Solar Panel Calculator for Switzerland
Rooftop solar is well supported in Switzerland through a one-time investment grant. This free solar calculator estimates your system size, payback and savings in francs using local rates and sun hours.

Solar at a glance in Switzerland
The one-time grant plus high retail prices keep payback reasonable despite moderate winter sun.
| Currency | Swiss francs (CHF) |
|---|---|
| Typical electricity rate | CHF 0 per kWh |
| Installed cost | ≈ CHF 3 per watt |
| Peak sun hours | ≈ 3.2 hours/day |
| Rooftop subsidy / credit | ≈ 25% (indicative) |
| Export / buyback | ≈ CHF 0 per kWh |
Indicative 2026 starting points — every figure is editable in the calculator, and results depend on your own bill, roof and installer quotes.
A typical 5 kW system in Switzerland
At around CHF 3 per watt, a 5 kW rooftop system costs roughly CHF 12,500 and produces about 4,555 kWh in its first year at Switzerland's 3.2 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
- Your setup. Switzerland and Swiss francs are pre-selected, with local electricity rate, install cost and sun hours filled in. Enter your monthly bill, or size the system from your appliances.
- Your roof. Search your address or tap “use my location”, then draw your roof on the satellite map — or just type its area. We check the system fits and read local sun hours from NASA data.
- Your results. Instantly see your payback period, net savings, ROI, system size, year-1 production and lifetime CO₂ offset — compare cash vs. a loan, and download a PDF report.
Common questions — solar in Switzerland
How many solar panels do I need in Switzerland?
It depends on your electricity use, roof space and local sun hours (about 3.2 peak sun hours/day here). A 5 kW system of high-wattage panels is a common starting point for a home — enter your bill or appliances and the calculator gives your exact panel count and system size.
Does Switzerland have net metering?
Switzerland uses self-consumption plus feed-in — surplus is bought by your grid operator at a rate that varies locally, while self-consumed power offsets retail price. The calculator models the feed-in as buyback.
Are there solar subsidies or incentives in Switzerland?
A federal one-time remuneration (Einmalvergütung / EIV) covers a meaningful share of a small system's cost; some cantons add more. Enter your effective rebate percentage.
How much does a solar system cost in Switzerland?
A typical 5 kW system is around CHF 12,500 at about CHF 3 per watt installed before the one-time grant. The calculator prices your exact size.
