Namibia glass glass pv modules

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.

Are glass-glass modules bifacial?

Despite the challenges of the glass-glass modules design, the increased reliability, subsequent 30 year warranty and transparent back enabled bifacial technology to exist.

How long will a glass-glass module last?

Therefore. over a 30 year lifetime it can be expected to still operate at 85% of the nameplate capacity. 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.

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.

What is the difference between tempered glass and glass-foil modules?

Compared to traditional glass-foil modules, which are about 18 kg, this is a 20% increase in weight. Although there is no standard on glass thickness, in general it is a more complex and expensive process to produce very thin, tempered glass. However, 2.5 mm glass thickness does allow for frameless designs, which can reduce costs dramatically.
