Photovoltaic subsidisation
Having your own solar system on the roof with self-generated electricity that is used in the household is something that more and more homeowners are striving for. Not only can you save a lot of money, but your own environmental footprint also looks much better with your own green electricity. However, financing is often an issue that concerns many people, especially when it comes to larger photovoltaic systems (PV systems). Here you will find everything you need to know about photovoltaic subsidy options.
Subsidy for your own solar energy system: what subsides are available?
Subsidies for solar energy systems have become increasingly numerous in Germany in recent years. On the one hand, this is due to a growing willingness among the population to adopt a climate-friendly lifestyle and, on the other, to the efforts of the German government to make environmentally friendly alternatives to electricity generation more attractive and affordable. Both of these factors play into the hands of homeowners. When planning your PV system, you have the choice between various models — from loans with low interest rates to one-off government grants. In addition, the EEG (Erneuerbare-Energien-Gesetz: Renewable Energy Sources Act) is intended to promote the expansion of photovoltaics. The law was reformed in 2023, so that now
- operators of PV systems can now feed their energy into the public grid without restriction, provided the system does not have a capacity of more than 7kW or has a metering system up to 25kW.
- consumers are no longer charged an EEG surcharge.
Our tip: Find out about current subsidies for solar systems from your city or local authority, as larger and smaller packages are always being put together in many federal states.
KfW 270 – Subsidy for photovaltaics
KfW (Kreditanstalt für Wiederaufbau) is a German development bank that grants loans on behalf of the federal and state governments to promote the economic, ecological and social development of the country. Companies as well as public institutions and private individuals are eligible for funding. Funding can be applied for both for projects in Germany and abroad. The financing programme for energy-efficient construction and renovation also includes funding for PV systems. The Renewable Energies — Standard subsidised loan 270 for electricity and heat is just the thing for anyone who wants to turn their dream of generating their own solar power into reality. It provides you with extensive funding for photovoltaic systems on roofs, façades or open spaces.
Requirements and conditions for KfW 270
The following requirements must be met in order to receive funding for photovoltaics from KfW:
- The application must be submitted before the solar system is purchased and installed. Investments in PV systems that have already been started or even completed are no longer eligible.
- The minimum term of the loan is two years.
- The photovoltaic subsidy must be applied for via a KfW financing partner. This can be a bank or savings bank in your neighbourhood, for example. The advantage of this concept is that you always have a local advisor available if you have any questions.
- The loan is concluded with an effective annual interest rate from 5.21%.
- There must be a partial or full feed-in of the solar power generated.
When planning your rooftop PV system, you should decide as early as possible whether you want to apply for a subsidy. You may apply for a loan from a KfW financing partner at an early stage. You will need as much detailed information as possible about your project. This includes:
- Desired loan amount
- Desired loan term incl. redemption-free years and fixed interest period
- Date of your planned investment (must be in the future!)
- Some personal and demographic data
If you are worried about high costs for the purchase and installation, you can rest assured: it is not absolutely necessary to include your own capital for the financing. However, KfW advises you to use your own funds, as this allows you to prove your creditworthiness and benefit from more favourable conditions.
In the second step of the application, you need to provide technical information about the project. This includes, for example, the size of the system in m² and kWp (kilowatt peak) as well as the expected amount of electricity generated. You should only fill in this section once you are able to provide all the final, correct and complete details. It is best to seek advice from your local financing partner.
BAFA subsidy: Is photovoltaics subsidised?
The BAFA (Bundesamt für Wirtschaft und Ausfuhrkontrolle: Federal Office of Economics and Export Control) subsidises renovation measures that increase the energy efficiency of a building through the use of renewable energies. This also includes funding for solar thermal systems with a subsidy of 25 %. This BAFA subsidy therefore only applies to systems consisting of solar collectors. In contrast to PV systems with solar cells, solar collectors convert energy into heat. A BAFA subsidy for photovoltaic systems that convert energy into electricity is unfortunately not yet available.
However, there is full government support for PV systems in the form of the KfW loan, the feed-in tariff, the tax relief for homeowners that came into force on 1 January 2023 and the solar packages from the BMWK (Federal Ministry of Economics and Climate Protection). The latter significantly reduces bureaucratic and technical hurdles in the expansion of renewable energies. Apart from this, you can always consult your federal state or local authority to find out which subsidies and funding are currently available for photovoltaics on your own roof.
Subsidy for photovoltaic systems of federal states and municipalities
If you would prefer a photovoltaic grant that does not have to be repaid instead of a loan-based subsidy, some federal states and local authorities offer subsidies. We would like to recommend that you check regularly and only on trustworthy websites. Although various advice blogs on the subject of renewable energies and providers of PV systems provide information on local subsidies, they often give contradictory or outdated information. Generally, the ever-increasing number of subsidies for photovoltaics and other sustainable energy generation methods are published well in advance on the official website of your municipality, city or federal state. In Berlin, for example, “SolarPLUS” is one of the most extensive projects for the promotion of photovoltaics for both private and commercial interests.
Another current topic is tenant electricity projects. These enable landlords to generate solar power on the roof of their residential building, which can be used directly by the tenants without being fed through the grid. This saves the costs of external electricity and grid fees. In order to make this model attractive to owners of residential buildings, the 2017 Renewable Energy Sources Act (EEG) includes a subsidy for the use of photovoltaic electricity in the form of a tenant electricity surcharge for non-feed-in. Further information on the topic of tenant electricity can be found on the BMWK’s Renewable Energies information portal.
Apart from this, there is a feed-in tariff for solar energy from your own roof throughout Germany. However, this has so far been rather low and is often only worthwhile for operators of larger PV systems who do not want to use the self-generated electricity in their own household, or only partially.
Which photovoltaic subsidy is right for me?
Depending on the scope of your PV system plans, when you want to start and what equity capital you have, you can find the best solution for your project from the solar system subsidy options.
Immediate solution with repayment obligation: KfW subsidy
If you would like to start the energy transition in your own household right away and are also prepared to invest in your own climate-friendly future, you can’t go wrong with KfW 270 funding. Here, solvent and creditworthy customers have the opportunity to quickly and easily receive up to €150 million in funding for photovoltaics from a KfW partner bank. This is more than enough for private individuals whose average expenditure for a PV system on the roof is between €10,000 and €50,000. You can easily repay your green loan at favourable conditions over a period of your choice (minimum 2, maximum 30 years). The savings on electricity consumption make this an attractive solution for many people who have a private home.Photovoltaic subsidy from the state
When applying for a subsidy for a PV system, you can rely on the current subsidy programmes in your region. If no funds are currently available, you will have to be patient — or do without a subsidy. However, if there are subsidies for photovoltaics in your federal state or district, this option is just as easy as a loan. The advantage: you do not have to pay back the subsidy. One possible disadvantage is that the subsidies are often not very high and only cover a small proportion of the costs. Nevertheless, a subsidy from the federal or state government is a good way to equip your home with environmentally friendly electricity from your own roof and save a few hundred euros on the purchase and installation.Combination of subsidised loan and one-off funding
A combination of subsidy and loan is also possible: you then benefit from small but generous one-off payments and large loan amounts with favourable interest rates. With this combination, you can apply for a comprehensive photovoltaic subsidy and realise your dream of living with climate-friendly electricity quickly, safely and at a reasonable price.
