American-Made Solar Panels: What the Label Means and Which Brands Make Them Here

American-made solar panels are available, but "American-made" can mean very different things: most US factories assemble panels from imported cells, while only a few make cells, wafers and ingots here too. Qcells, for example, says its Cartersville, Georgia plant began making ingots, wafers, cells and modules under one roof in June 2026. For homeowners, where a panel is made matters less than its datasheet specs, warranty terms and the strength of the company standing behind it.

Key takeaways

• A solar panel's supply chain has five main stages: polysilicon, ingots, wafers, cells and modules. Many "US-made" panels are only assembled here.
• Under FTC rules, an unqualified "Made in USA" claim means "all or virtually all" made in the US. "Assembled in USA" is a narrower claim.
• SEIA reported 52.3 GW of US module manufacturing capacity as of March 2025 (its latest dashboard update, April 2025), and said cell manufacturing returned to the US in 2024.
• The federal 25D homeowner tax credit is not allowed for expenditures made after December 31, 2025 (installation completed after that date), so there's no homeowner tax bonus for buying American-made panels.

What "American made solar panels" really means

A finished solar panel goes through several manufacturing steps:

1. Polysilicon: refined silicon raw material.
2. Ingots: large silicon crystals grown from the polysilicon.
3. Wafers: thin slices cut from the ingots.
4. Cells: wafers processed into working solar cells.
5. Modules: cells wired together, laminated under glass and framed into the panel you see on a roof.

A panel can be "made in America" at the module step while its cells come from overseas. That's common. The Solar Energy Industries Association (SEIA) supply chain dashboard, updated April 2025, says US module capacity reached 52.3 GW by March 2025, while cell manufacturing was only onshored in 2024 for the first time since 2019.

How to read the label

The Federal Trade Commission's "Made in USA" standard sets the rules for these claims:

• "Made in USA" (unqualified): The product must be "all or virtually all" made in the US, with negligible foreign content.
• Qualified claims: Wording such as "Made in USA of U.S. and imported parts" signals meaningful foreign content.
• "Assembled in USA": The product's principal assembly must take place in the US, and its last "substantial transformation" should also happen here. The parts may be imported.

The FTC generally doesn't treat a US brand name, or a company's US address listed in small print, as a Made in USA claim. Neither one tells you where a panel was actually made.

Which American-made solar panels can homeowners buy?

Here's what we could verify from company announcements, datasheets and trade press for three brands often quoted to US homeowners. This isn't a ranking, and it isn't a complete list.

Brand	US manufacturing (as reported)	What the datasheet or company says
Qcells	Dalton, Georgia module plant expanded to 5.1 GW in late 2023. Cartersville, Georgia plant targets 3.3 GW of ingots, wafers and cells and 3.5 GW of modules a year by Q3 2026.	Qcells calls Cartersville "America's first and only vertically integrated solar factory" (June 11, 2026 release). The Q.TRON BLK M-G2+ datasheet says the product "contains U.S. manufactured components" but doesn't name a country of manufacture.
Canadian Solar	5 GW panel assembly plant in Mesquite, Texas, with an expansion to 10 GW targeted for the second half of 2026; heterojunction cell plant in Jeffersonville, Indiana at 2.1 GW in 2026, planned to grow to 6.3 GW (Solar Power World, May 2026).	The TOPHiKu6 All-Black datasheet (v1.1, Nov. 2024) says "Assembled in the US from imported components."
REC	No US factory claimed on its Alpha Pure-RX page.	The US datasheet (rev. 6.2026) lists the origin as "Made in Singapore." Its header also says the modules are "assembled with foreign and domestic components."

Putting the numbers in context

Qcells says its Cartersville module line was already running at full capacity, about 16,700 panels a day, when cell production started. With Dalton, it puts its Georgia module capacity at 8.6 GW a year, or about 47,000 panels a day, and expects nearly 4,000 jobs across its Georgia operations.

Even brands with US plants may also import. Solar Power World reported that Canadian Solar expected to supply 6.5 to 7 GW of panels to the US market in 2026 from both domestic and global sites. So a brand name alone doesn't tell you where your panels came from.

Specific part numbers matter. A brand may sell the same panel family from several factories. Ask your installer for the exact model number and where that batch was made.

Do American-made panels perform better?

Not automatically. Output, heat tolerance and degradation depend on the panel design and materials, which you can compare on the datasheet:

• Efficiency: The Qcells Q.TRON BLK M-G2+ lists up to 22.5%. The REC Alpha Pure-RX lists 22.6%.
• Temperature coefficient: −0.30% per °C for the Q.TRON BLK, −0.24% per °C for the Alpha Pure-RX.
• Degradation warranty: Qcells guarantees at least 90.58% after 25 years; REC guarantees 92%.

Independent testing shows that build quality varies across the industry. Solar Power World reported in May 2026 that in Kiwa PVEL's 2026 PV Module Reliability Scorecard, a record 87% of manufacturers (and 61% of tested bills of materials) had at least one test failure. The scorecard also linked cost-cutting choices like thinner encapsulants and thinner frames to higher risk. Where a panel is assembled tells you less than how it has tested.

Warranties: why the company behind the panel matters

A 25-year warranty is only useful if the manufacturer is around to honor it. A company with US operations may be easier to reach for claims, though that isn't guaranteed. When you compare American-made solar panels, look at:

• Product warranty length: Qcells lists 25 years for the Q.TRON BLK M-G2+. REC lists 20 years for the Alpha Pure-RX, or 25 years with REC ProTrust. Canadian Solar's all-black datasheet lists 25 years only for certain rooftop installations in certain regions.
• Labor coverage: Most panel warranties cover the part, not the labor to swap it. REC ProTrust adds labor coverage when an REC Certified Solar Professional installs and registers the panels.
• Who handles claims: If your installer goes out of business, you'll deal with the manufacturer directly. See whether your solar warranty is void if the installer went bankrupt.

Tax credits and domestic content

For homeowners who buy a system, there's no federal tax reward for choosing American-made panels. The residential clean energy credit (Section 25D) is not allowed for expenditures made after December 31, 2025, and a solar expenditure counts as made when the installation is complete (IRS).

You may still hear about a "domestic content bonus." Qcells says its Cartersville modules will help developers qualify for the 10% Domestic Content Bonus under the Investment Tax Credit, which is a business credit, not the homeowner credit. If you're offered a lease or power purchase agreement, the leasing company's tax benefits are its own. Ask how they affect your price, but don't assume they do. Our solar lease vs buy guide explains the trade-offs.

How to verify a "Made in USA" solar panel claim

1. Get the exact model number and datasheet from your quote.
2. Check the datasheet's country-of-manufacture line. Look for words like "assembled" or "imported components."
3. Ask where the cells were made, not just the module.
4. Look up the panel on the California Energy Commission's Solar Equipment Lists. Keep in mind the CEC says manufacturers' self-reported information on those lists is not confirmed.
5. Read the warranty document for registration and installer requirements.

Next steps

Start with the solar panel calculator to estimate how many panels you need. Then compare brands and installers on our solar companies pages, including our Qcells profile. When you have quotes with specific panels, run them through the solar quote checker to see whether the price per watt makes sense.
