OPTIONS
REQUIREMENTS
All
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 have
been determined with the following clamp parameters: clamp width = 40 mm and clamp depth = 10 mm.
Ä
The system installer is responsible for the determination of location-specific load requirements.
Ä
Ensure that the connection cables of the junction box do not run between laminate and mounting rails.
Ä
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.
Ä
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).
Ä
Unbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased loads must be
removed or avoided by technical measures.
Ä
A minimum support depth of 15 mm is required on the back side of the module.
CL1a, CL3,
FB1, FB2
Ä
Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed between the module
and substructure).
FB2, TB1a,
TB2a, TB1b,
TB2b, mFB2
Ä
Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm) for mounting slots (Detail A, Fig.1) and M6
corrosion-proof screws and washers or bobtails for tracker slots (diameter ≥ 13 mm or 0.51 in; Detail B, Fig. 1).
Mounting screws and washers should have the same material properties.
TB2a, TB2b
Ä
Mounting rails need to extend beyond the middle of mounting holes by at least 17 mm (0.67 in).
mFB2
Ä
Mounting rails need to extend beyond the middle of clamps or middle of mounting holes by at least 20 mm.
Clamps must not extend beyond the mounting rails.

Definition of limited areas.
Fig. 4:
Push loads in relation to minimum clearance between
frame bottom edge and substructure.
NOTE
For a requested push load maintain a minimum distance (clearance)
between the bottom module plane (level of bottom frame leg)
and closest substructure element below solar module laminate.
The minimum clearance is defined by the maximum test push load
and the limited area where the substructure element is located
beneath the module (see figure 3 and 4).
