In 50 words: The top US solar manufacturers in 2026 are led by First Solar (~11 GW nameplate CdTe) and Qcells (~8.4 GW integrated cell+module), with Silfab, Mission Solar, Heliene, and Meyer Burger as the next tier. This guide ranks the top US solar manufacturers by 2026 nameplate capacity, cell vs. module integration, IRA 45X positioning, and domestic-content bonus eligibility — the metrics that determine which US solar manufacturers win.
US solar manufacturing has been transformed by the IRA's 45X advanced manufacturing credit. Capacity that was uneconomic in 2020 is now profitable. This guide ranks the top US solar manufacturers in 2026 by operating module nameplate capacity, breaks down which have US cell production (critical for the IRA domestic-content bonus), and explains the trajectory through 2028.

2. First Solar (the #1 US solar manufacturer)
Why First Solar leads:
- Founded in 1999, the original US-domiciled solar manufacturer at scale
- CdTe thin-film technology (proprietary, no Chinese supply chain dependency)
- ~11 GW US nameplate capacity across AZ (HQ + manufacturing), OH (legacy), AL (under construction), IN (under construction)
- Series 7 module (520+ W) launched 2024, ramping through 2026–2028
- Vertically integrated — produces own CdTe coating + assembles modules in US
- Qualifies for IRA 45X manufacturing credit AND domestic-content bonus
2026 First Solar position: Single largest US solar manufacturer by capacity. Strong order book — 70%+ of 2026–2028 production already contracted. The "default safe choice" for US developers wanting domestic content.
3. Qcells / Hanwha
Why Qcells is #2:
- Hanwha (South Korean parent) made the largest single US solar manufacturing investment under the IRA — Dalton GA + Cartersville GA expansion
- Fully integrated US footprint: polysilicon (via REC Silicon), ingots, wafers, cells, modules all in Georgia
- 3.3 GW cell + 5.1 GW module capacity in US (2026 levels, ramping further)
- TOPCon technology
- Qualifies for full IRA 45X credit AND domestic-content bonus
2026 Qcells position: The most integrated US solar manufacturer. Strong fit for residential market via Qcells brand, and utility-scale via white-label and direct.
4. Silfab Solar
Why Silfab matters:
- Established US module manufacturer in Bellingham WA + Burlington WA + Fort Mill SC
- ~2 GW module capacity, expanding cell capacity in South Carolina
- N-type TOPCon technology
- Made in US branding strong for residential market
- Partial domestic-content eligibility (improving as SC cell ramps)
5. Mission Solar
Why Mission Solar:
- San Antonio TX manufacturer, ~1.5 GW US module capacity
- Crystalline silicon TOPCon
- Modules-only (cells imported); domestic-content eligibility limited
- Strong Texas and southwest US distribution
6. Heliene
Why Heliene:
- Mountain Iron MN, Riverside CA, and Indianapolis IN
- ~1.5 GW module capacity
- Modules-only currently, with US cell partnerships in development
- Strong "domestic-content-first" marketing position
7. Meyer Burger
Why Meyer Burger:
- Swiss-parent HJT technology specialist
- Goodyear AZ manufacturing facility, ~1.4 GW capacity (ramping)
- US cell + module both in Arizona
- Premium HJT technology positioning
- Eligible for IRA 45X + domestic-content bonus
2026 Meyer Burger position: Smaller scale than First Solar/Qcells but the only HJT specialist with US production. Premium niche.
8. Module-assembly-only US players (Jinko, LONGi)
JinkoSolar US (Jacksonville FL, ~2 GW capacity) and LONGi US (Pataskala OH, ~1 GW capacity) assemble modules in the US using imported Chinese cells.
Critical 2026 issue: Treasury's January 2026 final domestic-content rules require US-manufactured cells (not just US-assembled modules with imported cells) starting January 2028. This means:
- 2026: Jinko US and LONGi US can still partially qualify for domestic-content bonus
- 2027–2028: must add US cell capacity or lose qualification entirely
- Most analysts expect Jinko and LONGi US to add cell capacity, but timing is uncertain
Covered in detail in US solar domestic content rules.
9. The cell capacity bottleneck
The structural issue facing top US solar manufacturers: module capacity has scaled faster than cell capacity. As of 2026:
- US module capacity: ~25–30 GW
- US cell capacity: ~5–8 GW
- US wafer capacity: ~2 GW (very limited)
- US polysilicon capacity: ~3 GW equivalent (REC Silicon)
The gap means most US-assembled modules still use imported cells. This creates risk for the IRA domestic-content bonus economy: as Treasury's rules tighten, US module manufacturers without paired US cell capacity will lose competitiveness.
The 2026–2028 buildout race: First Solar (CdTe doesn't need silicon cells), Qcells (integrated), Meyer Burger (integrated HJT), Silfab (expanding cells in SC), and a wave of newer entrants — CubicPV, Suniva restart, others — are racing to fill the cell gap.
10. Frequently asked questions
Who is the top US solar manufacturer in 2026?
First Solar, with ~11 GW US module nameplate capacity. Qcells (~8.4 GW) is a close #2.
Are US solar manufacturers competitive with Chinese manufacturers on price?
Not directly. US delivered prices are 30-50% above Chinese FOB. The IRA incentives (45X + domestic-content bonus) close the gap for IRA-eligible projects.
Which US solar manufacturer has US cell capacity?
First Solar (CdTe integrated), Qcells (silicon integrated), Meyer Burger (HJT integrated), Silfab (partial cell). Most others assemble modules using imported cells.
Will Chinese solar manufacturers continue manufacturing in the US?
Likely yes (Jinko, LONGi, Trina), but they'll need to add US cell capacity by 2028 to maintain IRA domestic-content qualification.
What's the largest US solar manufacturing facility?
First Solar's Tempe AZ campus + Ohio + Alabama + Indiana combined exceeds 11 GW. Qcells' Dalton/Cartersville GA integrated campus is ~8.4 GW. Both are gigafactory-scale.
Does the IRA require US solar manufacturers to use US cells?
For the 10% domestic-content bonus credit: yes, by January 2028. The IRA 45X manufacturing credit itself is awarded based on US production but doesn't strictly require US cells for module qualification.
How fast is US solar manufacturing capacity growing?
US module capacity grew from ~9 GW (2022) to ~25-30 GW (2026). US cell capacity grew from ~1 GW to ~5-8 GW. Capacity will continue scaling through 2028.
