Solar power in Derendingen: what you should know
Electricity price and grid operator
Derendingen is supplied by Regio Energie Solothurn, some parts also by EWD. A household using 4,500 kWh a year pays 30.0 ct./kWh excluding VAT in 2026, 32.4 ct. including VAT. That is 2.3 ct. above the Swiss median and 0.4 ct. below the median in the Canton of Solothurn.
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 Derendingen
According to the Swiss Federal Office of Energy, the roofs in Derendingen could deliver around 50 GWh of solar power a year, 6,768 kWh per person. Today 12.8% of it is used, compared with a Swiss average of 12.8%. That puts Derendingen above the Swiss average.
Of the 1,483 residential buildings, 943 are single-family homes and 320 are apartment buildings.
According to MeteoSwiss, hailstones of 3.5 cm are to be expected in Derendingen 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 Solothurn for notification, subsidies and tax deduction is on the page Solar installation in the Canton of Solothurn. We register the system and submit the subsidy applications. On request, we pre-finance the subsidies.
77.7% of residential buildings in Derendingen 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.
What does electricity cost in Derendingen?
With Regio Energie Solothurn, a household using 4,500 kWh a year pays 30.0 ct./kWh excluding VAT in 2026, 32.4 ct. including VAT (ElCom).
Is a solar system worth it in Derendingen?
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 900 of grid power a year at the Regio Energie Solothurn 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 Derendingen for a site visit?
Yes. Derendingen is around 79 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 Solothurn?
For roof systems, you submit the cantonal notification form with a building description, site plan and elevation plan to the building administration of your commune. The commune then checks whether the system needs only a notification or a building permit.
Is there a subsidy for photovoltaics in the Canton of Solothurn?
The cantonal subsidy programme does not list photovoltaics as a measure of its own. It supports the building envelope, heat pumps and solar thermal systems, among other things. For photovoltaics, the federal one-off payment applies.
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.
