2.3 Mounting options
REQUIREMENTS OF ALL MOUNTING OPTIONS
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 have been 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 connection cables of the junction box do not run between laminate and mounting rails.
Modules bend under load. Therefore, sharp objects (e.g. screws, ballast stones, rail ends, rails with burrs or sharp corners) must
not be placed near the module backside so as not to touch the laminate under load.
Ensure that the junction boxes do not touch the mounting structure (e.g. shorts rails, ballast, etc.) or the rooftop under load.
Clamps or insertion profiles etc. must not touch the glass (even under load).
Unbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be removed or
avoided by technical measures.
Loads according to IEC 61215-2:2016 and UL 61730-2:2017 except for design loads lower than 1600 Pa which
do not fulfill the requirements of the standards. The test procedure is always according to IEC 61215-2:2016.
Design loads result from the safety factor 1.5.
Mounting options with clamps
The illustrated installation options apply for both horizontal and vertical module orientation.

Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed between the
CL1a
module and substructure).
Short mounting rails are permissible, if they overlap with the module less than 210 mm. Maintain a minimum
CL1b
distance (clearance) of ≥ 35 mm between frame bottom edge and roof top or ballast.
Minimum support depth of 15 mm is required on the back side of the module.
Distance between outer edge of module and middle of the clamp.
