6 FAQs about [Elasticity of photovoltaic glass]

Which glass is considered a superstrate for a PV module?

We consider specialty thin glass (Corning Eagle XG®) as superstrate of the PV module, while a standard tempered Soda-Lime-Silica Glass (SLG) is considered as bottom support. The reliability calculations for the module were performed based on the stress magnitudes obtained from the FEA computations.

What are the optimal design parameters for a glass-glass PV module?

This study finds the optimal design parameters of the support structure consisting of two C-Chanel that support the Glass-Glass PV module having thin glass on top and SLG at the bottom. Based on analysis described here, it was found that optimal channel location from free edges is close to L/5 that gives mechanical reliability of 0.99.

Why is glass front sheet important for PV modules?

In addition to optical and environmental performance, the mechanical performance of PV modules is also of vital importance, and with the glass front sheet constituting a high proportion of the mass of PV modules, it also impacts on mechanical properties of the PV module composite.

Can SLS glass be used in PV modules?

SLS glass is ubiquitous for architectural and mobility applications; however, in terms of its application in PV modules, there remains room for improvement.
