Why are glass-glass modules becoming more popular?

Another factor that backs the move to a glass-glass configuration is thinner glass that is getting cheaper. With thin glass getting cheaper and the products being mature, glass- glass modules are becoming increasingly competitive, even more as they allow module manufacturers to offer longer warranties.

What is a glass-glass module?

Glass-Glass module designs are an old technology that utilises a glass layer on the back of modules in place of traditional polymer backsheets. They were heavy and expensive allowing for the lighter polymer backsheets to gain the majority of the market share at the time.

How much does a glass-glass module cost?

As regards the modules, glass–glass modules (2 mm glass–2 mm glass) cost 1.1 €/W p for significant volumes (at least 100 kW), but this cost can be even higher for special (such as colored) modules. The other hardware costs are the same, whereas a very sensitive cost item relates to the framing systems.

How much does a glass module weigh?

The weight of glass-glass modules are still an issue, with current designs using 2 mm thick glass on each side for framed modules, the weight is about 22 kg, while 2.5 mm on each side will increase the module’s weight to 23 kg. Compared to traditional glass-foil modules, which are about 18 kg, this is a 20% increase in weight.

Why is glass/glass photovoltaic (G/G) module construction so popular?

Glass/glass (G/G) photovoltaic (PV) module construction is quickly rising in popularity due to increased demand for bifacial PV modules, with additional applications for thin-film and building-integrated PV technologies.

What are 985 glass/glass modules?

985 glass/glass modules are anchored to the roof’s metal sheets with special clamps, and reinforced with a metal profile along the larger side (b). Huiming Yin, Frank Pao, in Building Integrated Photovoltaic Thermal Systems, 2022 Module A and module B are both glass/glass modules in Figs. 9.17 and 9.18, respectively.
