True to the motto “less is more,” German Centrosolar Glas has reduced the minimum thickness of solar glass for photovoltaic solar modules by almost 30%, and at the same mechanical resistance thanks to process optimization. The thin glasses reduce the total weight of the solar modules, which simplifies the assembly and saves transportation and mounting costs.
The solar glass has a thickness of only 2.3 mm and 2.6 mm and is particularly suitable for glass-glass solar modules. Previously, single-pane safety glass could only be produced with a minimum thickness of 3 mm.
In a fragmentation test, the new thin glass from Centrosolar Glas is to single-pane safety glass standards.
The Centrosol thin glass first exhibited at the Intersolar Europe, Munich, also offers the advantage of higher light transmission. It moreover extends the operating life of the PV solar modules because glass is more resistant to environmental effects than a plastic back sheet. The thermal conductivity of glass is higher than a backing film, reducing the cell operating temperature of a glass-glass solar module and improving efficiency especially in hot climatic conditions. Moreover it offers aesthetic advantages: the thin glass sandwich gives the PV solar module a genuine high-tech character. What is more, the customer can match the colour of the glass backing to the roof.
The energy yield can be further increased by means of the Centrosol HiT Nano Power anti-reflective coating. This coating further improves the transmission properties and therefore the annual energy yield of a photovoltaic system by up to 6 %. Furthermore, the low-iron solar glass with anti-reflective coating exhibits hydrophilic surface properties, creating a degree of self-cleaning.
