Direct Mounting with the new S-5!® PV-Kit 2.0

S-5!® has developed the new and improved PV-Kit 2.0 as follow-up of the PV-Kit Alu, which allows a more efficient and faster installation. The S-5!® Kit 2.0 is offered pre-assembled with either the MidGrab or EdgeGrab module clamp. The kits comes with a thread lock on the mounting studs so that the standoff can be tightened from top down bolt with one tool. This eliminating several assembly steps and significantly reducing installation costs.

Installation Instructions S-5! PV-Kit 2.0:

Due to the mounting recommendations of most module manufacturers, the modules should be installed at right angles to the seam. The clamping range of the modules must be observed. Therefore, please also observe the specifications and installation instructions of the respective module manufacturer and the following general instructions for planning and installation. The MidGrab module clamp can also be used as an end clamp, which makes material planning and mounting on the roof much easier. Please observe the following installation steps accordingly:

  • At the beginning a first row of S-5! Mini clamps must be pre-assembled parallel to the eaves in a straight line per module width. The S-5! Mini clamps, that are suitable for the respective seam type, must be mounted on the seam according to their installation instructions (with a tightening force of 15 – 17 Nm. For roofing made of galvanized sheet steel with a thickness of more than 0.7 mm with 18 – 20 Nm). (1).
  • Then fix the module support disc on the Mini-clamp with the stud of the pre-assembled MidGrab module clamp (do not screw in completely) (2).
  • Position the modules on the module support disc at the central elevation (3a)
  • Then pre-assemble the next row of Mini clamps and MidGrab-module clamps on the other edge of the modules towards the ridge for the first column (both not yet tightened) (5).
  • Then fix the MidGrab module clamps of the first row with a tightening force of 14-15 Nm on the Mini-clamps flush with the module frame (3b, 3c + 4).
  • And then fasten the Mini clamps on the other edge of the module according to their installation instructions to the seam (with a tightening force of 15 – 17 Nm. For roofing made of galvanized sheet steel with a thickness of more than 0.7 mm with 18 – 20 Nm) (6).
  • Repeat steps 3 – 6 for further assembly of the modules in the first column.
  • After the first column is complete repeat the above points 1-6 to build each column in the array.

When installing modules in a row from the eaves to the ridge, separation is necessary after a maximum of 10 modules in order to limit deformations due to thermally induced elongation of the installed materials. Afterwards, a new row must be started.

The number of clamps and PV kits should not be less than the number of fixing points of the metal covering and should be increased with a safety factor. Please note that these are only suggestions. Wind dynamics and statics are complex and S-5! therefore recommends that the planned PV installation be checked by a qualified professional who is responsible for wind influences and the planning and construction of and on metal roofs.

Please note in general:

Please make sure that the load coming into the clamp will be taken by the structure of the roof. Assumption is that the determination has been made that the roof to which the S-5! clamps will be attached is structurally adequate. Any loads imposed on the S-5! clamps will be transferred to the panels. Panel seams must have sufficient flexural strength to carry these loads. Panels must also be adequately attached to the building structure, and the structure must be sufficient to carry these loads. In particular, the snow and wind loads, the additional loads from the installations attached to the clamps, as well as the increased loads in the edge and corner areas of the roof construction must be taken into account. A sufficient number of clamps must be provided. For statically relevant clamps, a distance of at least
500 mm from the end of the standing seam profile must be maintained. RoofTech, the makers and distributor of S-5! clamps make no representations with respect to these variables. 
It is the responsibility of the user to verify this information, or seek assistance from a qualified design professional or stress analyst, if necessary.

Responsible for the stability of a building structure is the building owner or the owner or operator. The installer of the system is responsible not only for the system but also for the roof on which the system is installed. Whoever installs a system on an existing roof without having checked the stability beforehand, violates existing law! For critical installations, inquire for specific test data of ultimate tensile load on specific panel materials and seam types. The sufficient holding force of the roofing to the supporting or substructure must always be ensured. The sufficient holding force of the roofing on the supporting or substructure must always be guaranteed. Proof must be provided by the customer or installer. In cases of doubt, a structural engineer must be consulted to determine the loads and its effects.  

Please note the installation instructions of the respective S-5!® clamps and the other products used! Mounting the clamps take care that the set screws and bolts are tightened with the right screw tension as written in each installation instruction (also available under “Information” and on the homepage of S-5!: www.s-5.com). When tabled values are used, screw tensions should be verified and factors of safety should be used as appropriate.

When mounting rigid objects such as rails, pipes, cable trays, etc. on the clamps, these must be separated at regular intervals (max. 3m) in order to limit deformation due to thermal length changes.The thermally induced change in length of the roofing must not be hindered!

With some roofs made of profiled sheets (e.g. with round bulb seams, snap seams, RibRoof seams, etc.), it must be ensured that the clamps in the sliding area of the sheets are not mounted on or next to the holders of the roofing. In the case of double standing seam roofing, the S-5!® E and B clamps can, under certain circumstances, hinder the thermally induced length change of the sheet if, despite the high clamping point of the S-5!® E and B clamps, the foot of a sliding clip extends into the clamping area of the clamp. In this case, the S-5!® E and B clamps should be placed at a distance of 25 mm from the sliding clips.

In the case of handcrafted metal roofing on wooden formwork, the edge and corner areas should not be covered with modules due to the limited load-bearing capacity of the roofing and the adhesives. In the central area, the skipping of seams are usually not possible. Therefore we recommend to install clamps on each seam. The installation of PV systems represents a punctual load entry, therefore we recommend reduced clip distances and screwed clips. The mounting and fastening of the clamp should be carried out between the clips to achieve an optimal load sharing.

The material properties of the respective metals, the combination with each other as well as the installation instructions and regulations of all manufacturers involved (including those of the metal roof) must be observed.

The suitability for the intended use is checked by the user himself. If technical details are not described separately, this does not release the company carrying out the work from its obligation to check the individual case and clarify the correct technical facts beforehand.

It must be ensured by the planner and the specialist company responsible for the installation that the planning and installation are carried out strictly in accordance with the national and site-specific building regulations, occupational safety and accident prevention regulations, standards and environmental protection regulations. Every person who plans and installs with our products is obliged to inform himself independently about all rules and regulations for technically correct planning and installation and to observe them. This also includes obtaining the current status of the necessary rules and regulations.
