Wir können Solarinnovation.ch und insbesondere Jordan für seine kompetente Beratung und perfekte Umsetzung als zuverlässigen Partner für nachhaltige Energielösungen aus einer Hand von Herzen weiterempfehlen. Er hat uns mit seinem umfangreichen Fachwissen von der ersten Beratung bis und mit der Umsetzung kompetent begleitet. Er hat alle Fragen immer verständlich erklärt. Wir sind mit der Indach-Solaranlage, kombiniert mit einem Speicher sehr zufrieden.

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.
How much does a solar system for a single-family home cost?
It depends on roof area, orientation and whether you want a battery. We clarify this on site during the free visit. The binding quote follows within 72 hours.
What subsidies are available?
The federal one-off payment (Pronovo), and many cantons and communes add their own. We check every programme for your address and can pre-finance the subsidy on request.
Is a battery worth it?
A battery typically raises self-consumption from around 35 to around 70 percent. Whether it pays off, we show you with your real consumption data.
What is a ZEV?
In a self-consumption community (ZEV), several households in one building share the solar power. We plan metering, contracts and billing.
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.
The first step
We come to you. Free of charge.
We check your roof, electrical system and consumption. Afterwards you know what is possible on your roof, what it costs and which subsidies you receive. The binding quote follows within 72 hours.
