How much does a solar installation cost in Switzerland?
The costs depend primarily on the system size, the roof area and the components used.
For a typical detached house, prices are usually between:
An average installation for a detached house has an output of approximately 8 to 10 kWp.
Solar installation costs for a detached house
Typical price ranges for photovoltaic systems in Switzerland
| System size | Annual electricity production | Roof area (approx.) | Cost (approx.) |
|---|---|---|---|
| 5 kWp | 4'750 to 5'000 kWh | 32.5 m² | 12'000 to 15'000 CHF |
| 8 kWp | 7'600 to 8'000 kWh | 52 m² | 17'000 to 21'000 CHF |
| 10 kWp | 9'500 to 10'000 kWh | 65 m² | 19'000 to 24'000 CHF |
Cost per kWp in Switzerland
The cost of a photovoltaic system is often calculated per kWp (kilowatt peak). In Switzerland, average costs are:
The price per kWp decreases for larger systems, as installation costs can be better distributed.
How much does a 10 kW solar installation cost in Switzerland?
A photovoltaic system with 10 kWp output typically costs in Switzerland:
gross cost before subsidies
Annual electricity production
On the Swiss Plateau, a 10 kWp system produces 9'500 to 10'000 kWh per year.
For a 10 kWp system, allow approximately 65 m² of roof area.
How much does a solar installation with storage cost?
Battery storage increases the cost of a solar installation – but it allows you to use more of your own electricity and feed less into the grid.
| Storage capacity | Cost (approx.) |
|---|---|
| 5 kWh | 3'500 to 5'000 CHF |
| 10 kWh | 5'500 to 7'500 CHF |
Storage can significantly increase the self-consumption of self-produced electricity.
Prices include installation and commissioning. If storage is added later without a hybrid inverter, an additional CHF 1'500 to CHF 3'000 applies. Indicative values, updated September 2026. Sources: Pronovo, ElCom, Swissolar.

The most important factors that determine the price of a solar installation in Switzerland
System size
Larger systems generally have lower costs per kWp, as installation costs are spread across more output.
Roof area
The larger the available roof area, the larger the system can be dimensioned.
Roof type
Flat roofs or complex roof shapes can result in higher installation costs.
Components
High-quality modules or inverters can increase the price but offer longer warranties and a longer service life.
Subsidies for solar installations in Switzerland
In Switzerland, the federal government supports photovoltaic systems with the one-time payment (OTP). This subsidy noticeably reduces investment costs.
Calculated individually
Pronovo determines the federal one-time payment based on the installation and applicable conditions.

Answers to the most common questions about the cost of a solar installation in Switzerland
What does a photovoltaic system cost for a detached house?
A 10 kWp solar installation costs 19'000 to 24'000 CHF before subsidies.
How much does a 10 kW solar installation cost in Switzerland?
A 10 kWp photovoltaic system costs 19'000 to 24'000 CHF before subsidies. On the Swiss Plateau it produces 9'500 to 10'000 kWh per year.
How much electricity does a solar installation produce?
On the Swiss Plateau, a solar installation produces 950 to 1'000 kWh per kWp per year.
Is a solar installation worthwhile in Switzerland?
On the Swiss Plateau, the indicative payback period is 9 to 13 years. Modules last 25 to 30 years.
How many solar modules does a detached house need?
The number of modules depends on the system size and the output of the selected modules.
How large does my roof need to be for a solar installation?
Allow approximately 6.5 m² per kWp. A 10 kWp system therefore needs about 65 m².
What subsidies are available for solar installations in Switzerland?
The federal one-time payment is calculated individually by Pronovo. Cantonal and municipal support may also apply. Check pronovo.ch for current conditions.
What does a solar installation with battery storage cost?
Battery storage increases the cost: 5 kWh costs 3'500 to 5'000 CHF and 10 kWh costs 5'500 to 7'500 CHF.
