Solar panel installation in French-speaking Switzerland

The price depends on the size of the installation, the type of roof, the complexity of the installation and the equipment chosen. For a single-family home, the gross investment usually falls within a broad range that we specify in our free study, after examining your roof. The federal, cantonal and municipal subsidies then reduce this net investment.

Every residential photovoltaic installation in Switzerland benefits from the federal Pronovo subsidy. Depending on your canton and municipality, additional support may be added. The amounts vary depending on the power of the installation, the type of project and the canton. Our study prices the three layers of support applicable to your case.

The number depends on your annual consumption, the usable surface area of your roof, its orientation and your self-consumption objective. A typical single-family home in French-speaking Switzerland is equipped with an installation of between 6 and 12 kWp. The precise sizing is part of the free study.

The physical on-site installation generally takes 1 to 3 days for a single-family home. The administrative procedures (permits, subsidy application, grid connection) can add a few additional weeks — Abelarti manages the entire process.

Profitability depends on your consumption profile, your distributor's electricity tariff, the available subsidies and whether or not there is a battery. With the continued rise in residential tariffs and the current subsidies, the payback period usually falls between 7 and 15 years for a single-family home in French-speaking Switzerland.

Yes. Without a battery, self-consumption generally sits between 30 and 40%. With a properly sized battery, it often exceeds 60 to 80%, which reduces your dependence on the grid and stabilises your electricity cost. The relevance of a battery depends on your consumption profile — we assess it in the study.

Yes. The panels produce with any light, including diffuse light or in overcast weather. Winter production is lower than in summer, but remains significant. Snow slides off tilted panels, and the modules withstand heavy loads (up to 5,400 Pa for the modules we install).

Yes. We manage all the municipal permits, the federal Pronovo subsidy application, any cantonal and municipal applications, and the connection with your electricity distributor. You sign, we handle the paperwork.

The panels we install offer up to 30 years of product warranty and power warranty, with controlled degradation. In practice, the installation continues to produce beyond that, with a gradually declining yield — modern panels remain largely productive after 30 years.

Yes. Any unconsumed surplus is automatically fed back into the grid and remunerated at your distributor's feed-in tariff. The tariffs vary among distributors in French-speaking Switzerland. This remuneration is added to the savings on your electricity bill.

For most single-family homes in French-speaking Switzerland, the installation is subject to a simple notification to the municipality rather than a full building permit. The rules vary depending on the canton, the municipality and the nature of the building (protected zone, historic monument, etc.). Abelarti checks the framework applicable to your address.

In everyday language, “solar panel” often refers to photovoltaic panels (which produce electricity). There are also solar thermal panels, which produce heat for domestic hot water or heating. On this page, we are referring to photovoltaic panels — the ones that generate your home's electricity.
