Frequently asked questions

How high is the winter electricity subsidy in Graubünden?

The program pays CHF 300 per kWp, a minimum of CHF 900 and a maximum of CHF 200,000. It applies to suitable systems with a 60–90° inclination, suitable orientation, more than 1250 kWh/m²a global radiation and at least 3 kWp.

What slope does my system need for winter power?

The relevant inclination is 60–90°. In addition, the program checks the orientation from east to south to west, global radiation of more than 1250 kWh/m²a and the minimum power of 3 kWp.

What is the funding for area potential?

Area potential is funded at CHF 150 per kWp, a minimum of CHF 450 and a maximum of CHF 50,000. The system must exceed the calculated internal consumption of 20 W/m² EBF by at least 50% and at least 3 kWp.

Can I combine winter electricity and area potential?

No. The two cantonal PV programs cannot be combined with one another. Choose the funding method that best meets the requirements of your project and check for additional public contributions below the statutory 50% limit.

Is there an obligation to generate your own electricity for new buildings in Graubünden?

Yes. For new buildings, there is a separate obligation to produce your own electricity of 10 W/m² energy reference area, a maximum of 30 kW. This is not the same as the 20 W/m² calculation of the area potential program and is not automatically a blanket PV obligation.

Can I also purchase Pronovo?

Pronovo is the federal level and must be checked separately for the specific system; According to the FAQ, the regular one-off payment applies from 2 kW. Additional federal bonuses have their own requirements and may not be added to a guaranteed total without checking.

What funding limit do I have to consider?

Cantonal contributions and other public contributions together may not exceed 50% of project-related expenses. That's why CHF 300/kWp, CHF 150/kWp, Pronovo and possible bonuses are not easy to add up.

What does the threshold of 20 W/m² EBF mean?

20 W/m² EBF is the calculated own requirement that the Area Potential program uses for its threshold. A system that exceeds this value by at least 50% and additionally by at least 3 kWp is eligible for funding; The statutory requirement for new construction, however, is 10 W/m² EBF and a maximum of 30 kW.

Which global radiation applies to the two programs?

For winter electricity and area potential, global radiation must generally be more than 1250 kWh/m²a. In simple terms, global radiation describes how much solar energy arrives at the location per square meter per year.

How long is the assurance valid?

There is generally a period of 3 years to guarantee the winter electricity program. It can be extended for a maximum of 2 years; The specific decision remains decisive.

Do I need a building permit for a subsidized facility?

This cannot be answered from the funding program alone. Clarify with the municipality which construction method applies to the location, design and any protection interests; The funding commitment does not replace a building permit.
