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.

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.

What are the IEC 61215 requirements for double-glass modules?

The double-glass modules and the conventional modules with back sheet were submitted to twice the requirements of IEC 61215 standard , i.e. 400 thermal cycles (-40°C to +85°C), 2000 hours of damp heat (85°C, 85% R.H.) and 20 humidity-freeze cycles (+85C to -40C, 85% R.H.) after 50 thermal cycles.

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.

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.
