With a solar power system from 1KOMMA5°, you benefit from installation and service from a single source, decades of experience and our smart energy manager Heartbeat.

Impact

Six Reasons for You to buy a Solar Power System

1. Free power supply provided by the sun

Once your system is installed, there are no further costs for operating your solar system.

2. Energy independency

Depending on the size of your system and your energy consumption, you can produce part or even all of your own energy, making you more independent from energy providers and giving you more control over your energy costs. Combining with a power storage system can further maximise your energy independence.

3. Climate protection

While using the sun’s energy solar power systems reduce dependency on fossil fuels and eventually decrease greenhouse gas emissions. Installing a solar system offers an easy way to reduce your carbon footprint and make a direct contribution to climate protection.

4. Future-proof

With our solar power system, you have up to 25 years of warranty and the average lifespan of a solar system is even higher. With a fully equipped energy system including a solar power system, power storage, Wallbox, heat pump, and our smart energy manager Heartbeat, you can connect your home with all our customers, transforming it into a virtual power plant. With this technology, you are equipped and secure for the next decades.

5. Feed-in tariffs

The feed-in tariff is a policy mechanism that provides financial incentives to individuals and organisations for generating renewable energy and feeding it back into the grid. 

It is only available in a few specific countries which can be found in Europe, North America and Australia. In Europe, for instance, Germany, France, Spain and the UK offer feed-in tariffs. 

Inform here about the feed-in tariffs in Germany.

6. Increase the value of the property

Energy savings and feed-in tariffs help recoup your investment, and in the long run, also increase your property value. Homebuyers seek energy efficiency and sustainability, and a solar system is a clear indication of this.

You may also benefit from government incentives and tax breaks in certain areas, further reducing the financial impact. In short, a solar system can be a financially rewarding investment that increases your property value.

Step 1

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.
