Silfab Installation Manual

Do not expose the modules to artificially
concentrated sunlight.
Do not walk or step on the modules.
Do not stand on, drop, scratch, or allow objects
to fall on the modules.
Do not lift the modules by the junction box or
junction box cables.
Do not install or handle the modules when they
are wet or during periods of high winds. Modules in
Silfab packaging should not be kept outdoors
exposed to moisture.
• Ensure that junction box cables are provided with
strain relief to avoid damage to the junction box,
maintaining a minimum bending radius of 50 mm at
all locations along the cable.
Do not leave cable connectors exposed in
adverse climatic conditions. Water and dust depos-
its inside the cable connectors can cause long term
damage.
A module with broken glass, torn or cut backsheet,
damaged junction box, connectors or cables pres-
ent electrical safety hazards and must be removed
from service.
The total voltage of modules connected in series
corresponds to the sum of the voltages of the
single modules; whereas connecting the modules in
parallel results in adding up the currents. Conse-
quently, strings of interconnected modules can
produce high voltages and high currents and consti-
tute an increased risk of electric shock and may
cause injury or death.
For installation, maintenance, or before making any
electrical connection or disconnection, ensure all
modules in the PV array are exposed to a light
intensity that is less than 400W/m2 as measured by
an accurate solarmeter/ pyranometer.
Methods to reduce solar irradiance when making
electrical connections or disconnections include:
• Covering the modules with an opaque cloth or
other non-abrasive material in order to shield them
from exposure.
• Making the connections during hours of low
intensity of solar irradiance (such as early morning
or late afternoon).
8. INSTALLATION
8.1 Module Mounting Overview
The fire rating of Silfab modules is valid only when
mounted in the manner specified in the mechanical
mounting instructions.
When installing Silfab modules, local building code
requirements and regulations must be adhered to at
all times. In case of roof mounting, the appropriate
system fire class rating of PV module with Mounting
system in combination with roof covering and slope
applications should be considered. Silfab modules
are Type 2 or Type 1 (only on request) modules.
Sufficient ventilation of the module backside is
required to maintain the Type 1 or 2 fire rating, and
therefore the mounting configuration (e.g. sufficient
clearance) should be adapted accordingly. The
recommended clearance distance is a minimum 10
cm (3 15/16”).
Select a site and configuration that maximizes direct
sunlight exposure and eliminates or minimizes
shadowing.
Avoid low tilt angles to prevent the accumulation of
dirt/debris along the module edge.
Modules must be spaced a minimum 10 mm (3/8’) a
part on all sides to provide space for thermal
expansion and to provide ventilation.
Do not drill any additional holes into the module
frames and do not cover the drainage holes.
Do not mount Silfab modules in a position
where the junction boxes are “upside down” (leads
facing upwards).
