Abstract
PVT-Kollektoren verbinden Photovoltaik (PV) und Solarthermie in einem Modul. Dadurch kann das System zeitgleich Wärme und Strom erzeugen und erzielt eine flächenspezifisch höhere Ausnutzung der solaren Strahlung, verglichen zur separaten Installation der beiden Technolo-gien. Die Kühlung der PV durch einen Wärmeübertrager generiert zudem höhere elektrische Erträge und nutzbare Wärmeenergie. Um Fassadenflächen für diese Form der Energiegewinnung nutzbar zu machen, wurde ein modulares PVT-Fassadensystem entwickelt. Mittels lastabtragender Klebungen auf der Rückseite der PV-Module werden hohe gestalterische Ansprüche und die Revision der PV-Module ermöglicht. Die konstruktive Entwicklung des PVT-Fassadensystems erfolgt in einem iterativen Prozess, da sich die Geometrien von Wärmeübertrager, Klebefuge, Befestigungssystem und PV-Modul gegenseitig beeinflussen und aufeinander abgestimmt wer-den müssen, um die konstruktiven, energetischen und gestalterischen Zielstellungen zu erreichen.
Facade integration of a load-bearing bonded PVT collector. PVT collectors combine a photovol-taic (PV) and a solar thermal system in one single module. Therefore, the system generates heat and electricity simultaneously and achieves a higher utilization of the available solar irradiation per square meter surface area, compared to the separate installation of PV and solar thermal systems. By cooling of the PV with a heat exchanger, the system generates higher electrical yields and useful heat. A modular PVT facade system was developed to use the facade surfaces for this form of energy generation. Through load-bearing bonds on the back of the PV modules, high aesthetic demands and the possibility to demount the modules are achieved. The constructional design of the collector developed in an iterative process, since the geometries of the heat exchanger, adhe-sive joints, fastening system, and PV modules influence each other. In this way, constructional, energetic and design objectives are met.
