6 Reasons to Enhance Your Solar System with an Energy Storage Unit

Step 1

We advise you personally.

Our energy advisors will create an individual offer based on your data. We will explain everything about subsidies, energy management and your individual energy solution.

Step 2

We install your solar energy storage system.

If you are satisfied with the planning of your solar system, we will arrange an installation date after conclusion of the contract, at which time our team will install and commission everything on your premises.

Step 3

We stay by your side.

Even after installation, we remain your long-term partner. Whether you have questions about energy, warranty issues or service, we want to be your contact for the expansion of your energy system with a heat pump or wallbox.

Testimonials

Join the 1KOMMA5° Movement

Take the lead in climate protection - hear from our customers on how they are making a difference.

We decided to go solar for several reasons: for ecological reasons, for political reasons, to be more independent and to please our children.
Zilian Family
I already knew the Göttingen location before it became part of the 1KOMMA5° Group. The team from Göttingen then informed and advised us, so that we decided on a solar system from 1KOMMA5°.
Sybille Fichte
I heard about 1KOMMA5° through a neighbour and in fact another neighbour has now also opted for 1KOMMA5° as a result of the installation at my house.
Dr. Josef Frasunek
We wanted to become more independent. Also from the electricity market. We asked various suppliers and 1KOMMA5° was able to deliver the fastest.
Mecke Family
That was an investment in the future! I want to produce free electricity on my own roof.
Guido Kahlmeyer
I would recommend my friends to think about environmental protection: What can I do personally? For example, buy a photovoltaic system. That way I'm doing something for the environment.
