6 FAQs about Double-glass module production disadvantages

Are double-glass solar modules reactive or non-reactive?

Furthermore, comparing to plastic backsheets (the back material of single-glass solar module) which are reactive, glass is non-reactive. This means that the whole structure of Raytech double-glass solar modules (two layers of glass and one layer of solar cells in the middle) are highly resistant to chemical reactions such as corrosion as a whole.

Why should you choose glass in a PV module?

The choice of glass in a PV module has become a key consideration in efforts to improve durability in the face of extreme weather conditions.

What changes are incorporated in glass-glass modules?

Another major change that is also incorporated for glass-glass modules is swapping EVA for polyolefins as an encapsulant. This is due to the free radicals produced during the cross-linking lamination process of EVA. While traditional backsheets are somewhat permeable to the free radicals, the double-glass module is not.

What is the difference between Raytech double glass solar modules?

Whereas for Raytech double-glass solar modules, with the increased strength brought by two layers of glass, a lot less deformation will happen in the solar cells, the possibility of microcracks formed on the solar cells will decrease significantly.

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.

Do PV modules have tempered glass?

Among the current module products on the market, only single-glass modules are equipped with tempered glass. The choice of front and shear materials is critical in determining the module's ability to withstand hail impacts. Over the past decade, the PV industry has experienced a great revolution.
