PV installation in Thurgau – cleanly planned and registered
Thurgau is Switzerland's largest fruit-growing region and sits on Lake Constance, where well-oriented barn, farm and commercial roofs offer ample surface for solar power. As early as Easter 2022 the canton produced more electricity than it consumed for the first time – with solar a central driver. We plan your PV system accordingly and handle coordination from roof structure to grid registration.
Clarify before quoting
In Thurgau the canton-owned EKT AG operates the medium-voltage distribution grid, while the end-customer connection sits with local utilities such as Thurplus in Frauenfeld or Arbon Energie depending on the municipality. What matters here: the correct registration with the responsible grid operator and a look at the cantonal solar map, which shows per roof whether a building permit is required or a notification to the municipality suffices. For the canton's energy subsidy programme we coordinate the performance and base contributions plus the federal one-time payment.
For Thurgau we plan PV installations object-specifically: mounting structures per SIA 261, SUVA-compliant fall protection and complete handover documentation before the system goes live.

Context
How this service works in Thurgau in practice.
Thurgau 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 really matters for installation on site
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.
Regional framework
Why this canton shifts the priorities
Thurgau: Swiss paradigm shift — first canton to subsidize ONLY facade systems (from April 2025). This signals the shift from roof to facade in the PV industry. Solar map immediately shows every owner their status. Solar power pool: 25 years of experience.
- Thurgau's cantonal energy subsidy programme supports PV systems from 2 to 100 kW and, from 2026, additionally funds battery storage for grid stabilisation; the application must be filed before construction.
- The cantonal solar map determines the route: systems under 35 m² in building zones need neither permit nor notification, otherwise a notification process with a 20-day deadline before construction applies.
- As a fruit-growing and Lake Constance region, Thurgau offers many large barn, farm and commercial roofs that are especially suited to high-yield PV systems with strong self-consumption.
Project logic
How roof, installation and electrical work fit together
The order records these steps, responsibilities and required documents. Outstanding assessments belong in the schedule before work begins.
- Grid connection and metering: registration and coordination with the responsible distribution grid operator, such as Thurplus in Frauenfeld or Arbon Energie, within the cantonal EKT grid.
- Permit clarification via the cantonal solar map and, where required, running the notification process with the municipality observing the 20-day deadline before construction.
- Subsidies set up cleanly: documentation for the cantonal energy programme and registration of the one-time payment with Pronovo.
Regional context
PV Installation in Thurgau: what matters here
In Canton Thurgau, 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 Thurgau, 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 Thurgau, grid operators such as Thurplus, metering concept and commissioning are aligned early.
- Decision reason
- Thurgau's cantonal energy subsidy programme supports PV systems from 2 to 100 kW and, from 2026, additionally funds battery storage for grid stabilisation; the application must be filed before construction.
- Execution
- Grid connection and metering: registration and coordination with the responsible distribution grid operator, such as Thurplus in Frauenfeld or Arbon Energie, within the cantonal EKT grid.
- Economic frame
- Feed-in tariff and self-consumption are matched to the property; in the canton, Marktpreis BFE (quartalsweise) + 6 Rp./kWh Min. bis 30 kW + 2 Rp. HKN (Thurplus, ab 2026) is one relevant reference point.
Cantonal framework
Which cantonal framework shapes the project in Thurgau.
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
Thurgau sets the economic pace for this service.
The "Mostindien" canton offers plenty of roof space on agricultural buildings and fruit storage halls – ideal for large PV systems. The Lake Constance region also benefits from a mild climate and above-average sunshine hours.
Tax and subsidy logic
The Canton of Thurgau allows full tax deduction for PV investments as property maintenance. Deductions can be spread over two consecutive tax periods if needed. Facade-exclusive from April 2025: CHF 200/kWp subsidy ONLY for facade systems pitched ≥75° (max CHF 10,000 per system, annual budget CHF 100,000). Pure roof systems: no cantonal subsidy since 1 Apr 2025. Swiss first! New for 2026: cantonal battery storage subsidy of CHF 1,000 flat from 10 kWh usable capacity (max. 25%, application before installation). Solar power pool: 25 years of history, 800+ systems, 16 MW capacity.
Permits and energy law
Interactive solar map: for every building the map shows whether notification or building permit is needed (Green = notification, Orange = permit, Red ISOS = strict review). Facade systems: own rules. Roof systems: standard notification procedure. Thurgau implements energy regulations pragmatically and has adopted parts of MuKEn 2014 into its cantonal energy law. New buildings have self-generation requirements – PV systems are the preferred solution.
Market signal and location
Thurgau: Swiss paradigm shift — first canton to subsidize ONLY facade systems (from April 2025). This signals the shift from roof to facade in the PV industry. Solar map immediately shows every owner their status. Solar power pool: 25 years of experience. Since April 2025 the canton (Solarstrom-Pool) subsidises exclusively facade systems pitched ≥75° with CHF 200/kWp, max. CHF 10,000 per system and an annual budget of CHF 100,000. Pure roof systems no longer receive a cantonal subsidy – here the federal Pronovo one-time payment remains the key direct support. New stationary battery storage with at least 10 kWh of usable capacity receives a one-time cantonal investment grant of CHF 1,000 in 2026 (max. 25% of total investment, application before installation, capped at 700 applications). Thurplus pays for exported solar power from 2026 on a market basis (quarterly BFE reference market price) plus 2 Rp./kWh for guarantees of origin, with a statutory minimum of 6 Rp./kWh up to 30 kW.
