Glass has been widely used in modern times and has always been a product with high market demand. By using specific processing techniques, we can not only fully utilize the characteristics of glass, but also compensate for its defects, no longer constrained by the natural properties of glass. For example, laminated glass not only provides thermal insulation, but also prevents fragments from splashing and injuring people, making it safe and reliable. Next, we will introduce the standards, functions, and characteristics of solar photovoltaic glass.
1、 What is the standard for solar photovoltaic glass
Photovoltaic glass is made of low iron tempered suede glass (also known as white glass). The commonly used specification in the photovoltaic industry now is a thickness of 3.2mm ± 0.3mm; The tempered performance meets the national standard GB9963-88, or the impact resistance of the packaged components meets the performance indicators specified in the environmental test method for ground silicon solar cell modules GB9535-88; In general, the transmittance should be higher than 90%; In the wavelength range of spectral response of solar cells (320-1100nm), the transmittance reaches over 91%, and it has a high reflectivity for infrared light greater than 1200 nm. This glass is capable of withstanding the radiation of ultraviolet rays from the sun without reducing its transparency. Glass meets or conforms to national standards GB/T9963-1998 and GB2828-87.
2、 Introduction to Solar Photovoltaic Glass
Solar photovoltaic glass is a special type of glass that can generate electricity using solar radiation by laminating solar cells, and has related current extraction devices and cables. It is composed of low iron glass, solar cells, film, back glass, and special metal wires. The solar cells are sealed between a low iron glass and a back glass through film, making it a novel high-tech glass product for construction. Using low iron glass to cover solar cells can ensure high solar transmittance. Tempered low iron glass also has stronger resistance to wind pressure and the ability to withstand large temperature differences between day and night. Widely used in various fields such as building curtain walls, photovoltaic roofs, sun shading, solar power generation systems, and more. The installation form can be open frame, hidden frame, or various profiles that match the curtain wall for installation.
