisfy. Simplest path.
Why our direct supply can cost less

Our lines already produce under Tier-1 labels.

Under NDA, our Jiaxing production lines manufacture finished modules for brands listed on the BNEF Tier-1 index. We do not disclose those brand names publicly. For your LTA review, this is a strong manufacturing validation signal: same production discipline, QC protocols, documentation trail and factory team behind our direct supply. If your lender accepts technical mitigants, this helps support the case without forcing you to pay the full retail Tier-1 brand premium.

Validation
Equipment and process audited by Tier-1 buyers with strict QC gates
Confirmation path
DD-level confirmation of Tier-1 OEM relationship available under mutual NDA
Limitations
We cannot disclose specific Tier-1 brand names. Your LTA can verify through industry network

Payment & Financing Structures

Four payment structures we support for utility-scale and institutional orders.

Standard new-buyer terms

Bankability FAQ

Is JUSTSOLAR BNEF Tier-1 listed?
No — we are not currently on the BNEF Tier-1 module manufacturer list. However, our production lines are used by brands that are on the BNEF Tier-1 list under OEM arrangements protected by strict NDAs. We do not disclose those brand names publicly. For projects requiring actual Tier-1 labeled modules for financing, Frank reviews the covenant and project documents before proposing a compliant bankability route. For most non-financed or privately financed projects, direct JUSTSOLAR supply avoids the retail brand premium and is usually more cost-effective.
What's the cost impact for a bankability route?
We quote it only case by case after NDA, covenant review, project document review and volume confirmation. The first question is whether direct JUSTSOLAR supply can pass your lender or technical advisor review. If not, Frank will compare the added structure cost against the financing benefit for your specific case.
What warranty reserve fund do you maintain?
We maintain an internal warranty reserve fund to cover module replacements through the 25-year product warranty period. Exact reserve size is disclosed under NDA for DD purposes. Supplementing our reserve: for buyers requiring guaranteed manufacturer solvency backing, we can facilitate third-party warranty insurance through recognized providers; pricing is confirmed case by case.
Do you have reference projects with owner contacts for DD calls?
Yes. Our reference project list includes utility, commercial, and distributed projects across 50+ countries. Standard DD reference list (8-10 projects with owner/EPC contact emails) available for 5+ MW prospective orders. For large utility DD (25+ MW), we can arrange direct owner conference calls. Projects range from 500 kWp C&I rooftops to 5+ MW utility ground-mount — ask for references matching your project type.
What cargo / transit insurance coverage do you provide?
All-Risk marine cargo insurance on every container, covering full container CIF value. Master policy with reputable underwriter, certificate-per-shipment provided with documentation. Damage rate is under 1.2% vs industry 3-5%. When damage occurs we handle the insurance claim paperwork for you. For on-site inverter/BOS equipment, separate installation-phase insurance can be structured through our insurance partners if required by your lender.
How do you handle lender technical advisor (LTA) reviews?
We've worked with major LTAs (WSP, Ramboll, DNV, Black & Veatch, Wood Mackenzie's PV Tech) on prior utility orders. For your LTA review, we provide: factory audit access (video + in-person), full technical specifications, equipment lists, QC protocols, warranty terms, supplier BOM, reference project performance data. LTA questionnaires typically returned within 2-3 weeks. For well-prepared DD cycles, we can target 10 business days.
What carbon footprint data do you provide for green-financed projects?
Product Carbon Footprint (PCF) per ISO 14067: 380-420 kgCO₂eq/kWp for China-origin modules, 240-280 kgCO₂eq/kWp for Macedonia EU-origin modules. Both are competitive vs industry averages. LCA reports available under NDA for green bond / sustainability-linked loan documentation. CBAM declaration-ready for EU imports. For deep decarbonization mandates, Macedonia origin + POE encapsulant configuration achieves our lowest footprint.
