Photovoltaic double-sided glass installation

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.

Glass-glass module structures (Glass Glass or Double Glass) is a technology that uses a glass layer on the back of the modules instead of the traditional polymer backsheet. Originally double-glass solar panels were heavy and expensive, allowing the lighter polymer backing panels to gain most of the market share. Thanks to producers such as:

Double-glazed modules are characterized by increased reliability, especially for large-scale photovoltaic projects. They include better resistance to higher temperatures, humidity and UV conditions, and have better mechanical stability, reducing the risk of microcracks during installation and operation.

Most common configuration for Bifacial Solar Panels is double glass. And even when bifacial modules have not have Fire Class A, still is much more protect anti-fire than standard back sheet modules. Especially on residential roof solar installation bifacial glass glass technology is must be chosen.

Regarding the moisture issue, the main argument against double glass modules is addressed by the use of polyolefins as encapsulating substances. The problem is further solved by the execution, as confirmed by e.g. PVEL tests.

Double-sided modules generate solar energy from both sides of the panel. While traditional panels with an opaque back coating are single-phase, the bifacial modules reveal both the front and back sides of the solar cells.
