Tariffs on Solar Panels 2026: Rates by Country and Installer Impact
Solar panels are subject to one of the most complex tariff stacks in the US import schedule: Section 201 safeguards, Section 301 layer (for China), antidumping and countervailing duty orders, the reciprocal baseline, plus base MFN duty. For Chinese-origin modules, the cumulative rate exceeds 250%. For Vietnamese, Malaysian, and Cambodian modules, the tariff landscape changed dramatically in 2024-2025 with new AD/CVD orders. This guide breaks down the math by country and explains what it means for US installers, developers, and homeowners.
The tariff layers stacked on solar imports
| Layer | Legal basis | Rate (varies) |
|---|---|---|
| Base MFN duty | HTSUS 8541.43 column 1 | 0% |
| Section 201 safeguard | Trade Act of 1974 | 14.25% (declining, was 30% in 2018) |
| Section 301 | USTR China action | 50% (China only; doubled in 2024) |
| AD duty | Commerce Department orders | 0-250%+ by country/producer |
| CVD duty | Commerce Department orders | 0-50%+ by country |
| Reciprocal baseline | April 2025 EO | 10-50% by country |
Effective rates by country in 2026
| Country | Base + 201 | 301 | AD/CVD | Reciprocal | Cumulative |
|---|---|---|---|---|---|
| China | 14.25% | 50% | 165-254% | 0% (replaced by 301) | 230-320% |
| Vietnam | 14.25% | 0% | 53-271% (2024 order) | 20% | 87-305% |
| Malaysia | 14.25% | 0% | 34-203% (2024 order) | 24% | 72-242% |
| Cambodia | 14.25% | 0% | 117-271% (2024 order) | 10% | 141-295% |
| Thailand | 14.25% | 0% | 23-202% (2024 order) | 36% | 73-252% |
| South Korea | 14.25% | 0% | 0% | 15% | ~29% |
| India | 14.25% | 0% | 0% | 26% | ~40% |
| US-made (domestic) | 0% | 0% | 0% | 0% | 0% |
The 2024 AD/CVD investigation against Vietnam, Malaysia, Cambodia, and Thailand was the most significant shift — these countries had been the workaround for Chinese tariffs since 2018 and now face their own elevated rates.
Why solar tariffs are so complex
Three policy threads converge on solar:
- Industrial protection — US solar manufacturing (First Solar, Q Cells US, etc.) gets tariff cover
- National security/clean energy — domestic solar capacity treated as strategic
- Anti-circumvention — preventing Chinese producers from routing through Southeast Asia
The result: an importer of solar panels faces more potential tariff scrutiny than almost any other category.
Real cost example — 1 MW utility-scale project, 2,800 panels
| Source | FOB cost per panel | Landed per panel | Total project cost (panels) |
|---|---|---|---|
| Chinese-brand factory in China | $95 | ~$315 | $882,000 |
| Vietnamese factory (high AD rate) | $110 | ~$220 | $616,000 |
| South Korean factory | $135 | ~$174 | $487,000 |
| US-made (First Solar) | $145 | $145 | $406,000 |
US-made wins on landed cost despite higher FOB. This is the explicit policy goal.
The market response 2024-2026
- Massive Southeast Asia capacity buildout halted. Plants in Vietnam, Malaysia, Cambodia that opened in 2020-2023 to bypass Chinese tariffs now face their own AD/CVD orders.
- Korean and Indian factories growing. Lower tariff exposure makes them competitive.
- US domestic manufacturing surge. First Solar, Hanwha Qcells, Hyundai, Trina (US plant), Suniva expanding. New US capacity announced exceeds 60 GW.
- Mexican assembly being explored under USMCA, but rules of origin remain barrier.
- Stockpiling pre-AD/CVD. Importers who bought 2023-2024 Vietnamese panels in advance secured below-tariff inventory.
Impact on installers and developers
| Project type | 2024 cost | 2026 cost | Change |
|---|---|---|---|
| Residential (8 kW system) | $22,000 | $26,500 | +20% |
| Commercial (250 kW) | $425,000 | $510,000 | +20% |
| Utility (10 MW) | $8.5M | $10.5M | +23% |
Federal tax credits (Investment Tax Credit, Production Tax Credit) partially offset for projects placed in service through 2032, but pricing pressure has slowed project timelines.
How to navigate solar tariffs in 2026
- Run AD/CVD check before sourcing. Vietnamese, Malaysian, Cambodian, Thai panels all face individual orders by manufacturer. Some manufacturers have lower rates than others.
- Confirm the producer-specific rate. The "all-others" rate is usually punitive; cooperating producers have lower individual rates.
- Verify substantial transformation. CBP audits solar transshipment aggressively. Crystalline silicon cell production must occur in the country claimed.
- Consider Korean and Indian sources. No AD/CVD currently; reciprocal baseline only.
- Domestic content credit. US-made panels can earn additional ITC bonus credits, narrowing landed cost gap further.
- Lock in long-term supply contracts. Volatility means short-term spot buying is risky.
What's pending for 2026-2027
- Section 201 safeguard expires February 2026 — uncertain if renewed
- Section 301 review may add new product categories (inverters, racking already discussed)
- New AD/CVD petitions from US industry against Indian and Korean producers
- Bonus Investment Tax Credit (IRA) for domestic-content projects continues through 2032
- Foreign Trade Zone usage by US solar manufacturers to import cells tariff-deferred
Frequently asked questions
What is the total US tariff on Chinese solar panels in 2026?
Cumulatively around 230-320% when stacking Section 201 safeguard, Section 301, and AD/CVD orders. Chinese-origin solar panels are effectively shut out of the US market.
Are Vietnamese solar panels still cheaper than Chinese?
Yes, but the gap narrowed dramatically with the 2024 AD/CVD orders. Vietnamese panels now face 53-271% AD/CVD plus 14.25% Section 201 plus 20% reciprocal. Still cheaper than Chinese, but not by as much.
Is solar from South Korea or India hit by tariffs?
Only the 14.25% Section 201 and the reciprocal baseline (15% for Korea, 26% for India). No AD/CVD currently. This makes them increasingly competitive.
What about US-made solar panels?
No tariffs, plus eligible for Investment Tax Credit bonuses for domestic content. US capacity expanded dramatically 2023-2026 but still doesn't meet total demand.
Can I claim drawback on solar tariffs?
Yes for re-exports. See our duty drawback guide. Section 301, 232, and reciprocal layers are all recoverable.
Will tariffs be lifted under a different administration?
Section 301 and AD/CVD are not easily reversed. Section 201 is up for review in 2026. Reciprocal tariffs are in litigation. Don't bet on tariffs disappearing in the near term.
