Key points at a glance
For subsidies in the canton of Fribourg, these points matter most in 2026:
- Pronovo is the basis for standard PV.
- The city of Fribourg offers its own PV-related contributions; other municipalities must be checked separately.
- Cantonal subsidies often cover the building envelope, heating replacement or solar thermal energy.
- Groupe E and local utilities are important for feed-in, HKN and grid connection.
- Tax treatment and subsidy contributions must be checked according to Fribourg practice.
The specific subsidy always depends on address, system, building condition, grid operator, and deadlines of the respective program.

Subsidies 2026 in the canton of Fribourg
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 Fribourg
For standard photovoltaic systems in the canton of Fribourg, Pronovo is primarily relevant. Cantonal subsidy programmes in the reviewed sources focus mainly on building envelopes, heating replacement, and solar thermal energy.
Municipal programmes can make a difference. The city of Fribourg lists PV contributions as a share of the federal contribution; the conditions and maximum amounts should be checked directly with the city and Energiefranken before application or order.
Those who are renovating at the same time should consider cantonal building programme contributions and PV separately: not every energy-related contribution is automatically a PV contribution.
Municipal and energy supplier subsidies
In the canton of Fribourg, Groupe E is an important grid operator, alongside local utilities. Feed-in tariffs paid by the grid operator, HKN and solar power models should be checked with the relevant supplier.

Tax notes in the canton of Fribourg
For existing buildings, energy-related investments may be relevant for tax purposes; subsidy contributions must be taken into account when calculating the deduction. For new buildings, replacement new builds, and value-increasing measures, the classification should be clarified with the tax office or fiduciary body. There is no uniform 10-kWp tax-free threshold across Switzerland.
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 Fribourg
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 Fribourg
Many well-adapted roof systems are subject to notification. In protected landscapes, village centres, for protected objects, facade systems or agricultural zones, stricter requirements may apply in the canton of Fribourg. The ECAB should be involved for value-increasing photovoltaic systems and coverage questions.
In the canton of Fribourg, Kantonale Gebäudeversicherung Freiburg ECAB 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 Fribourg?
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 |
The decisive factor remains how well roof area, self-consumption, subsidies and the feed-in tariff paid by the grid operator work together.

Frequently asked questions
What subsidies for solar systems are available in the canton of Fribourg in 2026?
Nationally, the one-off payment via Pronovo (KLEIV/GREIV/HEIV) and from 2026 the winter electricity bonus for larger systems. Cantonal programmes focus on building renovation, heating replacement and consulting – specific contributions should be checked based on location.
Are there cantonal contributions in addition to the Pronovo subsidy?
This depends on the current programme. The main contribution for standard PV usually comes via the one-off payment; cantonal and municipal additional contributions are possible in specific cases. Overview: Energiefranken.
Is battery storage subsidised in the canton of Fribourg?
There is no comprehensive federal or cantonal subsidy for battery storage in 2026. Individual municipalities or energy suppliers may provide contributions – check via Energiefranken.
Are there municipal contributions for photovoltaics?
In some municipalities yes, with very different rates. Amounts and deadlines change; overview on Energiefranken.
Can I deduct a solar system for tax purposes?
For existing buildings, generally yes, as property maintenance. Subsidies received are deducted from the deductible amount. The cantonal tax office provides binding information.
Who helps with the subsidy application?
Your specialist installer usually handles the application to Pronovo on your behalf. Cantonal and municipal applications should be submitted by you or your installer in good time – before construction begins.
