Short answer
Do I need a building permit for a ground-mounted PV system in Fribourg?
Ground-mounted PV in Fribourg is mainly relevant for open land, car parks and slopes within a building zone. The current Fribourg information sheet describes a simplified procedure, ideally for areas above 1,000 m², and Pronovo support of up to 60% for large systems without self-consumption. Different spatial-planning rules apply outside the building zone.
Important
As of 2026, neither the reference to areas ideally above 1,000 m² is a statutory minimum nor the RU of up to 60% a general owner grant. The information sheet ties the 60% statement to large systems without self-consumption; outside the building zone, Art. 16a and 22 et seq. RPG and Art. 34 et seq. RPV apply. The municipality, Pronovo and grid operator must confirm the specific project before ordering.

| Metric | Value |
|---|---|
| Planning reference | The Fribourg information sheet refers ideally to areas above 1,000 m² |
| Car-park areas | Surfaces above or beside car parks with at least 15 spaces are considered zone-compliant under the sheet |
| Pronovo RU | Up to 60% of investment costs for large systems without self-consumption |
| Additional funding models | Tilt-angle bonus from 75° and floating market premium from 150 kW may apply |
| Electricity export | The reference market price for injected electricity is set quarterly |
Decision points
What determines the right path.
The zoning classification is the first decision. The Fribourg information sheet addresses undeveloped or partly open land in a building zone; areas above 1,000 m² are an ideal planning size, not a general statutory minimum. Outside the building zone, Art. 16a and 22 et seq. RPG and Art. 34 et seq. RPV apply, with a different procedure.
The use of the land changes the project logic. Under the Fribourg information sheet, surfaces above or beside car parks with at least 15 spaces are considered compliant with the zone; on slopes, the natural inclination must be reflected in the structure and access design. An open plot, a solar carport and a slope system are therefore not the same standard solution.
System type and orientation affect ground coverage and yield. The information sheet from the Fribourg Service de l’énergie distinguishes, among other options, one- or two-orientation tables, vertical bifacial modules, carports and slope-adapted systems. The choice determines whether farming between rows, vehicle use under the roof or stronger winter production remains possible.
The funding logic depends on the project model. For large systems without self-consumption, the Fribourg information sheet states that the one-time remuneration (RU) can cover up to 60% of investment costs; a tilt-angle bonus from 75° and a car-park bonus may also apply. These figures are not a blanket promise for every site and must be calculated through Pronovo.
The electricity-use model must be decided before sizing. The reference market price for injected electricity is set quarterly; self-consumption, an RCP, a battery, a PPA, a local electricity community or contracting create different load and revenue profiles. From 150 kW, a floating market premium may also be relevant as a model.
The municipality and specialist services determine site-specific feasibility. The site municipality is the first point for clarifying the simplified procedure; a formal permit file is handled through FRIAC in the Canton of Fribourg. Depending on the site, SeCA, SFN, SEn, SPC or Grangeneuve may also be relevant; these services are represented in the Fribourg working group for ground-mounted PV.
Sequence
How the project stays cleanly managed.
- 1
Establish the plot and zonecompile the land register, zoning plan, ownership and current use. Describe car parks, slopes and open building-zone land separately; the information sheet’s reference to areas ideally above 1,000 m² is a planning guide, not an automatic building permit.
- 2
Develop the system conceptselect table mounting, vertical bifacial modules, a solar carport or a slope-adapted structure based on area, orientation, ground coverage, agriculture, access and removal. For car parks from 15 spaces, document the zoning classification stated in the Fribourg information sheet.
- 3
Clarify the procedure with the site municipalitythe Fribourg information sheet describes a simplified procedure for ground-mounted PV in a building zone. Before ordering, the municipality must confirm which plans, elevations, site information and evidence apply to the specific plot; a formal application is entered through FRIAC.
- 4
Check technology and grid connection in parallelcombine the layout, inverter, cable route, transformer point, connection capacity, protection concept, access and removal plan. For self-consumption, an RCP, battery, PPA or local electricity community, align the load and metering concept with the responsible grid operator and, where needed, the Fribourg Service de l’énergie.
- 5
Calculate funding and revenuecheck the Pronovo RU, the tilt-angle bonus from 75°, the car-park bonus and, for systems from 150 kW, the floating market premium. According to the information sheet, the RU of up to 60% applies to large systems without self-consumption; the actual entitlement depends on the project model and Pronovo’s decision.
- 6
Synchronize the file, decision and executionbring the site plan, module and structural drawings, site and access information, grid documents, proof of ownership and the technical and economic option to the same project status. The formal application runs through FRIAC; only after the decision required by the municipality and procedure should ordering, installation, commissioning and Pronovo evidence be scheduled.
Checklist
Questions to settle before the quote.
- Classify building zones, car parks from 15 spaces and the planning guide of ideally more than 1,000 m²
- Compare table, vertical bifacial, carport and slope solutions by area and winter production
- Check the Pronovo RU of up to 60%, tilt-angle and car-park bonuses, and the floating market premium from 150 kW
- Coordinate the site municipality, FRIAC, grid operator and relevant specialist services before work starts
