Aufdachsystem

An Aufdachsystem, often translated as a "roof-mounted system" or "on-roof system," refers to a construction or installation method where components are attached to the exterior surface of a roof. This is most commonly associated with photovoltaic (PV) solar energy systems, where solar panels are mounted directly onto the existing roof structure. Unlike integrated systems that replace roofing materials, Aufdachsysteme are typically installed over or on top of conventional roofing.

The primary advantage of an Aufdachsystem is its relative simplicity and cost-effectiveness compared to fully integrated solar solutions. Installation generally involves securing mounting rails to the roof rafters or sheathing, to which the solar panels are then affixed. This method can be applied to a wide variety of roof types, including tiled, metal, and asphalt shingles, offering a flexible option for many homeowners and businesses.

Considerations for an Aufdachsystem include the structural integrity of the roof to bear the additional weight of the panels and mounting hardware, as well as ensuring proper sealing to prevent leaks. The angle and orientation of the panels are also crucial for optimizing solar energy capture. Maintenance typically involves occasional cleaning of the panels and inspection of the mounting system. Aufdachsysteme are a popular choice for residential and commercial solar installations due to their practicality and widespread applicability.
