We would like to sincerely thank DSS and offer our unqualified recommendation. From the initial contact to the (unfortunately unsuccessful) contract signing, it was an entirely positive experience for us. The consultation was exceptional – we have never experienced such a thorough, honest, and transparent consultation before. No questions remained unanswered, and at no point did we feel that the focus was solely on a quick contract signing. Quite the opposite: When our consultant noticed a slight skepticism in our eyes, he took the time to explain everything again in minute detail – patiently

Mr. Galletti's personal consultation at our home began with him asking about our expectations regarding photovoltaics. We've had experience with other companies who, during video calls, offered us a project we didn't actually want; their sole focus was maximizing their profit. The three DSS installers did their work quickly and efficiently, and they discussed everything with us beforehand.

Overall, I'm very satisfied with DSS. Everything went smoothly, from the initial consultation to the commissioning. In some ways, it even went too quickly for my liking. The system was installed on the roof during my vacation instead of afterward, but even that didn't cause any significant problems.

Mr. Galletti personally provided me with very efficient advice today, even though I'm not a customer. He simply calculated the key figures (data, figures, facts) for my existing system and gave me some great tips. If I didn't already have a system, I would definitely choose this company. As a former Quality Management Representative, I hereby award them full marks.
