PV Installation Graubünden – Roof & Electrical

People looking for PV installation in Canton Graubünden compare more than modules. They compare execution quality, roof protection and coordination. Exactly these points decide on a clean result before quoting and installation.

Local system fit

Graubünden is the canton with Switzerland's greatest alpine solar potential. Thanks to altitude and cold, PV systems here deliver 30–50% higher yields than in the midlands. Repower compensates from 6 Rp./kWh + HKN bonus. The Muttsee dam wall (2,500 m) with 5,000 panels delivers 3.3 million kWh/year – with three times higher winter production than comparable lowland systems. Alpine installation requires specialised mounting structures for extreme wind and snow loads.

For Graubünden we plan PV installations object-specifically: mounting structures per SIA 261, SUVA-compliant fall protection and complete handover documentation before the system goes live.

Graubünden comes with its own framework conditions – from incentives and tax treatment to technical requirements. From those, a cleanly managed project flow for your property takes shape.

01Service focus

What really matters for installation on site

People looking for PV installation in Canton Graubünden compare more than modules. They compare execution quality, roof protection and coordination. Exactly these points decide on a clean result before quoting and installation. Mounting structure per SIA 261, documented penetrations, SUVA-compliant fall protection and complete handover including string diagram, measurement protocol and photo documentation.

  • Mounting structure matched to tile, sheet metal, facade or flat-roof systems – not generic, but dimensioned object-specifically to wind zone (SIA 261), snow loads and building height.
  • Clean cable routing with documented penetrations and roof membrane protection. Every transition between roof and electrical installation is photographed and recorded.
  • Coordination of scaffolding, fall protection (SUVA-compliant), installation logistics and object-specific safety requirements – including a mounting concept prior to material ordering.
  • Photo documentation and traceable handover: single-line diagram, string plan, data sheets, measurement protocol, photos – everything needed for acceptance, grid operator and future service.

Why this canton shifts the priorities

Graubünden is the canton with Switzerland's greatest alpine solar potential. Thanks to altitude and cold, PV systems here deliver 30–50% higher yields than in the midlands. Repower compensates from 6 Rp./kWh + HKN bonus. The Muttsee dam wall (2,500 m) with 5,000 panels delivers 3.3 million kWh/year – with three times higher winter production than comparable lowland systems. Alpine installation requires specialised mounting structures for extreme wind and snow loads. Graubünden: pioneer of high-alpine solar systems. Nalpsolar (10 MW, 13 GWh/year at 2,000m), Scharinas (18.3 MW, 29 GWh/year, 13 GWh winter!). CHF 600/kWp facade subsidy = highest in Switzerland. Davos & St. Moritz: premium clientele + alpine peak conditions.

  • In Canton Graubünden, roof type, access and cable routing need to be clarified early so installation does not turn into change orders.
  • Owners compare execution quality, roof protection and clear ownership more than simple price promises.
  • Site logic directly affects timing, appearance and future maintenance.
03Project logic

How roof, installation and electrical work fit together

Graubünden grants tax breaks for PV construction – the entire costs are deductible as energy-saving investment. The deduction can be spread over several tax periods, which is particularly advantageous for larger alpine systems. Mounting structure and scaffolding planned around roof type and access.

  • Mounting structure and scaffolding planned around roof type and access.
  • Clean penetrations, orderly cable routing and documented handover.
  • Aligned workflow between installation, electrical work and commissioning.

Regional context

PV Installation in Graubünden: what matters here

In Canton Graubünden, cantonal rules, the responsible grid operator and local permit procedures shape how a project is planned and delivered. The points below show what really matters before quoting, installation and handover.

Regional starting point

In Canton Graubünden, incentives, grid operators and permit procedures change the priorities for this service.

Service core

Installation quality is decided before site work starts: roof access, mounting structure, cable routing and fall protection need to be planned together.

Grid & registration

For Canton Graubünden, grid operators such as Repower, metering concept and commissioning are aligned early.

Decision reason

In Canton Graubünden, roof type, access and cable routing need to be clarified early so installation does not turn into change orders.

Execution

Mounting structure and scaffolding planned around roof type and access.

Economic frame

Feed-in tariff and self-consumption are matched to the property; in the canton, ab 6 Rp./kWh + HKN-Bonus (Repower) is one relevant reference point.

Cantonal framework

Which cantonal framework shapes the project in Graubünden.

The technical service stays the same, but the project frame changes with the canton. That is exactly where incentives, tax treatment and MuKEn requirements become strategically relevant.

Local context

Graubünden sets the economic pace for this service.

Thanks to altitude and cold, PV systems in Graubünden often deliver 30–50% higher yields than in the midlands. Projects like the alpine solar system on the Muttsee dam wall (Glarus/Graubünden) demonstrate the enormous winter electricity potential of the Alps.

Tax and subsidy logic

Graubünden grants tax breaks for PV construction – the entire costs are deductible as energy-saving investment. The deduction can be spread over several tax periods, which is particularly advantageous for larger alpine systems. CHF 600/kWp facade subsidy (doubled in Green Deal). Highest facade subsidy in Switzerland! Solarexpress: accelerated permit procedure for large systems since 2022. Repower: min. 6 Rp./kWh + HKN bonus (0.5 Rp. winter, 0.2 Rp. summer).

Permits and energy law

Solarexpress: accelerated permit procedure for large systems since 2022. Three projects in Surselva area approved 2024 (Nalpsolar, Scharinas, others). Alpine special rules for 2,000m+ systems. Tourism hotspots (Davos, St. Moritz): special procedure. Graubünden considers the specific conditions of high altitude in its energy law. New buildings have self-generation requirements, taking into account the extreme climatic conditions in mountain municipalities.

Market signal and location

Graubünden: pioneer of high-alpine solar systems. Nalpsolar (10 MW, 13 GWh/year at 2,000m), Scharinas (18.3 MW, 29 GWh/year, 13 GWh winter!). CHF 600/kWp facade subsidy = highest in Switzerland. Davos & St. Moritz: premium clientele + alpine peak conditions. Alpine solar systems above 1,200 m receive partial special subsidies. Besides the Pronovo one-time payment, the Canton of Graubünden offers contributions through the Building Programme. Large projects like alpine solar parks benefit from simplified federal approval procedures.
