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:

CHF 15,000 – 35,000
after deducting subsidies

An average installation for a detached house has an output of approximately 8 to 10 kWp.

Typical price ranges for photovoltaic systems in Switzerland

5 kWpCHF 13,000 – 18,000
Production: 4,500 – 5,000 kWh
Roof area: approx. 30 – 35 m²
Ideal for: Small house
Most popular size
8 kWpCHF 18,000 – 25,000
Production: 7,500 – 8,000 kWh
Roof area: approx. 50 – 55 m²
Ideal for: Detached house
10 kWpCHF 22,000 – 30,000
Production: 9,000 – 10,000 kWh
Roof area: approx. 62 – 68 m²
Ideal for: Large house / apartment building
These prices typically include: solar modules, inverter, mounting and installation. The actual price depends on the roof type, orientation and chosen components.

Cost per kWp in Switzerland

The cost of a photovoltaic system is often calculated per kWp (kilowatt peak). In Switzerland, average costs are:

CHF 1,800 – 2,800 per kWp

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:

CHF 22,000 – 30,000

after deducting subsidies

Annual electricity production

A 10 kWp system produces approximately 9,000 – 10,000 kWh of electricity per year in Switzerland. This is often enough to cover a large portion of a detached house's electricity consumption.

For a 10 kWp system you need approximately 62 – 68 m² of roof area and 20 to 25 solar modules.

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.

5 kWh
CHF 4,000 – 6,000
10 kWh
CHF 7,000 – 10,000

Storage can significantly increase the self-consumption of self-produced electricity.

What factors influence the costs?

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.

CHF 300 – 400 per kWp

Typical federal subsidy amounts (OTP). The level depends on the system size.

Calculation example: 10 kWp system

Gross costCHF 26,000
– One-time payment OTP (approx. CHF 350/kWp)– CHF 3,500
– Cantonal subsidy (example)– CHF 2,000
Effective cost (example)CHF 20,500

Reference value. Actual subsidies vary by canton and system size.

FAQ – Frequently asked questions about solar installation costs

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?

Most solar installations for detached houses in Switzerland cost between CHF 18,000 and CHF 30,000 after deducting subsidies (OTP). For a typical installation of 8 to 10 kWp, this is the usual price range.

How much does a 10 kW solar installation cost in Switzerland?

A photovoltaic system with 10 kWp typically costs between CHF 22,000 and CHF 30,000 in Switzerland. After deducting the federal one-time payment (OTP), the net costs can be noticeably lower. Such a system produces approximately 9,000 – 10,000 kWh of electricity per year.

How much electricity does a solar installation produce?

In Switzerland, a solar installation produces approximately 900 – 1,000 kWh of electricity per kWp per year. A 10 kWp system therefore generates around 9,000 – 10,000 kWh annually – often enough to cover a large portion of a detached house's electricity consumption.

Is a solar installation worthwhile in Switzerland?

Yes. Due to rising electricity prices and available subsidies, many installations in Switzerland pay for themselves within 10 to 15 years. With a lifespan of 25 – 30 years, that means years of free electricity from your own roof.

How many solar modules does a detached house need?

For a typical installation of 8 to 10 kWp, 20 to 30 solar modules are generally needed, depending on the module output (usually 400 – 450 watts per module).

How large does my roof need to be for a solar installation?

For 1 kWp of output, approximately 6 to 7 m² of roof area is required. A 10 kWp system therefore needs around 60 – 70 m² of suitable roof surface.

What subsidies are available for solar installations in Switzerland?

In Switzerland the federal government offers the one-time payment (OTP). Typical subsidy amounts are around CHF 300 – 400 per kWp. Additionally, many cantons and municipalities offer their own support programmes. The investment is also tax-deductible.

What does a solar installation with battery storage cost?

Battery storage increases the cost of the solar installation: a 5 kWh storage system costs around CHF 4,000 – 6,000, a 10 kWh system around CHF 7,000 – 10,000. With storage, the self-consumption of self-produced electricity increases significantly.

In brief

A solar installation in Switzerland typically costs:

CHF 15,000 – 35,000

for a detached house
