SPDG590-N144M10 · Sunpro Power · one SKU code, two products

Domestic vs Imported 590W Solar Panels.
Same module, two prices.

The Domestic Content version is assembled in Lyerly, GA and ships from Dublin, GA 31021. The imported version is the same 590W module assembled in Indonesia. The premium is 30.8% per watt. What it buys is IRA Section 45X eligibility and documented provenance — not performance.

SPDG590-N144M10 is not one product.

A SKU code identifies a design, not an origin. This one covers a module assembled in Georgia and a module assembled in Indonesia, and they are different products at different prices with different paperwork. Each side of the table below has its own datasheet — that is the material proof, not a claim of ours.

Where we stop

We publish the difference. We do not run your tax calculation.

The Domestic Content version costs 30.8% more per watt. Whether that premium is worth the 10% ITC bonus adder depends on your project's size, tax position and cost basis, and that calculation belongs to your tax counsel, not to a module supplier. What we owe you is the part we can actually evidence: the price of each version, where each module was assembled, where each cell came from, and the attestation, bill of materials and Bill of Lading that travel with every Domestic Content shipment.

Ask us for the documentation. Ask your accountant what it is worth.

Domestic Content FAQ

Frequently asked questions

What actually makes a module Domestic Content?

Where the MODULE is assembled, not where it is warehoused. Our Domestic Content 590W lots are assembled at our U.S. manufacturing partner facility in Lyerly, GA — Encapsulant / Junction Box / Ribbon assembled in USA — and ship from our Dublin, GA 31021 warehouse. Every Domestic Content shipment carries manufacturer attestation, a bill of materials and a Bill of Lading. The imported version of the same SKU code is assembled in Indonesia and carries none of that.

Is the imported 590W panel a different or lesser module?

No. Electrically and mechanically they are the same module: same 590W bin, same cell technology, same format. The premium on the Domestic Content version buys eligibility and documented provenance, not performance. If your project has no Domestic Content requirement, the imported version is the same panel for less money.

How much more does the Domestic Content 590W cost?

30.8% more per watt: $0.3898 against $0.2980 at the 11+ pallet tier. We publish the difference; we do not model what it is worth against the 10% ITC bonus adder, because that depends on your project's tax position and we are not tax advisors. Your tax counsel should run that number.

Can both versions go into the same project?

Physically yes — same module, same format, same electrical characteristics, so they combine on the same racking and in the same strings. Whether MIXING affects a Domestic Content claim is a question for your tax counsel: the cost-basis calculation depends on what fraction of the project qualifies. We supply the per-lot documentation that calculation needs; we do not perform it.

When does the imported 590W land?

The imported 590W allocation is 61.3 MW arriving Oct–Nov 2026. It is on the water, so it is quoted rather than sold from the shelf — the price is published and the CTA is Request quote. The Domestic Content version is not landed yet either: 43.01 MW arriving Nov 2026.
