EU CBAM impact on solar imports 2026: what's actually changing in 2026 and 2027

In 50 words: The EU Carbon Border Adjustment Mechanism (CBAM) targets cement, iron/steel, aluminum, hydrogen, electricity, and fertilizers as of 2026 — solar modules are NOT directly in scope. But CBAM indirectly affects EU solar imports via the steel and aluminum content of trackers and racking. This guide breaks down the actual 2026 CBAM impact on EU solar imports and what's coming in 2027 if scope expands.

CBAM gets discussed as a major risk for EU solar import economics, but the actual 2026 impact is much smaller than headlines suggest. Solar modules are not in CBAM scope. The indirect impact via steel/aluminum content of racking and trackers is meaningful but limited. This guide gives the working CBAM impact numbers for EU solar imports in 2026, and the scenarios for scope expansion in 2027–2028.

1. What CBAM actually covers in 2026

CBAM in its definitive period (from January 1, 2026) covers imports of:

Cement
Iron and steel (including downstream products)
Aluminum
Fertilizers
Hydrogen
Electricity (cross-border)

Importers must purchase CBAM certificates equivalent to the EU ETS carbon price for embedded emissions in covered products. 2026 EU ETS price: ~€85–€105/tonne CO2.

Notably absent from the 2026 CBAM scope: solar modules, batteries, EV components, electronics, wind turbine blades.

For broader EU policy context, see our coverage on EU solar manufacturing under NZIA 2026.

2. Why solar modules are NOT in CBAM scope (yet)

The European Commission deliberately excluded solar modules from initial CBAM scope for three reasons:

EU solar import dependence: ~85% of EU solar modules are imported. Adding CBAM cost to modules would slow the EU solar deployment trajectory — politically problematic given REPowerEU and Green Deal targets.
Compliance complexity: solar modules have a complex multi-stage supply chain (polysilicon → wafer → cell → module) crossing many jurisdictions. CBAM calculation for solar modules would be administratively heavy.
NZIA mechanism preferred: the EU Net-Zero Industry Act handles solar manufacturing support via procurement preferences, not import carbon costs. Adding CBAM on top would be politically awkward.

The European Commission has indicated solar modules MAY be added to CBAM in a 2027–2028 review, contingent on EU solar manufacturing scale-up.

3. Indirect CBAM impact: steel and aluminum in solar BoS

Even with solar modules excluded from CBAM, EU solar imports face indirect cost increases via:

| BoS component | Material content | CBAM exposure | |---|---|---| | Mounting structures (steel) | Pure steel | Direct CBAM if imported | | Trackers (steel + aluminum) | Mix steel + aluminum | Direct CBAM if imported | | Aluminum module frames | Aluminum | Direct CBAM if imported | | Cable trays + DC harness | Aluminum | Direct CBAM if imported | | Substations + transformers | Steel | Direct CBAM if imported | | Inverters | Limited steel/aluminum | Minor exposure |

The biggest impact is on steel and aluminum content in racking, trackers, and mounting — roughly €3,000–€7,000 per MW of additional cost for utility-scale solar projects using imported Chinese steel/aluminum structures. For residential solar, the impact is much smaller (~€20–€50 per kWp).

4. CBAM cost calculation for a typical EU solar project

For a 100 MWp utility-scale solar project in Germany 2026 using Chinese-imported steel trackers:

Steel embedded in tracker: ~80 tonnes/MW × 100 MW = 8,000 tonnes
Embedded CO2 emissions (Chinese coal-based steel): ~2.0 tCO2/tonne steel = 16,000 tCO2
EU ETS price 2026: ~€95/tCO2
CBAM certificate cost: 16,000 × €95 = €1.52M total
Per-MW impact: €15,200/MW

This is meaningful — roughly 1.5–2% of total installed solar farm cost. EU developers are increasingly sourcing EU or Turkish steel for racking to avoid the CBAM hit.

For residential systems, the indirect CBAM cost is much smaller — typically €30–€50 per kWp, or under 3% of installed solar panel price.

5. 2027–2028 CBAM expansion: what's being debated

The European Commission is consulting on potential CBAM scope expansion for the 2027 review. Solar-relevant categories being debated:

| Category | Likelihood of inclusion 2027–2028 | |---|---| | Solar modules | Low (political resistance) | | Inverters | Low (small embedded emissions) | | Cells (separately from modules) | Medium | | Polysilicon | Medium-high (high embedded emissions) | | Wafers | Medium | | Battery cells | High (active discussion) | | Wind turbine components | Medium |

If polysilicon enters CBAM in 2028, it would meaningfully change EU solar import economics — polysilicon is energy-intensive and Chinese production has high embedded emissions vs. EU/US (REC Silicon, Wacker).

6. CBAM vs EU solar imports from China, Vietnam, India

The country-of-origin impact of CBAM on EU solar imports:

| Origin | CBAM exposure on steel/aluminum BoS | Strategic response | |---|---|---| | China | Highest (coal-based steel) | EU developers diversifying sourcing | | Vietnam | Medium (less coal-intensive) | Limited shift | | India | Medium-high (mostly coal) | Limited shift | | Turkey | Low (modernized steel sector) | Increasing EU solar BoS sourcing from Turkey | | EU member states | Zero (no CBAM on intra-EU) | Premium for EU-made racking + trackers |

The structural impact: CBAM is gently steering EU solar BoS sourcing toward Turkey, EU, and (eventually) cleaner-grid origins. Chinese steel and aluminum lose some price advantage.

7. Strategic response by EU solar developers

EU solar developers are adapting to CBAM in 2026 through:

Pre-CBAM stockpiling: ordering 6–12 months of racking/tracker inventory before CBAM definitive period started
EU + Turkish sourcing: shifting to Salzgitter, ArcelorMittal Europe, Tosyali (Turkey) for steel racking
Tracker specification changes: lighter-gauge designs reduce steel content per MW
Domestic content premium acceptance: EU-made modules + EU-made racking command 8–15% premium, partially offset by CBAM avoidance

The net 2026 impact on EU solar import economics: modest cost increase (~1–2% for utility-scale, less for residential), gentle reshoring incentive, no dramatic disruption.

8. Frequently asked questions

Does CBAM apply to solar modules imported into the EU in 2026?

No. Solar modules are not in CBAM scope as of 2026. Only cement, iron/steel, aluminum, fertilizers, hydrogen, and electricity are in direct scope.

How does CBAM affect EU solar imports indirectly?

Via the steel and aluminum content of racking, trackers, and mounting structures. For utility-scale solar, this adds ~€15,000/MW to costs when using Chinese-imported steel.

Will solar modules be added to CBAM in 2027?

Unlikely. The European Commission has signaled reluctance to add solar modules to CBAM due to EU solar import dependence. Polysilicon and battery cells are more likely candidates for 2027–2028 expansion.

How much does CBAM increase EU solar project cost?

For utility-scale projects with Chinese-imported steel racking: ~1.5–2% of total installed cost. For residential solar: under 3% of total cost.

How can EU solar developers reduce CBAM exposure?

Source steel and aluminum BoS from EU producers (Salzgitter, ArcelorMittal Europe) or Turkey (Tosyali). EU-made modules + EU-made BoS minimize CBAM exposure.

What's the EU ETS carbon price in 2026?

~€85–€105 per tonne CO2 in early 2026. CBAM certificates are priced at this rate.

Does CBAM apply to renewable electricity imports?

Yes, electricity is in CBAM scope. Cross-border renewable electricity imports into the EU now require CBAM certificates calculated on the average grid emissions intensity of the exporting country.
