GFK Solar Installation GmbH

I'm very satisfied. I wasn't used to having direct phone contact during my house construction, and even having them call back – here it always worked perfectly. The planning and execution were also excellent. I wasn't pressured into any unnecessary extras, and in fact, I was advised against unnecessary things. Fantastic. There was a communication problem between the battery and the inverter, which prevented the battery from working, but after the owner himself and the electrician worked overtime on Friday evening, everything worked out in the end.

From the initial inquiry to the completed solar system, everything went perfectly. The consultation was detailed and honest, so we immediately felt confident. During the installation, the team was reliably friendly and worked very cleanly. We particularly liked the fact that all processes were clearly explained and we always knew what would happen next. Now the system is running smoothly, and we enjoy our own electricity every day.

A huge thank you to the entire GFK Solar team! From the initial consultation to the final handover of the system, we felt completely well taken care of. We would particularly like to highlight the smooth installation process. Our rather complicated roof had already deterred a few companies who never got back to us, but the guys at GFK Solar tackled the project and saw it through! Communication was always friendly and professional, and any questions were answered promptly. The handover was well-organized, including a thorough introduction to the app. Our conclusion: A company that knows its cra

I was pleasantly surprised by how personal and straightforward everything was. From the initial contact to the completed installation, nothing felt like a standard process, but rather like individualized service. The staff were friendly, attentive, and always ready to explain things. Even after installation, the service remained excellent, and we received prompt assistance with a minor question about the app. This is what truly excellent customer service should be like.

Even during the consultation, I had the feeling that the people working here really know what they're doing and enjoy their work. Everything was explained clearly, and we were able to decide together what would be best for our house. The installers were punctual, friendly, and did an extremely clean job. The system has been running perfectly for a few weeks now, and we're really happy with the results.
