Overview
Overview
Pronovo is the reference body for photovoltaic support in Switzerland through the one-time remuneration scheme. This page is the main entry point for understanding the scheme, checking whether your project fits the right perimeter, and identifying the most useful next reading before opening an application.
Who is Pronovo relevant for?
Pronovo concerns sponsors of eligible photovoltaic projects in Switzerland. The scheme does not depend only on being the owner: the installation category, power, operating model and project timeline also influence the correct reading of the scheme.
How does the scheme logic work?
The one-time remuneration supports certain photovoltaic installations through an official logic that depends on the category selected, the technical characteristics of the installation and the conditions published by Pronovo. This parent page explains the general framework; more specific cases should be handled in the dedicated satellite pages.
What is the most logical next step?
If you first need to qualify the project, start with the solar photovoltaic project page. If your question is about estimation, the PRU / GRU / RUE category, documents or filing timing, continue afterwards with the guides and procedures linked to Pronovo.
Conditions
Main conditions
The project must first fall within a category officially supported by Pronovo. The applicable rules depend on the installation type, power, operating model and the exact filing timing.
Practical checks
- Confirm the official category before locking the technical configuration.
- Check the filing sequence that applies to the selected category.
- Align technical, administrative and timeline documents before submission.
- Confirm cumulation rules if cantonal or municipal support is also involved.
Cases that require caution
An installation close to a power threshold, a project change during implementation or an approximate category reading can change how the file should be assessed. When in doubt, go back to the current Pronovo documentation before making a binding decision.
Required documents
- Clear identification of the photovoltaic installation
- Technical documents required by Pronovo for the selected category
- Administrative evidence consistent with the application
- Items needed to verify the project timeline
- Proof of compliance and commissioning when the procedure requires it

Frequently asked questions
How does Pronovo work for PV?+
Pronovo manages the federal one-time feed-in remuneration (EIV). 2026 amount: base flat fee of about CHF 700 + CHF 300-600 per kWc installed. Example for 10 kWc: about CHF 3,700. Apply online after commissioning. Payment typically within 2-3 months of validation.
What are EIV, GEIV and HEIV?+
EIV: small systems < 100 kW, residential. GEIV: large systems ≥ 100 kW (businesses, agriculture). HEIV: systems from 2 to 149.99 kW WITHOUT self-consumption. The scheme is chosen automatically based on your profile.
Can I combine Pronovo with other solar aids?+
Yes. Several cantons add a cantonal top-up, and utilities (SIG Geneva, EWZ Zürich, Romande Énergie, IWB Basel) offer bonuses. In 2026, SIG Geneva raises its premium to 25% of the federal subsidy. Combined aid can cover 30-40% of installation cost.
