What is a double glass module?

The double glass module design offers not only much higher reliability and longer durability but also significant Balance of System cost savings by eliminating the aluminum frame of conventional modules and frame-grounding requirements. The application of double-glass modules covers multiple markets including utility, residential and commercial.

Why are double glass modules symmetrical?

Mechanical constraints on cells: the fact that the structure of the double glass modules is symmetrical implies that the cells are located on a so-called neutral line, the upper part of the module being in compression during a downward mechanical load and the lower glass surface being in tension.

Why are double-glass modules important?

Double-glass modules have increased resistance to cell micro-cracking, potential induced degradation, module warping, degradation from UV rays, and sand abrasion, as well as alkali, acids or salt mist.

Are double-glass modules flammable?

Under exposure of a strong burning fire, double-glass modules present a high degree of resistance to ignition, do not propagate fire to the roof deck or other building material, do not slip from their mounting position, and are not expected to produce any flying burning debris. (Fig. 10, 11)

Are double-glass modules safe?

In addition, because of less micro-cracks and less moisture ingress, double-glass modules present a much lower risk of so-called “snail track” generation. A double-glass module was designed to pass fire-safety class A certification and UL1500V system voltage certification.

What is a double glazed window?

The outer glass layer of a double glazed window acts as the first barrier against external elements. It protects the inner glass and insulating gas from the weather, preventing rain, wind, and debris from affecting the thermal performance.
