Northern Hemisphere, the modules should typically face south, and in
the Southern Hemisphere, the modules should typically face north.
When choosing a site, avoid trees, buildings or other obstructions,
which might block the sunrays. When selecting a clamping or insertion
system, appropriate anticorrosive brackets should be selected
according to the specification of the module.
(12) Put the modules on the frame and tighten the screws after
putting on the underlying washers. Don't cover the drain holes with
other components when installing the modules. The junction box should
be placed at the top of the module in order to facilitate correct
positioning of ventilation holes.
(13)Don’t grasp the junction box or cables during the installation
process.
(14) In case of installing the module on a roof top, the roof top
should be made fire-resistant first. Do not use modules near equipment
or in places where flammable gases may be generated.
(15)In case of roof top installation, the PV array should fulfill the
requirements regarding fire resistance of the norm IEC 61730-2.
(16)The ambient temperature range at the location of installation
should not exceed -40°C ~+85°C.
(17) Do not connect/disconnect modules during load connection.
(18) If the modules are installed on the roof, the whole system
mounting should be installed around 20CM away from the roof. The
recommended standoff height is 20 cm. The PV array installation slope
should more than 5in/ft (127mm/305 mm) when modules are installed in
rooftop.
The module is in a minimum fire resistance rating of Class C
,
and the fire rating of this module is valid only when mounted in the
manner specified in the mechanical mounting instructions.
(19) If the component is installed on the roof, the structure must
have a high bearing capacity, common roof structure such as color
steel roofs, cement flat roofs, the glazed tile roof, etc.
(20) If the
modules have the area of the
salt crystals which exceed
5% of the modules on façade then should clean it up. We advice that
the
modules should cleanly at every turn.
(21) We suggested that the height of the module from the ground is
not less than 60cm, in order to prevent the hot –spot caused by the
weeds.
DANGER:
One single module may generate more than 30V DC
when its front is exposed to direct sunlight. If modules are
connected in series, the total voltage is equal to the sum of the
partial voltages of each module .A nominal open voltage or maximum system
voltage of 45 V or more may cause an electric shock, exist in the conspicuous
position of a module connection part. Therefore direct contact should be
avoided after installing a greater number of modules in series or parallel, in
order to avoid electric shocks.
CAUTION:
Please unpack the module in an
appropriate
environment, and use special
tools. The modules need to be kept water-proof
and damp-proof.
