General specifications for module installation

  • The modules may be installed up to a height of 2,000 m above sea level.
     
  • The installation of the modules on mobile units such as vehicles or ships is not permitted.
     
  • Unless special approval has been granted, the solar panels must not be installed in locations where aggressive environmental conditions prevail.
     
  • Solarwatt modules can be installed at a distance of ≥ 50 m from the sea. Solarwatt modules are salt spray resistant according to IEC 61701, but salt spray corrosion can occur in places where the module frame is connected to the mounting bracket or where the grounding is connected. When installing near the sea, the relevant parts and components should be protected by corrosion protection measures. 
    Contact Solarwatt for individual approval for deviating projects.
     
  • Have the structural suitability of the building for the installation of the modules checked by qualified personnel.
     
  • The modules must be mounted on suitable substructures that are designed to withstand the mechanical loads caused by wind, snow and the solar panels' own weight. The mounting system manufacturer's Notes also apply.
     
  • No mechanical stresses from the actual structure (e.g. roof truss) may be transferred to the solar panel.
     
  • The solar panels can be installed both vertically (portrait) and horizontally (landscape).
     
  • We recommend mounting all modules in a string at the same installation angle.
     
  • The maximum installation angle must comply with national standards and safety requirements. 
    Applications in Germany: When installing on a roof, the maximum installation angle to the horizontal must be less than 75° in order to comply with DIBt building regulations. 
    In Germany, the installation of the modules (except the Panel vision construct product line) is not approved as a façade system. For these applications, use our construct module portfolio and observe the specifications for Mounting variants and approved loads.
     
  • The use of modules (with the exception of the Panel vision construct product line) as overhead glazing in accordance with the technical rules for the use of linear glazing (in accordance with nationally applicable standards for glass in construction) is not permitted.
     
  • Ensure that sufficient rear ventilation can take place. A gap of at least 10 cm between the underside of the module frame and the surface of the roof or wall is recommended so that the cooling air can circulate around the rear of the module. This also allows condensation or moisture to dissipate. Also ensure that no flammable gases can escape or collect in the vicinity.
     
  • The modules must not be walked on. No objects may fall on them or be placed on the solar panel.
     
  • Do not hold or transport solar panels by the junction box or connection cables.
     
  • Do not install damaged solar panels.
     
  • Wear clean, grease-free and, if possible, silicone-free gloves during installation.
     
  • Ensure that the drainage openings of the module frames are not covered during installation.
     
  • Do not place any plug connectors in the frame.
     
  • No modules or parts of modules may be permanently shaded. Also avoid shading by the module clamps or the mounting system. 
    Please note that heavy soiling or waste (e.g. plants, bird droppings, etc.) can also lead to shading of the modules. See the Notes on cleaning the modules under Maintenance and servicing.
     
  • Maintain a minimum gap of 5 mm between the solar panels to allow for disconnect-free material expansion.
     
  • Ensure that there are no components such as cable ties, fastening elements, etc. between the mounting profiles and the back of the module.
     
  • Any use of lubricants is prohibited.
     
  • Unplugged connections must be protected from contamination of any kind (dust, moisture, salty aerosols, etc.) during transportation, storage and during the installation period. Only plugged connections fulfill their respective IP rating.
     
  • For system documentation, we recommend noting the positions of the serial numbers during module installation. 
     
  • A final test of the entire system must be carried out and documented in accordance with EN 62446.
