  • Page 7: Recommendations For Use

    The metal support structure for the photovoltaic modules should be connected to ground in the manner indicated in the Low Voltage Directive 93/68/EEC and 2006/95/EEC and National Electrical Code.
  • Page 8 Do not dismantle, modify or adapt the PV module. Do not remove any part or the identification label from a PV module installed by Siliken Modules S.L.U. If you do so, the guarantee will be invalid. Do not apply paint or adhesives to the back side of the PV module.

  • Page 9: Product Certificates And Guarantee

    Siliken photovoltaic glass-glass modules are tested according to EN:14449. Siliken provides a 10 year guarantee for the materials of the photovoltaic module and against any possible defects of the photovoltaic module due to the manufacturing process.

  • Page 11: By-Pass Diodes

    Siliken delivers its modules with by-pass diodes included inside the connections box. The photovoltaic cells have two operating modes: it operates as a current generator or as a current consumer. A cell exposed to solar radiation provides a current ranging between 6 and 8 amps with a potential difference of around 0.6 volts.

  • Page 13 From the moment that the failure in the diodes occurs and until they are replaced, the affected photovoltaic module(s) must remain disconnected from the other modules on the photovoltaic array, thus guaranteeing that the circuit remains open. In any event, the decision to change the diodes is the responsibility of Siliken.

  • Page 15: Protection Fuses

    Protection fuses Attention: Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions. Accordingly, the values of ISC and VOC marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings,...

  • Page 17: Warnings And Electrical Hazards

    Warnings and electrical hazards The installation, handling and maintenance of the photovoltaic modules must be carried out by qualified personnel duly equipped with individual protections. For information purposes, these protections include: safety boots with insulation for above 1000V, gloves with 1000V insulation, as well as a helmet and appropriate clothes.
  • Page 18 Warnings and electrical hazards Do not allow objects to fall on the photovoltaic module, and do not sit on, lean on, or walk on the photovoltaic module, on either side (glass or rear sheet), given that it could cause the cells to break and therefore significantly lower the power and energy performance of the modules.
  • Page 19 Do not place the installation near to any possible source of inflammable gases or vapors, since the photovoltaic modules can cause sparks just like any other electrical component. Always ensure the installation is equipped with protection devices against electrical hazards.
  • Page 20 PV modules can increase this risk in case of fire. WARNING: Failure to comply with the provisions of this section will lead to the loss of guarantee and the exoneration of Siliken from any type of responsibility for damage to property or injury to people.

  • Page 21: Current-Voltage Curves

    It must be noted that the voltage and current behaviour of the cells depends on the solar radiation and temperature. Therefore, the actual operating conditions of a photovoltaic module will depend on the region where the module is installed and the ambient conditions in that region.
  • Page 22 In general, we observe a decrease of the photovoltaic module power as the operating temperature increases, at a ratio of -0.43%/ºC. For example, a module of 221 Wp will lose 0.95 Wp for every additional °C in the cells.
