Schott Solar and BASF have presented a new roof-integrated photovoltaic concept based on the Schott Advance Series, which uses only two parts: a specially developed, multi-functional pan made from the BASF resin Ultramid B High Speed and a frameless double-glazed module from Schott. The product, designed for large roof areas on industrial or agricultural buildings, is very light and easy to install. The one-piece plastic pan, which can be installed directly on the roof substructure of a building in place of conventional roofing, combines several functions and employs a new fastening method. After the pan has been fastened to the roof substructure, the only remaining step is to insert the rugged double-glazed module into the pan“s precision mounting system and secure it in position by means of an integrated latch. The Schott Protect Series PV module uses double-glazing technology for reliable protection against rain, hail and other adverse weather conditions. The double-glazed module also has handles made from Ultramid on the back. This makes it easy to transport the PV module, position it on the integrated support edges of the plastic pan and simultaneously secure it at all four attachment points quickly and without the need for tools. The pan is stackable, thus minimizing shipping volume. Channels integrated into the pan ensure that rainwater drains away easily. Additional channels in the pan“s structure facilitate the installation of electrical cables. Thanks to the large opening in the centre of the pan, the plastic part of the 1.7 m photovoltaic module weighs only 8 kg and has adequate back ventilation. As with a classical roof tile, specially designed edges permit overlapping with adjacent modules, providing further protection against rain. The dimensions of the double-glazed PV module, designed for large roof areas, combine exceptionally good product characteristics with a high efficiency per unit area. The integrative solution reduces the number of steps necessary for installation, with working direction during roofing left to the roofer. Thanks to the ease of handling, frameless double-glazed modules can be used, thus preventing the accumulation of dirt on the surface.
