In-roof solar in the Canton of UriCHF 400 per m² integrated

Solar roofs in historic core zones and protected townscapes

In the Canton of Uri, you notify sufficiently well-adapted solar systems on roofs and facades with the online form «Meldung einer Solaranlage» (notification of a solar system) to your commune’s building authority. Based on your answers, the form clarifies whether a building application is needed after all. Systems that are not sufficiently well adapted, and systems on cultural and natural monuments of cantonal or national importance, need a building permit. In townscape protection areas your commune’s rules apply, which we check in advance. For systems outside the building zone, further rules apply, which we clarify with the canton in advance. We did not find a separate cantonal in-roof rule in the documents.

Subsidies

For integrated systems, the federal government pays a higher one-off payment (Einmalvergütung, EIV) through Pronovo than for add-on systems. Uri also goes its own way. The Energie Uri 2026 subsidy programme pays CHF 60 per square metre for thermal insulation of the building envelope. For areas with integrated photovoltaics at a tilt of 60 to 90 degrees, it is CHF 400 per square metre. The canton defines integrated as the modules replacing the weather-protection layer. This applies to in-roof and facade systems. The requirements are a building permit for the building from before 2000, an application before construction starts, the U-value requirements and a plan showing the module area. Complete replacement of the roof in the same place is also eligible. Completely new building parts, extensions and additional storeys are not, as the subsidy targets existing buildings.

Plan the roof renovation and solar roof together

A tilt of 60 to 90 degrees mainly suits facades and very steep roofs. It also brings more winter electricity, which counts in the Uri valleys with the shadows of the mountain slopes. On flatter roofs, an in-roof system remains a question of appearance, roof build-up and cost. At the site visit we work out both routes and submit the application before construction starts.
