Is tempered glass good for solar panels?
Firstly, tempered glass is up to four times stronger than standard plate glass. Secondly, tempered glass is considered safe. When it breaks, it will shatter into small pieces reducing the probability of serious injury. Both strength and safety are necessary for the installation of solar PV panels.
Solar applications require flat glass. So-called Pattern Glass is mostly used as front glass in crystalline modules, whilst float glass is used for both substrate and back glass in thin-film modules. Molten glass is slowly cooled and fed off from the motlen tin.
What are the characteristics of glass for solar applications?
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.
In thin-film technology, glass also serves as the substrate upon which the photovoltaic material and other chemicals (such as TCO) are deposited. Glass is also the basis for mirrors used to concentrate sunlight, although new technologies avoiding glass are emerging. Most commercial glasses are oxide glasses with similar chemical composition.
What is solar glass used for?
Solar glass is used for protection and as mirror. For solar applications, transmission and reflection characteristics, mechanical strength and weight are of particular importance.
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.
