Distance between outer edge of module and middle of the clamp; consider further details below.
Loads according to IEC 61215-2:2016 and UL 61730.
Test procedure according to IEC 61215-2:2016 and UL 61730. Loads for these mounting options do not fulfill the requirements of the standards.
Rails must not be under the junction box.
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
CL1a at high loads (5400 / 4000 Pa): The clamp position is variable in the given range but the distance between the clamps
along the long side of the module (span) must not be larger than 1250 mm.
Ä
CL1b: Using of short mounting rails are permissible, if they overlap with the module less than 210 mm. Minimum height of the
short mounting rails should be ≥ 35 mm (clearance between frame bottom edge and roof top).
Ä
Ensure, that the subconstruction does not touch the junction box (even under load). Ensure that 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
A minimum support depth of 15 mm is required on the back side of the module for IP1, IP2, CL2b, CL3 and CL6b. The minimum
required support depth on the module backside for CL5 is 10 mm on long frame side and 15 mm on short frame side. For the
front side of the module for IP1 and IP2, this minimum support depth should be 10 mm.
Ä
For CL1a, CL2a and CL3: 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 load. Therefore, sharp objects (e.g. screws) must not be mounted near the module backside.
Ä
Unbalanced snow loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be removed
or avoided by technical measures.
Ä
Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm or ≥ 0.62 in) for FB1 and FB2 mounting. Mounting screws
and washers should have the same material properties.
