Batteries: Worth considering.
Key insight: Solar economics in this country depend on the combination of electricity prices, solar yields, and available subsidies. Use the calculator for a personalized assessment.
Key Statistics
Electricity Prices (2025–2026)
| Tariff | Price | Notes |
|---|---|---|
| Standard residential | €0.29/kWh | Flat rate option available |
| Time-of-use peak | €0.32/kWh | Peak hours vary by supplier |
| Time-of-use off-peak | €0.22/kWh | Usually nights/weekends |
| Feed-in (export) | €0.12/kWh | What the grid pays for excess solar |
| Gas | ~€0.11/m³ | ~10 kWh/m³ |
kWh = kilowatt-hour: The unit on your electricity bill. A 1,000-watt appliance running for one hour uses 1 kWh. An average European home uses about 250–350 kWh per month.
Solar Potential
| Region | Solar Output per kWp | 5 kWp System Annual |
|---|---|---|
| Switzerland (average) | 1000 kWh/yr | 5,000 kWh |
kWp (kilowatt-peak): The maximum power a solar system can produce in perfect midday sun. A 5 kWp system = roughly 12–15 panels. Think of it as the "engine size" of your solar setup.
Switzerland has moderate solar potential. Typical for Central/Northern Europe.
Electricity Generation Mix
Understanding how Switzerland generates its electricity helps explain why solar is (or isn't) incentivised.
| Source | Share |
|---|---|
| Nuclear | 29.9% |
| Oil | 1.9% |
| Hydro | 52.3% |
| Solar PV | 12.1% |
| Biofuels | 1.6% |
| Other Renewables | 1.6% |
Source: Our World in Data (2025). Total generation: 65 TWh.
Hydro-dominated grid: Switzerland already has abundant renewable electricity from hydro. Solar adds value by generating in summer when hydro reservoirs may be lower.
Who Uses the Electricity?
| Sector | Share of Consumption |
|---|---|
| Industry | 29% |
| Residential (households) | 34% |
| Commercial & Public | 30% |
| Transport | 7% |
Subsidies & Incentives
| Program | Type | Status | Notes |
|---|---|---|---|
| Cantonal feed-in tariffs | feed-in | Active | Varies by canton. Typically 10-20 cts/kWh for 10-25 years. |
| One-time investment subsidy | grant | Active | Some cantons offer 10-30% one-time subsidy on PV systems. |
| Building program solar | grant | Active | Federal and cantonal building programs include solar incentives. |
Reference Model Results
Using our calculator with a 5 kWp system, 8,500 kWh annual demand, no battery:
| Metric | Value |
|---|---|
| Annual generation | 5,000 kWh |
| Self-consumption | 52.8% (2,641 kWh) |
| Export | 47.2% (2,347 kWh) |
| Self-consumed value | €766/year |
| Export value | €282/year |
| Gross annual saving | €1,048/year |
| Simple payback | 8.9 years |
| NPV (6%, 25 yr) | €2250 |
| Verdict | Excellent investment |
NPV: Net Present Value. Adds up 25 years of savings, discounted at 6%, and compares to keeping the money in the bank. Positive = solar beats the bank. Negative = you'd be better off investing elsewhere.
Battery Economics
Battery viability depends on whether time-of-use tariffs exist and the retail-to-feed-in price spread. Check the electricity price table above.
Country-Specific Considerations
Solar economics in this country depend on the combination of electricity prices, solar yields, and available subsidies. Use the calculator for a personalized assessment.
Grid Connection
- Typical connection: singlePhase25A
- Single-phase max: 5 kWp
- Export limit per phase: 10 kW
- Metering type: netTotal
- Net metering: Your generation offsets consumption across all phases (favorable)
- Net metering policy: no net metering; separate feed-in tariff
Red Flags for Switzerland Installers
- Promises payback significantly shorter than our model shows (reviewed 2026-05 — Installer claim monitoring)
- Doesn't mention actual feed-in/export rates (reviewed 2026-05 — Installer claim monitoring)
- Uses optimistic self-consumption (>70%) without battery or EV (reviewed 2026-05 — Installer claim monitoring)
- Doesn't include inverter replacement cost (reviewed 2026-05 — Installer claim monitoring)
- Doesn't include maintenance costs (reviewed 2026-05 — Installer claim monitoring)
- Pressure tactics ('subsidy ends soon!') (reviewed 2026-05 — Installer claim monitoring)
- Quotes without seeing your actual bills (reviewed 2026-05 — Installer claim monitoring)
When Solar Makes Sense in Switzerland
- ✅ You have high electricity bills (above average for your country)
- ✅ You're home during the day (retired, work from home)
- ✅ You have an EV and charge at home
- ✅ You can get available subsidies
- ✅ You value energy independence
Verdict Summary
| Strategy | Payback | Notes |
|---|---|---|
| 5 kWp solar only | 8.9 years | Excellent investment |
| With battery | Add 4–8 years | Worth considering |
| With subsidies | Subtract 1–3 years | Check current programs |
| With EV charging | Subtract 1–2 years | Increases self-consumption |
