Service focus

What the full installation secures on site

In Canton Appenzell Ausserrhoden, 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 Canton Appenzell Ausserrhoden, the cantonal supplementary subsidy was reduced from 100% to 50% of federal subsidies in February 2025 – impacting project planning timelines. SAK offers straightforward grid connection in the region. The architectural sensitivity of Appenzell requires project management that plans for in-roof integration and heritage requirements from the start. Appenzell AR remains one of the most attractive cantons for PV thanks to the +50% cantonal top-up on the federal subsidy. The 345.6 kWp folded-roof project in Herisau shows local practice. The 2023 guideline makes it clear that traditional Appenzell buildings can also integrate solar cleanly. Since 2026, LEG models provide additional commercialization options.

Regional framework

  • In Canton Appenzell Ausserrhoden, 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.
