It doesn't have to be roof
In the early years, photovoltaic units were predominantly installed on the roof of the house, but the design options and the possibilities for integrating them into the building have since increased enormously. Nevertheless, the type of installation is still dependent of the type of building and the local circumstances.
|In this case, the photovoltaic panels are mounted on a special substructure around 5 - 15 cm above the roof. Because of the simple construction, costs are lower than with more complicated in-the-roof installation.|
|Aesthetically, integration into the existing roof area is the most elegant solution, but it has the disadvantages of poorer ventilation.|
|Here, the modules are mounted at an angle on a special frame to capture as much of the solar radiation as possible. Large unobstructed roof areas are suitable for flat-roof installation.|
|A distinction is made between cold and warm facades. With cold facades, the modules are installed subsequently in front of the facade and serve both for generating energy and offering protection against the elements. The term warm facade is used to describe an outer wall built entirely of photovoltaic modules that can assume all the desired functions, ranging from the "skin" of the building to heat insulation.|
|For this type of installation, large unobstructed areas of ground are needed. This type of photovoltaic system is particularly interesting for local communities and farmers.|
