Carrying solar energy out from Hamlar into the world – Tradition meets innovative solar concepts

Our company based in Hamlar near Asbach-Bäumenheim, Germany, offers an innovative system for solar active façades, consisting of PV and solar panels, under the umbrella of the multinational Grenzebach Group. Since our founding as a manufacturer, a team of experienced experts from various fields of automation as well as the glass and solar industries have been working together on a common vision: to provide Germany, Europe, and the world with technology that will make it possible to generate renewable energy directly on buildings over the long term – with solar panels for renewable power production being vertically attached to the building.
In order to help the world reach net zero and green energy goals, we blend manufacturing tradition and energy innovation to deliver renewable technologies, products and services of the highest quality and performance – we are deliberately committed to manufacturing our façade panels in Hamlar, in the Donau-Ries region of Bavaria. As a family company with strong convictions, we are therefore bringing the solar industry back to Germany and offering a flexible “Made in Germany” solar-active façade system – combined with an experienced and highly skilled network of international partners, collaboratively working on making the energy transition reality.
