Swiss solar in 2025: what homeowners are buying now
25,562 new home systems, batteries up 70%, and new rules that make every kilowatt-hour used at home more valuable. The year in numbers.
Swiss homeowners kept going solar in 2025, and what they bought changed. Systems got bigger, batteries took off, and the rules around self-consumption shifted in favour of using solar power at home. Here is the year in numbers, from Swissolar and the Federal Office of Energy.
The year in numbers
| 2025 | Figure |
|---|---|
| New solar installed | 1,333 MW |
| New single-family home systems | 25,562 |
| Average home system | 13.4 kW |
| Battery storage sales | up more than 70% |
| Solar share of electricity use | 13.7% |
After the record year of 2024, the market settled into a steadier pace, and Swissolar expects it to stabilise in 2026, with solar covering close to 17% of Swiss electricity use. In its business survey, most companies expected higher revenue in 2026 than in 2025.
Batteries are the story of the year
Battery sales grew by more than 70% in 2025. Homeowners want to use more of their own power, and battery prices have come down: in the federal price study, small batteries under 10 kWh sold at a median of CHF 686 per kWh, and 20 to 30 kWh units at CHF 504 per kWh.
Why using power at home pays more
Since 1 January 2026, the payment for solar power fed into the grid is the same across Switzerland. It follows the quarterly average market price, with a minimum of 6 Rp./kWh for systems under 30 kW. A typical household, meanwhile, pays 27.7 Rp./kWh for power from the grid in 2026, according to ElCom.
So every kilowatt-hour a household uses itself is worth several times what it earns when exported. That makes self-consumption the heart of a good offer: a system sized to the home, a battery where it helps, and loads like a heat pump or an electric car running in the sunny hours.
New ways to share solar power
Since 2026, neighbours can form local electricity communities (LEG) and share solar power across a municipality using the public grid, with a discount on grid fees. Together with the virtual self-consumption groups (vZEV) available since 2025, this opens new options for homes with good roofs.
What this means for installers
- Lead with self-consumption. Show how much of the power the household will use itself, and what that saves.
- Offer the battery as an option with real numbers. Prices have come down and interest is high.
- Talk about the whole home. Heat pumps, EV charging and solar work best together.
- Reply fast. Homeowners comparing offers remember the installer who called first.
