Daniel Leifheit responded quickly to inquiries and tried to offer a solution for every request as quickly as possible. Basically, he gave very customer-oriented advice.

Competent advice without a lot of talking - short and straight to the point.

I had already dealt quite intensively with the topic of photovoltaic systems and therefore had quite in-depth, specific questions. It became clear that he had the technical expertise, which was often not the case with offers and advice from other manufacturers. I was offered high-quality products, which was what I wanted. However, a Chinese alternative was also offered so that I could decide according to my own preferences. Although the highest quality components were offered, this was not the most expensive offer. Also, the contact was always very friendly and helpful, even though I had a lot of questions.

Very good response speed to customer queries, always very competent and easy to understand explanations Can only recommend to anyone!

The house on which the installation is being realized was built in 1994. Since then, I have had to award several contracts for the house, and I have always obtained at least two comparative offers. Your company, Mr. Leifheit, was the first potential supplier I approached. After contacting him, I decided to forego further offers for the first time. I think that shows that he does his job really well :)

Very sociable when giving advice, even if it takes a little longer or becomes more complicated. Competent demeanor, inspires confidence.

An offer adapted to the location was made.

Very helpful and always available. Professional 👍👍👍👍

We found Mr. Leifheit to be very competent. He responded to our questions/concerns and accepted requests for changes. He took his time for us. Written queries were answered quickly and to our complete satisfaction. Based on this positive experience, we have already recommended Energiemax to others.

Very pleasant contact. Competent and fair advice and in comparison with other companies with whom I have had discussions, definitely achieved the greatest optimization of the available roof space.

Mr. Leifheit was competent in all respects and I was very satisfied. I hope that his competence will be passed on to all subsequent employees, especially in the implementation and execution of the order,

very competent and technically very good advice for a layman. We hope the realization will be the same.

We were more than satisfied with the advice we received from Mr. Leifheit. He fully tailored his offer to our needs and thus configured the optimum, cost-effective system for us. His competence, patience and friendliness are reason enough for us to recommend EnergieMax GmbH to others. D. and R. Berg

We can only assess the services as laymen, as we do not have an overview of the entire market. We are not familiar with industry standards and are therefore unable to assess them. Nevertheless, we are very satisfied with the consultation and hope that the realization of the order will be of equally high quality.

...very competent advice, a very good recommendation from a colleague...

Very quick feedback Always available Good exchange of content

I felt very well advised by Mr. Leifheit. He seemed very competent and thorough and answered my questions in detail and gave good reasons for his decisions and recommendations.

Open and honest advice.

I was very satisfied with Mr. Leifheit's consulting services and now expect the planning to be implemented just as professionally. My expectation is that the system will work according to the simulations. Only when this has been verified can a final assessment be made.

Appointments also possible at short notice, available for queries at any time
