Gilching, Germany-based Donauer Solartechnik has added several new on-roof and in-roof systems to its Intersol product line.
The new on-roof mounting systems, Intersol Trapez Flex and Intersol Trapez Light, are designed to allow installers to quickly mount solar power systems on trapezoidal roofs. The Trapez Flex substructure enables the mounting frames of solar modules to be installed in a transverse, oblique or upright position. It also allows an elevated mounting of solar modules.
Thanks to its 12 holes for positioning the screws, the Trapez Light can be flexibly mounted on the raised beading of the trapezoidal roof. The Trapez Light mounting rail is approximately 40 cm long and is designed to be easy to handle, the company says.
The new Intersol InRoof, a roof-integrated photovoltaic system, combines the substructure and solar modules together in one system, as its mounting rails create a frame for the PV modules. Once the mounting rails are attached to the roof, the solar modules can be slid into place to form a closed module area with an all-glass optic, Donauer Solartechnik explains.
The impermeability of the system has been tested to DIN EN 12 208 standards and approved according to rain impermeability Class 8A. The newly developed Donauer InRoof system also complies with the new fire safety regulation DIN V ENV 1187-1, which goes into effect July 1, the company adds.
