There is a clear distinction between single and double glass solar panels. This difference should be clear by this- .
The front surface of double glass mono solar cells has an emitter layer and the back side has a dark covering. Passivated Emitter and Rear. .
Typically, solar panels have a front glass panel and a back plastic sheet. These single-sided glass panels are supported by frames across the. 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. [pdf]
