Mechanical Challenge of Frameless PV-Modules

Abstract

Frameless glass-to-glass PV-modules are exposed to a wide range of weather conditions, depending on their destined place of installation. Numerous aspects affect the mechanical stability as well as the mechanical durability under static and dynamic load conditions. These aspects are presented and discussed in detail. The structure of a glass-to-glass PV-module shows many similar features as a laminated glazing element in façades, which allows adopting knowledge from the structural use of glass in buildings. However, in some aspects, typical PV-modules show characteristic features, which significantly differ from standard laminated glass. The experience of using glass in buildings and the specific needs of the industry provide a fundamental basis for the development of innovative support and reinforcing systems. The research activities cover dynamic studies to assess the durability of PV-modules.
