Technical FAQs 4

What are the characteristics of glass for solar applications?

For solar applications the main attributes of glass are transmission, mechanical strength and specific weight. Transmission factors measure the ratio of energy of the transmitted to the incoming light for a specific glass and glass width. Ratio of the total energy from an AM1-5 source over whole solar spectrum from 300 - 2,500nm wavelength.

What are the advantages of glass based solar panels?

Coating: Thin layers of coating may be deposited on one side of the glass for anti-reflection, improved conductivity or self-cleaning. For solar applications the main attributes of glass are transmission, mechanical strength and specific weight.

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.

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.
