What this covers
Tier status doesn't guarantee compliance status
A Tier 1 bankability rating and FEOC-clean or domestic-content-qualified sourcing status are separate questions, and this guide covers why both need checking independently rather than assuming one implies the other.

FAQs
What actually determines a manufacturer's bankability tier?
Bankability tiers rank manufacturers mainly on financial and commercial strength that predicts whether they will honor long-term warranties, factors like balance-sheet stability, production scale, shipment history, and how widely financiers have accepted their products in projects. It is a lender-confidence signal, not a direct measure of module performance or quality in a given batch. Use it as a screening input for financing due diligence, not a full technical verdict.
Does Tier 1 status guarantee a module clears FEOC and domestic content requirements?
No. Tier status reflects bankability and financial strength, which is a different question from where a module's cells and materials are made. A Tier 1 manufacturer can still fall short of domestic content thresholds or trip FEOC restrictions depending on its supply chain. Verify compliance with sourcing documentation separately rather than inferring it from tier.
How often does tier data get reviewed and updated?
Most bankability tier lists are refreshed on a recurring cycle, commonly quarterly, as the analysts behind them reassess financials and shipment data. A manufacturer's standing can move between updates as its financial position or market acceptance changes. Treat any tier snapshot as current to its publication date and re-check before relying on it for a new project.
