Why is it worth investing in photovoltaics?

Sustainable returns: Photovoltaic systems benefit from long-term stable sources of income through feed-in tariffs, the sale of solar power on the open market or through energy savings from own use. Average returns vary depending on the location, size of the system and subsidy conditions, but can be significantly attractive.

Environmentally friendly: The transition to photovoltaics is a decisive step towards reducing the carbon footprint. Every kilowatt hour of solar power reduces CO2 emissions compared to conventional power generation.

Energy independence: For companies in particular, using their own solar systems means a significant reduction in energy costs and less dependence on rising electricity prices.

Technological advances: The efficiency of solar cells is continuously improving, while the cost of installing solar systems is falling, making the investment increasingly accessible and profitable.

Positive market development: In view of global efforts to combat climate change, there is strong growth in the solar sector. This is creating high demand for photovoltaic systems and increasing their value as an investment.

What are the costs of a photovoltaic system?

The cost of a photovoltaic system (PV system) can vary considerably depending on a number of factors. These include the size of the system (measured in kilowatts peak, kWp), the quality of the components used (solar panels, inverters, etc.), the complexity of the installation (e.g. roof pitch, orientation, accessibility) and regional price differences. As of April 2023, however, some general guide values can be given to provide an initial cost estimate:

  • Smaller systems for single-family homes

    For smaller photovoltaic systems with an output of up to 10 kWp, which are typically installed on single-family homes, the average total costs in Germany are between EUR 1,200 and EUR 1,700 per kWp of installed output.

    A typical system of this size (e.g. 5 kWp) would therefore cost around 6,000 to 8,500 euros.

  • Larger systems

    For larger photovoltaic systems, such as those installed on apartment blocks or for commercial purposes, the costs per kWp can be lower due to economies of scale.

    For systems over 10 kWp, the cost per kWp can fall to around €1,000 to €1,500.

  • Additional costs

    In addition to the purchase costs of the system, there may be additional costs depending on requirements, for example for the integration of an energy storage system so that the self-generated solar power can also be used after sunset. Such storage systems can significantly increase the overall costs, but also offer the opportunity to increase the self-consumption rate and thus the economic efficiency of the system.

    Other possible additional costs may arise from the need to reinforce the roof, replace old electrical installations or install a more sophisticated substructure in difficult roof conditions.

  • Subsidies and savings

    The investment costs can be reduced by government subsidies, such as low-interest loans or direct grants. The possibility of feeding solar power into the public grid and receiving remuneration for this also improves the amortisation calculation.

    In the long term, the operation of a photovoltaic system leads to savings in electricity costs, which must be offset against the initial investment. The amortisation period for a PV system in Germany is often between 8 and 15 years under optimum conditions and taking into account the current subsidy mechanisms.

As prices for components and installations vary and government subsidy programmes can change, it is advisable to obtain several quotes and research the latest information on subsidy options before investing in a photovoltaic system.

How are photovoltaic systems subsidised?

Germany offers a variety of funding programmes and incentives for investments in solar energy and photovoltaics. These support programmes aim to promote the expansion of renewable energies in line with Germany's climate targets. However, the specific subsidy conditions may change, so it is important to obtain up-to-date information directly from the relevant authorities or via official information portals. Here are some of the core subsidies and incentive programmes on offer in Germany:

  • Feed-in tariff

    The Renewable Energy Sources Act (EEG) regulates the feed-in tariff for electricity from renewable sources, including solar power. Operators of photovoltaic systems receive a fixed remuneration for the electricity they feed into the public grid. The remuneration rates are regularly adjusted and are generally guaranteed for new systems for 20 years, which offers long-term planning security.

  • EEG levy exemption

    For self-consumed electricity from photovoltaic systems, an exemption or reduction from the EEG levy can be claimed under certain conditions. This reduces the cost of self-consumed solar power and makes self-consumption more attractive.

  • KfW promotional programmes

    The Kreditanstalt für Wiederaufbau (KfW) offers various promotional programmes for photovoltaic investments. These include low-interest loans and grants for the installation of solar systems on residential buildings, companies and municipal facilities. Some KfW subsidies also support storage integration in order to maximise the use of self-generated solar power.

  • Tax incentives

    Investors can benefit from tax incentives such as the amortisation of investment costs (AfA) or the VAT exemption for small businesses. In addition, operators of photovoltaic systems may be able to sell the electricity generated subject to VAT and claim input tax deduction for the investment costs.

  • Regional funding programmes

    In addition to nationwide funding, many federal states and local authorities offer their own support programmes. These can include grants, subsidised loans or other financial incentives and are often tailored to specific target groups or project types.

The funding landscape is dynamic and programmes can change or expire. It is therefore crucial to research the latest information on subsidy programmes before planning a photovoltaic system. The Federal Network Agency, the Federal Ministry for Economic Affairs and Energy (BMWi) and the KfW are good places to go for up-to-date information on subsidy programmes and conditions in Germany.

What documents do we need for your photovoltaic project?

In order to make an initial assessment of your solar power project, we need the following documents:

  • Exposé of your project with details of the borrower and the plant location

  • Your planned investment costs

  • Information on the remuneration rate and planned energy yield

  • Statement of expected operating and administrative expenses

  • Timing from loan offer to grid connection

  • Your desired financing structure with loan amount and term

5 important questions about your photovoltaic project

  • Energy cost savings: Reduces electricity bills in the long term by utilising the electricity you generate yourself.

  • Environmentally friendly: Produces clean, renewable energy and reduces the CO2 footprint.

  • Independence: Increases energy independence from external electricity suppliers and price fluctuations.

  • Value enhancement: Can increase the value of the property.

Returns can vary, but average projects generate around 4% to 8% returns annually, depending on the location, size of the plant, costs and subsidy conditions.

Photovoltaics is considered a relatively safe investment as it is based on established technology, offers predictable long-term income through feed-in tariffs or energy savings and is less volatile than other forms of investment.

Yes, photovoltaics is subsidised by the state through feed-in tariffs, tax benefits, low-interest loans and special programmes at federal and state level.

Photovoltaics has significant environmental benefits as it helps to reduce greenhouse gas emissions, replaces fossil fuels and utilises a sustainable, inexhaustible energy source. finds the right financier for you
