Kölner Solar Profis GmbH

I am extremely satisfied with the Cologne solar experts. The staff were very friendly and helpful and implemented my wishes exactly as I had envisioned.

The Cologne solar experts did a fantastic job for us. The installation of the system in our four-unit building went smoothly. From the initial consultation to the completion of the work, we felt we were in excellent hands. All our requests were handled promptly. The team was very friendly, competent, and helpful. The installers worked neatly and professionally. We highly recommend them! Thank you!

From the initial consultation to the final commissioning of the photovoltaic system, everything went absolutely smoothly. The team was highly competent and friendly, and they took plenty of time to explain everything clearly. I particularly appreciated the honest advice without any sales pressure, as well as the transparent cost breakdown. The installation was completed on schedule, cleanly, and professionally. Even after the installation, customer service was always available and helpful. You can tell that they work with experience, quality, and passion. I am more than satisfied with the service and the result, and I'm delighted to now be producing a large portion of my own electricity. I can wholeheartedly recommend this company!

⭐⭐⭐⭐⭐ Highly recommended – competent, reliable, and customer-focused I am completely satisfied with my collaboration with Kölner Solar Profis GmbH.

A complete package. I was looking for a company to install a heat pump and another to install a solar thermal system. I ended up finding the Cologne Solar Experts, who handled both for me. While not everything went perfectly, I was more than satisfied overall, from the initial order processing to the final installation. Clean work at fair prices. No hidden costs or surprises. The price was negotiated and honored, no ifs, ands, or buts. In the end, there was still enough budget left over to also have four split air conditioning units installed! I would gladly use them again. I highly recommend the Cologne Solar Experts. Thank you!!
