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.

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 subsidy is typically CHF 300–400 per kWp of installed capacity. The larger the installation, the higher the amount.
Indicative values. The exact amount depends on the current subsidy structure and the system size.
Additional support
Cantonal subsidy programmes
In addition to federal support, many cantons offer additional programmes. The available subsidies differ from canton to canton.

Process
How do I get the subsidy?
Installation
Have the photovoltaic system installed by a certified installer.
Registration
Register the system with Pronovo (pronovo.ch) — the installer often handles this for you.
Review
The relevant authorities review the installation and documentation.
OTP payment
The one-time payment is usually made a few months after registration.
Calculation example
Example for a detached house
Many detached houses install a system of 8–10 kWp, producing approximately 8,000–10,000 kWh of electricity per year.

Profitability
Is a solar installation worth it despite the investment costs?
Thanks to government subsidies and rising electricity prices, a solar installation is worthwhile for many Swiss households. Most systems pay for themselves within 10–15 years with a lifespan of 25–30 years.
The actual profitability depends on the following factors:
Household electricity consumption
Self-consumption rate
Solar installation size
Electricity price trends
