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.

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.

What is a dual-glass module?

Dual-glass type modules (also called double glass or glass-glass) are made up of two glass surfaces, on the front and on the rear with a thickness of 2.0 mm each. Some manufacturers, in order to reduce the weight of the modules, have opted for a thickness of 1.6 mm. DualSun has chosen to stay with a thickness of 2.0 mm for reasons explained below.

What is a double glass (Dual Glass) solar panel?

A double glass (Dual Glass) solar panel is a glass-glass module structure where a glass layer is used on the back of the modules instead of the traditional polymer backsheet. Double glass solar panels were originally heavy and expensive, but the lighter polymer backing panels gained most of the market share.

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 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.
