Germany EEG solar feed-in tariff 2026: rates, rules, and the Solarpaket reforms

In 50 words: Germany's EEG solar feed-in tariff (Einspeisevergütung) in 2026 ranges from 5.81 to 12.92 ct/kWh depending on system size and feed-in modality. The tariff is guaranteed 20 years from commissioning. The Solarpaket I (effective 2024) and Solarpaket II (effective 2025) reforms simplified registration, allowed shared building solar (Mieterstrom), and reduced administrative barriers. This guide covers the 2026 EEG rates, eligibility, and the reform trajectory.

Germany's EEG feed-in tariff for solar has been the foundation of the country's residential solar market since 2000. The 2024-2025 Solarpaket reforms tightened rates but dramatically streamlined administration. This guide gives the 2026 EEG solar feed-in tariff rates, walks through how to qualify, and explains the Solarpaket changes that matter to homeowners and installers.

1. The 2026 EEG solar feed-in tariff rates

| System size | Volleinspeisung (full feed-in) | Überschusseinspeisung (surplus only) | |---|---|---| | Up to 10 kWp | 12.92 ct/kWh | 8.20 ct/kWh | | 10 to 40 kWp | 10.86 ct/kWh | 7.10 ct/kWh | | 40 to 100 kWp | 8.85 ct/kWh | 5.81 ct/kWh | | 100 to 750 kWp | Tender-based (EEG-Marktprämie) | — | | Above 750 kWp | Tender-based | — |

These rates apply to systems commissioned in 2026 H1. The Bundesnetzagentur reduces rates by 1% every six months (the "Degression"), so systems commissioned in 2026 H2 will get slightly lower rates.

2. Volleinspeisung vs Überschusseinspeisung: which to choose

Two modalities, fundamentally different economics:

Volleinspeisung (full feed-in, 12.92 ct/kWh for ≤10 kWp):

All production exported to grid
Higher per-kWh EEG tariff
No self-consumption against retail electricity (€0.32+/kWh)
Best for: households with very low electricity consumption, owners of vacation homes, or those who don't want to manage self-consumption optimization

Überschusseinspeisung (surplus only, 8.20 ct/kWh for ≤10 kWp):

Self-consumption first, then export surplus
Lower per-kWh EEG tariff
Self-consumed kWh worth retail price (€0.32+/kWh) — much higher than the export tariff
Best for: typical German households with moderate-to-high electricity consumption

For a typical German household consuming ~4,000 kWh/year with an 8 kWp solar system producing ~8,000 kWh/year, Überschusseinspeisung delivers ~€1,800/year of value vs ~€1,030/year for Volleinspeisung. The lower per-kWh EEG rate is more than compensated by self-consumption against retail electricity.

3. How the 20-year EEG tariff guarantee works

The German EEG solar feed-in tariff is guaranteed for 20 calendar years from the date of commissioning (Inbetriebnahme), plus the remainder of the year of commissioning.

A system commissioned in March 2026:

Tariff guarantee: through December 31, 2046
Total EEG income period: ~20.75 years
After 2046: post-EEG (see Section 7)

The EEG tariff cannot be reduced retroactively. Once your system is registered and grid-connected, your tariff is locked.

The 20-year EEG guarantee is the foundation of German residential solar economics. It removes the most important risk for residential investors and lets banks finance solar at attractive rates (3.5-5% APR through KfW programs).

4. Solarpaket I (2024) changes

Solarpaket I (effective May 2024) introduced:

Simplified registration for systems ≤30 kWp: one-step online registration via MaStR (Marktstammdatenregister), no separate DSO approval needed for small systems
Removed grid-connection fee for systems ≤30 kWp: previously some DSOs charged €500-€2,000; now free for residential
Streamlined Mieterstrom (tenant electricity): simpler shared building solar arrangements
Removed AC-side power limitation: previously 70% rule limited residential systems; eliminated
Special agri-PV bonus (1.2 ct/kWh extra for agrivoltaics): incentive for combined farming + solar
EEG tender thresholds raised: smaller systems can opt into tenders for higher tariffs

Solarpaket I is widely credited with accelerating 2024-2025 German solar deployment by ~20%.

5. Solarpaket II (2025) changes

Solarpaket II (effective from mid-2025) added:

Building Energy Sharing (Gebäudestromnutzung): simplified rules for sharing solar within multi-unit buildings without needing full Mieterstrom contracts
Negative pricing rules: if wholesale price is negative for >4 hours, solar feed-in tariff is paused for those hours (incentivizes battery + self-consumption)
Smart meter rollout acceleration: streamlined deployment of digital meters for solar households
Cell-side bonus for EU-manufactured modules: small bonus (0.5 ct/kWh) for systems using EU-manufactured solar cells, aligned with NZIA — see EU solar manufacturing under NZIA 2026
Battery integration support: simplified rules for adding batteries to existing systems within the 30 kWp threshold (0% VAT applies)

6. Registration: how to qualify for EEG

To qualify for the EEG solar feed-in tariff, a German residential solar installation must:

Be installed by a registered installer (Elektrofachbetrieb)
Use modules and inverters compliant with VDE-AR-N 4105 (technical grid connection standards)
Be registered in MaStR (Marktstammdatenregister) within 1 month of commissioning
Be commissioned and tested by a certified electrician
(For Überschusseinspeisung) have a smart meter installation

The full registration process now takes 2-4 weeks (down from 6-12 weeks pre-Solarpaket I).

7. Post-EEG (after 20 years): what happens next

Systems that complete their 20-year EEG period continue producing — but the tariff guarantee ends. Post-EEG options:

Continue self-consumption + spot price export: most common; export compensated at spot wholesale price (~5-10 ct/kWh)
Repowering: replace modules with new ones, re-register for new EEG term — see solar repowering Europe 2026
Sell electricity via direct contract or PPA: increasingly available for larger residential or commercial systems
Donate / sell system: some post-EEG systems are decommissioned or sold to off-grid uses

The first big wave of post-EEG systems is approaching in 2030-2032 (from the 2010-2012 deployment boom). Germany's "Post-EEG" framework is being actively developed in 2026.

8. Frequently asked questions

What is the EEG solar feed-in tariff in 2026?

8.20 ct/kWh for surplus feed-in on residential systems up to 10 kWp. 12.92 ct/kWh for full feed-in. Higher for larger systems via the EEG-Marktprämie tender process.

How long is the EEG feed-in tariff guaranteed?

20 calendar years from the year of commissioning, plus the remainder of that commissioning year. Typically 20-20.75 years total.

Volleinspeisung or Überschusseinspeisung — which is better?

Überschusseinspeisung for almost all German households with meaningful electricity consumption. Self-consumed kWh is worth retail price (~€0.32/kWh), much more than even the higher Volleinspeisung tariff.

What did Solarpaket I and II change?

Solarpaket I (2024) simplified registration, removed grid fees, streamlined Mieterstrom. Solarpaket II (2025) added building energy sharing, EU-manufacturing bonus, and battery integration support.

Can I add a battery to an existing EEG-registered system?

Yes. Solarpaket II simplified battery additions to existing systems, and the 0% VAT applies to battery additions within the 30 kWp threshold.

What happens when my 20-year EEG period ends?

Several options: continue self-consumption + spot-price export, repowering, sell electricity via PPA, or decommission. The "post-EEG" framework is evolving.

Is the EEG solar feed-in tariff being reduced over time?

Yes, by 1% every six months ("Degression"). Systems commissioned later get slightly lower rates. But the 20-year tariff guarantee, once locked in at commissioning, is fixed for the full term.
