Munich Intersolar Europe 2012 will showcase the Intersol product line of Donauer Solartechnik comprising new in-roof and on-roof systems. The visitors will be provided with an opportunity of fitting the Intersol Trapez Flex and Intersol Trapez Light to a part of the roof in the exhibition.

The new mounting systems enable installation of solar power systems on trapezoidal roofs conveniently. Using the Trapez Flex substructure, solar module mounting frames can fitted in an oblique, transverse or upright position. Based on an adjustable trapezoidal sheet holder, the substructure can be adjusted to a specific width on the ground. Self-tapping screws are used to attach the Trapez Flex to the roof’s raised beading. The Trapez Light can also be mounted on raised roof beading using the twelve holes provided for screw positioning. The 40 cm width Trapez Light mounting rail enables easy handling on the roof.
The new in-roof system, Intersol InRoof is a roof-integrated photovoltaic system which integrates substructure and solar modules into a single system. The solar modules are slid so as to form a closed module area after the mounting rails are fixed with the roof. The system was tested for its impermeability according to DIN EN 12 208 and meets the requirements of new fire safety regulation, DIN V ENV 1187-1.
Donauer Powerrouter which consists of a single-phase inverter with a back-up and battery management system, is a key component of self-consumption solution. The device can be controlled through an Internet portal and allows complete utilization of solar power stored in batteries. The device can be installed easily and manufactured in two forms with the capacity of 3.7 and 5 kW respectively.
