Building-integrated photovoltaics (BIPV) are considered a key technology for the energy transition in buildings – and their installation is now picking up speed. According to “Deutsche Energie-Agentur” (German Energy Agency – dena) more than 10 gigawatts of solar power generation capacity were added in Germany in 2023 and 2024. A success that needs to be built upon because according to surveys by the Fraunhofer Institute for Solar Energy Systems, up to 1,000 gigawatt peak (GWp) could be installed on Germany’s available roof and façade surfaces; the PV needs in a completely renewable energy system would already be achieved at around 500 GWp. Glasstec asked the experts Prof.-Dr.-Ing. Ulrich Knaack (Technical Universities of Darmstadt and Delft) and Dr. Thomas Kroyer (Fraunhofer Institute for Solar Energy Systems – ISE) about how to deploy BIPV more often in future and the new solutions available.
