Testimonials

Seeing our customers satisfied is our main objective.

Donauer's initial approach was very important for me to give renewable energy a chance. Then a relationship / a partnership connection started to be created between the supplier and the customer which increased over time. Donauer excels in their work to always present the best solutions and the best prices.

Boa Energia Director

Generally speaking, the installer knows that there are issues that don't go so well and so he values the fact that people put their faces out there and have the spirit to help when there are problems, so he identifies with Donauer's way of being, their seriousness.
