Feed-in tariff

31.12. 69 days left

Connect in 2026 and lock in 20 years of fixed feed-in payments

Under the government draft of 29 July 2026, new systems lose the fixed feed-in tariff from 2027. Systems running by 31 December 2026 keep it for 20 years. The law has not been passed yet.

After you order, we usually install within 4 weeks.

    One quote with all costs, components and the expected yield.

  4. 04

    Our installers build the system. We register it with the grid operator and the national register (Marktstammdatenregister).

  5. 05

    Aftercare

    We keep an eye on the system and come out when something is wrong.

Frequently asked questions

Is solar still worth it without a fixed feed-in tariff?

Yes, if you use the power yourself. Every kilowatt-hour you use replaces power you would otherwise buy, and that costs several times the feed-in tariff. With a battery, our customers reach 50 to over 85 percent self-sufficiency. Systems running by the end of 2026 also get 20 years of fixed feed-in payments under the government draft.

Do I need a battery?

Not always. A battery pays off if you use a lot of power in the evening and at night, for example for a heat pump or an electric car. If you like, our quote shows both options, with and without a battery.

How much does a solar system cost?

A 10 kWp system without a battery starts at €14,999 with us, including installation and registration with the grid operator. A battery, a difficult roof or a new meter cabinet add to that. Your quote shows every cost. Systems for residential buildings carry no VAT. As of 23 October 2026.

How long until the system is running?

After you order, we usually install within 4 weeks. We register the system with the grid operator and the national register (Marktstammdatenregister).

What happens if the system stops working?

You call your adviser directly and we take care of it. We look after your system after installation too.

Do you advise in English?

Yes. Advice and all the back-and-forth work in English or German. We handle the German forms for the grid operator and the authorities for you.

Are there subsidies?

There are national subsidised loans and, depending on your town, local programmes, for example for batteries. We check what applies to you and help with the application.
