Key takeaways:
Renusol presented its FS Pro 0 roof-parallel mounting system featuring a penetration-free installation concept for inclined roofs
The company also introduced new middle and end clamps compatible with module frames up to 50 mm wide
Its free PV-Configurator 3.0 software supports project planning, structural calculations, BOM generation, and price quotation based on site and roof parameters
Renusol Europe GmbH is a Germany-based mounting systems provider for residential rooftops, including pitched, metal, flat, and in-roof scenarios. It also offers a solution for open spaces, with a free-standing mounting system that doesn’t involve ground penetration.
At Intersolar Europe 2026, Renusol presented its latest mounting solutions and components. The focus was on its ‘roof-parallel’ mounting product under the FS Pro series, called FS Pro 0, which enables a penetration-free installation on inclined roofs. In this solution, the mounting rails are laid in parallel along the inclination on both sides of the roof and are joined by a ridge at the top of the roof. The ridge holds the mounting rails together. These rails can be pre-assembled before being laid onto the roof, along with clamps pre-fixed to the rails, which cuts down the total installation time.
Since the rails are laid on either side of the roof, the modules can also be fixed on both sides. In a different scenario where modules are mounted only on one side, the rails on the other side are compensated with ballast for the weight balance.
Renusol’s latest middle and end clamps have a maximum width of 50 mm, which makes them compatible with a wide variety of module frames. In addition to the mounting systems and components, the company also provides a free-to-use software called PV-Configurator 3.0, which helps a customer plan the complete project, including assembly, structural calculations, documentation of parameters and parts, within minutes.
The software takes input of the location and other parameters from which the wind and snow loads are determined and factored in. These loads can also be entered manually or selected from the predefined load category associated with a specific location. Additionally, the surroundings, number of site visits, and PV system service lifetime can be selected to estimate the loads and also the type of components to be used in the installation. For the system configuration, the tool considers roof properties, dimensions, obstructions, coverage, and substructure. Finally, the module type is selected from the tool’s database, or a custom module type is fed in. The tool then proposes the mounting system configuration based on the previous roof configuration and module inputs. In the proposed mounting system, the components, rail dimensions, and other aesthetic selections are made before a final schematic layout design is displayed. At the end, a BOM calculation and required parts are listed along with a price quotation of the project. The software can be accessed here for free.
