It is the first question most homeowners ask: how much does a photovoltaic installation really cost in Switzerland? The honest answer is that there is no single price — but there are clear price ranges, reliable benchmarks and concrete factors that drive the bill up or down. This guide gives you the real figures for the French-speaking Swiss market in 2026, with concrete examples by property size.
Price per kWp: the benchmark unit
In Switzerland, the cost of a solar installation is measured in francs per kilowatt-peak (kWp). The kWp is the theoretical output of the installation under optimal conditions. It is the unit that lets you compare quotes with one another, regardless of the size of the project.
In 2026, the price per kWp for a turnkey residential installation in French-speaking Switzerland generally falls within this range:
- Standard installation: CHF 1'800 to CHF 2'200 / kWp
- Premium installation (high-end equipment, meticulous integration): CHF 2'200 to CHF 2'800 / kWp
- Small installations (under 6 kWp): often above CHF 2'800 / kWp because of fixed costs
The larger the installation, the lower the price per kWp: fixed costs (scaffolding, travel, grid connection, administrative procedures) are spread over a greater output.
Indicative 2026 price table by system size
Turnkey ballpark figures, before subsidies, for an accessible tiled roof in French-speaking Switzerland. The “premium” column corresponds to high-end equipment (high-efficiency full-black panels, hybrid inverter, meticulous integration). The one-time remuneration is calculated at the 2026 rate for added installations (CHF 360 / kW).
| Power | Panels · area | Standard | Premium | Pronovo 2026 | Standard net after Pronovo |
|---|---|---|---|---|---|
| 5 kWp | ≈ 11 panels · 23 m² | CHF 13'000 – CHF 16'000 | CHF 15'600 – CHF 19'200 | CHF 1'800 | CHF 12'700 |
| 8 kWp | ≈ 18 panels · 38 m² | CHF 16'000 – CHF 20'800 | CHF 19'200 – CHF 24'960 | CHF 2'880 | CHF 15'520 |
| 10 kWp | ≈ 23 panels · 48 m² | CHF 18'000 – CHF 23'000 | CHF 21'600 – CHF 27'600 | CHF 3'600 | CHF 16'900 |
| 12 kWp | ≈ 27 panels · 57 m² | CHF 21'600 – CHF 27'600 | CHF 25'920 – CHF 33'120 | CHF 4'320 | CHF 20'280 |
| 15 kWp | ≈ 34 panels · 71 m² | CHF 21'750 – CHF 28'500 | CHF 26'100 – CHF 34'200 | CHF 5'400 | CHF 19'725 |
| 20 kWp | ≈ 45 panels · 94 m² | CHF 29'000 – CHF 38'000 | CHF 34'800 – CHF 45'600 | CHF 7'200 | CHF 26'300 |
Basis: panels of approximately 440 Wp, 2.1 m² each. The net figure does not take into account cantonal grants or the tax deduction, which reduce the bill further.
Worked examples by property size
Here are realistic ballpark figures for different types of property in French-speaking Switzerland, before subsidies, for a quality installation:
Standard family villa — 8 to 10 kWp
A typical residential roof usually accommodates 18 to 25 panels. Indicative budget: CHF 18'000 to CHF 26'000. This is the most common case for a detached house.
Large villa or large roof — 12 to 20 kWp
For a larger house, with a sizeable roof or several roof faces, allow CHF 28'000 to CHF 48'000. At this level, architectural integration and the choice of discreet equipment make a real aesthetic difference.
Installation with storage (battery)
Adding a home battery to store your production increases the budget by CHF 8'000 to CHF 20'000 depending on capacity. It improves self-consumption and autonomy, and is particularly worthwhile for properties with high consumption or equipped with charging stations.
What drives the price
Two quotes for the same output can differ considerably. Here are the decisive factors:
- The type of roof: an easily accessible roof with flat tiles costs less than a slate, complex or steeply pitched roof.
- The quality of the equipment: panels, inverters and mounting systems come in several ranges. Premium equipment offers better efficiency, a better warranty and better durability over time.
- Architectural integration: on a beautiful house, meticulous integration (full-black panels, flush mounting) comes at a cost but preserves the look of the building.
- The complexity of the electrical connection: distance to the distribution board, any upgrade required, surge protection in accordance with the NIN (Swiss low-voltage installation standard).
- Administrative procedures: some companies charge separately for handling permits and subsidies. At Amperwatt, this support is included.
The real cost after subsidies
The advertised price is never the final price. In Switzerland, several forms of support significantly reduce the bill:
- The Pronovo one-time remuneration: CHF 360 per kWp for an added installation and CHF 400 per kWp for an integrated installation (2026 rates, under 30 kW), i.e. CHF 3'600 for a 10 kWp on-roof installation.
- The SIG solar bonus: in Geneva, an additional 25% of the Pronovo amount for self-consumption installations commissioned from 2026 onwards.
- Cantonal grants: these vary from canton to canton (Geneva, Vaud and Valais have their own schemes).
- The tax deduction: the net cost of the installation is generally deductible from your taxable income.
All in all, the net cost of an installation can come down by 25 to 40% compared with the advertised price. Subsidy amounts change every year: you can estimate your one-time remuneration with Pronovo's official tariff calculator, and find all the details in our complete guide to Pronovo subsidies 2026.

The real calculation is not just about the initial cost. A solar installation is an investment that produces electricity for 25 to 30 years. Three factors determine its profitability:
- Self-consumption: the electricity you produce and use directly saves you from buying it from the grid. The more you self-consume, the more profitable the installation.
- The feed-in tariff: the surplus fed into the grid is paid for by your local grid operator, at a rate that varies from region to region.
- Electricity price trends: every rise in grid tariffs automatically increases the value of your production.
In French-speaking Switzerland, the payback period is generally between 8 and 14 years. After that, the electricity produced is essentially free for the rest of the installation's lifetime.
Should you choose the cheapest option?
Over a 25-year investment, the lowest price is rarely the best choice. Entry-level equipment, sloppy installation or an inexperienced installer can prove costly in the long run: lower yield, breakdowns, waterproofing problems, warranties that are hard to enforce.
For any home, consistency between the quality of the property and that of the installation matters as much as the price. A well-integrated panel, a reliable inverter and flawless installation preserve both the performance and the value of your property.
Frequently asked questions about solar prices
How much does a solar installation cost in Switzerland in 2026?
For a villa, allow between CHF 18'000 and CHF 26'000 for 8 to 10 kWp turnkey, and from CHF 28'000 to CHF 48'000 for 12 to 20 kWp, before subsidies. After the one-time remuneration, the cantonal grant and the tax deduction, the net cost falls by 25 to 40%.
What is the price per kWp in French-speaking Switzerland?
Between CHF 1'800 and CHF 2'200 per kWp for a standard installation, and between CHF 2'200 and CHF 2'800 for premium equipment. Below 6 kWp, fixed costs push the price above CHF 2'800 per kWp.
How much does an installed solar panel cost?
A 430 to 450 Wp panel works out at around CHF 800 to CHF 1'100 installed, including inverter, mounting, connection and paperwork. The unit price means little: what counts is the price per kWp of the complete installation.
How much is the Pronovo subsidy for 10 kWp?
In 2026, the one-time remuneration is CHF 360 per kW for an added installation, i.e. CHF 3'600 for 10 kWp, and CHF 400 per kW for an integrated installation. In Geneva, the SIG solar bonus adds a further 25%.
What is the real cost after subsidies?
For 10 kWp at CHF 22'000, the one-time remuneration of CHF 3'600 brings the bill down to CHF 18'400; in Geneva, the SIG bonus brings it down to CHF 17'500. Deducting the net amount from your taxable income then reduces your income tax, often by 25 to 35% of that amount.
How long does it take for a solar installation to pay for itself?
In French-speaking Switzerland, the payback period is between 8 and 14 years, depending on the share of electricity you self-consume and your grid operator's feed-in tariff. The installation itself produces electricity for 25 to 30 years.
How much does a heat pump cost in Switzerland?
An air-to-water heat pump installed in a villa generally costs between CHF 25'000 and CHF 40'000, and more for a geothermal system. Our heat pump guide details the prices, the subsidies and how to pair it with solar.
In summary
For a quality solar installation in French-speaking Switzerland in 2026:
- Price per kWp: CHF 1'800 to CHF 2'800 depending on the range and size
