EEG feed-in tariff
The EEG (Renewable Energy Sources Act) guarantees operators of PV systems fixed feed-in rates for the electricity they export for 20 years – a reliable foundation for any profitability calculation.

Funding for your energy transition
Germany supports renewable energy in many ways – from feed-in tariffs and low-interest loans to tax benefits. We give you the overview and, within your project, check what actually applies to you.
The funding landscape
These are the mechanisms you should know
The key building blocks of Germany's funding landscape for photovoltaics, storage and charging infrastructure – here as an overview, individually assessed within your project.
KfW loans
The KfW development bank offers low-interest loans for investments in renewable energy – for example PV systems, battery storage and charging infrastructure, applied for through your own bank.
BAFA programmes
Depending on the programmes available, the BAFA (Federal Office for Economic Affairs and Export Control) funds measures relating to energy efficiency and energy consulting – in some cases combinable with other building blocks.
Regional programmes
Federal states, districts, municipalities and sometimes grid operators or municipal utilities set up their own grant programmes – often time-limited and quickly exhausted. It pays to look closely.
0 % VAT
Under certain conditions, a zero VAT rate applies to the supply and installation of smaller PV systems on or attached to residential buildings – making the system noticeably more affordable.
Investment deduction (IAB)
Under certain conditions, businesses can claim planned PV investments as a profit-reducing deduction even before the purchase – we explain how this works on a dedicated page.
Go to IABImportant: Funding programmes, conditions and statutory rules change constantly – programmes launch, are adjusted or run out of budget at short notice. This page therefore describes only the basic mechanisms and does not constitute tax or legal advice. We assess individually within your project which funding is currently available for your plans and can be combined; please clarify tax questions with your tax advisor.
Our approach
Funding is not a matter of chance – it's part of the planning
The biggest mistake with funding: build first, ask later. Many programmes require the application to be submitted before placing the order – and some building blocks are mutually exclusive. That is why, for us, the funding review belongs at the start of every project, not the end.
- Funding research for your location: federal, state, municipal and grid operator level
- Assessment of which building blocks can be combined – and which cannot
- Profitability calculation with and without funding, so you can decide with confidence
- Support with documentation, proof of eligibility and deadlines
Rule of thumb for almost all grant programmes: apply first, then commission. Anyone who reverses the order usually loses their entitlement – regardless of how eligible the project would otherwise be.
Even without a grant, photovoltaics already pays off in many cases through saved grid electricity and the EEG feed-in tariff. Funding improves the calculation – but it is not a prerequisite for it.
