Bei Varianten ohne vorkonfektionierte Dichtung m\u00fcssen EPDM-Streifen vor Montage auf die Blechoberfl\u00e4che aufgeklebt werden, um Wassereintritt zu verhindern.<\/p><\/details><details id=\"frage-10\"><summary><strong>10. Muss ich bei Fassadenanlagen etwas Besonderes beachten?<\/strong><\/summary><p>Ja \u2013 Fassadenanlagen sind besonders windlastbelastet. Deshalb ist eine Absturzsicherung vorgeschrieben, und die Montage sollte exakt gem\u00e4\u00df Anleitung erfolgen.<\/p><\/details><\/div>\n\n<div class=\"faq-container\">\n\n<details id=\"frage-11\">\n  <summary><strong>11. How is concrete drilled?<\/strong><\/summary>\n  <p>Use a drill bit suitable for the substrate. The depth depends on the type of screw. Blow out the drill hole and, if necessary, use injection mortar.  <\/p>\n<\/details>\n\n<details id=\"frage-12\">\n  <summary><strong>12. What are injection anchors or threaded rods with mortar?<\/strong><\/summary>\n  <p>These are mechanically set anchors in which a threaded rod is glued into a drill hole filled with injection mortar \u2013 ideal for heavy loads or soft masonry.<\/p>\n<\/details>\n\n<details id=\"frage-13\">\n  <summary><strong>13. What screw length should I choose?<\/strong><\/summary>\n  <p>The screw length depends on the thickness of the insulation material, the wall structure and the position of the rails. Rule of thumb: at least 50\u201370 mm anchoring depth in the load-bearing substrate.  <\/p>\n<\/details>\n\n<details id=\"frage-14\">\n  <summary><strong>14. How many fixing points do I need per module?<\/strong><\/summary>\n  <p>At least two per module side (i.e. four per module). For larger systems and high wind loads, the number may increase \u2013 static planning recommended. <\/p>\n<\/details>\n\n<details id=\"frage-15\">\n  <summary><strong>15. Can I also use hanger bolts in the wall?<\/strong><\/summary>\n  <p>Only if there is a load-bearing wooden structure behind the fa\u00e7ade. For concrete or brick, other screw systems or threaded rods are required. <\/p>\n<\/details>\n\n<details id=\"frage-16\">\n  <summary><strong>16. Are there special adapters for thermal separation?<\/strong><\/summary>\n  <p>Yes, so-called thermal break adapters made of plastic ensure thermally decoupled screw connections \u2013 important for insulated facades or passive house constructions.<\/p>\n<\/details>\n\n<details id=\"frage-17\">\n  <summary><strong>17. What to do if the wall is uneven?<\/strong><\/summary>\n  <p>Height compensation is achieved by precisely adjusting the bottom rail. The top rails can then be aligned horizontally. <\/p>\n<\/details>\n\n<details id=\"frage-18\">\n  <summary><strong>18. Are top rails available in different lengths?<\/strong><\/summary>\n  <p>Yes. PROFINESS offers short rails, medium standard profiles and continuous rails up to 6.60 m \u2013 ideal for different project sizes and requirements. <\/p>\n<\/details>\n\n<details id=\"frage-19\">\n  <summary><strong>19. How is electrical grounding carried out for wall mounting?<\/strong><\/summary>\n  <p>As with roof systems: equipotential bonding terminals between the module frame and\nmounting rails enable a conductive connection.<\/p>\n<\/details>\n\n<details id=\"frage-20\">\n  <summary><strong>20. What tools do I need for assembly?<\/strong><\/summary>\n  <p>Depending on the type of installation, you may need a hammer drill, open-end wrench, torque wrench, cordless screwdriver, spirit level, laser levelling device (if necessary) and injection mortar set.<\/p>\n<\/details>\n\n<\/div>\n\n<div class=\"faq-container\">\n\n<details id=\"frage-21\">\n  <summary><strong>21. How do I align several rows of modules so that they are visually straight?<\/strong><\/summary>\n  <p>Mark the module grid in advance using a laser or chalk line. Install the top rails precisely in alignment \u2013 ideally using a mounting gauge or alignment aid. <\/p>\n<\/details>\n\n<details id=\"frage-22\">\n  <summary><strong>22. Can modules be mounted seamlessly next to each other?<\/strong><\/summary>\n  <p>Yes. A gap of 20 mm between each module is required due to the centre clamps, but this is barely noticeable visually. <\/p>\n<\/details>\n\n<details id=\"frage-23\">\n  <summary><strong>23. How far can modules protrude from the fa\u00e7ade?<\/strong><\/summary>\n  <p>The distance depends on the rail and fastening system \u2013 typically 60\u2013100 mm between the wall and the module frame. Important for rear ventilation! <\/p>\n<\/details>\n\n<details id=\"frage-24\">\n  <summary><strong>24. Is vertical series connection possible?<\/strong><\/summary>\n  <p>Yes, with vertical module mounting. However, the cable routing must be adjusted accordingly \u2013 if necessary, with intermediate connectors or DC cable extensions. <\/p>\n<\/details>\n\n<details id=\"frage-25\">\n  <summary><strong>25. Does the wall need to be load-bearing or load-supporting?<\/strong><\/summary>\n  <p>Yes. The loads from the PV system must be securely transferred to the load-bearing wall. Cavities or insulation boards alone are unsuitable for direct mounting.  <\/p>\n<\/details>\n\n<details id=\"frage-26\">\n  <summary><strong>26. Can damage occur to the insulation?<\/strong><\/summary>\n  <p>No, provided that thermal adapters and correctly positioned fixing points are used. Do not insert screws directly into EPS\/XPS! <\/p>\n<\/details>\n\n<details id=\"frage-27\">\n  <summary><strong>27. How are the top rail and module frame electrically connected?<\/strong><\/summary>\n  <p>Via the terminals (e.g. Profiness centre or end terminals) with equipotential bonding terminals. These establish a conductive contact to the module frame. <\/p>\n<\/details>\n\n<details id=\"frage-28\">\n  <summary><strong>28. What to do with irregular fa\u00e7ade surfaces?<\/strong><\/summary>\n  <p>Adjust the rail height using laser measurement or a spirit level; if necessary, use different screw lengths or wall brackets.<\/p>\n<\/details>\n\n<details id=\"frage-29\">\n  <summary><strong>29. Can I also install the system on wooden fa\u00e7ades?<\/strong><\/summary>\n  <p>Yes \u2013 with suitable wood screws. Important: Pre-drill holes to prevent cracking. Observe the minimum screw-in depth (approx. 70 mm).  <\/p>\n<\/details>\n\n<details id=\"frage-30\">\n  <summary><strong>30. Are there any differences compared to roof mounting?<\/strong><\/summary>\n  <p>Yes. Wall mounting is more demanding in terms of statics due to higher slope drag forces and may require special approvals \u2013 only carry out installation using tested systems. <\/p>\n<\/details>\n\n<\/div>\n\n<div class=\"faq-container\">\n\n<details id=\"frage-31\">\n  <summary><strong>31. Are there accessories for cable routing on the wall?<\/strong><\/summary>\n  <p>Yes. There are UV-resistant cable clips and channels that can be attached directly to the rail or module frame \u2013 neatly and securely. <\/p>\n<\/details>\n\n<details id=\"frage-32\">\n  <summary><strong>32. Do I need to observe any fire safety regulations?<\/strong><\/summary>\n  <p>Yes. In some federal states, special requirements apply to fa\u00e7ade installations (e.g. distance from windows). Consultation with an architect or building authority is recommended.  <\/p>\n<\/details>\n\n<details id=\"frage-33\">\n  <summary><strong>33. Is it necessary to clean the modules on the wall?<\/strong><\/summary>\n  <p>Depending on the orientation (e.g. north wall), more dirt may accumulate. Occasional cleaning with a soft water jet is recommended. <\/p>\n<\/details>\n\n<details id=\"frage-34\">\n  <summary><strong>34. Can I get coloured splints or covers?<\/strong><\/summary>\n  <p>Yes. PROFINESS offers black anodised rails and other mounting materials (including screw heads) entirely in black \u2013 for a harmonious fa\u00e7ade design. <\/p>\n<\/details>\n\n<details id=\"frage-35\">\n  <summary><strong>35. What needs to be considered when planning window areas?<\/strong><\/summary>\n  <p>Keep a sufficient distance from window openings (observe fall protection measures!)<\/p>\n<\/details>\n\n<details id=\"frage-36\">\n  <summary><strong>36. How can I even out unevenness in the insulation?<\/strong><\/summary>\n  <p>With adjustable wall brackets or different screw lengths \u2013 adapter plates can also compensate for small differences and guarantee precise alignment.<\/p>\n<\/details>\n\n<details id=\"frage-37\">\n  <summary><strong>37. Is there any indication of snow load on the wall?<\/strong><\/summary>\n  <p>Wall mountings are generally free of snow loads. Exception: modules above roof surfaces or in areas subject to strong wind drift \u2013 in this case, consult a structural engineer. <\/p>\n<\/details>\n\n<details id=\"frage-38\">\n  <summary><strong>38. Does the PV wall surface need to be ventilated?<\/strong><\/summary>\n  <p>Yes \u2013 there should be a gap of at least 6\u201310 cm behind the modules. This promotes cooling of the modules and extends their service life.  <\/p>\n<\/details>\n\n<details id=\"frage-39\">\n  <summary><strong>39. Is installation also possible on curved or sloping fa\u00e7ades?<\/strong><\/summary>\n  <p>Only to a limited extent. Shorter rails or individual brackets can be used for slightly curved surfaces. A customised solution is required for severely curved surfaces.  <\/p>\n<\/details>\n\n<details id=\"frage-40\">\n  <summary><strong>40.
