Can I also install the system in a single row?<\/strong><\/summary>\n  <p>Yes, especially for small roofs. Ensure correct ballasting. <\/p>\n<\/details>\n\n<\/div>\n\n<div class=\"faq-container\">\n\n<details id=\"frage-21\">\n  <summary><strong>21. What clamps are used to attach the modules?<\/strong><\/summary>\n  <p>Conventional middle and end clamps that are screwed into press-in nuts located in the frame. They are suitable for all standard module frame thicknesses. <\/p>\n<\/details>\n\n<details id=\"frage-22\">\n  <summary><strong>22. Can Klickfix clamps be used on flat roof systems?<\/strong><\/summary>\n  <p>No. We use conventional clamps and screws for our flat roof systems. <\/p>\n<\/details>\n\n<details id=\"frage-23\">\n  <summary><strong>23. Do I need an additional slot nut for flat roof racks?<\/strong><\/summary>\n  <p>No, the screw connection is made in the existing press-in nuts in the frame.<\/p>\n<\/details>\n\n<details id=\"frage-24\">\n  <summary><strong>24. How do I neatly finish a series of modules?<\/strong><\/summary>\n  <p>With end clamps. Wind deflectors are also installed on south-facing systems. <\/p>\n<\/details>\n\n<details id=\"frage-25\">\n  <summary><strong>25. When should I use wind deflectors?<\/strong><\/summary>\n  <p>With our south-facing systems, you need one wind deflector plate per module. It minimises wind loads under the modules. <\/p>\n<\/details>\n\n<details id=\"frage-26\">\n  <summary><strong>26. How do I attach the wind deflectors?<\/strong><\/summary>\n  <p>With the screws provided in the rear support of the frames. Press-fit nuts for\nscrew connections are also already provided here. <\/p>\n<\/details>\n\n<details id=\"frage-27\">\n  <summary><strong>27. Do the wind deflectors need to be earthed?<\/strong><\/summary>\n  <p>Yes, it is advisable to earth the entire system \u2013 please contact your electrician. Profiness offers components for earthing flat roof systems. <\/p>\n<\/details>\n\n<details id=\"frage-28\">\n  <summary><strong>28. What are row connectors and what do I need them for?<\/strong><\/summary>\n  <p>They connect several module carriers together \u2013 for mechanical stability and minimal ballasting.<\/p>\n<\/details>\n\n<details id=\"frage-29\">\n  <summary><strong>29. How many modules fit into a typical east\/west row?<\/strong><\/summary>\n  <p>That depends on the space available on the roof. Please feel free to use our enquiry form. We will plan your system free of charge.  <\/p>\n<\/details>\n\n<details id=\"frage-30\">\n  <summary><strong>30. Can I also raise only one side (e.g. south)?<\/strong><\/summary>\n  <p>Yes. The South system is designed for single-sided mounting with a 10\u00b0 or 15\u00b0 inclination. <\/p>\n<\/details>\n\n<\/div>\n\n<div class=\"faq-container\">\n\n<details id=\"frage-31\">\n  <summary><strong>31. What is the Firstsystem?<\/strong><\/summary>\n  <p>A roof-parallel ballast system that is connected via the roof ridge.<\/p>\n<\/details>\n\n<details id=\"frage-32\">\n  <summary><strong>32. How does the Firstsystem differ from the normal East\/West system?<\/strong><\/summary>\n  <p>In the ridge system, the modules are aligned parallel to the roof, meaning that the angle of the roof determines the angle of the modules. East-west systems are designed for flat roofs, with a standard module mounting angle of 10\u00b0. <\/p>\n<\/details>\n\n<details id=\"frage-33\">\n  <summary><strong>33. What is the Alpine system?<\/strong><\/summary>\n  <p>A particularly stable flat roof system for high snow and wind loads. Designed for maximum load-bearing capacity (e.g. in alpine regions).  <\/p>\n<\/details>\n\n<details id=\"frage-34\">\n  <summary><strong>34. When should I use the Alpine system?<\/strong><\/summary>\n  <p>In regions with high snow loads (e.g. snow load zone 3) or strong wind pressure.<\/p>\n<\/details>\n\n<details id=\"frage-35\">\n  <summary><strong>35. Are there any special requirements to consider for first or alpine systems?<\/strong><\/summary>\n  <p>Yes. However, these are two fundamentally different systems. We automatically take all relevant factors into account in the individual planning we create for your system.   <\/p>\n<\/details>\n\n<details id=\"frage-36\">\n  <summary><strong>36. How large must the row spacing between module rows be?<\/strong><\/summary>\n  <p>This varies depending on the system. You can find the grid dimensions for our systems in our brochures and installation instructions. <\/p>\n<\/details>\n\n<details id=\"frage-37\">\n  <summary><strong>37. Is there a maximum length per module row?<\/strong><\/summary>\n  <p>Yes. For a maximum of 12 modules, row breaks should be planned to allow for thermal expansion of the material.  <\/p>\n<\/details>\n\n<details id=\"frage-38\">\n  <summary><strong>38. How is the cable routing implemented in flat roof systems?<\/strong><\/summary>\n  <p>With cable ducts or UV-resistant cable ties underneath the modules along the module supports.<\/p>\n<\/details>\n\n<details id=\"frage-39\">\n  <summary><strong>39. How can a clean module finish be achieved on small surfaces?<\/strong><\/summary>\n  <p>We have shortened systems that allow as many modules as possible to be placed even in small areas.<\/p>\n<\/details>\n\n<details id=\"frage-40\">\n  <summary><strong>40. Can I use the systems on small areas and garages?<\/strong><\/summary>\n  <p>Yes. Our shortened systems are ideal for small roofs. Pay particular attention to\nwind load and ballast carefully!  <\/p>\n<\/details>\n\n<\/div>\n\n<div class=\"faq-container\">\n\n<details id=\"frage-41\">\n  <summary><strong>41. How do I ballast correctly?<\/strong><\/summary>\n  <p>Always according to the design. Place concrete slabs (e.g. paving slabs) centrally on the designated ballast supports (ballast feet). <\/p>\n<\/details>\n\n<details id=\"frage-42\">\n  <summary><strong>42. What ballast weights are common?<\/strong><\/summary>\n  <p>This can vary greatly depending on the region, wind and snow loads, and other factors. The exact amount of ballast required is calculated on a project-specific basis. <\/p>\n<\/details>\n\n<details id=\"frage-43\">\n  <summary><strong>43. Can I also use water canisters or paving slabs as ballast?<\/strong><\/summary>\n  <p>Water canisters are not recommended. Only use weather-resistant, permanently dimensionally stable objects. Paving slabs are well suited.  <\/p>\n<\/details>\n\n<details id=\"frage-44\">\n  <summary><strong>44. What do I need to bear in mind for edge and corner areas?<\/strong><\/summary>\n  <p>The wind load is particularly high here. More ballast or even bracing may be necessary \u2013 please take individual planning into account. <\/p>\n<\/details>\n\n<details id=\"frage-45\">\n  <summary><strong>45. How is earthing carried out in flat roof systems?<\/strong><\/summary>\n  <p>Via equipotential bonding terminals on beams, terminals and series connectors \u2013 in accordance with VDE guidelines.<\/p>\n<\/details>\n\n<details id=\"frage-46\">\n  <summary><strong>46. Do I have to earth all module frames?<\/strong><\/summary>\n  <p>No, if all terminals with integrated earthing have been used and correctly screwed in place. For further information on earthing, please contact your electrician. <\/p>\n<\/details>\n\n<details id=\"frage-47\">\n  <summary><strong>47. What should I do if individual modules are heavily shaded?<\/strong><\/summary>\n  <p>Shorten the row or change its position. Shading significantly reduces the overall yield. <\/p>\n<\/details>\n\n<details id=\"frage-48\">\n  <summary><strong>48. How do I maintain the system?<\/strong><\/summary>\n  <p>Visual inspection once a year: Check the position of the modules, clamps, ballast, contamination and cable routing.<\/p>\n<\/details>\n\n<details id=\"frage-49\">\n  <summary><strong>49. Can I dismantle the system without leaving any residue?<\/strong><\/summary>\n  <p>Yes. The system is not usually screwed into the roof. Remove the ballast, take off the modules, loosen the supports \u2013 done.  <\/p>\n<\/details>\n\n<details id=\"frage-50\">\n  <summary><strong>50.
