Between the EIV application and the payout, several months typically pass – depending on Pronovo's application volume, sometimes longer. Important for context: the wait is a payout issue, not an entitlement issue – the money comes, just not immediately. You have the biggest influence yourself through the quality of your dossier: complete applications go through, incomplete ones trigger follow-up queries and lose months. (As of: July 2026)
Key points in brief
- Expect several months between application and payout – and plan your financing so you don't depend on it.
- The entitlement is unaffected by the waiting time: the rates at the time of commissioning are decisive.
- The most common avoidable time loss: incomplete or faulty certification documents.
- Pronovo periodically publishes forecasts on the processing situation – the most honest timeframe available.
- For large systems (GREIV), the application can be submitted before construction – a different waiting model.
Why does the payout take so long in the first place?
Because behind the one-off feed-in incentive stands a mass process with a review requirement. Pronovo is the central processing body for the Confederation's funding programmes – every application from all over Switzerland lands there, and every one is reviewed: system data, certification, category, rates. The solar boom of recent years simply means a great many dossiers.
There's also the payout system: applications are processed in order, and the available funding flows in tranches. So the wait isn't a sign that something's wrong with your application – it's the normal state of a well-filled funding pot with an orderly process.
For your own planning, one distinction is central, covered in detail in the EIV guide: entitlement and payout are two different things. The entitlement arises with a system built to the rules and a cleanly submitted application; the rates at your commissioning date are decisive. The payout follows later – but it follows.
What timeframe should I concretely expect?
The honest answer has two parts – an order of magnitude, and a source for the current state.
The order of magnitude: several months between a complete application and payout, longer still in phases with a high application volume. Anyone factoring the EIV into their construction financing should treat it as a later inflow, not as funds for the installer's final invoice.
The source: Pronovo periodically publishes forecasts on its website about the processing situation – for example, by when completely submitted applications are expected to receive a funding approval and payout. That's the most reliable timeframe available, because it reflects the current dossier situation. Any flat number of weeks from a consultation, by contrast, should be treated with caution – the situation shifts with the application volume.
The process itself has four stations, and each can cost time:
| Stage | What happens | Your influence |
|---|---|---|
| Submit application | Dossier in the Pronovo portal | Completeness! |
| Certification | Auditor/grid operator confirms the system data | correct documents |
| Review & ruling | Pronovo reviews, issues the funding approval | none (queue) |
| Payout | Transfer to the stated account | Correct account details |
Orientation, as of: July 2026. Pronovo's current publications are decisive.
The click-through of the portal is shown in the article on Pronovo registration; for large systems a different time model applies – the GREIV application can be submitted before construction, so the wait runs alongside the construction phase instead of after it.
What speeds up my application – and what slows it down?
You have no influence over the queue at Pronovo. But you do over everything before it – and that's exactly where it's decided whether your dossier sails through or loses months.
The biggest brake: the incomplete dossier. Missing or faulty system data in the certification is the most common reason for follow-up queries – and every follow-up query means a loop: Pronovo writes, someone has to respond, the dossier re-enters the queue. An application that's complete the first time saves more time than any other lever.
The second brake: late submission. The KLEIV application can only be submitted after commissioning – but then it should move quickly. Anyone who lets the application sit for months extends the total wait by exactly those months, gaining nothing.
What you can do yourself:
1. Collect documents from day one – the commissioning report, system data and meter number belong in one folder, not three email inboxes. 2. Take certification seriously – confirmation by the auditor or grid operator is the most error-prone step; this is where follow-up queries arise. 3. Leave the application to the specialist company – the installer already has the technical data and knows the forms; with us, submission is part of the project scope. 4. Track the status in the portal instead of phoning – the Pronovo portal shows the dossier status; calls don't speed up the queue.
How do I plan financing around the waiting time?
With a simple rule: the EIV is a later inflow, not a means of payment. The installer's invoices fall due before the funding arrives – so the project's payment plan has to work without the EIV. How the EIV fits into the total cost is shown in the cost guide; it typically covers a range of 15 to 25 per cent of the investment – money that comes, just later.
Two side effects of the waiting time deserve attention. First, tax: the EIV belongs in the tax return – depending on the payout year, it can fall into a different tax year than the investment; how to handle that is shown in the article on the tax deduction. Second, psychology: the system produces from day one and lowers the electricity bill – the economic benefit doesn't wait for Pronovo, only the funding contribution does.
"Is the money secure?" is the most common question – and the answer remains: yes, provided the dossier is correct. Experience shows the waiting time makes customers nervous mainly when nobody has explained it beforehand. That's why it belongs in our first conversation: the EIV comes, but it comes months after commissioning – don't plan it in for the final invoice. And the second standard line: most of what slows applications down happens before Pronovo, not at Pronovo. Since we've been submitting every dossier with complete certification, follow-up queries have become the rare exception on our projects.
Frequently asked questions
Does my entitlement lapse if I wait a long time for the payout?
No – the wait affects only the payout, not the entitlement. The rates at your system's commissioning date are decisive; the queue changes nothing about that. What matters is only that the application is cleanly submitted and any follow-up queries are answered.
Can I speed up processing at Pronovo?
Not the queue itself – there's no express process. What you can speed up is your own share: a complete dossier, correct certification, prompt submission after commissioning, and quick answers to any follow-up queries. That's what makes the difference of months.
How do I know how long it currently takes?
Pronovo periodically publishes forecasts on its website about the processing and payout situation – that's the most reliable figure, because it reflects the current application volume. You can see your own dossier's status in the Pronovo portal.
Do I get interest for the waiting time?
No, the one-off feed-in incentive is paid out at the amount decided – no interest on the waiting period is provided for. That's another reason to treat the EIV in your financial planning as a later inflow, not as a short-term available fund.
Does the long wait also apply to cantonal and municipal funding?
That differs by programme – municipal contributions are sometimes paid out noticeably faster, but follow their own rules (often: application before construction starts!). Each programme's deadline logic is in its funding overview; don't assume all pots tick the same way.
