Tempered glass uses low iron tempered suede glass (also known as white glass).
Nowadays, the common specification with thickness 3.2mm± 0.3mm is commonly used in the photovoltaic industry; performance Meets the national standard: GB9963-88,
or the shock resistance of the packaged module meets the performance indicators specified in the national standard GB9535-88, environmental test method of solar cell module in silicon ground; solar (320-1100nm), the light transmittance should be greater than greater than 91%, and there is a greater problem for infrared light above 1200nm. This glass is also resistant to solar ultraviolet rays and light transmission does not decrease.
Theglass meets or conforms to national standards GB/T 9963-1998 and GB 2828-87.
However, there are many types of photovoltaic glass. You can consult some information in this regard, such as the national standards for building materials
