North Korea double-glass solar module specifications

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.

How to improve the reliability of solar module design?

remedy most of the reliability issues in PV module design. The traditional backsheet materials of conventional solar modules was replaced with toughened (heat strengthened) 2.5 mm-thick glass. To reduce the weight of the module, the front glass thickness was also reduced to 2.5mm(Fig. 1).

Can a frameless PV module withstand snow and ice?

A frameless double-glass module and a traditional PV module with a 3.2mm glass with an aluminum frame were both qualified to withstand heavy accumulations of snow and ice under a high pressure of 5400Pa up to 6700Pa. modules are connected electrically in series until a maximum string voltage of 600 volt or 1,000 volt is achieved.
