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. . The main difference between double-glass photovoltaic modules and single-sided glass solar panels lies in their construction and design, which can impact their durability, performance, and applications. These are known as Double-Glass designs (solar panels with double glass or glass solar panels). The reason they are called monofacial is that 'mono' means single or one and. . As the first layer of materials in the solar module structure, tempered glass can effectively protect the panel and solar cells against physical stress, snow, wind, dust and moisture etc, at the same time guaranteeing that the sunlight can go in. The backside is generally protected by an opaque. .
