I've decided on a solar system, which will be installed in May, and I'm very happy with the advice I've received so far. From the very beginning, I've been treated with friendliness and expertise, and all my questions have been answered patiently and clearly. I especially appreciated that my individual needs were taken into account and that they took the time to find a suitable solution. Overall, I feel I'm in excellent hands and am really looking forward to the implementation of my project.
I would like to share my thoroughly positive experience with Ecosun (formerly SpahiuTec) after they installed our solar panels and battery. Everything went perfectly from the start. The price was absolutely fair and transparent, the project was carried out professionally and quickly, and the entire team was always friendly and helpful. I would particularly like to highlight how easily they handled a minor issue – some modules were accidentally left out during the initial installation. It was impressive that they immediately acknowledged this problem and delivered and installed the missing modules free of charge within just a few days. This quick and customer-oriented solution impressed us greatly and demonstrated that service and reliability are top priorities for them. Overall, we are more than satisfied with the entire project and its outcome. We can wholeheartedly recommend Ecosun and thank them sincerely for the excellent collaboration!
In autumn 2024, ecosun installed our photovoltaic system, including storage, which had a few unique features. All of this was done with genuine friendliness, speed, and expertise! The challenges posed by the separate installation from the house were easily resolved without incurring any additional costs. Hats off to them! We can definitely recommend this company. This is how the future should be!
My PV system was installed and commissioned very professionally, quickly, and pragmatically. Ecosun was very friendly. I really didn't have to worry about a thing. Highly recommended!
Excellent service from the whole Ecosun team - installing a 24 panel Photovoltaic system in our house without any glitches. The team was competent, responsive and very pleasant to work with. I can highly recommend them.
