Solar subsidies in Switzerland: secure every entitlement

Key Takeaways

1. Up to CHF 270'000 from the Confederation The GREIV covers up to 30% of the investment: for a 500 kWp installation costing CHF 600'000–900'000, that means up to CHF 180'000–270'000. Bonuses and cantonal funding come on top depending on the system.
2. Bonus by mounting type From a tilt of 75 degrees, integrated system parts receive CHF 400/kW and attached ones CHF 200/kW, never both. Over previously uncovered car parks, systems from 100 kWp add CHF 250/kW.
3. Use cantonal surcharges Graubünden pays CHF 300/kWp for facades, Lucerne +20% on the federal EIV, Basel-Stadt CHF 140/m2 for facades with a simultaneous renovation. We systematically review every level for your site.
4. Winter electricity bonus from 2026 From January 2026, systems from 100 kWp producing over 500 kWh/kW in winter receive a federal contribution, as an alternative to the tilt angle bonus. Vertical PV reaches this threshold depending on the site.
5. No subsidy franc lost We file the GREIV application early, to secure a place on the waiting list and the assurance before construction. We handle the cantonal applications, coordination of all funding bodies and follow-up through to payout.

Most industrial companies capture less than 60% of the subsidies they are entitled to. Application deadlines, bonus structures and cantonal programmes are not coordinated, and money is left on the table. For a 500 kWp installation costing CHF 600’000–900’000, the GREIV alone covers up to 30% of the investment, or up to CHF 180’000–270’000 in one-time payments; bonuses and cantonal surcharges come on top depending on the system and location. Not as a promise, but as an individual calculation that we present to you before the first rafter is mounted.

Ampere Dynamic takes over complete subsidy coordination: from an early GREIV application with Pronovo through cantonal applications to payment follow-up. You focus on your core business; we focus on your subsidy volume.

Subsidy architecture: three levels that can be stacked

Since the Mantelerlass (68.7% referendum approval, June 2024, in force January 2025), Swiss funding has three cumulative levels. For industrial installations from 100 kWp, the GREIV (Grosse Einmalvergütung) via Pronovo AG is the central instrument, calculated individually by system type, capacity and commissioning date.

Two bonuses raise the payment for systems commissioned since January 2025:

• Tilt angle bonus for system parts tilted at 75 degrees or more: +CHF 400/kW for integrated modules (BIPV), +CHF 200/kW for attached or free-standing ones. The mounting type sets the rate; the same system part never gets both.
• Parking area bonus (+CHF 250/kW) for systems from 100 kWp over a permanent, previously uncovered car park

From January 2026, the winter electricity bonus (Winterstrombonus) is available: systems from 100 kWp producing over 500 kWh/kW in the winter half-year (October to March) receive CHF 2.50 per kW with or CHF 3.50 without self-consumption for each kWh/kW above the threshold, as an alternative to the tilt angle bonus, not on top of it. This favours facade PV, alpine installations and steeply tilted systems.

GREIV up to 30% for a 500 kWp installation, before bonuses and canton

Cantonal funding varies widely and deserves a close look: Lucerne pays a surcharge of around 20% on the federal EIV plus CHF 100/m2 for steep installations from a 75 degree tilt. Graubünden pays CHF 300/kWp for facade and vertical installations, one of the most generous cantonal programmes in Switzerland. Basel-Stadt funds facade PV with CHF 140/m2 and rooftop PV with CHF 100/m2 under its Aktion Solarkraftwerk Basel, in each case only with a simultaneous energy renovation of that facade or roof. Comparable facade bonuses exist in Glarus (CHF 250/kW), Obwalden and Uri. For your project, we systematically review all programmes on energiefranken.ch and with the responsible cantonal office.

At municipal level there are further options: individual municipalities fund carports, charging stations, ZEV installations or structural reinforcement, each with their own deadlines and budgets.

From eligibility check to payout

Our subsidy process

1

Check eligibility

We analyse your planned installation against all available funding programmes (federal, cantonal and municipal) and calculate the maximum subsidy volume before the contract is signed.

• GREIV calculation via the Pronovo tariff calculator
• Cantonal programmes via energiefranken.ch and the cantonal office
• Bonus combination: parking area bonus plus tilt angle or winter electricity bonus

2

GREIV and cantonal applications

The GREIV application can be filed before or after construction. Filing early secures a place on the waiting list and the assurance before construction, so we file it early, together with the cantonal applications.

• GREIV application via mein.pronovo.ch
• Cantonal applications submitted in parallel
• Complete final documentation after commissioning

3

Monitoring and follow-up

We monitor the subsidy status continuously and accompany you through to full payout. For large installations, the Pronovo review takes several months.

• Ongoing communication with all funding bodies
• Supporting documentation for queries
• Payout confirmation and final statement

Solar obligation and regulatory context

Since 1 October 2022, a solar obligation has applied to new buildings with a chargeable building area (anrechenbare Gebäudefläche) of more than 300 m² (Art. 45a EnG), for building applications from 1 January 2023.

Cantons that had introduced their own requirements under MuKEn 2014 Part E by 1 January 2023 are exempt and apply their own rules. Since January 2025 the obligation has been part of ordinary law in the Mantelerlass wording. The revised Energy Act with the Mantelerlass aims to increase solar power generation fivefold by 2035.

Since January 2025 the Climate and Innovation Act (KlG) requires every company to reach net-zero emissions by 2050 at the latest, covering at least its direct and indirect emissions (Art. 5 KlG). A published climate report, by contrast, is required only of public-interest entities (listed companies, banks and insurers) with 500 or more full-time employees, under the Code of Obligations (Art. 964a ff. CO). A company-owned PV installation reduces Scope 2 emissions directly and verifiably, in the net-zero roadmap and in the climate report alike.
