In our new company building in Neustadt which was being completed in 2011 you can see almost all techniques in function. Here we offer workshops and lectures for partners and customers.

We are proud of our assistance in the creation of the first largest Greenfield plant in Germany (2 MWp, Solarpark Lilienthal Neustadt). SIZ GmbH is still owned and managed by Wolfgang Müller and in our region a leading provider for photovoltaic.
