GST Germanium Solartechnik GmbH

I met GST Germanium Solar Technik at a construction trade fair in Darmstadt. The initial contact was friendly, clear, and technically convincing. GST works precisely and systematically. They measure the roof area using a drone and inspect the existing electrical installation on-site. This provides a solid foundation for planning. The PV system planning was easy to understand. GST presents you with several options and explains the advantages and disadvantages straightforwardly. Every decision remains transparent. The installation was quick and professional. The team works cleanly, reliably

At the 2025 Darmstadt Building Trade Fair, we discovered GST Germanium Solartechnik GmbH at the end of our visit. We encountered a very thoughtful employee who reacted with great care when he saw the aerial photograph of our roof. Since we were rather skeptical about the roof's potential (three-story older building, overhanging mansard roof, small steep roof surfaces, dormers, beaver tail tiles, etc.), this reaction seemed very appropriate. The outdated electrical system also needed to be brought up to date. From this initial contact until the system's completion, we felt very well supported.

Wir haben uns für die Firma GST Germanium Solartechnik entschieden, nachdem wir auf einer Baumesse auf sie aufmerksam geworden sind. Schon auf der Messe haben wir uns gut beraten gefühlt. Beim Vor-Ort-Termin wurde durch professionelle Ausrüstung die Dachfläche vermessen und für scheinbar Unmögliches, Lösungen gefunden. Vor kurzem haben wir den Speicher erweitert, da wir die meiste Energie selber verbrauchen möchten, das E-Auto jedoch erst abends zu Hause ist und dadurch Strom ins Netz gespeist werden musste. Auch hier wurden wir gut beraten, die Nachrüstung konnte kurzfristig durchgeführt werd

We first became aware of Germanium Solartechnik through a construction trade fair. The initial consultation made a very good impression. The subsequent on-site consultation confirmed this positive impression. We had several solar companies on site, and GST was the only one who pointed out the required distances between the modules and the neighboring house. The other consultants didn't take this so seriously and even wanted to use the neighbor's roof to accommodate the modules. Therefore, the choice for Germanium Solar was not difficult, and we commissioned the installation. To my surprise, th

I would like to share my experience with GST Germanium Solartechnik. The team did a fantastic job! From the initial contact to the follow-up support, we were completely satisfied. Even now, we can still call our contact person if we have any questions. The PV system has been working flawlessly since day one. Despite the rain and hardly any sunshine last week, we are producing our own electricity and are very happy about it. We are extremely satisfied and happy to have chosen GST Germanium Solartechnik.
