（16）Cables should be fixed in the area not exposed to direct sunlight to prevent cables aging.
（17）Protective measures must be taken in the process of installation to avoid force extrusion or impact on
the modules.
（18 ）When installing modules on roof mounted structures, please try to follow the “from top to bottom”
and/or “from left to right” principle, and don’t step on the module. This will damage the module and would be
dangerous for personal safety.
（19 ）The design loading of modules have been evaluated by TUV according to IEC61215 with 1.5 times
safety factor; The mechanical load bearing is dependent upon the mounting methods used and failure to follow
the instructions of this manual may result in different capabilities to withstand snow and wind loads;The system
installer must ensure that the installation methods used meet these requirements and any local codes and
regulations.
（20 ）Installation should be in accordance with Australian installation standards AS3000 wiring rules and
AS/NZS 5033.
（21 ）We recommend that you insure your solar system against natural hazards (e.g. against lightning
strikes).
5.2、ENVIRONMENT CONDITIONS AND SITE SELECTION
ZNSHINE SOLAR module should be installed in the following environmental conditions.

Remarks: The working environment temperature is the monthly average maximum temperature and
minimum temperature of the installation site. The mechanical load bearing capacity of the solar PV modules
determined based on the installation method. The professional solar PV system installer must be responsible for
calculating the solar PV system machinery when designing the solar PV system load bearing capacity.
If you are planning to use the PV modules where the water damage (Humidity: ＞85RH%) may be possible,
please consult with ZNSHINE SOLAR technical support firstly to determine an appropriate installation method, or
to determine whether the installation is possible.
The modules are certified according to the norm IEC 61215 and others for safe operation in moderate
climates. The operator needs to consider the effect of the high altitude on the operation of the module, when the
modules are installed at high altitude. The maximum altitude allowed for PV Module installation is 2000m.
For most places, PV modules should be installed where the sunlight can be maximally acquired throughout
the year. In the Northern Hemisphere, the PV modules should typically face south, and in the Southern
Hemisphere, the PV modules should typically face north.
When selecting the installation location, avoid areas with trees, buildings, or obstacles because these objects

- 10 - Document No.：QES/ZX-RD-III033A
www.znshinesolar.com
will form shadows on PV modules, especially when the sun is at the lowest position on the horizon in winter. The
shadow will cause the loss of the output power of the solar photovoltaic system. Although the bypass diode
installed in the PV module can reduce this loss to some extent, do not ignore the shadow factor.
Position the modules to minimize the chances of shading at all times of the day. Try to install modules in a
location where there is rare shading throughout the year.
According to IEC 61701, salt mist corrosion testing of photovoltaic (PV), ZNSHINE SOLAR PV modules can
be installed in corrosive salt areas within proximity of the ocean or sulfurous areas. The module must not be
soaked in the water or in the environment (i.e., fountain, spindrift, etc.) where the module would touch water (pure
water or brine) for a long term. If the modules are placed in an environment of salt fog (i.e., marine environment)
or sulfur (i.e., sulfur sources, volcanoes, etc.), there is a risk of corrosion. It’s not recommended to install the
modules, when the distance is less than 100m ; and it’s recommended to install the modules with the anti-salt
function, when the distance is between 100m and 1km. So stainless steel or aluminum materials must be used to
contact the PV modules, and the installation position must be processed with anti-corrosion treatment.
According to IEC62716 “Ammonia corrosion testing of photovoltaic (PV) modules”, ZNSHINE SOLAR
modules can be safely installed in ammonia-heavy environments, such as farm, meadow and so on.
According to the surrounding environment of the project, use the appropriate protective measures to ensure
the safety of the module installation and reliable. For example, it needs to have around the windproof measures
like design of windbreaks in strong wind area.
The system design needs to have the lightning protection function, it must pay more attention especially in
the installation ground where are more lightning strike.
When installing PV modules on a roof, the roof must be covered with a layer of fireproof material applicable to
this class, and adequate ventilation must be ensured between the back of the module and the installation surface.
A safe working area also must be left between the edge of the roof and the external edge of the solar array.
In the case of residential installations on the ground, modules must be installed following local regulations,
e.g. using fence.
5.3、TILT ANGLE OF INSTALLATION
The installation of PV module string should be in the same orientation and the same installation angle.
Different installation directions and installation angles will lead to the mismatches in current and voltage which is
caused by different light absorption of different PV modules, this mismatch will cause the PV system power output
loss.
The largest power will be generated When direct sunlight on PV module. For modules which are installed on
the fixed brackets, the best installation angle should be selected to ensure the maximum power output can be
generated at winter time, if the angle can guarantee enough power output during the winter, it will make the whole
solar PV system in the rest of the year can have enough power output also.
Solar modules are recommended to be installed at an optimized tilt angle to maximize the energy output. For
detailed information on the best installation angle, please refer to standard solar photovoltaic installation guides or
consult a reputable solar installer or systems integrator. Dust building up on the surface of the modules can impair
module performance. ZNSHINE SOLAR recommends installing the modules with a tilt angle of at least 10°,
making it easier for dust to be washed off by rain. Any faults caused by and/or attributable to tilt angle less than 10
degrees are not covered by manufacturer's warranty. It is roughly equal to the latitude of the project site as a rule
of thumb, facing toward the equator. Optimized system designs must incorporate other local requirements.
Installation inclination refers to the Angle between the PV module and the ground plane, as shown in Figure
5-1.

5.4、INSTALLATION REQUIREMENTS FOR BIFACIAL CELLS MODULE
Under the certain installation conditions, the backside of bifacial cells module will also generate electricity
power after receiving the reflected light, which will bring additional power generation gain to the power station
system.
The shading on the module surface will affect the power generation much, the module should be installed in
the place where the module cannot be shadowed totally (such as the shadow from building, chimney and tree
etc.), and even the partially shading (such as the dirt, snow and aerial wire etc.) should be avoided.
The generation gain is related to the ground reflectivity, the module installation height to the ground, the array
spacing and the shadow shading to the module backside.
Generally speaking, the reflectance is various with the different ground (See table 5-3), and this will lead to
different power generation gain.

Due to the different ground clearance height will affect the power generation gain, it is recommended to install
the module at a height from 0.5m to 2m. See Fig. 5-2.

In the system design, besides the ground type and the module installation height to ground, the proper array
spacing and how to avoid shadow shading on the back need to be considered too, please consult with the
professional system designer.
5.5、INSTALLATION METHOD
5.5.1 MECHANICAL INSTALLATION AND WARNING
PV modules can be installed through bolt method and clamp method.The modules must be installed
according to the following examples and recommendations. If a different installation method is desired, please

D. Mounting with Clamps
ZNSHINE SOLAR has tested its modules with a number of clamps from different manufacturers, with a
mounting bolt of at least M8. The length of clamp ≥60mm, thickness ≥3mm. If the customer needs a different size
of clamps, it should be fully evaluated and approved by ZNSHINE SOLAR.
The clamp must overlap the module frame by at least 7mmbut no more than 10mm.
Use at minimum 4 clamps to attach modules to the mounting rails.
Modules clamps should not come into contact with the front glass and must not deform the frame.
Be sure to avoid shadowing effects on the solar cells from the module clamps.
The module frame is not to be modified under any circumstances.
When choosing this type of clamp-mounting method, use at least four clamps on each module, two clamps
should be attached on each long sides of the module (for portrait orientation) Depending on local wind and snow
loads, additional clamps may be required to ensure that modules can bear the load.
Applied torque should refer to mechanical design standard according to the bolt customer is using, ex: M8
16-20N.m(140-180lbf.in)
