Flat-roof solar in Innerrhoden: assess the roof before counting panels
A layout shows how many panels fit on your flat roof. A reliable order also needs clarity about roof condition, loads and future access. Vigorek discusses these points with you before the system option is selected.
Clarify before quoting
In Appenzell Innerrhoden, check protection status early. The cantonal solar page links to a permit-requirement map and the combined application and notification form. Review the actual plot and visible panel arrangement with the responsible building authority.
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 Appenzell Innerrhoden in practice.
These answers help you plan the work and compare quotes on the same basis.
Planning & delivery
Is the roof ready, or does it need renovation first?
The joint guide from Swissolar and building-envelope associations recommends a documented condition assessment and clarification of structural reserves for existing roofs. Wind, snow and ballast require property-specific assessment. A canton-wide weight allowance is no design basis.
- Roof records missing: first establish roof construction and load capacity; the maximum panel count remains a design option until then.
- Waterproofing needs renovation: request a coordinated roofing and PV quote, including junctions and cable penetrations.
- Green roof: plan vegetation maintenance and panel height together. Swissolar highlights possible shading from plants and the maintenance involved.
Planning & delivery
What determines notification or a permit application in Innerrhoden?
Cantonal guidance distinguishes sufficiently adapted rooftop systems in building and agricultural zones from cases requiring a permit. Protected properties and protection zones are explicitly listed as requiring permission. A flat roof alone therefore does not establish an exemption.
- Have the plot, building and proposed mounting arrangement assessed together; use the map to prepare that assessment.
- Prepare a roof plan and views for submission that clearly show panel fields, mounting height and their position relative to the roof edge.
- Schedule the building procedure and technical grid connection separately. Notification does not replace coordination with the responsible grid operator.

Planning & delivery
What should the flat-roof quote include?
Use this checklist when discussing the quote. Record who handles each item, what they deliver and whether the price includes it. This also identifies roof work that a panel-only price leaves out.
- Loads and fixings: identify property-specific design, ballast distribution and any structural assessment as explicit deliverables.
- Waterproofing: agree on the protective layer, material compatibility and treatment of existing roof junctions with the roofing specialist.
- Drainage: mark outlets and emergency overflows on the layout; check their accessibility during the joint roof inspection.
- Layout: record parapets, rooflights, vents and maintenance routes. Compare options using the same consumption and shading assumptions.
- Handover: record the as-built roof and cable plan, agreed inspection documents and responsibility for roof checks and system maintenance.
Planning basis
From initial guidance to a binding quote
This page explains our planning approach and links to the responsible bodies. Authorities and the grid operator decide on permits and connection. We define the binding scope in your quote after assessing the property.
