Avoid any shading and heat build-up at the rear of
the module. Both can lead to significant losses in
yield!
3.2 Maximum series/parallel configuration
CAUTION
Only solar modules of the same type and output class
may be connected in series! The maximum system
voltage of the modules must never be exceeded!
To achieve the required system currents the modules
may be connected in parallel. Only modules of the
same type and voltage may be used. Ensure that the
specified permitted load capacity with regard to the
return current IR is not exceeded!
3.3 General
CAUTION
Mount the modules only on suitable support struc-
tures. These structures must ensure that no mechani-
cal stresses are transferred from the building (e.g.
the roof structure) to the module.
The minimum distance between modules is 5 mm to
allow for material expansion, but recommended dis-
tance between two solar modules is 20 mm to allow
wind circulation to reduce loads and improve module
ventilation.
The modules must be installed such that water flow
(particularly along the cable) towards the cable
gland at the junction box is prevented.
The connection cables between the modules and
towards the inverter must be installed such that the
closed connectors are not permanently in water. This
means, for example, that rainwater must be able to
drain from U-shaped profiles.
Use only the holes provided in the frame! Do not
drill, nail or weld the module frames. This may cause
the loss of warranty. Please contact Sunways Tech-
nical Service if module mounting procedure is not
clear.
3.4 Standard mounting
Each module must be secured at a minimum of
four points (mounting holes in the long sides - see
diagram in section 2, your Solar Modules). The frame
is structurally approved for mounting on the long
sides. Mounting on the short module sides must be
avoided. The maximum tolerance is 100 mm.

The modules were designed to withstand such a load
of 2400 Pa by wind forces (both positive and nega-
tive charge) and 5400 Pa due to snow load.
3.5 Other data
Bundling or concentration of solar radiation, for
example using lenses or mirrors, is prohibited!
Avoid covering the drainage holes in the module
frames.
For any maintenance and repair work produce a plan
documenting the module installation layout, includ-
ing serial number allocation and cable layout.
