What is a double glass module?

Double glass modules use double sided low iron tempered glass with solar cells laminated in between. Double glass modules are ideal for roofs, skylights and/or facades. Double glass modules can not only be used as a part of construction material for a building, but also as a source of electricity.

What is double glass photovoltaic module?

Preface To further extend the s rvice life of photovoltaic modules, double glass photovoltaic module has cently been develop d and st died in the PV community. Double lass module contains two sheets of glass, whereby the back sheet is made of heat strengthened (semi-tempered) glass to substitute the traditional polymer backsheet.

Can double glass modules be used as a source of electricity?

Double glass modules can not only be used as a part of construction material for a building, but also as a source of electricity. 0 to +5W positive tolerance for mainstream products. Certified to withstand high wind loads and snow loads (5400Pa). Anodized aluminum is mainly for improving corrosion resistance.

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 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.

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.
