Solar power in Frauenfeld: what you should know

Electricity price and grid operator

Frauenfeld is supplied by Thurplus. A household using 4,500 kWh a year pays 29.5 ct./kWh excluding VAT in 2026, 31.9 ct. including VAT. That is 1.8 ct. above the Swiss median and 0.1 ct. above the median in the Canton of Thurgau.

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 Frauenfeld

According to the Swiss Federal Office of Energy, the roofs in Frauenfeld could deliver around 191 GWh of solar power a year, 6,905 kWh per person. Today 17.8% of it is used, compared with a Swiss average of 12.8%. That puts Frauenfeld above the Swiss average.

Of the 4,784 residential buildings, 2,870 are single-family homes and 1,263 are apartment buildings.

According to MeteoSwiss, hailstones of 3.5 cm are to be expected in Frauenfeld 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 Thurgau for notification, subsidies and tax deduction is on the page Solar installation in the Canton of Thurgau. We register the system and submit the subsidy applications. On request, we pre-finance the subsidies.

70.0% of residential buildings in Frauenfeld 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.

Your question is not listed?

044 980 08 80info@solarinnovation.ch
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.

What does electricity cost in Frauenfeld?

With Thurplus, a household using 4,500 kWh a year pays 29.5 ct./kWh excluding VAT in 2026, 31.9 ct. including VAT (ElCom).

Is a solar system worth it in Frauenfeld?

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 890 of grid power a year at the Thurplus 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 Frauenfeld for a site visit?

Yes. Frauenfeld is around 32 km from our location in Zumikon. 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 Thurgau?

Mostly not. You notify the commune of sufficiently well-integrated systems with an area of 35 m² or more. Smaller systems in the building zone need neither notification nor a permit. A permit is still needed for around 10% of buildings, for example in ISOS areas with conservation objective A and for protected individual objects.

How do I find out in the Canton of Thurgau whether my roof needs a permit?

The solar map in ThurGIS shows for every building whether a permit is needed or a notification is enough. We check it for your address at the site visit.

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.
