Installation Instructions S-5-PVKIT® 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 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. RoofTech 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.

S-5-PVKIT® 2.0 MidGrab module clamp can be used as a middle and end clamp, which greatly simplifies material planning and the installation process on the roof. The S-5-PVKIT® 2.0 is suitable for framed PV modules with frame heights of 30mm to 46mm. Installation is carried out using the S-5!® Mini clamps suitable for the standing seam roof or the Multi-Trapezoidal Holder MTH. Please take their installation instructions into account accordingly during the following installation steps:

  • 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) (5+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.

There should be no more than 10 modules per column in the PV Array to prevent accumulation of thermal movement. After the 10th module a gap should be provided before starting the next row with enough room to accommodate for the PVKIT edge grabs between the rows. A gap of at least 10 mm must also be maintained between the module rows in the horizontal direction.

Please also observe the installation instructions for the respective S-5! S-5!® clamp and our general installation instructions (download under Information or request).

For mounting with the Multi-Trapezoidal Holder MTH, an additional M8 lock nut with locking serration is required to fasten the threaded stud on the mounting bracket of the Multi-Trapezoidal Holder MTH.

Please note in general for installations with S-5! Clamps:

  • The respective product installation instructions must always be observed (included in every box and with every delivery or please request or download from our homepage). During the entire installation period, it must be ensured that at least one copy of the relevant installation instructions is available on the construction site to all those involved in the installation and that it is strictly observed during installation.

  • Installation with our products should only be carried out by specialists and specialist companies with qualifications for the respective installation and with experience in working on roofs. During installation, the warranties of all trades involved and of the roof as well as the respective regulations for work on roofs must be observed (e.g. the use of fall protection, scaffolding with safety gear from an eaves height of 3 m, accident prevention, insurance, etc.). The presence of two persons is mandatory for the entire assembly process in order to be able to guarantee rapid assistance in the event of an accident.

  • In the case of non-observance of our installationy instructions, or assembly of our products with components of competitor and in the event of the use and combination of further components which were not purchased from us, we shall not accept any liability for any resulting defects and damage. The warranty is excluded in this respect.

  • The individual types of S-5! clamp are designed as described for the respective seam and profile types. However, new variants of standing seams and profiles come onto the market regularly. To avoid possible damage, it is important to check the suitability of the clamps for the intended metal roof before installation.

  • With very few exceptions, the load-bearing capacity of each individual S-5!® clamp is stronger than the load-bearing capacity of the roof panels or the profiled sheets and their attachment to the supporting structure. This applies not only to the normal clamps but also to the S-5!® Mini clamps. Therefore, the weak points are usually not the clamps, but the roofing and its fastening.

  • The individual types of S-5! clamps are designed as described for the respective seam and profile types. However, new variants come onto the market regularly. To avoid possible damage, it is important to check the suitability of the clamps for the intended standing seam roof before installation.

  • 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 considered.

  • A sufficient number of clamps must be provided. For statically relevant clamps, a distance of at least 500mm from the end of the standing seam profile must be maintained. RoofTech and the makers of the 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 S-5!® clamps take care that the set screws and bolts are tightened with the right screw tension as written in each installation instruction (available in all boxes, on the homepage of RoofTech: www.rooftech.de and S-5!: www.s-5.com or please send us an inquiry). When tabled values are used, screw tensions should be verified and factors of safety should be used as appropriate. If you are missing important and necessary information, please request it from us.

  • During the entire mounting period, it must be ensured that at least one copy of the corresponding mounting instructions is available on the construction site to all persons involved in the mounting. In case of non-observance of our assembly instructions and in case of use and combination of further components not purchased from us, we do not assume any liability for resulting defects and damages. The warranty is excluded in this respect.

  • 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 folded 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.

  • When installing rigid objects such as rails, pipes, cable ducts, etc. on the clamps, they must be separated at regular intervals (max. 3m in the case of handmade standing seam roofs) in order to limit deformations due to thermally induced length changes (in lengthwise and horizontal direction).

  • In the case of handcrafted metal roofing on wooden formwork, the edge and corner areas should not be covered with PV-modules due to the limited load-bearing capacity of the roofing and the adhesives. In the central area, the skipping of seams is 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.

  • Please observe the country-specific legal and official regulations for snow retention. Depending on the location of the building, height of the terrain above sea level, roof shape, roof pitch, type of metal roof and the respective holding strength of the S-5! clamps, the suitable snow guard systems must be professionally calculated and designed.

  • 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. 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.

  • The installation of our products should only be carried out by qualified and professional specialists with experience in installing on roofs. During installation, the warranties of the installations, solar system, etc. and the roof as well as the respective regulations for work on roofs must be observed (e.g. the use of fall protection, scaffolding with safety gear from an eaves height of 3 m, etc.). The presence of two persons is mandatory for the entire installation process in order to ensure rapid assistance in the event of an accident. 

  • 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 and company 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.

  • For rooftop installations, the respective regulations for work on roofs must be observed (e.g. the use of fall protection, scaffolds with safety gear from an eaves height of 3 m, etc.). The presence of two persons is mandatory for the entire assembly process in order to ensure rapid assistance in the event of an accident.
