Combine Pronovo and confirmed local aid: the essential rules

Editorial responsibility: Franck Tournier · Report a fix

TL;DR

The Pronovo Unique Reward is the reliable basis. Cantonal or municipal aid can only be added if the program exists for your address, your type of project and your schedule. Only include it in the budget after official confirmation.

1) The basis: the Unique Retribution

RU Pronovo constitutes the federal base of support for photovoltaics. Its amount depends on the installed power and type of installation. It is independent of local programs.

2) The local complement confirmed

Some municipalities, certain distributors and some cantonal programs offer aid additional, but they do not automatically cover residential photovoltaics. The mechanisms vary: fixed amount, battery bonus, energy renovation, insulated roof or specific project.

3) The accumulation limit

The accumulation is not unlimited. The authorities apply a principle of proportionality to avoid overfinancing the project. Before signing the quote, always check the ceilings, the exact timetable and conditions from the authority actually funding the aid.

Frequently asked questions

Is a municipal bonus taxable?+

It must be declared. According to tax rules, it generally reduces the basis of deductible energy expenses. In practice, we always think in real net cost after subsidies.

Does Pronovo also manage my cantonal or municipal aid?+

No. Pronovo manages the federal part. Cantonal, municipal, battery or renovation files follow their own procedures, timetables and supporting documents.

What order should I follow to avoid errors?+

Separate Pronovo from other aids. For a small PV installation, Pronovo is finalized after commissioning; local assistance, battery or renovation may require an application before work. Archive all written confirmations.
