(Munich/Eberswalde, May 15, 2013) The German-based solar system integrator Mp-tec GmbH & Co. KG is premièring its new aerodynamic, zero-penetration flat roof systems for flat and flat sloping roofs at Intersolar Europe 2013 in Munich, the world’s leading trade fair for the solar industry. The latest generation of the “Snowflake” system is ideal for roofs with low load reserves and is available in two versions: “Snowflake south” was designed for south-facing roofs, while “Snowflake east.west” is optimized for roofs with an east-west orientation.
The “Snowflake” low-ballast flat roof solution consists of just five main components, ensuring rapid assembly. The systems were also developed with a focus on reducing the use of materials, thereby optimizing their value for money. At German locations for example, the surface load per square meter is less than ten kilograms, including the module. The aluminum system enables module installation at five, ten, 15 or 20 degree angles. Other angle positions within this range are possible on request. The loft and ridge gaps provided for aerodynamic reasons simultaneously ensure good ventilation of the modules.
“Snowflake” makes possible the most efficient use of available space and requires only minimal shading distances, to the benefit of the system’s economic efficiency. As a result, the “Snowflake east.west” and “Snowflake south” systems, applied to the example location of Munich, allow the installation of 125 watts per square meter. The system is suitable for virtually all common module types with a U-shaped frame. On specification of the module type, mp-tec can supply a custom system with ballasting recommendation tailored to the module and location.
The system was tested by leading structural aerodynamics engineers in a wind tunnel and its snow and wind loads calculated in accordance with DIN 1055-3 and DIN 1055-4. By eliminating the use of UV-sensitive materials, the system’s service life is significantly increased. Mp-tec provides a 15-year guarantee on the substructure.
