40 years of solar technology – Made in Germany. We have been dealing with solar energy for over 40 years. Starting with solar air systems, which have been used in over 50 countries to date, we have long since grown up and have been completely independent of Grammer AG for over 15 years. For 20 years, our second mainstay has been the solar power sector, where we implement regionally and internationally turnkey PV systems, primarily on buildings. 6000 systems with over 100 MWp output show our current performance.
