The flexible and light on-roof system for pitched roofs

The VarioSole is suited for all roofing types, all current PV modules and, thanks to height-adjustable mounting elements, even for roof areas that are not level. The installation of the few, partially already pre-assembled components is easy and fast. VarioSole is a rail system that is mounted on the rafters with special roof hooks. All that is usually necessary for the installation is to remove or slide up single tiles. Removing the entire roof covering is therefore not required.

Roofhooks for all roofings

The roof hooks are made of extremely resilient, yet at the same time light aluminium diecast. Due to their design, the roof hooks are especially rigid and stable. The rails that then fasten the modules in place with module clamps are mounted on these hooks.

VarioSole SE system components

1. Roof hooks for plain tiles

The VarioSole roof hook for plain tiles is made of high-quality stainless steel. The slotted line enables the compensation of unevenness on roofing surfaces. It is mounted on the rafter using the delivered wood screws admitted for use by the supervisory authority.

2. Basic Rail

The basic rail is mounted on the roof hook and holds the end clamp and the middle clamp for the installation of the PV module as well as the cross rail connectors. For only vertically installed PV modules, only horizontal basic rails will be required. The basic rails for horizontal and vertical installation are identical.

3. Rail connector

It is used to join several basic rails together. The rail connector is inserted into a premounted basic rail until it reaches the rivet. The rivet in the middle ensures that the connector is inserted in the two basic rails for the same depth.

4. Middle clamp

The middle clamp can be snapped in in each desired position of the basic rail section and holds the PV module. The height of the middle clamp can be adjusted in the frame height of the module using a hexagon socket screw.

5. End clamp

The end clamp is pushed on the section at the end of the basic rail and holds the PV module. The height of the frame can be adjusted by using the adjustable end clamp.

6. Cross rail connector

It is used for the horizontal installation of PV modules. The cross rail connector allows the vertical installation of further basic rails on the horizontal grid. Two connectors, each snapped in on the horizontal basic rail, hold the vertical rails on the left and on the right on the cross points.
