Solar panels in the canton of Vaud

For residential photovoltaics, the main support is the federal Pronovo One-Time Remuneration (CHF 350 – 700 / kWp), guaranteed for any compliant installation — universal across Switzerland. The canton of Vaud does not pay a dedicated cantonal subsidy for residential photovoltaics. The main subsidy is the federal Pronovo One-Time Remuneration, guaranteed and not subject to a cantonal budget. Some Vaud municipalities (notably Lausanne via équiwatt) offer an additional flat-rate bonus — we check your municipality before the quote. The canton of Vaud also applies the 100 Million Programme + Vaud Buildings Programme programme, which covers Heat pumps, insulation, windows, solar thermal — not photovoltaics. The full breakdown (eligibility, deadlines, worked examples) is on our Vaud subsidies guide.

Abelarti operates in every municipality in the canton. Our main service areas include Lausanne, Yverdon-les-Bains, Montreux, Renens, Nyon, Vevey, Pully. For other municipalities in the canton, enter your postcode in the form and an advisor will call you back to confirm the area.

The main distributor is Romande Energie (Main distributor across most of the canton). The indicative 2026 buyback rate is around CHF 0,07 – 0,10 / kWh. The exact rate depends on your municipality and your contract — Abelarti handles the entire grid connection and confirms the applicable rate during the study.

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

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

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

Profitability depends on your consumption profile, the electricity rate of your distributor (Romande Energie), the available subsidies and whether or not a battery is present. With an average irradiation of ~1 100 kWh/m²/an and current subsidies, the payback period most often falls between 7 and 15 years for a single-family home.

Yes. Without a battery, self-consumption is generally 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.

Yes. Panels produce in any light, including diffuse light or in overcast weather. Winter output is lower than in summer but remains significant. Snow slides off tilted panels and the modules withstand heavy loads.

Yes. We manage all municipal permits, the federal Pronovo subsidy application, the Vaud cantonal and municipal requests, and the connection with Romande Energie. You sign, we fill in the paperwork.

The panels we install offer up to 30 years of product warranty and power warranty. In practice, the installation keeps producing beyond that, with gradually declining output.

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