Solar Installation Graubünden – Planning to Commissioning
In Canton Graubünden, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. That is exactly how we run solar projects – from the pre-check to documented commissioning.
Clarify before quoting
In Canton Graubünden, alpine PV systems deliver up to 50% of annual production in winter – strategically decisive for Swiss supply security. The federal government subsidises large alpine systems with up to 60% of investment costs (for winter yield ≥500 kWh/kW/year). Repower coordinates grid connection and permits regionally. Projects like Nalpsolar (10 MW) and the Axpo expansion in Ilanz (30–50 MW) demonstrate scalability.
For a solar installation in Graubünden, success depends not only on module area but on the process: 3D survey, transparent quote, grid-operator coordination and commissioning with full documentation. Vigorek handles the full coordination — from the initial estimate to handover.

Context
How this service works in Graubünden in practice.
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.
Service focus
What the full installation secures on site
Vigorek plans and delivers complete PV systems across all German-speaking cantons: solar modules, inverter, roof installation, electrical coordination and commissioning. Battery storage and a wallbox can be planned around your consumption. Your quote defines the scope and responsibilities.
- Initial estimate and 3D survey (drone): roof, orientation, shading, electrical setup and possible constraints — before any quote is prepared.
- Transparent quote with clearly separated line items: material, installation, scaffolding, electrical, registration, commissioning — each one individually listed.
- Coordination of Pronovo registration, metering concept, grid-operator queries and meter replacement through to full commissioning.
- Optional integration of battery storage, wallbox and energy management — only where the usage profile and expansion goals support it.
Regional framework
Why this canton shifts the priorities
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, a pre-check saves time when permits, metering or electrical setup are not standard.
- Owners want traceable quotes instead of aggressive package promises.
- A documented commissioning reduces later questions and service overhead.
Project logic
How coordination makes the difference
The order records these steps, responsibilities and required documents. Outstanding assessments belong in the schedule before work begins.
- Pre-check for roof, shading, electrical setup and potential constraints.
- Coordination of registration, metering concept and commissioning.
- Clean handover with traceable documentation for operations and service.
Regional context
Solar system 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
- A complete solar installation depends on sequencing, grid-operator coordination, electrical planning and clean commissioning.
- Grid & registration
- For Canton Graubünden, grid operators such as Repower, metering concept and commissioning are aligned early.
- Decision reason
- In Canton Graubünden, a pre-check saves time when permits, metering or electrical setup are not standard.
- Execution
- Pre-check for roof, shading, electrical setup and potential constraints.
- 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.
