Technical Tour 2

The Institute for Solar Energy Research in Hamelin (ISFH) is an institute of the state of Lower Saxony, which is engaged in application-oriented research and development in the fields of photovoltaics and solar systems technology. The institute trains students from a wide range of disciplines during their final theses. During your visit you will get to know the latest solar collector and photovoltaic developments for applications in the facade as well as test stands for heat pumps and domestic hot water modules indoors and outdoors. Furthermore, you will visit the solar simulator as well as the spectral gonioradiometer.

In Lemgo in North Rhine-Westphalia, you have the chance to visit the third largest solar thermal system in Germany which was designed and built by EuroSun 2022 Gold Sponsor Viessmann. The plant produces more than 3.3 million kilowatt hours of heat from solar energy each year, equivalent to the heating needs of 150 households. The plant started up in March 2022 together with heat pump systems that have since contributed to a significant reduction in CO2 emissions in Lemgo -  around 1,800 t of CO2 annually. While on average each citizen in Germany consumes almost 10 t of CO2 yearly, consumption in Lemgo stands at just under 7t thanks to this combined system.
