Short answer
What you need to know first.
Helps owners in Canton St. Gallen connect the current Pronovo framework for PV with the local project workflow, from funding category and grid process to consistent documentation.
Important
Pronovo is the primary source for funding categories, the application route, the guideline and current detailed questions on the one-time payment. For concrete projects in Canton St. Gallen, current steps, special cases and changes to the installation should therefore be checked directly via Pronovo’s current EIV page, FAQ and application route. Local grid processes remain a separate matter and must be coordinated independently with the responsible grid operator.
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.
For the large majority of residential projects, KLEIV is the likely category because it applies to systems below 100 kW. Anyone planning larger commercial or multi-family projects should check early whether GREIV becomes relevant instead.
According to Pronovo, HEIV is intended for systems without self-consumption in the range from 2 kW to 149.99 kW. This distinction directly affects the project logic and should therefore not be mixed up with the typical KLEIV or GREIV cases.
The funding process and the grid process are not identical. In Canton St. Gallen, Pronovo-related topics and the technical coordination with the responsible grid operator run in parallel, which is why documents, responsibilities and timing should be coordinated early.
What remains decisive is the consistency of project data. Funding category, capacity figure, system type and location details should remain consistent across the quote, the grid process and the Pronovo documentation to avoid queries.
Current detailed steps and special cases should always be checked directly with Pronovo. Questions about changes to the system, bonuses or submission steps in particular are better grounded in the current FAQ and guidelines than in generalized secondary sources.
Sequence
How the project stays cleanly managed.
- 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
In parallel, clarify the responsible grid operatordepending on location in Canton St. Gallen, the local grid operator or, in the city of St. Gallen, SGSW becomes relevant. Grid-operator topics such as registration, metering concept and technical approvals should be considered early.
- 3
Capture the technical project data consistentlycapacity, system type, self-consumption logic and location details should be documented so that they align across the quote, the grid process and the Pronovo documentation.
- 4
Check the current Pronovo materials before filingthe current EIV page, the FAQ, the application route and the guideline define the authoritative current status. The current Pronovo material should be used especially for special cases and changes to the installation.
- 5
Deliberately connect the grid and funding processesthe funding logic, grid-operator coordination and commissioning documentation should not be treated as separate worlds. The better these steps are aligned, the lower the risk of follow-up questions.
Checklist
Questions to settle before the quote.
- The sequence matters: why Pronovo registration must happen before commissioning, and what applies if registration was missed
- Two separate registrations: Pronovo EIV and grid operator registration with SGSW as parallel processes in Canton St. Gallen
- Installation notification and ESTI obligation: which documentation tasks fall to the licensed electrical installer
