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)

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.

Is the double-glass module ul790 certified?

It was demonstrated during extensive fire testing that the double-glass module offers a high degree of fire protection, and reached Class-A certification according to the criteria of UL790 .

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.

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.

What is a double-glass solar module?

ABSTRACT: Double-glass modules provide a heavy-duty solution for harsh environments with high temperature, high humidity or high UV conditions that usually impact the reliability of traditional solar modules with backsheet material.
