JUSTSOLAR — Solar Module Manufacturer
For utility-scale · project-financed · institutional buyers

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 OEM, our certifications are equivalent, and our warranty is backed by insurance and reserves. 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

Tier-1 wrap arrangement

We supply cells, wafers, or finished modules to a BNEF Tier-1 brand under our existing OEM relationship. Modules ship under their name, their warranty, their bankability rating. You get the Tier-1 label financial institutions require, at ~$0.01–0.025/W premium over direct JUSTSOLAR supply.

Best for: Utility PPAs with institutional financing · Pension/infrastructure funds · BNEF-linked corporate mandates
Tradeoff: Premium above direct supply. Lead time +2-4 weeks for wrap paperwork.
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 is cheaper 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. Warranty + certifications equivalent to Tier-1. 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 is equivalent

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. The same equipment, the same QC, the same supply chain, the same team. For your LTA review: this is third-party validation that our capability meets the most demanding quality gates in the industry. For lenders that accept non-Tier-1 with technical mitigants, this is exactly that technical mitigant.

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.

Letter of Credit (L/C)

Large utility orders · 5+ containers · Institutional buyer

L/C at sight or deferred. Bank-to-bank payment guarantee. Accepted from most major international banks. Effectively acts as payment + performance backstop.

30% deposit + 70% against B/L copy

Established buyers · Mid-size projects · Repeat customers

30% T/T to secure production slot. Balance paid when we email the Bill of Lading copy — so buyer holds cargo control before full payment.

Trade Assurance (Alibaba-style escrow)

First-time buyers · Smaller orders · Risk-averse procurement

Escrow through Alibaba platform. Payment released only after shipment + buyer confirmation. Protects new buyers establishing trust.

Equipment finance / supplier credit

Large utility orders · Strategic long-term partnerships

30% deposit + 70% financed 3-12 months via buyer's trade bank. Available for confirmed BNEF Tier-1 wrap orders or established buyers with reference track record.

25+30 Year Warranty + Reserve Fund

25-year product warranty + 30-year linear performance warranty backed by an internal warranty reserve fund. Degradation: ≤0.40%/yr TOPCon · ≤0.35%/yr HJT. Year-25 output ≥87.4%, Year-30 output ≥84.8%. TUV-certified warranty curve.

Third-Party Warranty Insurance

Lenders requiring manufacturer-solvency-independent warranty coverage: we facilitate third-party warranty insurance (PowerGuard, Munich Re PVSE, Solar Insure) at ~$5-15/kW one-time premium. Claims paid by insurer regardless of manufacturer balance sheet — removes key bankability risk.

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 (strict NDAs). This is the independent third-party validation of our manufacturing capability. For projects requiring actual Tier-1 labeled modules for financing, we offer a Tier-1 wrap arrangement at modest premium. For most non-financed or privately-financed projects, direct JUSTSOLAR supply is cheaper + equivalent.
What's the premium for Tier-1 wrap arrangement?
$0.01–0.025/W depending on which Tier-1 brand is used, your order volume, and current market dynamics for that brand's wrap capacity. Indicative: for a 50 MW order at $0.015/W premium, that's $750K added cost to gain Tier-1 bankability. This is typically far less than the financing spread improvement or the equity reduction it enables, so the economics work for project-financed utility deals. Ask us to cost-model 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 (PowerGuard, Munich Re PVSE, Solar Insure) at ~$5-15/kW one-time premium — protects warranty claims independent of our balance sheet.
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.

Ready to structure your financing?

Send us your LTA questionnaire + project details and we'll return a structured response plus recommended commercial path within 5 business days. For 20+ MW projects, Director-level commercial and technical calls available during DD.
