Germany Solar Subsidies 2026: EEG, KfW and EPC Guide

What the EEG Framework Actually Covers in 2026

Germany's primary solar subsidy mechanism is the EEG Einspeisevergütung, a fixed feed-in tariff guaranteed for 20 years from the date of commissioning. The framework is governed by the Erneuerbare-Energien-Gesetz (EEG), most recently updated through EEG 2023 and Solarpaket I. The key parameters for EPCs advising clients in 2026:

Who receives it: All system owners who commission a solar installation and feed electricity into the German grid. Applies to residential, commercial, and industrial systems up to 100 kW. There is no distinction between "residential" and "commercial" at a 20 kW threshold: this framing does not exist in the current EEG structure.

The threshold that matters is 100 kW: Systems up to 100 kW receive the fixed FiT directly from their Netzbetreiber (grid operator). Systems above 100 kW must participate in Direktvermarktung, selling power directly to the market and receiving a Marktprämie (market premium) rather than the fixed FiT.

The FiT rate is locked at commissioning: Whatever rate applies in the month your system is commissioned is the rate you receive for 20 years, regardless of future changes to the degression schedule. Germany has not retroactively cut FiT rates for any existing installation in over 25 years of EEG history.

Partial vs full feed-in: what the distinction means

Most residential and commercial installations use partial feed-in (Teileinspeisung/Überschusseinspeisung): the system owner consumes solar electricity on-site and feeds only surplus into the grid. This is the standard configuration for systems with self-consumption.

Full feed-in (Volleinspeisung) means all generated electricity goes to the grid and none is consumed on-site. It receives a higher FiT rate but has become less attractive since the Solarspitzengesetz came into effect in February 2025 (see below). For most EPC proposals in 2026, partial feed-in with a storage component is the more economically efficient configuration.

Current EEG Feed-In Tariff Rates 2026

The following rates apply to systems commissioned between February 1, 2026 and July 31, 2026. Source: Bundesnetzagentur (primary), confirmed by BSW Bundesverband Solarwirtschaft rate table (February 2026).

For systems with mixed capacity (for example, a 30 kWp system), the first 10 kWp receives the higher rate and the remaining 20 kWp receives the lower rate. This tiered structure applies automatically based on installed capacity at commissioning.

August 1, 2026 rate change: The next degression takes effect August 1, 2026. Expected rates for systems commissioned August 1 to January 31, 2027: 7.71 ct/kWh (partial, up to 10 kWp) and 12.23 ct/kWh (full, up to 10 kWp), based on the 1% degression from current rates. The Bundesnetzagentur will publish confirmed figures at bundesnetzagentur.de before August 1. Systems commissioned before August 1 lock in the current rates for 20 years.

How degression works

Since February 1, 2024, FiT rates for new systems fall by 1% every six months, on February 1 and August 1 each year (§ 49 EEG 2023). This degression applies only to new installations. If your client commissioned a system in 2022 at a rate of, say, 8.2 ct/kWh, that rate continues unchanged for the remainder of their 20-year period. Later regulatory changes do not affect locked-in rates.

How to Access the EEG FiT: Correct Process for 2026

There is no separate "feed-in tariff application" process via a ministry portal. The process is straightforward:

1. Commission with a certified installer
   The installation must comply with VDE standards and local Netzbetreiber (grid operator) technical requirements. Inverters must meet grid-code compatibility requirements set by the Netzbetreiber, not a specific EEG minimum efficiency threshold.
2. Register in the Marktstammdatenregister (MaStR)
   MaStR registration at marktstammdatenregister.de is mandatory for ALL EEG-supported systems before FiT payments begin. Required for both FiT and Direktvermarktung systems. Must be completed within one month of commissioning. No MaStR registration means no EEG support.
3. Notify your Netzbetreiber
   The local grid operator arranges metering, confirms the applicable FiT rate for your commissioning month, and sets up payment. The Netzbetreiber pays the FiT directly to the system operator, not the BMWK or any federal ministry. No separate government application is needed.

There is no annual application deadline for the FiT. The rate you receive is determined entirely by your commissioning date. A system commissioned in July 2026 receives the February-to-July 2026 rate. A system commissioned in August 2026 receives the lower August rate. This is why commissioning date matters in client conversations.

KfW 270: Renewable Energy Standard Loan

The KfW-Programm Erneuerbare Energien "Standard" (Programme 270) provides low-interest loans for the construction, expansion, and acquisition of renewable energy installations, including solar PV on rooftops, facades, and open land. Source: KfW product information sheet (Merkblatt Kredit 270), May 2025 update, kfw.de primary.

• Loan amount: Up to 150 million euros per project for commercial and industrial applicants. Smaller thresholds apply for private individuals under related programmes.
• Eligible borrowers: Private individuals, companies of all sizes, municipalities, non-profits, and housing associations.
• What it covers: Panel procurement, inverter, mounting, installation, planning, and project costs.
• Combination with EEG FiT: Explicitly permitted. Drawing a KfW 270 loan does not disqualify a system from receiving the 20-year EEG FiT.
• How to apply: Applications go through a commercial bank acting as intermediary. KfW does not lend directly to end users.
• Interest rate: Determined by KfW based on the applicant's credit profile, project security, and market conditions. Check kfw.de/konditionen for current rates: do not cite a specific rate in client proposals as rates change with market conditions.

EPC action: For C&I clients in Germany where upfront capital is the primary objection, KfW 270 is a relevant financing conversation. The combination of a KfW 270 loan with a locked 20-year FiT at the current August 2026 pre-change rate creates a predictable cash-flow model that supports project approval.

Solarspitzengesetz: What Changed in February 2025

Since February 25, 2025, the Solarspitzengesetz (Solar Peak Law) applies to all new solar systems of 2 kWp and above. During periods when the wholesale electricity market price is negative (typically midday hours during high-generation sunny periods when supply exceeds demand), the EEG FiT payment is suspended. No compensation is paid for electricity fed into the grid in those quarter-hours.

The EEG includes a partial make-up mechanism at the end of the 20-year period for lost negative-price hours, but the practical implication for EPCs is clear: full feed-in configurations are now less financially attractive than before February 2025. The economic case for self-consumption combined with battery storage, or partial feed-in with high on-site consumption, is now stronger than at any point in the EEG's history.

When modelling annual FiT income for full feed-in system proposals in Germany, account for the expected number of negative-price hours in the relevant grid area. The Bundesnetzagentur and grid operators publish historical negative-price hour data that can inform this modelling.

Tax Benefits: Two Statutory Rights Every German Solar Client Has

Zero VAT on hardware and installation. Since January 1, 2023, solar systems installed on or in close connection with private residential buildings and public buildings in Germany are subject to 0% VAT (Umsatzsteuer) under §12 Abs. 3 UStG. It covers the supply of solar modules, inverters, battery storage systems, and installation. No application is required, the saving is automatic on the invoice. For a typical 10 kWp residential system costing €15,000 net, the pre-2023 19% VAT would have added roughly €2,850.

Income tax exemption for systems up to 30 kWp. Since the 2022 tax year, income from solar systems up to 30 kWp is fully exempt from income tax under §3 Nr. 72 EStG. EEG feed-in income, self-consumption income, and storage income all qualify. No trade registration is required for self-consumption, and the homeowner does not need to declare solar income in their tax return. For a household earning €500 to €1,000 per year in feed-in income who would otherwise sit in a 30% to 42% income tax bracket, the exemption is worth roughly €150 to €420 annually.

EEG 2027 Reform: Cabinet Approved, Parliamentary Process Now Underway

Germany's federal cabinet approved the government bill (Regierungsentwurf) for the EEG 2027 reform, alongside an accompanying grid connection package, on July 29, 2026. This is the formal next stage after the ministerial draft (Referentenentwurf), which went through an Arbeitsentwurf (January 22), a revised Referentenentwurf (April 21), and a further revision sent to state and industry consultation on July 17 with only three working days for comment.

The July 17 draft softened the original proposal for small systems: instead of losing subsidy entirely, systems under 25 kW commissioned from January 1, 2027 would receive a transitional payment (Übergangszahlung) starting at 5.2 ct/kWh, available for up to 36 months, declining every six months. Government sources have confirmed that further changes were made between that draft and the cabinet-approved version, specifically to the transitional payment mechanism and to redispatch reservation rules, but the published bill text needed to verify exact figures with confidence is not yet out. Do not quote the 5.2 ct/kWh figure to a client as final until the government bill text is published and cross-checked.

Systems of 25 kW and above keep access to a subsidized route through the market premium, with a new clawback provision (Refinanzierungsbeitrag, draft Section 20a) requiring operators of systems 100 kW and above to return revenue earned above a reference value to the grid operator.

New in the cabinet-approved text: redispatch reservation rules, the protection that shields a project's grid capacity while under construction, also changed. Reporting on the approved text describes a reduction in the base reservation period from 10 years to 6 years, but network operators can extend that reservation by up to 18 months under specified conditions. Renewable industry groups have criticized this as undercutting the headline reduction. This affects project financing timelines more than residential proposals, relevant for any C&I scale German pipeline.

The Bundestag now debates the bill starting this autumn, with passage expected by year-end and the new framework taking effect in 2027. One structural reason this timeline is firm rather than just political preference: the current EEG's own EU state aid approval expires at the end of 2026, meaning Germany needs a European Commission-approved replacement in place for 2027 regardless of domestic political timing. Existing systems keep full Bestandsschutz (grandfathering) regardless of the final outcome.

State and Municipal Programs: How to Find Them Without Quoting the Wrong Figures

Several German states and hundreds of municipalities offer battery storage grants, roof renovation bonuses, and additional solar subsidies stacked on top of the federal instruments above. These vary by state, change annually, and have budget caps that can be exhausted mid-year, it is not possible to quote a specific amount with confidence it'll still be correct by the time a client applies.

Check the relevant state energy agency before finalising any proposal that includes a state grant: the Bayerisches Staatsministerium für Wirtschaft for Bavaria, MWIDE NRW for North Rhine-Westphalia, the Berlin Senatsverwaltung für Wirtschaft for Berlin, and the respective Landesenergiebehörde elsewhere. The federal funding database at foerderdatenbank.de aggregates all federal, state, and municipal programs by postcode with current application links.

Action Checklist for EPCs in Germany

• Commission before August 1, 2026 to lock in current rates (7.78 ct/kWh partial, 12.34 ct/kWh full for systems up to 10 kWp) for 20 years, before the next degression takes effect
• Register all systems in the Marktstammdatenregister (MaStR) within one month of commissioning, which is a mandatory prerequisite for any EEG support
• Design for partial feed-in with storage in most client contexts, as full feed-in is less attractive post-Solarspitzengesetz (February 25, 2025)
• Discuss KfW 270 with clients where upfront capital is the primary objection: a KfW 270 loan is combinable with the EEG FiT
• Confirm inverter compliance with local Netzbetreiber technical requirements early in the design phase, as grid operator requirements vary by region
• Present the 0% VAT position clearly in residential proposals: no VAT applies to components and installation on residential buildings, making gross and net cost identical
• Frame the EEG 2027 draft accurately: present it as an urgency argument for 2026 commissioning, not as a confirmed phase-out
• Check bundesnetzagentur.de for confirmed August 2026 rates before they take effect on August 1

Frequently Asked Questions

Q1. What is the current EEG feed-in tariff rate for solar in Germany?

For systems commissioned between February 1 and July 31, 2026: 7.78 ct/kWh for partial feed-in and 12.34 ct/kWh for full feed-in on systems up to 10 kWp; 6.73 ct/kWh partial and 10.35 ct/kWh full for systems between 10 and 40 kWp. These rates are confirmed from Bundesnetzagentur primary publications and BSW Bundesverband Solarwirtschaft rate tables for February 2026. The next rate change takes effect August 1, 2026, with partial feed-in rates expected to fall to approximately 7.71 ct/kWh for systems up to 10 kWp. The Bundesnetzagentur will publish confirmed August rates at bundesnetzagentur.de before August 1.

Q2. Is the EEG feed-in tariff being phased out in 2026?

No. The EEG FiT is active and continues for all systems up to 100 kW commissioned in 2026 with a 20-year guarantee from commissioning date. Germany's cabinet approved the government bill for the 2027 reform on July 29, 2026, moving it from ministerial draft to formal legislation entering the parliamentary process. The July 17 draft proposed systems under 25 kW move to a declining transitional payment starting at 5.2 ct/kWh for up to 36 months rather than losing subsidy entirely, but government sources have confirmed some figures changed at the cabinet stage, and the published bill text isn't out yet to verify them precisely. Systems commissioned in 2026 under the current EEG will receive their locked rate for 20 years regardless of any future law changes. Germany has not retroactively cut FiT rates for any existing installation in over 25 years of EEG history.

Q3. Does commissioning date matter for the EEG FiT rate?

Yes, significantly. The FiT rate that applies in your commissioning month is the rate you receive for the full 20-year period. There is no separate application deadline. A system commissioned in July 2026 receives the current February-to-July 2026 rate (7.78 ct/kWh partial for up to 10 kWp) for 20 years. A system commissioned in August 2026 receives the lower August rate (expected approximately 7.71 ct/kWh), also for 20 years. The difference compounds over 20 years. For EPCs, this is a factually accurate urgency argument with clients who are considering delaying installation past July 31, 2026.

Q4. What capacity threshold determines whether a system gets the FiT or Direktvermarktung?

The threshold is 100 kW. Systems up to 100 kW (100 kWp installed capacity) receive the fixed EEG FiT directly from their grid operator for 20 years. Systems above 100 kW are required to participate in Direktvermarktung, selling power directly to the electricity market through a Direktvermarkter and receive a Marktprämie. There is no specific threshold at 20 kW in the current EEG FiT structure.

Q5. Can a KfW 270 loan be combined with the EEG feed-in tariff?

Yes. The KfW 270 programme (Erneuerbare Energien Standard) explicitly permits combination with EEG FiT for solar systems that feed electricity into the grid. Drawing a KfW 270 loan does not disqualify the system from receiving the EEG FiT. Applications for KfW 270 go through a commercial bank acting as intermediary; KfW does not lend directly to end users. Check kfw.de/konditionen for current interest rates as they change with market conditions. Source: KfW product information sheet (Merkblatt Kredit 270), May 2025 update.

Q6. What is the Solarspitzengesetz and how does it affect German solar projects?

The Solarspitzengesetz (Solar Peak Law) came into effect February 25, 2025. It applies to all new solar systems of 2 kWp and above. During periods when the wholesale electricity market price is negative (typically midday hours during high-generation periods); no EEG FiT payment is made for electricity fed into the grid. The EEG includes a partial compensation mechanism at the end of the 20-year period for lost negative-price hours. The practical implication for EPCs is that full feed-in configurations, where all generated electricity goes to the grid, are now less financially attractive than partial feed-in with on-site self-consumption or battery storage. When modelling annual FiT income for German client proposals, especially full feed-in systems, account for expected negative-price hours in the relevant grid area using historical data from Bundesnetzagentur or the relevant grid operator.

Q7. Does VAT apply to solar installations in Germany?

Since January 1, 2023, solar systems installed on or in close connection with private residential buildings and public buildings in Germany are subject to 0% VAT (Umsatzsteuer). This covers the supply of solar modules, inverters, and battery storage systems and their installation. For residential solar proposals, gross and net system cost are therefore identical. Confirm the specific VAT conditions with a qualified German tax advisor for commercial installations, as conditions may vary by project structure and building type.

Q8. Are there regional state-level subsidies in Germany stacked on top of the federal EEG FiT?

The EEG applies uniformly across all German federal states. Some Bundesländer and municipalities offer additional regional incentives that stack on top of the federal EEG support. These vary significantly by state and change periodically. EPCs should check with local authority programmes and state energy agencies for each project location rather than relying on general descriptions of what may be available. The federal EEG FiT and KfW 270 are available nationwide without variation by state.
