In Canton Vaud, understanding a solar project is not just about finding an amount. The cantonal layer, the federal Pronovo layer and the project layer must be separated first. That ordering is what prevents weak sales promises and keeps the local intent clean.
What is the short answer for Vaud?
For a Vaud photovoltaic project, the correct reading starts with the local source, then moves to the federal Pronovo logic and only after that to the concrete project. The useful answer is therefore not a fixed amount, but a verification sequence: local framework, possible stacking, timing and file logic.
The canton page should first clarify who decides what. The canton provides the local entry point, but it does not replace either the solar project page or Pronovo itself.
In practice, Vaud mainly helps determine whether the case should be read only through Pronovo, whether an additional local layer exists, or whether the real issue sits with a utility, a municipality or the order of actions.

Who decides what between canton, Pronovo and the solar project?
The canton and Pronovo do not play the same role. Vaud provides the local reading and context. Pronovo covers the federal layer. The solar photovoltaic project page remains the best place for installation logic, self-consumption, documents and the overall technical reading.
This split prevents duplication. The canton page should not rebuild the Pronovo page or the solar project page. Its job is to show where the reader should move next based on the actual question.
If the need is about the one-time remuneration, filing order or Pronovo documents, the next step is Pronovo. If the need is about project structure, self-consumption or technical setup, the next step is the solar project page.
| Layer | Role | Key verification |
|---|---|---|
| Canton Vaud | Qualify the local framework | competent authority, local source, separate stacking check |
| Pronovo | Read the federal layer | one-time remuneration, filing logic, scheme-specific documents |
| Solar project page | Read the concrete case | project structure, self-consumption, timing and technical documents |
How should possible stacking be read without promising automatic stacking?
The word stacking is only useful when handled carefully. A Vaud solar project may touch several subsidy or advantage layers, but that never means everything stacks automatically, in any order, or without a separate local verification.
The clean approach is to treat the local layer as its own check. It must be confirmed whether the local measure is really open to the relevant case, whether it follows its own timing and whether it asks for proofs outside the Pronovo file.
That is why the canton page should stay sober. It prepares the local check, but should not promise broad compatibility or invent a single rule for every owner and every installation.
Which order matters before a signed quote, an order or the works?
For a Vaud solar file, sequence matters as much as the subsidy itself. Before signing, ordering or starting works, the local layer, the Pronovo logic and the documentary path should already be qualified. Good order reduces blockage risk more reliably than a simple amount question.
The first filter separates project logic, federal logic and local logic. Only after that does it make sense to look at documents, work calendar and final proofs.
The canton page therefore does not replace a procedure page. It only prepares the next step: which cluster node should be read next to avoid an inconsistent filing path or promises made too early.
When should the Vaud page be left for another node?
The Vaud page should be left once the question becomes technical, federal or procedural. The canton page is built to orient the reader, not to absorb the whole file. Moving toward Pronovo, the solar project page or a procedure page is part of the intended cluster design.
If the question is about federal eligibility, PRU/GRU/RUE or portal documents, the answer belongs on the Pronovo side. If it is about the real installation, the photovoltaic project page becomes the better reading layer.
The canton page therefore remains a local hub, not a catch-all article. That distinct role is exactly what protects the hierarchy between Vaud, Pronovo and photovoltaic.

Frequently asked questions
Is the Vaud page enough for a full solar project?+
No. It works as a local hub and then routes toward Pronovo or the solar project page.
Can stacking be promised from the canton page?+
No. The canton page should prepare a separate local check and should not claim general stacking.
When should the reader move to Pronovo?+
As soon as the question becomes federal: one-time remuneration, filing order, technical categories or specific documents.
