Distance between outer edge of module and middle of the clamp.
Loads according to IEC 61215-2:2016.
Test procedure according to IEC 61215-2:2016. Mounting options do not fulfill the requirements of the standards.
ATTENTION
Ä
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 listed test load values for Q CELLS 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.
Ä
Ensure, that the subconstruction does not touch the junction box (even under load). The clamps or insertion profiles etc. must
also not touch the glass (even under load).
Ä
Ensure, that the junction box’s connection cables do not run between the laminate and the mounting rails.
Ä
CL1b: Minimum clearance between frame bottom edge and substructure: ≥ 30 mm, short rails are permissible if they overlap
with the module less than 210 mm.
Ä
A minimum support depth of 15 mm is required on the back side of the module for IP1, IP2, CL2b, CL3, CL4 and CL5. For
the front side of the module for IP1 and IP2, this minimum support depth should be 10 mm.
Ä
For CL1, CL2a 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).
Ä
The module bends under loads. Therefore, sharp objects (e.g. screws) must not be mounted near the module backside.
Ä
Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm or ≥ 0.62 in) for FB1 and FB2 mounting.
Module Selection
For detailed key electrical data, please refer to the actual data sheet
referring to the relevant Module (available at www.q-cells.com).
Ä
For maximum energy yields, mismatches of specified electric
current (I
MPP
) 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 standardised
test conditions. Please use a safety factor of 1.25 for the following:
•
Calculating the voltage measurement values (V
OC
) of components
•
Calculating the current measurement values (I
SC
) of conductors
•
Sizing of control systems connected to the outlets of the solar
modules
Ä
Please follow the valid national guidelines for the installation
of electrical systems.
Ä
Please refer to the latest revision of AS / NZS 5033 (including
all relevant amendments) and the Clean Energy Council
Guidelines (for Australia).
Series Connection
Connection of modules in series is only permitted up to the
maximum system voltage as listed in the applicable data sheet
of all the relevant modules to be installed.
Ä
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.
Ä
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).
Ä
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 :
Please refer to the latest revision of AS / NZS 5033 (including all
relevant amendments) for parallel string overcurrent protection
requirements.
2)
Layout with string fuses :
Use overcurrent devices (e.g. fuses) according to the relevant
standards in each string. Use gPV-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.
