How much does a solar installation cost for a house in Switzerland?

Expect CHF 12,000 to 18,000 for a 4 to 6 kWp system, the typical size for a single-family home. For a larger home (8 to 10 kWp), the budget rises to CHF 18,000 to 25,000 before subsidies.

What subsidies can I get?

The Pronovo one-time payment covers CHF 300 to 400 per installed kWp. Most cantons in Western Switzerland (VD, GE, FR, VS, NE, JU) add complementary grants. In total, subsidies often cut the bill by 20 to 30%.

How long until the installation pays for itself?

Usually between 8 and 12 years, thanks to self-consumption and selling surplus power. Panel prices have halved in 10 years, which significantly improves the return on investment.

Is a storage battery worth it?

A 10 kWh battery costs CHF 8,000 to 14,000. It increases your self-consumption rate but extends the payback period. It mainly makes sense if your consumption is high in the evening.

Solar installation prices in French-speaking Switzerland

Installing photovoltaic solar panels in Switzerland is a profitable investment thanks to federal and cantonal subsidies. Prices have dropped by 50% in 10 years and the return on investment is between 8 and 12 years.
