Explore databasesIf you’re evaluating domestic supply for residential or utility‑scale projects, understanding who makes up the top 10 solar panel manufacturers in USA will help you weigh local content advantages, factory‑backed warranties, and tariff‑exposed supply chains. This guide ranks the leading producers by confirmed module assembly capacity, all with operational or late‑stage commissioning lines on American soil.
US Solar Manufacturing: A Resurgence in Domestic Production
The landscape flipped faster than most grid forecasts predicted. After years of concentrated overseas supply, photovoltaic module assembly began racing back to the United States, pulled by federal manufacturing credits and a market hungry for panels that satisfy domestic content requirements. By early 2026, the nation’s annual nameplate module capacity had more than tripled its 2022 level, hitting a scale where domestic runs are measured in double‑digit gigawatts.
What Accelerated the Factory Buildout
The Inflation Reduction Act’s Section 45X production tax credit created a per‑watt incentive that essentially zeroed out the cost penalty of US assembly. Coupled with solar import tariffs and aggressive state‑level incentive packages, the economics flipped: it became cheaper to bolt a module together in Georgia or Ohio than to ship a finished panel across the Pacific. The result is a fleet of gigawatt‑class factories running crystalline PERC, bifacial, and thin‑film lines.
Where the Production Sprung Up
Production hubs crystallized in four regions that offer cheap power, deepwater ports, and rail connectivity. Georgia now hosts the largest single‑site module campus in the Western Hemisphere. Ohio runs multiple large‑scale thin‑film plants. Texas and Alabama added new greenfield builds and retrofitted brownfield sites, turning sun‑drenched states into renewable hardware suppliers.
How We Ranked the Top Manufacturers
We checked public company filings, state‑level economic development announcements, and industry data to pull each facility’s nameplate module capacity, expressed in gigawatts. Only US‑based assembly plants counted. Factories still in late‑stage commissioning with confirmed Q1 2026 production ramp‑ups made the cut; early‑stage proposals without finalized financing or ground‑breaking did not.
Module Assembly vs. Upstream Cells
Our ranking measures module assembly capacity, not cell or wafer fabrication. That distinction matters. Module assembly is the fastest supply‑chain step to scale domestically, but it frequently runs on imported cells. Think of it this way: a finished panel is a sandwich of glass, encapsulant, and a solar cell. Most of the “assembly” in the US today means buying that cell from Asia and laminating it into a frame. We unpack this dynamic further in the FAQ.
Selection criteria we applied:
- Operational or Q1‑2026 commissioning assembly lines only
- Publicly disclosed nameplate module capacity in gigawatts
- Exclusively US‑located facilities
- Module assembly step counted; upstream cell or wafer output excluded
Who Are the Top 10 Solar Panel Manufacturers in the USA? (2026)

| 10 | Boviet Solar | North Carolina (Greenville) | ~2.0 (planned) | Mono PERC, bifacial |
1. First Solar
First Solar runs the largest US module footprint, with thin‑film cadmium‑telluride lines coming out of Ohio. Its vertically integrated model—from semiconductor deposition to finished panel—avoids the cell‑import bottleneck, making it a favorite for utility‑scale projects chasing domestic content bonuses.
2. Qcells (Hanwha)
The Dalton, Georgia complex anchors Qcells’ US strategy. At over 5 GW of nameplate capacity, the campus produces mono PERC and bifacial modules for residential rooftops and large solar farms alike. It also houses one of the largest single‑crystal wafer operations in the West.
3. JinkoSolar
JinkoSolar’s Jacksonville, Florida plant assembles N‑type TOPCon panels, offering higher efficiency than traditional PERC. The facility operates around 1 GW and feeds both commercial installers and utility‑scale channels.
4. Canadian Solar
Canadian Solar’s Mesquite, Texas site is ramping toward 2 GW of mono PERC and bifacial output. Its deep project‑development pipeline often absorbs a share of factory production, creating a built‑in demand floor.
5. Meyer Burger
The Arizona plant uses heterojunction technology to produce high‑efficiency modules from its own cells. The Goodyear site marks Meyer Burger’s pivot to US manufacturing, targeting premium residential and commercial markets.
6. Silfab Solar
Silfab splits production between its long‑standing Washington facility and a new South Carolina plant. The combined footprint supplies mono PERC panels for residential installers, with an emphasis on durable American‑made frames.
7. Heliene
Heliene’s Mountain Iron, Minnesota factory has been a reliable mid‑tier module source for community solar and small utility projects. Its 500 MW line relies on imported cells but meets domestic content thresholds through US‑based lamination and framing.
8. Maxeon Solar Technologies
Maxeon’s New Mexico plant, still under construction, is slated to produce up to 3 GW of interdigitated back‑contact and shingled modules. Once operational, it would be one of the largest single‑site premium module facilities in the country.
9. Mission Solar Energy
Mission Solar, based in San Antonio, Texas, manufactures mono PERC panels that qualify for residential domestic content incentives. The relatively compact factory serves a loyal network of regional installers.
10. Boviet Solar
Boviet Solar’s planned 2 GW campus in North Carolina will add bifacial mono PERC capacity to the Southeast. The company is moving quickly through commissioning, with first panels expected by mid‑2026.

Frequently Asked Questions
US module assembly nameplate capacity now exceeds 30 gigawatts annually, more than triple the figure in 2022. The bulk of that output comes from plants in Georgia, Ohio, Texas, and Alabama, with thin‑film, PERC, and bifacial technologies all represented. This surge reflects the post‑IRA factory buildout, though most lines still rely on imported cells.
First Solar and Qcells lead with over 5 GW each, followed by a mix of international players like JinkoSolar, Canadian Solar, and Meyer Burger, plus domestic specialists such as Silfab, Heliene, and Mission Solar. The ranking reflects module assembly throughput, not upstream cell or wafer production.
The US has sharply narrowed the module‑assembly gap, but China retains overwhelming dominance in polysilicon refining and wafer manufacturing. American factories still import roughly 80–90% of their solar cells, meaning that while finished panel “made in USA” volumes are climbing fast, the supply chain remains deeply interdependent.
Major operational sites include First Solar’s Ohio complex, Qcells’ Dalton campus, and gigawatt‑scale facilities in Jacksonville, Florida, Mesquite, Texas, and Goodyear, Arizona. New brownfield expansions in Alabama and a massive upcoming plant in New Mexico will further reshape the map.
Brands like Qcells, Silfab, Mission Solar, and Heliene manufacture residential modules on American soil that qualify for domestic content incentives under the Inflation Reduction Act. Their specification sheets list US factory locations, making it straightforward for installers and homeowners to verify origin and secure adders.
