Schaffhausen has several PV-related special topics in 2026: battery storage, bidirectional charging, special projects and renovation combinations. For the standard PV system, Pronovo is important; the cantonal additional points mainly concern self-consumption and particular project types.
Key points at a glance
For subsidies in the canton of Schaffhausen, these points matter most in 2026:
- Pronovo is the national basis for standard PV.
- Schaffhausen provides contributions for battery storage in grid-connected solar systems.
- Bidirectional charging stations with PV and special projects such as Agri-PV/solar parking lots may be relevant.
- SH POWER, EKS and local utilities determine feed-in and HKN.
- Permits and insurance need to be clarified early on for border region, commercial, and special projects.
The specific subsidy always depends on address, system, building condition, grid operator, and deadlines of the respective program.

Federal subsidy 2026 at a glance
For photovoltaic systems, there are one-off payments nationwide via Pronovo. The most important instruments are:
- KLEIV - One-off payment for systems with less than 100 kW capacity.
- GREIV - One-off payment for systems of 100 kW or more.
- HEIV - high one-off payment for systems without self-consumption from 2 kW to 149.99 kW.
- Auctions and other instruments - for larger systems without self-consumption, auctions, the sliding market premium or other subsidy instruments may apply depending on the project.
- Additional bonuses - depending on the system, winter electricity, tilt angle, or parking area bonuses may be relevant.
Deadlines are not the same for all instruments. The KLEIV is generally applied for after commissioning. For GREIV, HEIV, auctions as well as cantonal or municipal programmes, other deadlines may apply; they should be checked before ordering or starting construction.
Cantonal subsidies in the canton of Schaffhausen
In the canton of Schaffhausen, not only the standard PV subsidy via Pronovo is relevant in 2026. The cantonal funding programme includes special contributions related to PV, such as for battery storage with grid-connected solar power systems and for bidirectional charging stations with a coupled PV system.
Additionally, special projects such as agri-photovoltaics or solar car parks, as well as renovation combinations with solar power systems, may be eligible for subsidies. These contributions are subject to conditions and, in some cases, minimum contributions or investment costs.
For standard roof-mounted systems without storage, charging infrastructure or a special project, Pronovo is the main subsidy; the municipality and grid operator should be checked additionally.
Municipal and energy supplier subsidies
In Schaffhausen, SH POWER, EKS and local utilities are relevant. Feed-in tariffs paid by the grid operator, HKN, grid connection and green electricity models should be checked on a site-specific basis.
Tax notes in the canton of Schaffhausen
Tax deductions for energy-related investments must be assessed through the Schaffhausen tax administration and the specific property situation. Subsidies reduce the costs borne by the owner. The distinction is important for new builds, replacement new builds, and value-adding components. There is no uniform nationwide tax-free threshold of 10 kWp.
Important: Feed-in remuneration, self-consumption and subsidies are treated differently depending on cantonal tax practice. Therefore, larger systems, new builds and special cases should be clarified in advance with the tax office or fiduciary.
Feed-in remuneration and feed-in tariffs in the canton of Schaffhausen
Feed-in tariffs paid by the grid operator are not uniform across cantons; the specific grid operator is decisive. From 2026 onwards, if no agreement is reached between the grid operator and the system operator, the quarterly reference market price calculated by the federal government applies. Minimum remuneration rates exist for photovoltaic systems under 150 kW; for systems up to 30 kW, this rate is 6 Rp./kWh. Certificates of origin, local green electricity models and specific grid operator tariffs must be checked separately. Details on the page Feed-in Remuneration Switzerland.
Economically, self-consumption remains central. For apartment buildings, sites, and mixed-use buildings, ZEV, vZEV, and from 2026 local electricity communities (LEG) should be considered. A LEG is not an automatic return guarantee, but a new option that must fit the project technically, legally, and economically.
Permits and insurance in the canton of Schaffhausen
Many adapted roof systems are subject to notification requirements. For old town/village landscape protection, facade installations, freestanding systems, agricultural zones, or special projects such as agri-PV, a specific construction clarification is required. The cantonal building insurance should be contacted regarding photovoltaic systems that increase the value of the property and questions about coverage.
In the canton of Schaffhausen, Kantonale Gebäudeversicherung Schaffhausen is relevant for building insurance. Owners should clarify whether the photovoltaic system, a roof renovation and any battery storage are correctly taken into account in the sum insured and coverage.
Who benefits most from photovoltaics in the canton of Schaffhausen?
Typical situations can be categorised for this canton as follows:
| Situation | Assessment |
|---|---|
| Single-family home with a good roof | Often worth checking, EIV + tax deduction have a strong effect |
| Heat pump present or planned | Self-consumption particularly valuable |
| E-car present or planned | Charging times matter, EMS is worthwhile |
| Apartment building / condominium ownership | Check ZEV, vZEV and LEG from 2026 onwards |
| Commercial / Agriculture | Daily consumption often matches well with solar production |
| Small or shaded roof | Get an exact calculation |
What remains decisive is how well roof area, self-consumption, subsidies, and feed-in tariff paid by the grid operator work together.
Checklist before the quote
Before requesting a quote, this information should be available so that the subsidy and cost-effectiveness can be checked properly:
- Address, municipality and grid area determine
- Check roof area, orientation, pitch and shading
- Calculate system size in kWp and expected annual/winter yield
- Check Pronovo instrument: KLEIV, GREIV, HEIV or for large systems auction/GMP
- Schaffhausen: Check storage, bidirectional charging and special projects
- Check subsidy deadlines for each programme: KLEIV usually after commissioning, local programmes often earlier
- Tax deduction: separate existing building, new build/replacement new build and subsidy contributions
- Check the feed-in tariff paid by the grid operator, HKN and any possible green electricity models with the grid operator
- Realistically calculate self-consumption, battery storage, heat pump, electric car, ZEV/vZEV and LEG
- Clarify permit, protected objects, building insurance and any private additional coverage
With this information, the specialist installer can assess subsidy, self-consumption and technical design significantly more robustly.
