Solar Incentives in Germany 2026: EEG Feed-in, KfW Loans & 0% VAT
Last updated July 2026
Germany's solar support is anchored in the Renewable Energy Sources Act (EEG), which guarantees grid access and statutory payment for electricity fed into the grid. Alongside it sit KfW low-interest loans, a 0% VAT rate on residential PV, and BAFA grants for solar heating. Every system must be registered in the Marktstammdatenregister (MaStR). Always confirm current rates at the official source.
Germany's solar support is anchored in the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG), which guarantees grid access and statutory remuneration for electricity fed into the public grid, either as a fixed feed-in tariff (Einspeisevergütung) or, for larger systems, as a market premium (Marktprämie) on top of direct sales. Alongside this operating support, the federal promotional bank KfW offers low-interest financing for renewable-energy investments, a nationwide zero VAT rate applies to the purchase and installation of qualifying residential photovoltaic systems, and BAFA administers building-related subsidies that mainly cover solar thermal and renewable heating. Every grid-connected system must be recorded in a central official register. Because rates, tax thresholds and programme terms are updated regularly, exact figures should always be confirmed at the official source.
Registering your solar system on the grid
Marktstammdatenregister (MaStR)
The Marktstammdatenregister is Germany's central official register for master data of the electricity and gas market, operated by the Bundesnetzagentur (Federal Network Agency). Operators of grid-connected solar systems and battery storage must register them online (there are no paper forms) shortly after commissioning; failure to register can jeopardise feed-in remuneration. Since the 2024 'Solarpaket I' reforms, small plug-in balcony solar systems only need to be entered in the MaStR rather than separately notified to the grid operator.
EEG feed-in tariff / market premium (Einspeisevergütung / Marktprämie)
Administered by: Federal framework set by law (Erneuerbare-Energien-Gesetz); remuneration paid by the local grid operator, with the Bundesnetzagentur overseeing and publishing the applicable rates
Under the EEG, operators of renewable-electricity systems are entitled to statutory remuneration for power fed into the public grid, either as a fixed feed-in tariff or, typically for larger systems, as a market premium that tops up revenue from selling electricity directly on the market. The local grid operator is legally obliged to connect the system and pay the applicable rate for a defined support period.
Who it is for: Operators of grid-connected renewable-electricity systems, including household rooftop photovoltaic systems and larger commercial or ground-mounted installations; the system must be registered and connected in line with EEG rules.
KfW Programme 270 – Erneuerbare Energien 'Standard'
Administered by: KfW (Kreditanstalt für Wiederaufbau, the federal promotional bank), applied for through a financing partner bank
A low-interest promotional loan for investments in renewable-energy generation, including photovoltaic systems on roofs, facades or open land, battery storage, and associated planning and installation costs. Applications are not made directly to KfW but through the applicant's own bank, and must be submitted before the project begins.
Who it is for: A broad range of applicants including private individuals, companies of any size, freelancers, farmers, non-profits and public bodies; private individuals generally must feed the generated electricity or heat into the grid.
Zero VAT rate for residential photovoltaics (Nullsteuersatz, § 12 UStG)
Administered by: Federal Ministry of Finance (Bundesministerium der Finanzen) / tax authorities; applied at the point of sale by the supplier or installer
A zero (0 percent) VAT rate applies to the supply and installation of qualifying photovoltaic systems and their essential components, including inverters and battery storage, so that eligible buyers pay no VAT on the system. The relief is applied automatically by the seller/installer rather than claimed back afterwards, and has no fixed expiry date.
Who it is for: Purchasers of qualifying photovoltaic systems installed on or near residential buildings and certain public and community buildings, up to the capacity limits defined in the law.
BAFA building & heating subsidies (Bundesförderung für effiziente Gebäude)
Administered by: BAFA (Bundesamt für Wirtschaft und Ausfuhrkontrolle, Federal Office for Economic Affairs and Export Control)
BAFA administers grant components of the federal building-efficiency scheme (BEG), which supports renewable heating measures such as solar thermal systems, as well as subsidised energy consulting. This is the main federal channel for solar thermal and heating-related support; direct grants for electricity-generating photovoltaics are instead delivered through the EEG, KfW financing and the zero VAT rate.
Who it is for: Owners of residential and non-residential buildings undertaking eligible renewable-heating or efficiency measures, and those seeking subsidised energy consulting; specific conditions and certification requirements apply.
Before you rely on any figure — check the official source
Solar incentive rates, tariff levels, budgets, eligibility thresholds and deadlines in Germany change frequently, and several schemes run on limited budgets or fixed application windows. This guide describes each programme at the mechanism level and links to the official administering body so you can confirm the current terms for your own project and year. Never commit to a purchase on the strength of a headline number from a third-party site — including this one.
Once you know which schemes apply, the practical next step is a qualified local installer who can size the system, handle the grid registration and apply for the incentives that fit. Browse solar companies in Germany → on Solar Directory.

Frequently Asked Questions
Do I need to register my solar system in Germany?
expand_more
Yes. Grid-connected solar systems and battery storage must be entered in the Marktstammdatenregister (MaStR), the central register operated by the Bundesnetzagentur. Registration is done online shortly after commissioning, and depending on system size the grid operator must also be involved for the grid connection. Small plug-in balcony systems benefit from a simplified process and generally only need the MaStR entry. Failing to register can put your feed-in remuneration at risk, so check the current registration rules and deadlines at the official source.
Can I combine different solar incentives?
expand_more
In general, mechanisms that address different aspects of a project can be combined, for example a KfW low-interest loan to finance the system, the zero VAT rate on its purchase, and EEG remuneration for electricity fed into the grid. However, the same cost normally cannot be funded twice, and each programme has its own conditions. Because combination rules can change, confirm what is compatible with each administering agency before you commit.
How do I claim the EEG feed-in tariff?
expand_more
Have the system installed and connected by a qualified installer, register it in the Marktstammdatenregister, and complete the grid-connection process with your local grid operator, which is then obliged to pay the statutory remuneration. Larger systems may instead use the market premium (Marktprämie) model, selling electricity directly and receiving a premium on top. The applicable rates are set under the EEG and are adjusted periodically, so check the current levels at the official source.
