How it works
Each measure has its own funding
In Switzerland, energy grants for private individuals are structured by type of work: each measure benefits from its own support scheme. When properly coordinated, these contributions substantially reduce the net cost of your project — we quantify them precisely in your quote.
Photovoltaics — Pronovo one-off remuneration (federal level)
Any compliant photovoltaic installation in Switzerland qualifies for the one-off remuneration paid by Pronovo. Its amount is calculated with the official Pronovo rate calculator, from the power and configuration of the installation. The application must be submitted after the installation has been commissioned. Note that in French-speaking Switzerland, the canton of Geneva offers a supplement through its ECO21 programme (SIG). No other French-speaking canton grants a specific subsidy for residential photovoltaics based on a per-kWp amount.
Heat pump, insulation, windows — Buildings Programme (cantonal level)
The cantons mainly intervene through the Buildings Programme, which supports in particular the replacement of heating systems with a heat pump, thermal insulation work, replacing windows or even solar thermal. The amounts vary depending on the canton and the nature of the work (from CHF 3'500 — Jura, air-to-water — to CHF 20'000 — Vaud, ground-source — for a heat pump, and from CHF 40 to 140 per m² for insulation depending on the canton; exact scales are on our canton guides). As the grants are subject to annual budgets, it is advisable to submit applications early in the year. The application must be approved before work begins.
Storage battery — Special case
Storage batteries are generally not the subject of specific subsidies in the French-speaking cantons. The canton of Neuchâtel is an exception — one of the few Swiss cantons supporting residential batteries (CHF 800 + CHF 80/kWh from March 2026, application filed after commissioning). In Geneva, the utility SIG pays a battery premium of CHF 130/kWh. Elsewhere, the grants concern only the overall photovoltaic installation, via Pronovo, without explicitly including the battery.
Municipal subsidies (local bonuses)
Some municipalities offer additional grants in the form of flat-rate amounts that vary widely by municipality (for example Lausanne as well as several Geneva municipalities, Yverdon or La Chaux-de-Fonds). These contributions can often be combined with federal and cantonal grants. A case-by-case check is nonetheless required depending on the municipality.
