Roof-Mounted Installation
Roof-mounted installation is usually the simplest and most cost-effective way to install solar modules on the roof of a house. The solar modules are mounted using a rail system. The rails can be mounted horizontally, crosswise or vertically on the roof. The rails are screwed to the rafters using rafter hooks, which can be made from aluminium or stainless steel. The modules are then connected to the rails at a distance of approx. 5 to 15 cm from the roof.
Which roofs are suitable for the rooftop installation?
- Sheet metal roofing
- Slate
- Corrugated sheets/roof panels
- Tile sheets (tiled roofs)
What are the advantages and disadvantages of rooftop installation?
The time required and the price are particularly manageable with rooftop installation. The distance from the roof also ensures good ventilation of the solar modules. Well-ventilated modules and sufficient distance from the roof covering increase the module output (efficiency).
In contrast to in-roof mounting, the visual appearance is often considered a disadvantage of rooftop mounting.
