The Canton of Schwyz doesn't pay a cantonal incentive contribution for photovoltaics – unlike for thermal solar systems. That sounds sobering, but it's only half the story: the most important incentive comes from the federal government anyway, via the one-off feed-in incentive (Pronovo), plus the tax deduction, and individual municipalities can add to it. At the end of the day, a system in the Canton of Schwyz still adds up solidly – just via the federal government and taxes instead of a cantonal pot. (As of: July 2026)
Key points in brief
- The Canton of Schwyz doesn't support photovoltaics with a cantonal contribution (thermal solar systems may be treated differently).
- The main incentive is the federal one-off feed-in incentive via Pronovo – independent of canton.
- For tax purposes, the investment counts as property maintenance and is deductible from income.
- Incentive contributions received are deducted from the deductible amount.
- Individual municipalities may have additional contributions – checkable via energiefranken.ch.
Does the Canton of Schwyz pay for my solar system?
No – there is no cantonal incentive contribution for a classic photovoltaic system in the Canton of Schwyz. The canton concentrates its energy incentives on other measures; thermal solar systems (solar thermal for heat generation) may be treated differently here than electricity production with photovoltaics. This isn't a special case: several cantons forgo their own PV incentive because the main incentive comes from the federal government anyway.
But that doesn't answer the question «incentives in the Canton of Schwyz», it just shifts it – to the level that really counts: the federal government and taxes. The article Incentives for solar systems in Switzerland provides the overall overview of all incentive pots in Switzerland.
Where does the incentive come from then?
From two reliable sources that apply in the Canton of Schwyz just as everywhere else:
The federal one-off feed-in incentive (EIV). That's the most important contribution – a one-off investment grant handled by Pronovo, open to practically every roof system. How it's made up and how high it is is explained in the article One-off feed-in incentive explained; registration is covered in Pronovo registration. This incentive is independent of canton – whether Schwyz, Zurich or Zug, the federal government pays the same.
The tax deduction. For tax purposes, investing in a photovoltaic system on an existing building counts as a value-preserving measure (property maintenance) and can be deducted from taxable income – for both cantonal and federal tax. Note: incentive contributions received (such as the one-off feed-in incentive) are deducted from the deductible amount. The article Solar system and tax deduction explains the system.
And the municipalities in the Canton of Schwyz?
What the canton doesn't pay, a municipality may possibly add – that's a patchwork and changes constantly. Instead of naming figures here that would be outdated tomorrow, one reliable path leads to the goal: the platform energiefranken.ch. There you enter your postcode and see the contributions currently available for private individuals in your municipality – both cantonal and municipal.

Overview, as of: July 2026. The current regulations of Pronovo, the Canton of Schwyz and your municipality, as well as the applicable tax practice, are authoritative.
And one more financial aspect that has nothing to do with incentives but belongs in the overall calculation: the remuneration for the electricity fed in. In the Canton of Schwyz this depends on the local grid operator – for the EW Höfe area, for instance, this is covered in the article Feed-in tariff EW Höfe.
«The Canton of Schwyz pays nothing for solar» – clients sometimes hear this sentence and are discouraged. We then put it into perspective: the biggest chunk of the incentive is the federal one-off feed-in incentive, and that exists here just as everywhere else. Plus the tax deduction, which noticeably affects many households. What we always recommend: before the tax return, briefly clarify with the tax office or accountant how the deduction is specifically declared in the Canton of Schwyz – for instance, whether the costs can be spread over several years. That's a detail that can amount to a few hundred francs depending on the situation. In terms of incentives, Schwyz isn't a bad place for a solar system – you just need to know which doors to knock on.
Frequently asked questions
Is there a cantonal incentive for photovoltaics in the Canton of Schwyz?
No, the Canton of Schwyz doesn't pay its own incentive contribution for photovoltaics. The main incentive comes from the federal government via the one-off feed-in incentive (Pronovo), which applies regardless of canton. Thermal solar systems for heat generation may be treated differently than electricity production with photovoltaics.
Is a solar system still worthwhile in the Canton of Schwyz?
Yes. The most important incentive – the federal one-off feed-in incentive – exists here just like everywhere, plus the tax deduction. The fact that the canton doesn't pay its own contribution changes little about the fundamental profitability, because the federal share makes up the largest part anyway.
Can I deduct the solar system from taxes in the Canton of Schwyz?
Yes. The investment on an existing building counts as a value-preserving measure and is deductible from taxable income, for both cantonal and federal tax. Incentive contributions received are deducted from the deductible amount. The specific declaration is best clarified in advance with the tax office or an accountant.
Does my municipality in the Canton of Schwyz pay anything?
Possibly – individual municipalities have additional contributions, but this is inconsistent and changes constantly. The most reliable way is the platform energiefranken.ch: enter your postcode and check the contributions currently available for your municipality.
