PV incentives in St. Gallen: Pronovo, city support and documents

For a PV system in Canton St. Gallen, federal funding, grid connection and possible support from the municipality where the property is located must be checked separately. Pronovo distinguishes KLEIV for systems below 100 kW, GREIV for systems from 100 kW and HEIV for systems from 2 kW to 149.99 kW without self-consumption. Timing matters for a typical new KLEIV system: the application can only be filed after the system has been realised. Pronovo lists, among other items, an acceptance protocol or alternatively a safety certificate plus measurement and test protocol, a land-register extract no more than one year old and payment details; integrated systems also require photos. In the City of St. Gallen, a municipal contribution may be available for PV systems up to 100 kWp subject to additional conditions. Outside the city, check any municipal support separately through the St. Gallen funding portal.

Short answer

When must I file the Pronovo application for a PV system in St. Gallen?

Helps owners in St. Gallen determine the funding category and filing time, prepare Pronovo documents and coordinate federal, grid and municipal processes in the right order.

Important

The EIV programme and filing time depend on the specific project. The statement about filing after realisation refers to a typical KLEIV application for a new system; GREIV, HEIV, auctions and extensions may follow different routes. Pronovo, the responsible grid operator and, where applicable, the city or municipality are authoritative for their respective process. Check municipal funding amounts and conditions against the current status before awarding the work.

Decision points

What determines the right path.

The Pronovo page clearly distinguishes between KLEIV, GREIV and HEIV. For owners in Canton St. Gallen, the key first step is therefore the correct funding category and not a blanket assumption that every PV installation follows the same funding path.

KLEIV is likely for a typical new residential system, but the filing time must not be confused with a preliminary notice: Pronovo only allows the KLEIV application once the system has been realised. GREIV, HEIV and any auction cases follow different routes depending on the project.

According to Pronovo, HEIV is intended for systems from 2 kW to 149.99 kW without self-consumption; for systems of 150 kW or more without self-consumption, Pronovo refers to auctions. This distinction affects the project logic and must not be mixed up with the usual KLEIV case.

The funding process and the grid process are not identical. In Canton St. Gallen, the grid route depends on the specific connection address; in the City of St. Gallen, sgsw is a central point of reference. Registration, metering and technical approvals should be prepared alongside the funding plan.

The documents can be prepared sensibly before installation. For a typical KLEIV application, Pronovo lists an acceptance protocol or alternatively a safety certificate plus measurement and test protocol, a land-register extract no more than one year old and payment details; integrated systems additionally require three photos.

Federal and municipal support must be calculated separately. The City of St. Gallen supports PV systems up to 100 kWp under its own conditions with a contribution of 50% of the KLEIV performance contribution; support in other municipalities is not automatic and must be checked in the St. Gallen funding portal.

Current detailed steps and special cases should always be checked directly with Pronovo. Questions about system changes, bonuses or filing steps in particular are better grounded in the current FAQ, application assistant and guideline than in generalized secondary sources.

Sequence

How the project stays cleanly managed.

  1. 1

    Start by determining the funding categoryaccording to Pronovo, KLEIV applies to systems below 100 kW, GREIV to systems from 100 kW, and HEIV to installations without self-consumption in the range from 2 kW to 149.99 kW. This classification belongs at the beginning of planning.

  2. 2

    Confirm the responsible grid operator using the connection address: in Canton St. Gallen, the canton name alone does not determine the grid route. In the City of St. Gallen, sgsw is central; elsewhere, the local requirements apply.

  3. 3

    Collect documents before installationrecord capacity, system type, self-consumption logic and location details consistently. For the later KLEIV application, plan the acceptance protocol or safety certificate plus measurement and test protocol, land-register extract, payment details and, for integrated systems, the three required photos.

  4. 4

    For a typical new KLEIV system, wait until the system is realised and then file the application in the Pronovo customer portal. A KLEIV application is not replaced by a registration before commissioning; for GREIV, HEIV or auctions, first check the appropriate Pronovo route.

  5. 5

    For the City of St. Gallen, check the additional contribution after the Pronovo filing or with the Pronovo document requested by the city. Outside the city, search for municipal support separately in the funding portal; do not treat federal, grid and municipal evidence as one application.

  6. 6

    Finally, cross-check every detailfunding category, capacity, system type, location, commissioning date and ownership should align across the quote, grid process and Pronovo documents. For special cases, the current EIV page, application route, FAQ and guideline remain authoritative.

Checklist

Questions to settle before the quote.

  • Sequence KLEIV correctly: why an application for a new system can only be filed after the system is realised
  • Separate federal, grid and municipal processes: Pronovo, the responsible grid operator and possible municipal support are distinct processes
  • Prepare the documents: acceptance protocol or safety certificate, measurement and test protocol, land-register extract, payment details and any required photos
