Subsidies for
solar installations
in Switzerland
The federal government supports the expansion of photovoltaics with the one-time payment (OTP). This directly reduces your investment costs and makes solar energy economically attractive.

Prices from independent installers, turnkey including installation and VAT, without battery storage. Local electricity utilities generally charge more.
One-time payment (OTP)
What is the one-time payment?
The one-time payment is the main federal subsidy for photovoltaic installations in Switzerland. It is provided by the Confederation and managed by Pronovo.
You receive the payment once after the installation and registration of your system — no annual application, no bureaucratic burden.
KLEIV
Small one-time payment
For smaller installations — most commonly used for private detached houses.
GREIV
Large one-time payment
For larger installations — e.g. apartment buildings or commercial properties.
Subsidy overview
How much is the subsidy?
The OTP amount depends on commissioning date, system size, system type and any applicable bonuses. Pronovo calculates it for each installation. Check with Pronovo →

OTP payment
The one-time payment is usually made a few months after registration.
Calculation example
Example for a detached house
A 10 kWp system on the Swiss Plateau produces approximately 9'500 to 10'000 kWh per year.
Solar installation cost (10 kWp)
19'000 to 24'000 CHF
OTP amount
Calculated for the specific installation by Pronovo.
Profitability
Is a solar installation worth it despite the investment costs?
Thanks to government subsidies and electricity savings, a solar installation is worthwhile for many Swiss households. On the Swiss Plateau, systems pay for themselves within 9 to 13 years and modules last 25 to 30 years.
The actual profitability depends on the following factors:
Household electricity consumption
Self-consumption rate
Solar installation size
Electricity price trends
