Solar power in Wangen: what you should know
Electricity price and grid operator
Wangen is supplied by Gemeinde Wangen SZ, Elektrizitätswerk. A household using 4,500 kWh a year pays 33.5 ct./kWh excluding VAT in 2026, 36.2 ct. including VAT. That is 5.8 ct. above the Swiss median and 5.3 ct. above the median in the Canton of Schwyz.
Because grid power here costs more than the Swiss average, every kilowatt hour you use from your own roof is worth correspondingly more.
Roofs in Wangen
According to the Swiss Federal Office of Energy, the roofs in Wangen could deliver around 39 GWh of solar power a year, 6,861 kWh per person. Today 19.2% of it is used, compared with a Swiss average of 12.8%. That puts Wangen above the Swiss average.
Of the 1,267 residential buildings, 823 are single-family homes and 213 are apartment buildings.
According to MeteoSwiss, hailstones of 3.5 cm are to be expected in Wangen about every 50 years. This determines the hail resistance class of the modules.
Subsidies and permit
The federal government pays a one-off payment (Einmalvergütung) of CHF 360 per kW through Pronovo, so CHF 3,600 for a 10 kWp system.
What applies in the Canton of Schwyz for notification, subsidies and tax deduction is on the page Solar installation in the Canton of Schwyz. We register the system and submit the subsidy applications. On request, we pre-finance the subsidies.
38.5% of residential buildings in Wangen still heat with oil or gas. Anyone who later switches to a heat pump needs more power and uses more from their own roof.

Frequently asked questions
Before you get in touch.
Is the site visit really free?
Yes. The visit and the quote cost you nothing and commit you to nothing. You only decide once you hold the binding quote in your hands.

With Gemeinde Wangen SZ, Elektrizitätswerk, a household using 4,500 kWh a year pays 33.5 ct./kWh excluding VAT in 2026, 36.2 ct. including VAT (ElCom).
Is a solar system worth it in Wangen?
That depends on the roof and on your consumption. As a guide, a 10 kWp system produces around 10,000 kWh a year. If you use 30% of it yourself, you save around CHF 1,010 of grid power a year at the Gemeinde Wangen SZ, Elektrizitätswerk tariff. On top come the payment for the power you feed in and a one-off payment of CHF 3,600. At the site visit we calculate with your figures.
Do you come to Wangen for a site visit?
Yes. Wangen is around 3 km from our location in Lachen. The site visit is free and with no obligation, and you receive the quote within 72 hours.
Do I need a building permit for a solar system in the Canton of Schwyz?
For sufficiently well-integrated roof systems in building and agricultural zones, a notification through eBau is enough in the Canton of Schwyz. Protected buildings and areas with strong townscape protection need a permit procedure. A fire protection permit is needed in every case.
How early do I have to notify in the Canton of Schwyz?
The notification must be submitted in eBau at least 20 days before building work starts. If the commune does not object within that period, we can build. We submit the documents for you.
Which regions do you cover?
All of German-speaking Switzerland. We build most often in the cantons of Zurich, St. Gallen, Schwyz and Aargau. Our locations are in Zumikon ZH and Lachen SZ.
