Solar Tech Nordrhein-Westfalen

I can wholeheartedly recommend SolarTech from Cologne. My contact person, Mr. Schubert, was always very reliable, friendly, and competent, and always had an open ear for all my questions and concerns. A Viessmann heat pump was installed at our home, which works extremely efficiently and to our complete satisfaction. I can also only praise the installers highly. They worked very cleanly and professionally. Thank you very much, and I look forward to future projects together!

We are very satisfied with the consultation and installation of our heat pump. Our consultant, Mr. Losso, in particular, provided highly competent and easy-to-understand advice and took the time to answer all our questions. The installation was completed on time, cleanly, and professionally. Overall, a very positive experience – we would definitely recommend Solar Tech Nordrhein-Westfalen and Mr. Losso.

Everything went perfectly! Mr. Bröcher's consultation and construction supervision were excellent. Good value for money. Installation was top-notch. And if you have any further questions, Mr. Bröcher is always available. We can wholeheartedly recommend Solartech-NRW in every respect.

We can wholeheartedly recommend Solartech without reservation. After receiving several quotes, I was fortunate enough to get a tip from a colleague. Mr. Müller then perfectly planned our system and convincingly allayed my concerns, as our house is quite old. What more can I say? Two weeks after our initial contact, the modules were on the roof, and another week later, the electrician was here. The planning, execution, and support were superb. If anything is unclear or you have questions, a simple call to Cologne or directly to Mr. Müller is all it takes, and you'll receive prompt, friendly,

I would gladly give more than 5 stars!!! What can I say? Following a tip from an acquaintance, Mr. Sören Müller came to our home and gave us comprehensive advice, which convinced us of the benefits. In short, the system was installed on the roof a few days later, and the electrician arrived a week after that. The tradespeople were very careful with our property, worked cleanly, finished quickly, and we always had the impression that they knew what they were doing. Mr. Müller was always readily available and friendly, questions were answered immediately, and SolarTech even took care of all t
