What s inside a double-glass solar module

Double-glass solar modules are made up of two layers of tempered glass that cover both sides of the solar panel. As snow accumulates on a typical solar panel or people stomp on it (during installation), the solar cells bend dramatically, resulting in microcracks on the cells. .
