From Hamlar out into the world – innovation meets tradition

ENVELON offers an innovative system for solar active façades under the umbrella of the multinational Grenzebach Group. Since its founding, 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 sustainable energy directly on buildings over the long term.

In this context, we blend tradition and innovation to deliver products and services of the highest quality and performance – we deliberately produce our façade panels in Hamlar, in the Donau-Ries region of Bavaria. As a family business with strong convictions, we are therefore bringing the solar industry back to Germany and offering a flexible system “Made in Germany” – combined with an experienced and highly skilled network of international partners.

Our mission: we’re driving the vertical energy revolution

ENVELON is redefining photovoltaics. In the form of our solar façades, we offer a technology for climate-friendly electricity production. As such, they serve a dual purpose in the best sense of the word – ENVELON panels not only create an aesthetically pleasing building envelope, but also help achieve the energy revolution daily and unlock previously untapped potential.

For our active façades to have the greatest possible positive effect, we take a flexible 360-degree approach. This means that, in addition to manufacturing the façades, we can also offer customized planning services for the respective project, as well as turnkey installation. Through this integrated approach, architects and owners benefit from the entire expertise of the Grenzebach Group as well as our network – because this is the only way we can achieve sustainable success together.

Team future – we live and breathe the vision

Behind the ENVELON brand is a core team of experts with many years of experience in the solar and façade sector. Our engineers, project managers, and sales professionals are here to support you through every stage of your project. Each team member brings their own individual areas of expertise and skills to the table – the ideal way to effectively drive the vertical energy revolution.

We’re growing. Join our team!
