1.2.2.5 Tensile bending strength The tensile bending strength of glass is not a specific material parameter, but rather an indicated value which like all brittle materials is influenced by the composition of the surface being subjected to tensile stress.
2.2. Glass characteristics Glass-glass PV modules generally use 2–3 mm thick glass layers, since thicker glass layers negatively impact the module''s weight and costs, while trends are to reduce glass thickness to below 2 mm [ 10 ].
Unfortunately, glass-glass PV modules are, similar to regular PV modules, subject to early life failures. A failure of growing concern are defects in the glass layer (s) of PV modules. The scale of decommissioned PV modules with glass defects will increase with the development of solar PV energy [ 7 ].
8.4.7.1 Local optical distortions The local distortions of fully tempered and heat strengthened glass may differ from the specifications for plain glasses, as glass geometry, size and thickness may have a greater influence on bending than with the plain design.
