After the storage system was installed in 2024, we commissioned Trend Energietechnik to expand our existing system. Overall, we are very satisfied with both the expert advice we received during the planning phase and the professional execution of the construction work.

Recommendation
The entire TREND team did a very good job in all areas.
The information event at the beginning answered our open questions and opened up new possibilities for us.
The quotations (for 2 PV systems) are precise and detailed.
The components, the work and the prices are precisely described and can always be assigned.
The individual installation jobs are announced in good time and the deadlines are easy to plan. Changes, even at short notice, are taken into account.
The work of the installation teams is carried out punctually, quickly and accurately. Even in very bad weather.
Questions to the office team are answered quickly and completely.
We are very satisfied with all the work carried out and can only recommend TREND Energietechnik to others.
Thank you very much for your excellent work.

Trend fully complied with my request to source the components for the PV system as far as possible from German manufacturers and offered these components (Mayer-Burger modules and SMA Home Storage) as an alternative. This gave me a direct cost comparison. The complete installation service from a single source, including coordination with the scaffolders, was super! Thank you for that. I can and will recommend Trend to anyone who wants to drive their own energy transition forward.
