INNOVATION | High Standard through continous improvement
50 years Spitzenberger & Spies


Due to climate change regenerative energy sources are becoming more and more important.
We produce test and simulation systems for photovoltaics and wind energy. Our devices accurately simulate factors such as day time dependent light intensity, the incidence angle of sunlight and temperature change within the photovoltaic cells.

In the area "Solar" we offer the following products:
