PV mounting in Graubünden: assess the roof, access and notification
For PV mounting in Graubünden, we assess the actual building: roof construction, fixings, shading and access for materials and scaffolding. The quote separates roof work, electrical coordination and any additional assessments.
Clarify before quoting
A valley property and an exposed mountain building need different planning assumptions. Yield and mounting costs therefore depend on the roof and its surroundings. An alpine utility-scale plant is not a benchmark for every residential roof.
Prefer to contact us directly? Send your property address, annual electricity consumption (if known) and preferred timing. Roof photos or existing plans help with the initial assessment.

Context
How this service works in Graubünden in practice.
These answers help you plan the work and compare quotes on the same basis.
Planning & delivery
When should the municipality be involved?
The municipal building authority assesses whether a rooftop system is sufficiently adapted and permit-exempt. Graubünden’s planning ordinance allows 15 working days from notification to communicate any permit requirement. This is not a guaranteed project approval in every case.
- Before ordering, establish whether the location or building requires additional assessments.
- Document the proposed panel arrangement with its position, dimensions and building views.
- Keep the building procedure and technical connection assessment as separate tasks in the schedule.

Planning & delivery
Which roof conditions affect mounting?
The key questions are whether the existing roof can accommodate the system and how it will be fixed. A reliable design states its assumptions and identifies any structural or roofing assessments still needed.
- Roof condition: discuss remaining service life and possible renovation before covering the roof area.
- Fixings: have wind and snow loads assessed for the property; do not select a mounting structure solely by canton.
- Access: include scaffolding, material handling and safe future maintenance in the mounting scope.
Planning & delivery
What should be documented after mounting?
Roof mounting and electrical commissioning are different stages. The quote should identify who coordinates the interfaces and which documents you receive.
- Check that the panel layout and component records match the installed system.
- Document roof penetrations and cable routes, including responsibilities for waterproofing and electrical work.
- Check connection terms and remuneration with the actual grid operator. Repower tariffs do not automatically apply to every building in Graubünden.
