How to choose suitable photovoltaic glass

This article explores the classification and applications of solar photovoltaic glass. Photovoltaic glass substrates used in solar cells typically include ultra-thin glass, surface-coated glass, and low-iron (extra-clear) glass.

With global attention on environmental protection and energy efficiency steadily rising, the demand for solar photovoltaic glass in both commercial and residential construction sectors has significantly increased. The desire to reduce energy costs and carbon footprint has driven the widespread adoption of solar photovoltaic glass.

These three products have entirely different characteristics and functions, leading to significant differences in their added value. Currently, the most widely used photovoltaic glass is high-transparency glass, known as low-iron glass or extra-clear glass. Iron in ordinary glass, excluding heat-absorbing glass, is considered an impurity.

Crystalline — Solar panels made with crystalline glass tend to have a thickness of 3 to 4 mm, which adds more stability. This glass has a unique rough surface, which enables the glass to bond well with the panel's EVA film for lamination purposes. Smooth glass can lead to gradual delamination.

Our selection includes Optiwhite and Starphire glass, both of which are low-iron glasses for solar applications. At Swift Glass, we offer reliable solar panel glass materials, with manufacturing capabilities including bending, CNC machining, thermal tempering, waterjet cutting, and more depending on customer needs.

The initial development and utilization of solar cells using glass, soon gained attention from countries like the United States and Japan, thereby accelerating the research, development, and application of low-iron, ultra-thin glass for solar energy purposes. Demand for solar photovoltaic glass has surged due to growing interest in green energy.
