f|solar GmbH (Osterweddingen, Germany) now offers heat strengthened glass that is only two millimetres thick and has general technical approval (allgemeiner bauaufsichtlicher Zulassung – abZ). This was awarded by the German Institute for Building Technology (Deutsches Institut für Bautechnik – DIBt) in Berlin and is valid for five years. Heat strengthened and equipped with a robust and homogenous antireflective coating, f|solarfloat HT is optimally suited for use in glass-glass PV modules of the latest generation. As heat strengthened glass for the back of the modules, with holes for the electrical connections, f|ecofloat T is used. Of especial interest to module manufacturers: the technical approval also applies to sheets of glass with drilled holes, coatings and enamelling.
“Glass-glass photovoltaic modules have a particularly high yield stability and last for an extremely long time – they therefore provide additional value compared with traditional modules. Our two-millimetre-thick glass types are ideal for both the front and the back of the modules”, says Thomas Keyser, Managing Director of f|solar GmbH.
