Short answer

In the Canton of Schaffhausen, the federal one-off feed-in incentive (via Pronovo) is the central incentive for photovoltaics. The canton runs an energy incentive programme, and individual municipalities – including the City of Schaffhausen and Thayngen – grant additional contributions, which are applied for automatically via the cantonal application procedure. On top of that there's the tax deduction: the investment counts as property maintenance and can be deducted from income, spreadable in the Canton of Schaffhausen over up to three tax years. (As of: July 2026)

What incentives are available in the Canton of Schaffhausen?

As everywhere in Switzerland, the most important incentive is the federal one-off feed-in incentive (EIV) – a one-off investment grant handled by Pronovo. For small systems (KLEIV) and larger ones (GREIV), it covers part of the investment costs. How it's made up is explained in the article One-off feed-in incentive explained, and registration is covered in Pronovo registration. This incentive exists in the Canton of Schaffhausen just as everywhere else.

In addition, the Canton of Schaffhausen runs an energy incentive programme, adjusted slightly each year. The article Incentives for solar systems in Switzerland provides the overall overview of the incentive landscape in Switzerland.

Do the municipalities in the Canton of Schaffhausen contribute anything extra?

Yes – and this is the Schaffhausen speciality: individual municipalities grant additional incentive contributions for photovoltaics. Known examples are the City of Schaffhausen and the municipality of Thayngen. The practical part: these municipal contributions are usually applied for automatically via the cantonal application procedure – so you don't have to approach several offices separately.

Because the specific amounts and conditions change constantly, we deliberately don't state figures here that would be outdated tomorrow. Two sources provide the current status for your address: the Canton of Schaffhausen's energy office and the platform energiefranken.ch, where you can see the available contributions via your postcode.

Overview, as of: July 2026. The current regulations of Pronovo, the Canton of Schaffhausen and your municipality, as well as the applicable tax practice, are authoritative.

How does the tax deduction work in Schaffhausen?

For tax purposes, investing in a photovoltaic system on an existing building counts as a value-preserving measure (property maintenance) and is 100 percent deductible from taxable income – for both cantonal and federal tax. A special feature relevant for Schaffhausen: the costs can be spread over up to three consecutive tax years. This can increase the tax saving if the investment exceeds income in a single year. The basic system – including the rule that incentive contributions received are deducted from the deductible amount – is explained in the article Solar system and tax deduction.

And besides the incentives, the overall calculation also includes the remuneration for the electricity fed in – in the Canton of Schaffhausen via the local grid operator. This is covered in the article Feed-in tariff EKS.

From practice

Schaffhausen is a good example of how incentives can't be read off from a single page. The federal government pays the one-off feed-in incentive, the canton runs its programme, and individual municipalities add a bit more – the City of Schaffhausen and Thayngen, for instance. The nice part: the municipal contributions run through the cantonal application, so you don't have to knock on three doors. What we always advise clients: don't forget to spread the tax deduction over several years – especially in Schaffhausen, where up to three years are possible, you get more out of it this way. We take care of the Pronovo registration and point out the municipal level; the tax declaration itself is best discussed with your accountant.

Frequently asked questions

Is there an incentive for photovoltaics in the Canton of Schaffhausen?

Yes. The main incentive is the federal one-off feed-in incentive via Pronovo. The canton runs an energy incentive programme, and individual municipalities – such as the City of Schaffhausen and Thayngen – grant additional contributions, which are applied for automatically via the cantonal application procedure. You can check the current amounts via the energy office or energiefranken.ch.

Do I have to apply for the municipal incentive separately?

Usually not. The additional municipal contributions are applied for jointly via the cantonal application procedure. This simplifies the process – you submit one application instead of approaching several offices separately. The canton's energy office can confirm the exact procedure.
