Advantages and disadvantages of double-glass transparent modules

What are the advantages and disadvantages of glass-glass modules?

Some key advantages of the glass-glass structure are: Glass-glass modules can also be frameless, which helps eliminate the cost of an extruded aluminum frame. However, glass-glass models with frames have a lower risk of breakage. As a result, most glass-glass modules come with frames in place.

What is the difference between glass-transparent backsheet and dual glass?

Along with the size increase, the module weight is also increasing. Compared with dual glass, the transparent backsheet can successfully decrease module weight and the difference between the glass-transparent backsheet module and the dual glass alternative increases with the growing module size.

What is a dual glass module?

Our dual glass modules use the same internal circuit connection as a traditional glass-backsheet module but feature heat-strengthened glass on both sides. We produce the back glass with a unique drilling technique that ensures the reliability of both the junction box installation and the module.

Are glass-glass modules frameless?

Glass-glass modules can also be frameless, which helps eliminate the cost of an extruded aluminum frame. However, glass-glass models with frames have a lower risk of breakage. As a result, most glass-glass modules come with frames in place. Compared with standard glass backsheet technology, framed modules with two layers of glass are heavier.

Why should you choose a glass-to-glass module?

Glass-to-glass modules boast superior durability and resistance to environmental stressors. The dual glass layers provide excellent protection against water ingress, UV degradation, and mechanical stress. This results in lower annual degradation rates (0.45% compared to 0.7% for glass-to-backsheet modules), ensuring better long-term performance.

What is the difference between a transparent backsheet and glass?

There is an obvious difference in ultraviolet transmittance of a transparent backsheet and glass. UV transmittance of a transparent backsheet is less than 1%, whereas that of glass is 40-50%.
