The mounting system must have a flat surface for mounting the panel and must not cause twisting or stress on
the panel, even in case of thermal expansion.
We also remind that the waterproofing of the roof is not ensured by the panels but by the panels mounting sys-
tem and that the drainage must be provided.
It is necessary to provide a space between the frame of the panels and the structure or the floor to avoid dam-
age to the cables and hydraulic fittings.
The panel mounting systems must be installed only on buildings that have been formally validated for structural
integrity, and which have been considered capable of supporting the additional weight of the panels and mount-
ing systems, by a certified building specialist or engineer.
The supplier of the mounting system must take into account the galvanic corrosion which may appear between
the aluminium frame of the panels and the mounting system or the grounding parts if they are made of different
metals.
The module is only certified when its original frame is completely intact. Do not remove or modify the module
frame in any way. Drilling additional mounting holes is likely to damage the module and reduce the strength of
the frame, and thus is not allowed.
The use of flanges and fasteners with additional grounding bolts or grounding connectors shall be in accord-
ance with this safety and installation instruction manual and according to the conditions of
Grounding and light-
ning protection [14].
The modules can be installed according to the following methods:
1. Frame holes: Attach the module to the structure using the factory-made mounting holes. It is recommen-
ded to use four M8x16 mm stainless steel screws with bolts, washers and lock washers for each module.
The maximum tightening torque of the bolts is 24 N.m.
2. Calipers or clamps : the brackets can be mounted on the longitudinal (longest side) or lateral (shortest
side) side of the module. The areas allocated to these clamps are specified in
Installation areas on the rails
of the mounting system [10].
Installers must ensure that the resistance of the clamps is sufficient given the maximum pressure to which
the module can be exposed. The clamps are not supplied by DualSun.
IMPORTANT
It is important to make sure that the clamping brackets do not distort the top of the aluminium
frame of the DualSun panel, this may weaken or even break the glass.
CAUTION
The tightening torque of the clamps must not exceed 24 N.m.
WARNING
The compatibility of the mounting system with the modules must be assessed before any in-
stallation, especially when the system does not use brackets or clamps.
