Glass has existed for thousands of years and is widely used both in industry and in homes. It can be a transparent container for holding flowers, as well as a table, window, transparent wall, etc., and it has a certain aesthetic value while possessing use value. In industry, it is transparent, electrically insulated, and able to seal environmental factors. In addition, it has no tendency to react with most chemicals, which is also why it becomes an important component of solar panels. Protect solar panels and panels from physical pressure, dust, moisture, and the like, while allowing sunlight to enter.

Generally, the surface material of solar panels is glass, and the back is protected by an opaque plate such as PET or TPT, called a back plate. The structure is reinforced and fixed with aluminum alloy to enhance protection. A new process has emerged that uses glass on both the surface and back, known as double-sided glass solar modules, commonly known as double-glass solar panels. Replacing other opaque backplates with glass will make them more expensive and heavier.

Double glass solar panels have several advantages over standard silicon solar panels with plastic backplates:
Durability of double glass solar panels

We often see the label “Glass, handle with care” “It is commonly believed that glassware is fragile. In fact, this is not the case. Containers made of glass can be fragile in shape, but glass in the form of sheets can be very strong. The glass protective film on the front of our mobile phone is a thin sheet with a thickness of less than one millimeter, but it can be used well and continuously. The glass sheets used on high-quality solar panels are suitable for withstanding one inch of hail.” Hail can easily dent some parts of the car, but the glass can work well. The fragile points of glass mainly lie in the surrounding corners, such as when a mobile phone falls, and the glass protective film on the surface begins to crack from the surrounding corners.

Special Applications – Transparent Roofing Materials

Because they are transparent, double glass solar panels can be used as roofing materials that require partial light transmission, such as on balconies, car sheds, and so on.

Longer Life – Better Assurance
Because performance degradation is much slower than standard solar panels, the average life of dual glass solar panels is longer.
