Among the primary elements of solar glass are quartz sand, soda ash, limestone, dolomite, sodium nitrate, mirabilite, sodium pyroantimonate, aluminum hydroxide, and so on. Mostly serving as the network forming body, quartz sand typically makes up more than half of the composition of the glass.
Most solar panels use tempered glass, which is heat-treated to enhance its strength and durability. The composition of this glass typically includes silica, soda ash, and limestone. While this standard glass provides good protection, variations in composition can have different effects on efficiency.
For solar applications the main attributes of glass are transmission, mechanical strength and specific weight. Transmission factors measure the ratio of energy of the transmitted to the incoming light for a specific glass and glass width. Ratio of the total energy from an AM1-5 source over whole solar spectrum from 300 - 2,500nm wavelength.
Base-line commercial glass has a solar transmission of 83.7%. I.e. 16.3% of the sun's energy do not even get to the PV material. The energy loss is due - in equal parts - to reflection on the surface and absorption within the glass due to iron impurities. The density of glass is about 2,500 kg/m 3 or 2.5kg/m 2 per 1mm width.
