Stop 1 - Institute for Solar Energy Research in Hamelin (ISFH)

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.

Stop 2: PAW

PAW offers individual solutions for the sector of heating technology and solar thermal systems, as well as domestic hot water technology and flat stations. The product portfolio includes compact, small systems for single-family houses as well as high-power and large-scale products for hotels or living quarters. When developing new products, PAW is paying special attention to the basic development and industrial processes of PAW products and customer solutions. PAW focuses on modular system solutions easy to operate, and the plug-and-play idea always ensures a quick and easy installation.

By joining this tour, you will get an insight into the PAWs developing department, the in-house laboratory, the testing area, the logistics as well as the infrastructure at the PAW production site. PAW will also shine a light on the individual production steps and departments the products run through in an industrial company like PAW – demonstrated on the solar transfer station Solex. Participants will also discover a small choice of further products from the solar technology range (SolarBloC, Solex, DrainBloC).

Stop 3 - Lemgo 5 MW Solar Thermal District Heating

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.
