ATTENTION

• The loads in the table are related to the mechanical stability of the solar modules. The mechanical stability of the mounting system including clamps has to be evaluated by the system supplier. The Q CELLS listed test load values were determined with the following clamp parameters: clamp width = 40 mm and clamp depth = 10 mm. The system installer is responsible for the determination of location-specific load requirements.
• Ensure, that the sub construction does not touch the junction box (even under load). Ensure that the clamps or insertion profiles etc. do not touch the glass (even under load).
• Ensure, that the connection cables of the junction box do not run between laminate and mounting rails.
• Ensure, a minimum support depth of 20 mm on the backside of the module for IP1, IP2, CL2b and CL5. Ensure a minimum support depth of 10 mm on the front side of the module for IP1 and IP2.
• CL1, CL2, and CL3 with rails: Ensure that the module frame is fixed directly on the rail of the substructure (no spacer allowed between the module and substructure).
• Module bend under loads. Therefore, sharp objects (e.g. screws) must not be mounted near the module backside.
• Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm) for FB1 mounting.
• Use M6 corrosion-proof screws and washers (diameter ≥ 13.2 mm) for TB1 mounting.

 ELECTRICAL LAYOUT

Module Selection
For detailed key electrical data, please refer to the actual datasheet referring to the relevant module (available at www.q-cells.com).
Ä For maximum energy yields, mismatches of specified electric current (IMPP) of more than 5 % should be avoided for all modules connected in series.

Safety Factor
During normal operation, a module may generate a greater current and/or higher voltage than that determined under standardized test conditions. Please use a safety factor of  1.25 for the following:

• Calculating the voltage measurement values (VOC) of components
• Calculating the current measurement values (ISC) of conductors
• Sizing of control systems connected to the outlets of the solar modules
• Please follow the valid national guidelines for the installation of electrical systems.

Series Connection
The connection of modules in series is only permitted up to the maximum system voltage as listed in the applicable datasheet of all the relevant modules to be installed.

• Take into account all possible operating situations and all relevant technical norms and regulations when designing the system. It has to be ensured that the maximum system voltage, including all necessary safety margins, is not exceeded.
• Take the voltage limit of the inverter into account when determining the maximum number of modules in the string.

Parallel Connection
Modules may be damaged by the occurrence of reverse currents (caused by module defects, ground leaks or defective insulation).

• Ensure that the maximum reverse current load capacity indicated in the data-sheet is met.
  In order to limit reverse currents that may occur, we recommend using the following safety options:

1) Layout with a limited number of parallel-connected strings :
Without undertaking further current blocking measures, a maximum of two module strings may be operated in parallel on a single inverter or MPP tracker.

2) Layout with string fuses :
Place fuses for each string of modules at the plus and minus ends.
Use PV-fuses according to IEC 60269-6. Observe the maximum permitted number of strings as indicated in the specifications provided by the respective string fuse manufacturer and the technical guidelines.

NOTE!
When installing different product versions, the lowest minimum permitted reverse current load capacity applies.
Inverters
Inverters with or without transformers may be used.
