Whether photovoltaic glass belongs to flat glass

Whether photovoltaic glass belongs to flat glass

Sep 30,2022

Photovoltaic glass is a kind of flat glass, I think so. Photovoltaic glass belongs to soda lime silicate glass. The difference between it and ordinary flat glass is that the requirements for transmissivity are much higher. In the production process, the content of iron, the main coloring element, should be very low. There are certain requirements for glass defects. There are also requirements for the embossing roller required for glass forming. These measures are to improve the transmissivity of glass. The rest of the glass composition is basically within the range of flat glass composition. It can be said that photovoltaic glass is a higher level glass variety in flat glass! The reason why photovoltaic glass has developed so rapidly in recent years is mainly because it can be produced by improving the flat glass. The technical requirements for photovoltaic glass production are not high, which leads to this result.

What are the standards for solar photovoltaic glass? What are the materials for making glass

Sep 30,2022

Standard for photovoltaic glass: tempered or untempered embossed glass and float glass can be used for solar photovoltaic glass. The iron content shall not be greater than 0.015%, the visible light transmittance shall be greater than or equal to 91.5%, and the direct sunlight transmittance shall be greater than or equal to 91.0%. The material of solar photovoltaic glass is quartz, which is abundant in the earth. In fact, sand is also quartz, but the quartz used to make solar photovoltaic glass must be of high purity. Raw materials for glass production: raw materials used in the production of photovoltaic glass raw sheets include quartz sand, soda ash, feldspar, dolomite, limestone, mirabilite, etc. Among them, quartz sand and soda ash are the main components in the material input, that is to say, the quality of both determines the quality of photovoltaic glass; As for limestone, dolomite and mirabilite, the requirements are not as high as those of quartz sand and soda ash.
