Solar Installation Thurgau – Planning to Commissioning

In Canton Thurgau, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. This page is built for that intent.

Local system fit

In Thurgau, a feed-in limitation to 70% of installed panel capacity applies from 2026 for new systems – making self-consumption optimisation and storage an integral part of every project plan. Thurplus develops innovative virtual ZEV and LEG models with "EigenverbrauchMax" and "LokalenergiePlus". The Solarstrom-Pool Thurgau provides additional subsidies for steeply mounted winter-electricity systems.

For a solar installation in Thurgau, 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 initial assessment to handover.

Service focus

What the full installation secures on site

In Canton Thurgau, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. This page is built for that intent. From initial assessment and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

Service focus

  • Initial assessment and 3D drone survey: 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.

Why this canton shifts the priorities

In Thurgau, a feed-in limitation to 70% of installed panel capacity applies from 2026 for new systems – making self-consumption optimisation and storage an integral part of every project plan. Thurplus develops innovative virtual ZEV and LEG models with "EigenverbrauchMax" and "LokalenergiePlus". The Solarstrom-Pool Thurgau provides additional subsidies for steeply mounted winter-electricity systems. 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.

Regional framework

  • In Canton Thurgau, 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 Canton of Thurgau allows full tax deduction for PV investments as property maintenance. Deductions can be spread over two consecutive tax periods if needed. Pre-check for roof, shading, electrical setup and potential constraints.

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 (max CHF 10,000). Roof systems: no more cantonal subsidy. Swiss first! 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. Thurgau uses proceeds from the CO2 fund for subsidies for energy renovations and PV systems. The Pronovo one-time payment is supplemented by cantonal contributions. EKT (cantonal electricity utility) also offers feed-in tariffs.
