Are There Subsidies for Solar Panels in Germany?

Are there subsidies for solar panels in Germany? Yes, but they look different from what many guides promise. There are few classic grants. Instead there are several very effective benefits: no VAT on purchase, tax-free income, a feed-in tariff guaranteed for 20 years, low-interest KfW loans and regional programmes such as proKlima in Hanover. There is also an important deadline: the EEG amendment 2027 changes the rules for new small systems. Here is an overview of all funding options.

Solar Subsidies in Germany at a Glance

• 0 % VAT: since 2023, the purchase and installation of PV systems and battery storage on residential buildings is VAT-free (zero rate). Details in our guide to photovoltaic system VAT.
• Tax-free income: income from systems up to 30 kWp per residential or commercial unit is exempt from income tax, see tax-free photovoltaic system.
• EEG feed-in tariff: a fixed rate for 20 years for electricity fed into the grid. Since 1 August 2026, about 7.70 ct/kWh (surplus feed-in) or 12.22 ct/kWh (full feed-in) for systems up to 10 kWp. All rates and rules in our article on the EEG law for photovoltaics.
• KfW loan 270: low-interest financing for PV systems and storage.
• Regional grants: in and around Hanover, for example proKlima, see solar funding in Hanover.

Deadline 31 December 2026: What the EEG Amendment 2027 Means

On 29 July 2026, the federal cabinet approved the EEG amendment 2027. For new rooftop systems under 25 kW, the permanent fixed feed-in tariff is to be replaced from 2027 by a temporary transition payment followed by direct marketing. Existing systems and all systems commissioned by 31 December 2026 keep their tariff for the full 20 years. Parliament, the Federal Council and the EU Commission still have to approve the law. Full details and an example calculation are in our article on the EEG amendment 2027.

Important for planning: what counts is the commissioning date, not the order date. Grid registration and meter installation often take several weeks, so a project aiming for 2026 should start now.

KfW Funding: Loan 270 “Renewable Energies – Standard”

KfW does not support PV systems and battery storage with grants, but with the low-interest loan 270. It is open to private individuals, companies and municipalities and is applied for through your bank. Important:

• The application must be made before the project starts, i.e. before you sign a binding contract.
• It finances the investment costs for the system, storage and installation.
• Whether the loan pays off depends on the current interest rate compared with your own bank. Many buyers use their own funds, since the zero VAT rate already makes the purchase cheaper.

Tax Benefits: The Biggest Advantage for Homeowners

Today the most effective support is in the tax system. The zero VAT rate saves you the 19 % VAT that used to apply to the system, storage and installation, several thousand euros for a typical 10 kWp system with battery. In addition, income from feed-in and self-consumption is free of income tax for systems up to 30 kWp per unit, and under the small business scheme no VAT is charged on the feed-in tariff either. For most homeowners this means hardly any paperwork with the tax office.

Regional Programmes in Hanover and Lower Saxony

Regional grants are the only type of funding where you actually receive extra money. In the Hanover region, the most relevant is the proKlima climate fund: its DachVollToll programme supports PV systems that use as much of the roof as possible in Hanover, Hemmingen, Laatzen, Langenhagen, Ronnenberg and Seelze. According to proKlima, applications for 2026 are possible until 31 October 2026. Conditions and how to apply are explained on our page about solar funding in Hanover.

Outside this region, check the federal funding database (foerderdatenbank.de), your state development bank, and your city or local utility. These programmes change often, have limited budgets and almost always have to be applied for before you place an order.

Are There Subsidies for Battery Storage?

There is currently no nationwide grant for private battery storage. However, batteries benefit from the zero VAT rate, can be financed through the KfW loan 270 and are sometimes subsidised by municipalities. With the EEG amendment 2027, storage becomes even more important economically, because returns shift further towards self-consumption. See our comparison of the best battery storage systems.

Subsidies for Balcony Solar Systems

Balcony solar systems are also sold without VAT. Some cities and municipalities pay a small additional grant, but these programmes are usually used up quickly. A feed-in tariff plays practically no role for balcony systems, as they are designed for self-consumption.

How to Apply for Solar Funding Correctly

1. Check funding before you sign: the KfW loan and most municipal grants must be applied for before a binding order. Late applications are usually rejected.
2. Prepare documents: usually the quote or cost estimate, technical data sheets and details about the building.
3. Wait for approval, then place the order and have the system installed.
4. Register the system: with the grid operator and in the Market Master Data Register within one month of commissioning, a requirement for the feed-in tariff.
5. Submit proof: invoice, commissioning report and, if required, photos. Only then is a grant paid out.

A concrete example for a 10 kWp system is in our guide to applying for 10 kWp funding.

Common Mistakes with Solar Funding

• applying too late, by far the most common mistake
• overlooking double-funding rules: not every programme can be combined with others
• incomplete documents or missed deadlines
• forgetting the Market Master Data Register: no entry, no feed-in tariff
• planning commissioning too late, especially with the 31 December 2026 deadline

Conclusion: Make Targeted Use of Funding

Solar funding in Germany today consists less of grants than of tax and tariff benefits, and for most homeowners these are worth several thousand euros. If you commission your system by 31 December 2026, you also secure a fixed feed-in tariff under current law for 20 years.
